I havn't gotten my car back from the rebuild yet but i was just wondering with the howell bottom end kit along with port matched head and manifold, valve job with new guides, 440 injectors, S AFC, and the SFMU.
My pistons I got .020 bore and 8.5:1 compression pistons.

Thanks

15psi?

AFTER the break in period (I would drive for 1000 miles under no boost) you can run 15 psi safely. If you want more you are going to need an MSD and slow down the timing some. I plan on running 15psi daily when i am stage 3.
