Wondering on what your approach will be...



.
the pulleys been in the box for awhile....i think it was either 6 or 8 psi on the 468 pontiac i bought it all off of. i figured those pulleys might only give 4-6 on this one. i will start off low, might even start with pump gas
since i have stuff for it. the more i read the comments about a butker 535 making 800+ hp and over 800tq and living forever at that rate has me throttling back a smidge on where to stop at. im not sure what kinda boost that combo was making ....but it seems like those results shoukd be easy to duplicate.
