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! --------------------  QUOTE (Galcobar @ Oct 15, 2008 - 2:44 AM)  You want power but have no money. That's a problem. Cheap. Reliable. Fast. Pick two. |

is a small mod done to the wastegate, you add a spring to increase the tension, so it needs more pressure to open the wastegate.
I'll try to find a link for it. of course that was with a WRC turbo ( steel wheel ) a non WRC turbo ( ceramic ) wouldn't hold for too long that kind of stress. --------------------  |
