Race-gas
I'm not bummed about losing a race as my car in not a race car per say.
Those turbos spool up when there in the upper RPM's thats for sure. He sounded more like a jet than a car and I was surprised to hear his "jet engine" over my open piped big block as mine sounds like a funny car when its wide open.

There is 4 pages of info on my engine from the builder but I think this info should due for whatever you need.
So you know, Kenny is the builder and he is the one who implored that I run this thing on at least 100 octane. I tried during an emergency to get by on 92 pump gas and everything seemed cool till i went up a decent size hill and loaded the engine.....not good. I hate the sound of pinging.
When I started my build my intention was to build a street/strip car. Unfortunatly or fortunately I waivered from my original plan and built more of a G-car than a drag car.
No worries though. This motor is awesome and doesn't care if I race it or cruise it. It's a happy motor as long as I feed it good fuel.
