I am sure it pulled some due to the higher intake temp, but the actual difference in power is marginal at best. No way I buy into the whole knock sensor is sucking power out of the car BS, especially on a stock vehicle and the 370 especially. Racing gas is $6 or 7 bucks a gallon, I can spend the money on another track day.
I would be more worried about crashing than mechanical failures

i never said i can "feel" the difference in power, nor have a monitored the difference with telemetry. I dont bring it up as a performance advantage, its just a little extra insurance by raising the detonation threshold a bit.
Also, i didnt say fill up your tank on race fuel, i said mix in some so your over all effective octane is higher. I do about a 1/4 tank of 100 mixed with the 3/4 of 91 ill already have in the tank (since all be have out here in socal is primarily 91 octane and that is what my car was tuned on)
a few gallons of race fuel is not alot of money, and its a nice bit of extra safety. Ive done it with all my cars in the past, both my street cars that see track duty, and my past competition time attack car and because of this ie never ran into detonation related problems or failures
