High octane fuel keeps high compression engines from coming down with a bad case of head knock... still an engine with 10:1 compression and a knock sensor like the Crossfire, running very high octane, will fool you ECU and therefore it will advance the timing on your engine... and there lays the HP gain from running high octane gas. How much HP I don't know... but give it a shot brother, but be ready to hold onto the steering wheel. Just remember high octane does not produce more HP, your timing of the ignition spark does, understand?

Also if you want to move a little faster only put a couple of gallons in the tank, keep the weight down.

Let me know how it turns out... hooah
