It's looks like your metal shop guy will be responsible for someone's 'nuts' being in a knot!

WOW... thats really interesting... it has a water to air intercooler??? or is that just a really small air to air?... what crappy picture quality

hehe, add water injection or maybe even meth.. and you'd be making crazy hp and decent boost numbers

looks like it will be a monster eninge!!!

what type of sc, how much +hp?

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.

thanks! just 2 lazy to read all the threads.

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.

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).

Why would you think that?..... there are people running 400+ hp in thier WRXes through stock Subaru WRX axles....

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...

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 )....

[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...

Chike,
So you'll be upgrading your axles soon (aren't slicks in your "winter upgrades" list )
