"Sure you can run 15 PSi on a stock engine." I can't tell if that's sarcasm. As long as I kept it rich and stayed away from detonation, could I run 15psi? I understand those other things would make it safer but is it useable for a stock engine?
Yeah I have an HEI, I posted that on the supercharger thread in my list of parts just today.
But was I wrong about the air/fuel ratio? isn't <14.7 rich? isn't 12ish pretty rich at W.O.T.?
And what would I do to fix my extreme richness at idle? Do jets affect mixture at idle?
69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
