ECUTune Stage III twin screw supercharger sign up - Page 16

Duckie · #**226** 08-29-2005, 05:03 PM

Well the ecutune site is down and a hurricane hit florida not too long ago... I am also anxious for details because my current living situation is up in the air so I am anxious to get the product and install it. Not to mention hopefully hook the site up with some video and stats of my car post S/C setup.

Here's hoping LAN is alright!

Thanks I'm fine. Power has been out at the corporate office since katrina ran through miami so our server has been awol. I've mostly been kept busy with other stuff, stage 2v4, designing PCB's for other products people have been whining for, administrative stuff, etc but I got back to stage 3 fab yesterday and did some manifold welding. I'll take the camera with me today now that I can post pictures again.

I have some pics of the #1 manifold sections. I welded the bottoms on yesterday and today and ground them out. The piece i did today has the egr on it and man did I have to lay some heat down. I really need to motor through that weld but the 50 amp breaker the welder is on kept popping. What a mission. I'm gong to have to step the breaker up tomorow so I can make some real progress.

I have some more pictures.

I cut, welded in, and ground out the side section for the passenger side of the #1 manifold. Unlike the drivers side on the passenger side the bottom and side sections are seperate pieces that have to be welded together.

I then machined the bolt tubes which will hold the supercharger to the manifold. Here you can see the 1" round stock in the lathe and the drill bit for the bolt hole in the tail stock.

Here I've done the external facing and parted this one from the stock.

Here you can see one of the pieces and the 8mm bolt counterbore I use to machine the opening for the bolt head and washer.

Here are the 5 tubes for this manifold sitting on the flange so you can see what they look like and understand what they are for.

Here is a level profile shot so you can see how they compare to the surface of the manifold top and again to give you some idea of the difference between the angle perpendicular to the centerline of the engine and the surface of the manifold.

Mike,
So, are you going to have a slightly "humped" center section that the compressed air will flow into and then out to the runners via the triangular cut outs? Any concern regarding the turbulent/potentially unbalanced flow (note: I'm saying "potentially" as I recognize you do have a volume that the s/c will be filling adjacent to the runners) to the cylinders you might end up with as a result of the "hard right turn" and the the triangular cut out? It looks like the "line of sight" cross section for the flow to the front two cylinders could be as little as 1/2 of that for the back two cylinders.

Just read the thread.

This is quite the undertaking for a R&D staff of one man.

Work appears to be top notch, though.

Looks awsome Mike!! Great work so far, you have done a great job on helping the SVX aftermarket community!! You will be receiving a PM within the hour

Today I machined the bolt tubes for the rest of the manifolds.

Subafreak · #**236** 09-05-2005, 10:41 AM

Great pics man, I've been wondering what it was gonna look like on the inside and where the S/C was placed with the rest of the motor.

I imagine even flow won't be a huge issue as you will be filling the manifold with more air than one cylinder can take in all at once anyway. The angle of the manifold inlets is not of a concern. Pull the S/C off a 3.8 Buick someday and take a look at the air delivery for that motor, very small.

*drools in hopes of an update/estimated completion*

longassname · #**238** 09-10-2005, 12:44 AM

Stop drooling, lol.

I have pics of the welding I did today. Today I welded the bolt tubes to the discharge flanges.

This first picture shows one of the discharge flanges with the bolt tubes just welded on and the bolts used to align and fix the tubes during welding still in. The bolts used for this are not the same as the bolts used to mount the supercharger but are the exact same size as the hole so that the tubes are perfectly lined up.

And here is all 6 of them. The 6th one in case anyone is wondering is for redoing the original prototype to the production run specs. It will be going back on my car.

Faster than a TIG welder.......more powerful that a 6-71 blower....able to machine 7075-T6 with his eyes closed.....he's SUPERLAN!
