Actually race gas slow's down the flame front in the combustion process, the engine is now running in a too-rich condition on lower compression stock motors which would mean cooler.
The bottom line is this: let's say your motor needs 93 octane to run correctly and you fill up with 115 octane wonder gas. You will not run any faster. In fact, you might end up running slower because of a radically slowed flame front.
You don't get any increase in the performance with racing fuel. Not a bit. Not any racing gas. Good racing fuel allows you to run your timing more radical, to extract more horsepower out of what you've got.
Race gas will absorb more heat and tends to cool the intake charge, most is leaded above 100 octane. I would consider using the 100 octane unleaded Sunoco pump gas in my stock motored SEEG to make the motor run cooler in the summer.
