My buddy Mike copied my exact
build recipe, minus the nitrous and 3.33 gears. He went 10.31 @ 137 yesterday, on 19" drag radials. This was his first visit to a dragstrip, ever. Started the day by running 12s. It was a track rental day, so he got plenty of seat time and practice, and some coaching. His runs were on 93 octane, he drove it to the track and drove it back home. Around 850 rwhp. Mine makes 851 rwhp on Paxton + 93 octane, no nitrous.
If I were to do it all over again, I'd skip the Paxton + stock engine. That combo was a ****. I'd go twin turbos on a stock engine. They will hit harder and perform better, even if only 700 rwhp. The Paxton is only good on a built engine, where it can spin to its happy rpm range. That is around 11-12 psi boost, and 800-900 rwhp. Anything less, and the Paxton feels laggy and has pretty weak throttle response. People may think their Paxton stock engine car feels fast, but it is a HUGE difference when you turn the boost up on a built engine.
I went the nitrous route because I'm at the upper limits of my 2-bar MAP sensor already, so I can't add boost. The Novi2000 is maxed out as it sits. I'd have to invest another $5-6K into a stand-alone ECM if I wanted to increase the boost (via twin turbo, etc...), but then I'd lose my OBD2 state inspection possibility. My car passed the Texas inspection last week, btw. I can also drive it to work on 93 octane, even take a road trip in it, if I want. I already have 15,000 miles on this car.
