Just curious if anyone has run a smaller pulley on their P1SC and what boost/#'s you were making? Friend of mine is claiming he is making 575 rwhp with a 2.5" reichard racing pulley. built 2v block (8:5:1) with blower cams, longtubes, etc.
thoughts?
If that's actually true I can pick up a used P1sc pretty cheap that just had oil changed.
