I'm currently running the 3.5 pulley and peaking at 10 psi with no kr. Is it worth it to drop to a 3.4 and what would be the psi increase be for such a small drop in sizes?
 


maybe 1 pound of boost or so. if youre not knocking then try it out and see where it goes.

in all technical senses you would probably gain more from added timing and not more boost.
 
I would try the 3.4 it is worth a shot..........if you have any KR, then go back to the 3.5 and sell the 3.4...........my .02
