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! -------------------- |

stock engine, stock ECU, no fuel control, water injection, stock WTA intercooler, 3 inch exhaust all the way. if there was any fuel correction it would have yield better number, but my point was to show how much power is consumed by the AWD trans, a ST205 has the same amount of power with the same mods, but yet the numer is considerably lower at the wheel, because of drivetrain loss.
I have a very similar set up at the car on that dyno chart, haven't dyno yet as I haven't done anything to my setup that would require it, once I get my fuel management software for the HKS F con, then I'll go to the dyno for some tuning, I expect at least 15 whp extra because of the fuel corrections and cam degree adjustments. -------------------- ![]() |
