I'd like to see a link or actual proof. I can see the getting a 15HP when you start getting into the higher hp levels and the 2.25 isn't giving you enough flow. |
Re: Dia of pipe on boosted Engines.
Wouldnt it be simpler to just chk with no pipe and then with pipe whatever the dia and you will see the gains or looses.
If you look at the bikes and cars in the Dyno Shoot outs and the Salt flats they just dump right out the turbo no pipes. Do you really think they would do that if they where bothered with velocity in the pipe or if they could get more power by runing a pipe. ? One thing I have noticed after studying hundreds of comapny fited turbos. Is that more than the dia of your complete pipe. But rather the first 6-12" of piping that really matter. Its as if the air is very turbulent when it exits the turbo and needs place to go laminar. Im making arround 80% more power than stock at 10 PSI with my 1" Exhaust. WOnder what will happen when I dump it. Or go to 2" |
