Maximum Boost

[Player01]

So, I am totally new to Audi's. I drive a Mustang GT with a significant number of suspension mods. While I love the Muscle Car sound. Id be willing to trade it for a Tubro Blowoff. So, I want to know, if I upgrade the turbo and piping, what kind of boost can these cars take? Is A4 or S4 going to be the better car, or the A6? I want a track car, not a drag or rally car. I really like WRX's but I think I'd rather have an Audi. Tell me, what is the max PSI I can run on this thing? and what kind of power will I be making with that?

welcome to the forums

while i cant really help with turbo pressures etc, i can tell you that the S4 runs a naturally aspirated 4.2 V8. the A4 (and A6 i think) is available with a 1.8T engine. saloons/avants were available in 163, 180 and 190 bhp i think. (the a4 cab only came in 163 bhp)

remapped, a 163 engine will produce just shy of 200bhp without any other mods.

the A4 b7 model (with the radiator grille that extends "through" the bumper rather than a bit above and below) is available with a 2.0T FSI engine. standard options are 200 and 220 bhp i think. i think the 200bhp variants can be remapped to 240bhp (again without any other mods)
