Once you get into the 7- and 6-second realm, there is no longer a pretense that the car will be driven on the street. So on a car like that, the compression goes up, the boost goes up, the timing gets aggressive, and you run a dedicated race fuel. I'm sorry to hear you're disappointed in the mileage, but I think your 13:1 engine is going to have a helluva time trying to run on pump gas even with the computer doing all its cam timing, fuel trim, and spark advance tricks to keep detonation in check.

You may have issues on a 93/torco blend too. How are you going to consistently get the octane rating your engine needs blending torco and 93? Serious question. Curious as to what your plan is. 10 gallons one can situation? I don't trust that.

Very solid points, fellas.
