The VP C85 is a very good compromise between gas, and meth. You get real cooling, but not so much that you can't get heat. Corrosion is negligible compared to meth. Half the cost of race gas, and makes more power than gas because of the O2 in the fuel. The C85 also has MTBE, as a further oxidizer.

Ive ran meth in carbs, and injected, and it is for sure the way to go if you're making big power where that's all that will work. Gas is too hot in the summer, and meth is a pain in winter. E or C85 works great in both.
