blower and crank pulleys

[5literstallion]

ive got a single belt novi 1000 and i am currently seeing about 4.5-5 psi on my car with heads cam etc. i have the stock blower pulley and the stock crank pulley, im looking to get about 9-12 psi out of it. what combination of crank and blower pulleys or just blower or just crank pulleys can i use to acheive this kind of boost without a powerpipe? is there a formula where i can find what kind of boost i can make? also about crank pullies, is asp the only one who makes single belt crank pulleys? and if i were to get an f-150 pulley what year would it be off of? thanks guys

Boost can really fluctuate from combo to combo. For what you are looking for, the f-150 pulley (just about any late 80's early 90's model with a V8) and One of Ian's 2.75" blower pulleys should put you in the range you are looking for.

has anyone run the 2.75 and f-150 crank pulley setup on a single belt novi 1000? if so how many psi have you seen at about 6000 rpm? with powerpipe or without? what about the 8 inch crank pulley by itself, how much with the stock blower pulley would i make? also, anyone with the 2.75 and f-50 combo, would i experience belt slip after buying a tighter belt?
