I have a 2004 Dodge SRT-4 with a 3" downpipe, 2.5" stage 2 exhaust, 3.5" front mount intercooler, and a Mopar long ram cold air intake.. How much wheel horsepower and torque and crank horse power and torque will i have with that dont to it ? I have been wondering cause I have beaten WRX's, older M3's, and STI from a roll, Mustangs, bmw 330ci twin turbo, audi s4... I mean i know my car is fast but damn, how fast !!! i got stock turbo and pcm running 15 lbs of boost.... Any ideas ? i have no time to dyno it, but i heard they are underatted at 230hp, they actually have 275 hp stock to the crank 230 to the wheels...
Since you really haven't increase boost with stated mods, I'd guess you would have roughly 260whp. You are probably winning because the mods you do help alot increasing torque and horsepower under the peak.
The 2003s were underrated at 215 crank horsepower. Alot of them were dynoing around 230whp. The 2004+s probably weren't as overrated at the first year SRT4.
