9/91 E100/pump is about 3.63/gal

This is just to get you to a safe octane rating. As we noted before, race gas will have more energy content than E100, so you'll make more power (and wear) on the race gas.

Thanks as always BLUE200OS,

Nice of you doing the arithmetic, I flunked that class. Pretty much my how I've been running it the majority of the time (8:2 piump). I usually wind up using toluene in pinch. It's a lot easier to find, in most hardware stores, than race fuel.

Ive got a custom made h2o/methanol injection sittimg on a shelf. Sure to relieve any angst with an effective octane well over 100 oct. on any grade pf fuel(from what I understand). Dont quite understand it but, Ive heard of people claiming the equivalent.118 on a 50/50 meth h20 mix, a little less with straight h20.

Regards. PK
