I can understand what you're saying Chris...the only point that I was trying to make is that it seems silly to have to run anything higher than 93 octane in a naturally aspirated car. If it's tuned correctly, in my mind the only major things you should be worrying about engine wise on a race car is oil pressure, oil distribution to the entire engine, and whether or not the engine has a good enough cooling system.

The whole point of running race gas, especially leaded, is to give you a much broader range to play with the timing curves and turn up the boost whilst avoiding detonation, as you already know. It's to make a lot more power safely, which simply doesn't happen with NA engines. You'd be lucky to see a 10whp difference with C16 on a tuned NA car.

I'm sure somebody will come up with a link to prove me wrong hah, but I can't see ever wasting the money for super high octane fuel in an NA car. I certainly wouldn't waste the money on a tune for it. Once you throw in a power adder of course, like nitrous or a blower, then all of that goes out the window.
