How Much Boost PSI
Just a quickee. I have a 15% SC Pulley and a 3% Crank Pulley on my car. What sort of Boost am I looking at?

bear in mind the boost will depend on altitude, amb temp and humidity

I live 4600ft above sea level and I get around 12 PSI boost at WOT with a 17% pulley.

I live in an area of very high heat (avg. 33 deg C) and high humidity (avg.97%) - and have a max boost of 15psi (@6.8krpm - 3&4 gear) with 17% pulley.
