awesome numbers and nice ride. I predict that motor will eat itself after a few passes at the dragstrip....better get some octane in her before the geyser shoots out of the overflow

I was referring to 18psi at the track on 93 + meth. Track is a **** ton more load vs the dyno. 800+ rwhp + all that weight and any detonation with stock heads will probably lift a head. Awesome setup and numbers but I would play it safe with some more octane. Just my 2 cents and no hating
