What kind of power gains am i looking at with the 8lbs kit going from a dc 4-1 ??

 

Hard to say exactly. But the 4-1 is THE worst route you can take with a SC'd car. I mean, its probably better than stock, but a lot better can be done. I would say at 8 PSI you'd be looking at between a 8-14 HP maximum gain.

Talk to the people here at Hostboard------>Car's, Hotrods, Trucks------>Forced Induction Integras. That is the prime SC forum with people who are more apt to accuratly answer your question.

 

Can't say about 8psi, but @6psi, I made over 24whp w/the 2.5" Kami + high flow cat, over stock.
