I'm new to forced induction and want to get everything close to right the first time. Stock bottom end and looking for 500rwhp if possible. What blower pulley should I get from SDCE?

SCDE 8 rib w/7.25 crank pulley
P-1sc-1
LS6 intake
PP LS6style heads between 10.3 10.4 CR
TR220 114 cam
stock manifolds w/ high flow cats
RPM max 6800

Which pulley do you recommend and how much HP will it make?
Also, is it worth the $$ going to FMIC instead of the ATI duel 3" coolers?
Thanks.

4" with a D-1SC should be enough for 500rwhp so i would say 3.85" on the P-1SC.

A 3.4 got me 518 rwhp with stock cam and redline.

I would say with your size of crank pulley and mods along with elevation. I would go with a 3.7.
I see a good 9 psi with a bit larger crank pulley 7-5/8, and a much higher elevation.

Which made me 540.

Remember every car will be different. You might have to play with the pulley sizes. Right now I am doing a cam with a 3.7 pulley. Hoping for 9-10 pounds. If I don't get 9-10 then I'll go down in pulley sizes slowly until I get there.
