i have a motor that im going to put a blower on and i'd like to see around 15psi of boost. it's a 363ci motor, 8.5:1 CR and i have a paxton novi 2000. right now it has a 7" crank pulley and what looks like a 3.75" pulley on the blower, both pulleys are stock and still in the box.
does anyone have any suggestions on what i should change the blower pulley to? i know that we wont know for sure what it's putting out until she goes on the dyno for a tune and it's safe to shoot up the RPMs.
do you think i should drop down to a 3.00" pulley or a 3.25"?
