3" downpipe power increase?, about how much? Options

[easternpiro1]

Hi guys, Ive been wondering how much HP increase do you get when you add a 3" downpipe to your turbo setup? ive been told in the past at least 10hp, but before making a thread i decided to do some searching....

and now I have a headache...

on our 3s its obvious that a wider diameter exhaust makes room for more power, but ABOUT how much typically?

I actually read 98% of that thread, and while VERY informative, i didnt get a question answered after all the searching.

anybody know the answer?


cheers!

250AWHP at 17 psi is not the same as 17 psi on a Front wheel HP, the drivetrain loss is a big factor here, 3rd gen 3s make right around 300 HP at 18 psi ( 2WD )

whats the specs on the engine/turbo/intercooler/management on that????

those are pretty good numbers, but that trailing off after 6k can be fixed (potentially meaning a higher max hp can be achieved)
