-3.46 Diff..
-Pulleys

2001 Audi S4
Stock Turbo's
Chipped using giac chip
Custom Exhaust
Manual

 

S4 for sure!
even with an M3, BMW still behind!

 

the m3 will be faster if its supercharged...sorry dude, thats going to put it around 400hp with about 400 less lbs to carry around.

 

with KO4's,camshaft, etc... S4 can do so... but with both stock... who would win? S4 or M3 ?

 

No one has answered his question yet, haha.

It depends. I'd say the Bimmer will be faster. An S4 is very quick when chipped, but it's not a *beast.* Those 330ci put down 225 stock. I'm guessing that the twin screw gave him about 100hp. So, he's probably pushing about 325-350 with the exhaust and everything. The S4 should be putting down about 320-330 with the chip + exhaust. The S4 will probably have a little more torque to play with than the Bimmer. Off the line, the S4 will rip the 330ci a new one if it launches properly. I doubt it would stay ahead, though. The Bimmer has 3.46 gears, too, which really doesn't help the S4s chances.

So, it's tough to tell. I don't know how much power those 330ci's typically put down when they are supercharged, but since it's a coupe, and significantly lighter than the Audi, it'll probably win. It probably won't be an "ownage" victory for either car, though, unless the 330 is pushing more than 350 horsepower. Luckily it's not an M3. A supercharged E36/E46 M3 would joke any S4 unless it's running K04s with fueling.

 

I think the BMW would likely be quicker though it would be close and dependent upon launch and shifting and such. BMW - particularly supercharged - are not at all slow.
