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....

http://www.mr2oc.com/showthread.php?t=2714...horsepower+gain

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!

You want power but have no money. That's a problem.

Cheap. Reliable. Fast. Pick two.

hmm... 300+ is quite wishful, i think those levels are above fuel cut level with some kind of water injection safeguard,

these guys are struggling to push past 250 hp atw which in itself is an increase probably max boost 17psi before cut since factory is just 250 at the engine
