Which pulley?
Which pulley will put 10psi on my combo?
A@A P1sc kit, LS7 blade maf, LS7 tb, fast 92, stock 99 LS1 heads/cam and shortblock.
It goes to be tuned in a week. Time enough to order a different pulley if needed. 3.85" currently installed.

Agreed. Use of cams and other components will affect the boost.
For reference, I ran a 3.6 pulley for 10psi and am currently using the 3.4 pulley at 12psi. Car is an 01Z with a stock cube forged 346, oem heads, mild blower cam, and longtubes.

P1 is rated at 1200cfm
SI is rated at 1150cfm
Can't just compare pulley size on different applications.
