Pulley configuration for 20psi on an F1A Hi,
I am running an F1A Procharger on my forged 347 and currently it the standard 8 rib 7.65" crank pulley and the pulley on the F1A Procharger is the largest one at 5.25", for the lowest boost possible.
Well I am changing my setup and looking for the right pulley for my procharger to make roughly 20psi of boost.
Does anyone have any recommendations on this?
Thanks

With a 347 and depending on the rpm your turning you don't have to max out the blower to get 20 psi.
A 4.00" pulley and 6800 engine rpm blower will be spinning 70227 rpm max is 72000.
A 4.25" pulley and 6800 engine rpm blower will be spinning 66096 rpm.
I am selling a 4.00" and 4.25 pulley that i sent to have carbinite coated, this keeps the belt from slipping.
