Thanks,
I wonder why desktop dyno wont let you change intake or exhaust when you select forced induction. I guess their believe is if the air is getting forced in it has to go in and out more according to the boost than the manifolds. Probably real world situations are different. lol. I only have a so ho sd conversion stock manifolds with a 6 psi boost at 6K but the engine runs out of power way before then. I am a firm believer in the highest average torque for the street. Most of the stuff I've read say that the v style manifolds are soft on the bottom end and peak somewhere between 4k-7k. I just feel that's all wrong for the street imho

p.s. I have to ask this. Why Katrina and Rita?
