ECUtune Stage III development

[longassname]

Ok, we've started the process of physically developing the ECUtune SVX Stage III supercharger kit. We'll be posting the progress in this thread as we go so everything will be covered by the time we are through. I'm going to focus on posting the pictures and information as I have it rather than answering questions and overseeing the inevitable debates that will arise between members.

Today we have pictures of the disection of the intake manifold and measurements of the area where the supercharger head unit will be located.

This is what your engine would look like if it was a junk yard engine, on an engine stand, and pretty heavily stripped down. You can see the coolant manifold reaching accross the top of block to connect the heads. The height of this manifold is the same as the top of the bolt on the black iron bracket on the front of the engine.

And this is what your upper intake would look like if you sawed it into 3 pieces.
http://www.ecutune.com/posts/intake1.jpg
http://www.ecutune.com/posts/intake2.jpg
http://www.ecutune.com/posts/intake3.jpg

As you can see in the pictures the center section has been removed in order to make room for the supercharger. The supercharger will mount underneeth the intake manifold blowing up into it with the drive snout protruding forward and the pulley interfacing with the 6 rib belt.

We layed a piece of sheet metal cut the same size as our prospective head unit across the top of the block sitting flat on water manifold and the bolt on the cast iron bracket to create a flat surface from which to measure up to the manifold in order to determine clearances.

We layed a straight edge across the flange of the lower intake in order to determine it's height from the same piece of sheet metal.

Good Lord, that's gonna be one sweet setup when it's done. Who woulda thunk to chop the intake manifold in pieces to fit the S/C.

I'm gonna start saving my pennies now....should have enough saved up by 2010.

One question....where does the alternator go?

Okay, two questions. Are you going to sell these with precut manifolds and do a core exchange?

Wow... can I just say... wow.

Do you think this'll take more than 6 months? 'Cause that's how long it's going to take me to save up. :D

If it is only going to take you 6 months... than you are one of the lucky ones.:D I'm hopin' for... sometime down the road.:D

[IggDawg]

Truly impressive. I have to agree with the previous "crazy" statements.

[NomadTW]

:( it's so beautiful maybe by the time iget my next svx i will be able to afford one of those.

[SVXRide]

(okay, so this isn't the Hindenberg going down in flames, but who thought we'd ever see an SVX intake cut in three pieces!)

Michael,
Would you please post pics when you decide where/how you're going to plumb in your instrumentation for this "beast". I'm very interested in where the best places are for oil pressure and water temp. I'm guessing you'll tap the exhaust for EGT and A/F?
-Bill

[svxsubaru1]

Looks like the SVx will aculy have a decent aftermarket. Any idea on the cost?

[Matthewmongan]

5 G ($5000)

[Phast SVX]

400 crank horsepower for 5000 dollars(fuel pump, s.c., sc nose, pully, manifold, new alternator. injectors, management) i really hope they are making their money back. Thats alot of work and alot of supporting modifications. Im so pumped. Started saving myself.
phil

[TomsSVX]

looks like someone is making progress. This project is looking awsome. I am probobly one of the most excited to see this become a reality. What are we looking at in terms of reliability here though, is this sc gonna hold up longer than the vw coranno's or is this gonna be just a sweet setup w/ minimal failures and great reliability. Either way, sounds awsome and if you could come out with projected costs that are not as round in figures that would be great.

I'm thinking the same thing. This degree of developmental effort is rare for cars with huge aftermarkets like civics and WRXs... never mind cars with dry aftermarkets like ours. I'm very literal when I say I'm a little shocked at how much work is being put into this. It's certainly not a "straightforward application." I very much hope they pull a profit.

[Matthewmongan]

easy to clean with it all apart.

[longassname]

Just a couple pictures today. Today we cut out the separations between the runners so that the aircharge can move freely from the front to the back. These are just rough cuts but that's where all the work is. Because of the tight areas restraining where the cutting wheel would fit I had to disect the runners in chunks. The remainders of the cast walls and the ribs will be ground out smoothly.

http://www.ecutune.com/posts/intake2-1.jpg
http://www.ecutune.com/posts/intake2-2.jpg

[Subafreak]

That step looks like alot of work. Are you sure it wouldn't be eaisier to built a tubular manifold instead? Or something. Thats alot of cutting and rebuilding of the stock manifold.

[NikFu S.]

I was thinking the same thing, but fashioning a completely new, durable manifold of superior quality would require more machinery and effort, not that present company lacks any effort.
I just think it would be harder.

[Matthewmongan]

look at it in the terms of home instalation. i would never be able to put that on my car. it would be like going to the hospital for a kidney transplant and getting a kidney in a brown paper bag. the docs like "oh its not that hard"

I am sure you would get a maniflod already done then you would send in yours for exchange. If not its still worth it:D .

[longassname]

ok, here's the other half with the separations between the runners cut out but not ground out smoothly yet. I'm leaving the grinding for the metal shop to do. They are actually doing the grinding and forming (forming is the shaping of the new pieces) tomorrow. And expect to weld it together on Monday (big metal shops batch aluminum and stainless welding jobs separately so that on any given day they are only doing one kind of metal). There is also normally a two week backlog of work but I'm fortunate enough to be able to jump ahead in que which greatly speeds up the process for us.

so thats like me cuting out my old kidney and waiting six to eight weeks for a new one. :p works for me


seeing the manifold apart like that makes me want to 'carb' clean the inside of mine

[longassname]

These are pics of the jig that the intake will be welded on. The two cast sections taken from the old plenum are bolted to this jig when the new center section is welded in place. This both keeps everything lined up propperly and stopps the sections from being pulled out of level by welds.


This is the plate with the pilot holes drilled into it.
http://www.ecutune.com/posts/jig1.jpg

And here the holes have been redrilled to the propper bolt hole size.http://www.ecutune.com/posts/jig2.jpg

Thought I'd take the opportunity of having the plate to illustrate the vertical space or lack there of.

The air must get to the heads somehow, so why not use as much of the original ports as possible? That is a good alternative for many reasons, reliability and cost being two.

The Chevy TPI -Tuned Port Injection- was and still is popular due to 'the look'. Retaining the cast, curved [TPI] SVX intake runners to bolt to the head preserves the character and essence of the engine. That's perfect!

I must concede that the visuals are better than a turbo under the car. A supercharger in or under the spider still has the SVX look, times ten!

Great work Michael! CARRY ON!

Does this mean you don't have time to drag test Stage II?

OR, Shall we anticipate the SVX 'MATCH RACE' of the ages?

Your Stage II against the first Stage III?

[longassname]

Just got a call from the metal shop guy and both the forming and the grinding went as expected today. Looking good for getting the manifold back late monday.

[TomsSVX]

maybe a good suggestion would be to refer the use of J&S safegaurd knock system. I have been doing some reading up on this and sounds like a good investment. Anyway, just a thought

Michaels tuning is done with the stock ecu and his own map written to a stock rom. The stock knock sensors and JECS computer allow for flawless factory engine control on a supercharged motor.
J and S does kickass, it makes for a good timing control unit, and is perfect for piggyback setups.

Okay okay, if not then at least an M45.

It will be roots type right? So we can get some really cool hood design, like the supercharged 350Z's. :cool:

We're going to be using an innovative lm1 wideband o2 meter for our measurements when we start making our software adjustments for the new fuel system. Today added the extra bung to the exhaust to fit the wideband o2 sensor.

It's for my car. However, My car is my daily driver and it is about 2000 miles north of Miami. He's doing all the set-up work on his engine and car. When he's got everything ready I'll be taking vaction time from work to drive down to have it installed and the final tuning done on it. (I think he's scaming a stage 3 for himself, too)

yezeree,

That's what I thought. But you don't think he's going to do all that and then put your stock intake back on his car? No, if I were betting on Michael, there will be two Stage 3's, and none to soon. Michael, you must get a kick reading these posts!

[Earthworm]

It makes more sense to build 2 Stage 3 SVX's right off the bat. That way when a problem shows up with one it can be determined more easily if it is car related or design related.

[longassname]

Today we have pictures of the fuel pump install. We installed a Walbro 255 lph fuel pump in place of the factory 140 lph fuel pump in order to supply enough fuel for our demands.

The fuel pump is submerged in the fuel tank along with a whole bunch of fuel level sensors and brackets. There is an access panel behind the rear seats under the trunk carpeting.
http://www.ecutune.com/posts/fp1.jpg

After removing the access panel you can see the fuel hoses and the lid to the fuel tank used to access the electronics which are in the tank. Unlike the WRX our fuel pump and metering electronics are not attached to the lid but are on separate brackets inside of the tank. There are 3 brackets inside of the tank. 1 bracket has the fuel pump on it, the 2nd bracket has a fuel level meter and fuel pickup on it, and the 3rd has another fuel level meter and the jet pump (uses suction from the fuel return line to draw fuel from the pickup on the opposite side of the tank).
http://www.ecutune.com/posts/fp2.jpg

I didn't take any pictures inside of the tank. Here you can see the lid from the tank removed and the fuel pump assembly (the 2 metering assemblies remain in the tank). I have already switched the pump out at this point. The smaller silver pump now mounted in the assembly is the new 255lph pump. The larger fuel stained pump sitting next to the assembly is the old 140lph pump.
http://www.ecutune.com/posts/fp3.jpg
http://www.ecutune.com/posts/fp4.jpg

Since this fuel pump is intended for a WRX the wires are shorter than we need for the SVX. I didn't have any other wire handy so I clipped the ends off of the old wires and used the body of the old wires to extend the new wiring. I of course heat shrinked the connections to make sure no shorts could happen (positive metal contact touching negative metal contact). At this point some of you are probably wondering how come all these electrical connections can be submerged in the gas tank without shorting out. Remember not all liquids are the same. There's no water in gasoline; it's actually hydrocarbons and it isn't conductive enough to cause shorts.
http://www.ecutune.com/posts/fp5.jpg

With the new fuel pump the fuel pressure is raised 5 or 6 psi accross the board. I can adjust for this in the constant I will be adjusting for the new fuel injectors. This will have us running around 35 psi at idle and 48 psi at full load which will work nicely.

[EddieSVX]

Thank you! Just what I needed to start my day.

[Myxalplyx]

Michael,

You do realize that the fuel pump upgrade would be an interesting upgrade to those SVXers that are using a good extra does of nitrous right? Or even those folks like SVXtasy who's turbo'd who who'd like to go turbo. You could make a couple of extra bucks selling those already made up to be fitted to an SVX, while you are making this monster. Just a thought!

even a tiny amount of any sort of salt (NaCl is just one flavor) will make water somewhat conductive. most water has enough solutes in it to conduct electricity.

[poweredx2]

What in the world is this,from my understanding our stock pump already flow 255 lph so why the upgrade.When I first started playing with nos I called jeg and summit about a bigger pump,I was always told that the svx already have a 255lph pump.I may be wrong but that was the info I was given and also on a link about the good and bad about the svx.

[svxfiles]

Terry McLanes " The Subaru SVX FAQ " lists our factory pumps as flowing222lbs/hr, which is 37 gallons per hour or the 140 lph as Michael stated. Whatever you do you dont want to go lean at boost. Tom

[poweredx2]

That is correct,it was listed as gallons and not liters,so he must really plan on pushing over 400hp.I would have assumed the stock pump of being capable,but you know what happens when we assume,it makes an ass of you and me,I 'll be the ass this time for misunderstanding the info.

[Matthewmongan]

Yeah, as long as the stock fuel pump can hold pressure at full flow capacity, 140 liters/hr is enough capacity for at least 350 hp, it not 400 hp. It would be good to know the pressure rating of the OEM fuel pump at 140 liters/hr.

I'm not complaining. I didnt know about the fuel pump getting up-graded, but it's better safe then sorry. You should always leave a large safty margin. Never operate something above 75% of it's abilities. (Your car can run at 6000RPM, is it better to cruise at 2500, or Subaru have geared our cars to cruise highway speeds at 6000?)

your no longer feeding the factory injectors so in order to allow them to function at a higher flow level you need consistantly higher fuel pressure as well. Not just tapping a big fuel line and spraying it in via a pill/fogger. feeding 6 instead of 2.
phil

[Subafreak]

Ahh...gotcha;)

[svxfiles]

If any of you upgrade, or replace your fuel pump, BE VERY, VERY, CAREFUL!!!
The Subaru factory manuel says in what order to remove the three brackets, but not that they are held in place with a four fingered spring plate, or that they just lift out once the spring is gone.
Nor do they mention that one gallon of gasoline has the explosive power of SEVEN STICKS of DYNAMITE, (I'm sure some of you NAPA allready knew that).
Evan with the doors, the trunk, and the gas cap open,(I forgot the sunroof when I did mine:rolleyes: ) there is still a very strong smell of gas/air in the car during the job.
Park your car away from any smoking buddies that might stop by. I also posted NO SMOKING signs on the car. And make sure you disconnect the battery before you do anything else (except the windows+sunroof ).
So be carefull out there. Tom

I'll have Di put photos in a locker and post when she does.

Please read WARNING in two posts. Thanks, Tom

[longassname]

I'll have some pictures of the manifold to post tomorrow. I took them today but don't have the usb cord for the camera with me.

[svxfiles]

Warning, A thought occurred to me today. The hear shrink tubing that I used for splicing the in tank wires, Poly Vinyl is unstable when immersed in gasoline .
Wiskey Tango Foxtrot :mad:

The manufacturing rep said their coated conectors "should be OK" but did not say what they were made out of.
What I'll do now is remove the pump again, and replace the spliced wire with a fresh un-spliced wire, somehow:rolleyes: . I might have to crimp a new wire in the old clip connectors. Sorry, more later. Tom

[longassname]

We got the intake back now about half done. The top wrapper is welded in place and the mounting flange for the supercharger is tacked into place. We are stopping here on the fabrication of the manifold so that we can bolt the supercharger up to it and see EXACTLY how much vertical clearance we have and EXACTLY how far forward/backward to mount the supercharger so that the pulley lines up propperly. This will allow us to precut the mounting flange before it is assembled into the manifold, maximize the volume of the cavity the blower is blowing into and the opening size into the left and right sections, and make and use the same jig for the prototype that will be used on the production run.

The welds will of course be pollished out after construction is complete.

We've acquired our set of Nismo 740cc injectors which have become annoyingly difficult to source recently. We also have the new harness connectors necessary to replace the subaru plugs with in order to fit the Nismo injectors. We can't put them in and adjust the constant yet though because we have a defective wideband meter which we need to get replaced first.

Damn, 740cc. Thats a lot. What happened to the 555cc injectors? Not big enough? :)

oh god i have to go change my pants ..........this is great!!!! Keep up the good work and I can't wait to order my stage III

I know it's probably just the perspective but the intake looks wider now. It also looks like a large 6 legged spider :D

ok new idea to get more $$ for this project sell tickets to sleep near the car while getting worked on...1. more money coming in is always good...2. who else would protect the svx better then a fellow svx that wants to have that much power...3. i want to be first to sleep near it so i can be first to hear this baby scream and purr hmmm power (homer simpson voice)

Keep up the GREAT work man its coming along alot faster than i would have though

We got the wide band o2 meter functioning today. This allowed us to hook up the emulator to the ecu and verify our ability to adjust the constant used to calculate the base fuel injection quantity. This is the constant that we adjust to match the size of the fuel injectors. As usual :D our understanding of the sofware and calculations based on it were dead on. Actual measurements with the wideband 02 meter of effects on afr due to adjustments to the constant verify that the constant and it's mathmatical properties were correctly identified. With this verfied we can go ahead and make the sofware adjustments for the 740cc injectors and install them.

This by the way is the biggie. Lest it escape anyone's attention, today the last step necessary to unleash major horsepower from the svx was taken. The rest is just engine building, forced injection, the usual stuff the performance industry excells at. So drop the ballons and crank up the music the SVX is now officially in the same league as the skyline....if you build it we can tune it.

-Bill
The stock SVX fuel injectors flow 275cc/min. Stock Q45 fuel injectors flow 370cc. If my memory serves me correctly, the 300ZX TT injectors flow ~550cc.

Those Nismo 740cc injectors are an upgrade to Skyline R32 owners. I think that model came from the factory with similar injectors to the 300ZX TT.

Now from here things get fuzzy - I don't think the 740cc injectors were factory stock on the Skyline R33 & R34, but some specialized versions may have had them e.g. R34 V-Spec II Nur.

Either way, Nismo 740cc injectors are worth their weight in gold to Skyline R32 owners...

Now from here things get fuzzy - I don't think the 740cc injectors were factory stock on the Skyline R33 & R34, but some specialized versions may have had them e.g. R34 V-Spec II Nur.

Either way, Nismo 740cc injectors are worth their weight in gold to Skyline R32 owners...

Chike,
Good info! Guess I've still got the question of how Skyline injectors are going to fit in the SVX's fuelrail....which gets me to thinking that perhaps Michael and Co. are going to plumb in an entirely new fuel rail:eek:

Good point Bill.

I know 300ZX TT injectors are the largest I've ever heard which can fit in the factory SVX fuel rail. Since I used to own a '90 300ZX TT, I know that inorder to run HKS 720cc injectors, an upgraded fuel rail was needed - however, this upgraded fuel rail wasn't needed for the '95-'96 TT models (only '90 - '94).

My guess is that the fuel rail will need to be upgraded, but my knowledge of the SVX is not the greatest...

I'm sure the 740 cc/min injectors will work fine when the gas pedal is pressed to the floor, but from what I've read, its very difficult to make an engine idle or run smoothly at low fuel delivery situations with way oversized fuel injectors. From what I've ready, the old Legacy Turbo injectors are a direct fit onto the SVX fuel rail and flow at around 400-420 cc/min. If you install an adjustable fpr and set it to 55 psi base pressure, those injectors ought to be enough for 8 psi of boost. Someone at NASIOC also suggested that the new STi injectors may fit. Haven't checked that out yet though. Anyhow, you might have better luck tuning the motor with a smaller injector.

I tend to agree with you on this. Why so big?. It's very hard to get big injectors to function well at idle. the amount of fuel injected is the same amount as a NA engine, but the larger nozzel size, means that the 'on time' is almost cancelled out by the 'pick & release time' of the injector.

As the fuel pressure rises, as the boost increases, there is not a lot of extra fuel, needed to be added. We have seen No2 set ups adding the same amount of HP, through the std injectors, with added pressure.

Cost of the project can be a major factor in its up take, the lower the cost the more you sell.

[longassname]

Today's pictures are of the fuel rails and the installation of the 740cc Nismo injectors into the fuel rails. Our injectors, both the old and new, are what are called side feed injectors. As the name indicates, side feed injectors get their fuel feed from the side. This means they must seal at the top of the fuel rail and the bottome of the fuel rail and have open access in the fuel rail for the fuel to flow to the next injector and into the inlet ports on the side of each injector. You'll notice in the pictures that the new injectors are an exact fit. They are actually made by the same manufacturer that made the factory injectors. The old fuel injectors as pretty much all of the engine management hardware on our cars are labeled JECS. The Nismo fuel injectors are labeled UJ, for unisia jecs (JECS has merged with Unisia). There are differences in the design of the body of the injector between the top and bottom orings; however this does not apear to be any problem. The ports on the old injectors were towards the top side of the openings into the chambers the fuel injectors are held in while the ports on the new injectors are towards the bottom side. I can't speak for certain about why the change on the larger injectors but it seems likely to me that the height of the ports is made closer to the tip in order to reduce "latency." Latency is the measure of the time it takes between first energizing the injector and the actual release of fuel. Although the 740cc Nismo injectors can flow two and a half times the fuel as the old injectors their latencies are very similar. Back to the differences in the body of the injectors. Again, this is just a perception of mine and not known for certain, but it appears that they change the body design along with the port location in order to keep the open space inside of the cyllinders where the injectors are housed the same. I'm guessing they match the volume of the space around the injectors to the volume of the same length of fuel rail between the injectos so that there are no fluctuations in pressure accross the rails.

Maybe hes building it up for a stage 4 SVX here completly built engine that going for 800 horse, and the only reason hes not telling us is becasue he knows he would find SVXers constently trying to look at it and try to sleep in the car:D .

[Myetball]

I plugged some numbers into an online injector worksheet. Based on six injectors running max. 75% duty cycle, 0.60 brake specific fuel consumption, and 49psi in the rail. 720cc injectors would support up to about 550 crank hp. Assuming we're losing approximately 35% to the drivetrain that leaves 357 hp to the wheels.

Of course the numbers I used are generic but it sounds pretty close what I would expect. Then again, those are max figures. I wouldn't be surprised if the actual finished kit puts out over 400 crank hp.

[NikFu S.]

Crazy.

[longassname]

I installed the fuel rails with the 740cc injectors into our test vehicle thursday and did the preliminary tuning of the software to make it run. Yesterday and today I did the fine tuning and seem to have it down very nicely. Working backwards from the changes I made it appears the factory injectors are someting like 278cc's. Can't say exactly due to fuel pressure differences but they are definitely right around there somewhere. Factory idle was maintained without any problems.

Todays educational lecture:
The Nismo 740cc injectors are actually a little bit faster opening than the svx's factory injectors. Their flow rate is 2.65 times that of the factory injectors.These injectors are safely good for 550-600 hp depending on manifold pressure and assuming a bsfc of .6 and a duty of no more than 80%. The fuel pressure remains unaltered except that it will be increased by the same amount of boost. This is much better than running a higher fuel pressure for several reasons. First and most importantly we can accurately adjust fuel delivery with the ecu software. Second the fuel stream is more accurate so that a solid stream will hit the valve and be completely vaporized rather than creating a mist where more fuel is wasted. Third the fuel pump will last infinitely longer and be more dependable at typical oem pressures than at high pressure. These are the reasons oem's use the high 20's to mid 40's pressure range and they hold even truer for performance applications.

Summation of the fuel injector choice:
These fuel injectors will very accurately deliver fuel for stage III including at high rpms where the time available for fuel injection is short. They also have room to grow so once an engine is built to support higher levels of boost all that will be needed to have stage III put the power out is a smaller pulley.

[SVXRide]

Michael,
Very nice! How does the A/F look at tip in (okay, an old "carb" question:p ) - let's say "off idle up to 2.5k rpms"

p.s. how are you going to handle the "software" change to the stage 1 chip to provide the improved timing advance curve?

I got a chance to take some pictures of the injectors on the car and the new harness connectors. There was no need to cut the wires.

[deruvian]

Michael, I know that you haven't gotten around to dyno-tuning the stage 3 yet... But do you have any general ideas about where in the RPM band you are going to have the boost peak? Or the duration of the peak?

A question about the hardware, too... I've heard of a lot of supercharging systems being equipped with a bypass valve. This essentially leaves the engine running NA at times of low performance (i.e. idle). The bypass then closes when you step on the accelerator at a moderate or quick pace. Any plans to install one of these?

Just curious! :D

My former '00 SVT Lightning had one. I know that at the track some L owners who did long burnouts bouncing off the rev limiter would cause the ECU to keep that bypass valve open. Instead of doing a low 13 sec pass in the 1/4, they'd be handed a high 15 timeslip.

That bypass valve is kinda like a saftey mechanism which remains open if any detonation is detected in the engine...

We received a crate of superchargers from Whipple today. By the by we went with the Whipple 1600ax supercharger for our head unit for Stage III. This unit is highly efficient and will work very well both for the mid-boost planned for stock engines and high boost should it be used on an engine built to support it. With the 740cc injectors we've tuned the software for the Stage III package will be able to be used on engines built for high boost to yield very high output levels with only the change of the pulley.

[Phoenix_3737]

these are gonna be kickass when they are ready

[FlagstaffSVX]

Don't know if I should just email Michael but I'm sure that he's busy and someone else here can answer my questions for me.

Eventually, my (and everyone's) dream SVX would have a Stage III supercharger and a 6MT transmission to channel all that power. Realistically, the 6MT won't be affordable for years to come, if it ever gets "affordable" at all.

Should I try to 5MT my SVX now, then get SIII, THEN eventually upgrade to a 6MT after the 5MT eats chunks, or should I just keep the autobox, get the SIII, then just do the 6MT from the start?

Oh, and I doubt anyone else can answer this but I'll be visiting Pensacola FL February 5th but I can only get a week off from work. Is it concievable to install a SIII kit in 3-5 days?

Well if you can afford a stage III you should be able to afford a 6MT.:confused:


BTW: My 6MT is in the mail:D :D :D

[FlagstaffSVX]

Well... I figure, it's about 5.5k for the SC after exhaust modifications, and about the same for a 6MT. While I will have 5.5k by February, I won't have 11k to do both. :D

Maybe I should get the 6MT first... let's see, 4k plus clutch, pedals, mounts, labor, etc... I still think I'll go faster with Stage III though. :cool:

Oh, I know, I'll get the SIII first, then when I blow up the auto, I'll grab the 6MT, or if I still don't have the cash for that, at least 4.11's, yeah? Or crap, should I just spend a little to get the 5MT now and hope that I'll have enough for the SIII by the time February and my friends wedding rolls around? I'M MORE CONFUSED NOW THAN I WAS??? :confused: :rolleyes:

I really have the stage III software purring. Done the fuel and timing table rescaling and expanded the load range of both tables. Richened the fuel revision table like in stage 1 and thrown some more timing into the timing revision table like in stage 1v4. What can I say? It purs. It growls. I'm happy. I'll be putting a lot more miles on this code this week so we'll so if I decide I want to tinker with anything else but I'm thinking this might be the final revision till after the supercharger is running.

I'm supposed to be meeting up with the metal shop guy tomorrow night to go over some changes to the manifold with him and give the manifold back to him to work on.

OK, I asked these questions myself when I was setting things up with Mike for mine.

1) The Auto is accually built a little stronger then the Suby 5-speeds. If you can get past the heat issues that is.

2) Mike said once all the development is done, He should be able to do the install in a matter of days. Ruoghly 2 for install and 1 for fine tuning. However, I dont know if he is offering install as part of the deal for everyone. He is doing mine because I fronted the money so he had some working cash. I paid him for mine back in late August.

[FlagstaffSVX]

Awesome. That settles it, I'd rather be Supercharged with the stock autobox than N/A with a 5 or 6MT.

Next question, can a 21-year-old rent a car? If this all goes right, I might need to drop the car off with Michael then get back up to Pensacola for the wedding although if it's only going to take two days to install, I'd probably have plenty of time.

Oh, and I can't believe I forgot that Michael didn't have to install it. Might just end up doing it myself then... or my mechanic, after I get lost. :)

And don't worry Earthworm, I haven't given up on joining the MT club. Dayle's auto's might be fast in the straights, but I want a human brain controlling the shift points instead of our crappy TCU for the turns. :D

It also prevents all the smoking of clutches possible with the MT, too.:D

You're gonna try and put all that power through the front tires?!?:eek: I think that'll be tough to make a set of front tires last... AND not get overcome with torque steer.

This has been my hang up as well... wether to build the auto to take supercharging, or go MT. I fear most 5 speeds may end up getting trashed but the 6 isn't THAT much stronger and all the final gear ratios aren't as good for highway cruising as I'd like (in basically all MT's available).:(

[Matthewmongan]

how is the belt and pulley system going to be run?

[longassname]

Met with the metal shop guy today and gave him the manifold back to work on. When we get it back we should be able to bolt the whipple supercharger up to it. He'll also be making the beginings of the adaptor plate for the throttle body so we'll be able to start lining stuff up directly on it and mark it up. The space left to squeeze the/a alternator back into is tight but we'll work it out.

Oh, and no I dont do nuetral drops. I did one once a long time ago in a different car and I didnt like the loud bang that comes from the tranny. If I break traction with pure accelaration it's one thing but that hard slam will break even the strongest of trannies.
It's just the only way I can think of that would possibly spin both tires in dry conditions. Wet pavement I have broken both tires loose.

Di and I drove around the other night with the select moniter hooked up to watch the F/R power split. Most of the time it was around 77%, at wide open throttle it was 50/50, in park it said 95%. For years the Subaru Reps said 90/10, but at idle, in park it says 95%.

I think that the moniter measures the duty cycle that is sent to the C sol. so the 95% would be full voltage to the solenoid fully opening it , on your model this is fully disengaged. I got a VTD box which works the oppersit way, 95% on it, is fully engaged.

The STi trannies are 50/50 base, no?

Anyhoo, back on topic...

How's the chip set up for Stage III? I don't think I've seen anything about that. Will it have the NOS code, the 87 octane code, or something completely new in the second slot?

The fuel and timing tables will have to be different for stage III. The power from the supercharger will not be as linear as that of the nitrous. Also, I'm guessing that it will not be set up to run on 87 octane... especially since premium was the desired fuel in stock trim, we'll most definately need premium to help stave off knock with the additional pressure and heat created by forced induction... as well as the timing being retarded.:cool:

[ThetaReactor]

Yes, I'm quite aware that it'll take a completely new config to handle the boost. I'm just wondering what kinds of alternate option it might offer.

[Pure_Insanity8]

What do you mean?

[ThetaReactor]

I mean that stage I has Performance + 87 octane mode, stage II has Performance + nitrous mode, stage III has boost + ????...

[alex_umn]

Maybe there could be a clutch on the supercharger drive pulley that would be tied to the trigger for 87 octane code? So, flip a switch, and then you can run cheap gas and have the supercharger turned off. That would be sweet!

Wonder what else could be put on such a switch...maybe electric control of Koni strut inserts? :D

[Pure_Insanity8]

Yeah, that'd be pretty crazy!;)

I'm going to bet that it'll only be one set of tables since allowing the supercharging to be turned off won't be in the picture (at least not currently), and nitrous with the blower would be pushin; it for now. Also, a lower octane set wouldn't make much sense since it would kinda be like shooting for less power due to not allowing the timing to be as advanced as possible for maximum power. I'm just making a guess... but I'm pretty sure that is what it will initially be.

can't rush perfection ...heck i think he's almost done once that manifold gets back .....he's already upgraded the fuel system and has definite certainy of integrating with the ECU for the increased air flow.

I sent an e-mail to Mike earlier this week asking the same questions (status & timeframe). He said he's still waiting to get the manifold back and there are still some more modds to be done to the fuel system, the altenator mounting & belt system needs to be determined, and then the ECU adjustments. So completion is still a little ways off.

I'm just hoping I can get mine before X-mas. I'll be a great present from me to me.:D

Information contained within this thread if you read through it. Initially was going to use a roots style, now it is set on a screw type (Whipple). Hopefully, high three hundreds, close to four hundred at the crank as far as horse power gains go. I'm thinking that it will be at least significantly over three hundred if boost has to be kept lower than planned.

Whatever the case is, this should come out pretty well with Michael's competent mind and hands behind the wheel of this project.:)

[svxwill]

with at least 50% to 60% more power than stock EG33, will the stock suspension and brake hold up?

Just depends on how you use that extra power.:)

Would be a good idea to upgrade both, however... even without the supercharger. At least in my opinion. Better braking and handling are always a plus... as long as you can afford it.

[svxwill]

:) i feel the same, that's why i love the svx. my old mustang had power but no control(till my mod it). why go fast if you can only go straight unless you are a drag racer and all u see is 1/4mil.

Agreed. Always a good idea to upgrade the brakes and suspension whether you're adding a S/C or not.

However, the stock components will do just fine if the car is driven in a civilized manner. Even 1/4 mile racing will be fine...

I remember Harry (newsvx) telling me a story at his place about a guy with an upgraded S/C 5.0 Mustang who was racing at Summit Point. He was still on his stock brakes, and after 3-4 laps his stock system just over-heated and failed. Won't go into details but the guy died instantly in the wreck... :(

As far as stock parts holding together with increased HP is concerned, my guess is that the axles are going to go somewhere between 350 and 400 HP (at the flywheel).

Huck,
Good question! I was basing it on the stock engine being rated at 230 HP at the flywheel and the axles being designed with a 1.5 - 2.0 factor of safety. I threw in the fact that Poweredx2 (I think) has posted that he's snapped at least 2 axles running a 150 shot at the strip.

Good point Bill. Poweredx2 did snap his axles on his way to that 13.32 run in the 1/4...

-Chike

[huck369]

I don't think that the HP is the real killer, it's when you do a clutch dump, and shock load the drivetrain that it's looking for a place to break.....I'd rather break an axle once in a while, as opposed to breaking a tranny....(actually, I'd rather not break anything:D )....

[Chiketkd]

I think in poweredx2's case it's more a surge of power from the NO2 rather than a clutch dump - as he still has a 4EAT. However, he also used slicks when he broke his axles...

[TomsSVX]

i asked before but ill ask again, since there is much similarity between the 05 STI and our svx in the lines of wheels brakes etc, will we be able to swap the STI axles so we can handle more power than our stock units or are they weaker/don't fit/same ones?

[mikecg]

Aren't the FWD SVX axles heavier than the AWD? And could the AWD guys swop out their axles for the FWD ones to handle more power?

[TomsSVX]

sure, the front axles that is, what about the rears? aren't they different?anyway, i would imagine that the STI axles can hold a good amount of power. Also, the fwd are not as heavy as they should be, cuz mine are less than a year old and seem to be crapping the bucket already. Thats why i am intirested in STI axles, although buy 6 of them is gonna put a hurt on my wallet.


BTW mike are u comming to the Jersey Shore meet on the 18th? hope to see u there.

It was a combination of many things - probably brake fluid boiling coupled with super hot brakes - but at the end of the long straight on Summit there are three run-off areas (one behind the other) to slow a car down if it went off the track. He went through all three and his car was a mangled mess when they finally got to him. He must have been doing over 120mph when he left the track...

My younger brother, Michael Krynock, did 160 mph into hay bales, on a motorcycle while racing at some pro track, I think in his now home state of CA.

[TomsSVX]

so moving on from the silliness and talk about crashing, is there any way for us to find stronger than stock axles? i know they are the most stout and what not, but is there a way for us to upgrade. I realize that the STI axles are a different tyupe but i am sure they can hold more power than ours, so finally, does anyone know if they will fit?

[SVXer95]

Why change from stock axles? I, personally, would rather have my axles break than my diff. Just a personal opinion.....

You have to remember that something always has to give. Whether it be tires, cvs, axle shafts, or the transmission, something will break when you increase power. Axles are cheap and easy enough. Unless, that is, you are planning on upgrading everything along with them....

[THAWA]

Originally posted by svxsubaru1

WRX sedans have a wider track in the rear than other new gen subarus, so maybe, but again it depends on how close WRX axles are to SVX axles.

[mbtoloczko]

Originally posted by svxsubaru1

The SVX axles are already stronger than the OEM WRX axles, so why bother looking for upgraded WRX axles? I really doubt that anyone with an AWD SVX is going to break an axle due to HP.

What about pulleys? (http://www.speedyperformanceparts.com/unorthodox-racing_su_svx_performance-pulleys_z.html)

Yes I know they are expensive, but for some hp and something that might be more reliable it just might be worth it. Then again the stock ones can be as good as these, I don't know. Sorry if I sound like such a tool.

None, the stock SVX 4EAT should be ok with enough cooling. It held up with stage II which has 513ft lbs @ all 4 wheels. And its used in the 1000hp ESX drag WRX.

That value is incorrect. 513 ft-lbs was calculated assuming the tranny was in 4th gear during the dyno run, but it was not. The real torque value from LAN's stage II trials is closer to 320 ft-lbs. Still impressive but just trying to keep the facts straight.

As far as the 4eat goes, mechanically, it is plenty strong for major HP, but it needs mods to keep from overheating.

Actually the 513 ft lbs is correct because it was an at the wheel measurement.........i think it was 518 though, i'm not sure. Anyway the inaccuracy was that it was an at the wheel measurement so it wasn't true measurement of what the engine was putting out but what was being put the the wheels after being multiplied by the torque converter of the automatic transmission. The measurements spanned both 3rd and 4th gear. All this talk about axles is a little premature. If we start snapping axles then we will look at it. Good axles can be made we don't have to worry about what other factory axles can be swapped for should the need arise.

More importantly, all this axle talk is just because there hasn't been any new news posted on the project in a while...I spoke with the metal shop once again and now I'm being told we should get the manifold back monday night. Unfortunately it will be in an even less complete state than I had previously expected. None the less we will be able to mount the supercharger to it and will have the blank flange for the throttle body. This will allow us to line up the pulley for the supercharger with the crank pulley so we can mark the mounting bolt holes for the metal shop. It will also allow us to see what space we have to work with for fitting the/a alternator back on the engine. It will also allow us to start fitting the throttle body to the inlet flange and figure out how we are going to relocate the factory idle air bypass valve as well as the bypass valve for the supercharger.

Unfortunately all those hurricanes that rolled through Florida did a lot of comercial propperty damage which has resulting in flooding the metal shops with huge contracts. As tight as I am with one of the main guys at the metal shop I'm using our project still gets left on the sidelines while they rebuild fort lauderdale international airport. I've about resigned myself to the metal work not being done before I move (fyi we are relocating to tampa fl in the begining of january). We can't go to a smaller shop that isn't flooded because they just don't have the equipment to do some of what needs to be done but if it's not done before then it will at least be in a state a smaller shop can complete. We will then send them the complete manifold along with our jig so they can make a few copies after their work load decreases.

Oh the joys of prototyping.

The 518 ft-lbs is not the value measured at the axles either. Its way too low for an axle value. If the stock EG33 puts out 224 ft-lbs at the engine, then at the axles, the torque in 3rd gear would be 224*1*3.54 = 796 ft-lbs, not including drivetrain losses. If 30% losses are assumed, then the value drops to 557 ft-lbs. The TC does maybe a few percent torque multiplication at 4400 rpm, so 557*1.02 = 568 ft-lbs. This is higher than 518 ft-lb value with the engine breathing NOS.

You mean what the actual supercharger looks like, right?

Although not exactly what it would be like for the EG33... here is a kit for a Cobra: http://www.whipplesuperchargers.com/product.asp?ProdID=1204

and a small block: http://www.whipplesuperchargers.com/product.asp?ProdID=1172

That should give you a basic idea of what will sit atop the engine under the hoods of those of us lucky enough to afford Michael's highly anticipated kit.:)


The time the metal shop is taking makes more sense now, Michael. Understandable, they gotta take the big accounts when they can, and have to make them a priority so they can satify the customer and get paid. It is also great how you instill a sense that "if we need to beef something up later, we can and will.":)

[longassname]

Ya me too. (In both the sense that I want to complete the project and want a stage III myself.) On a positive note thanks to the delay I won't have to waste a set of stage III fender badges when i paint my car later this month. I think I may post a thread showing that too. I'm sure no one else will be tempted to spray their own car but it should be entertaining none the less.

Now back to Stage III talk. I'm going to talk to the metal shop guy later today and tell him I'm going to go up there tomorrow to pick up the manifold come hell or high water. So if they don't have at least what they said they have done done they will have tomorrow to get it done before I show up. Considering how little work they have been able to do on the manifold since they got their big contract I'm not too anxious to give it back to them. I'm going to go ahead and mount the supercharger and start fitting the alternator and throttle body. That will probably take us trough relocating to Tampa at which time I'll see if I can't find a large metal shop there that can give our work more attention.

I thought that you were going to turbocharge the SVX.

Is it going to be a Hybrid?
