Along with the ability to pack the necessary horsepower within tight constraints of space and weight, and carry enough fuel for the length of the run.

Schochimetric air/fuel with gasoline - 14.7/1 by weight., 0.5#/hp/hr is a good target for BSFC.

Methanol is in the neighborhood of 5.5/1 AFR, nitromethane is an oxygen bearing fuel with an AFR nearing 1/1! % of nitro obviously affects AFR.
