i have a question about the boost. how much hp do u get per psi of boost on a stock series 1. and how much would you get with a pulley wit about 10 psi :?:

There'* no way to answer your question. Too many variables.

Boost pressure is power NOT USED. 15psi would do you no good if you can't flow it.

The proper formula is the most boost you can run and still achieve max timing.

I believe if you check the Intense site, they list things in drops of pulley sizes for "typically expected" numbers. Then you would have to convert that over to yours. While the S1 and S2 are quite different.. you can probably use it as a feeler gauge on what might be.
