but max boost on that blower plus say a 150 shot would be over 600 i hope. And im assuming we are talking about hp at the crank. I was making 500 at the wheels wiiht the stock block and 11 psi.
Damn, how fast do you want to go? 18 psi will give you low 10s on a properly set up car---the 150 shot on top of that you would easily be in the 9s.
Go with a cobra (Kellogg) crank, some good rods and a JE, CP, or similar piston. Spend a little more and build once--especially when you consider your future plans (FI + N20).
