PowerPipe Exhaust for slant/6

your really gonna need some cam and compression (10:1+) to get 250hp... i should be around 210 maybe more if im lucky... will see...

Naw...I was usin that for reference as the absolute MAX it would put out(maybe includin a small shot of spray). I am trying for 1 HP per cube. I know it will be tough....but I can try, right?
