Nitrous/fuel ratio Quiestion
 

Does anybody knows what is the best Nitrous/Fuels ratio for a rotary engine.

A chemically correct nitrous to fuel ratio for gasonline would be 9.65 to 1 and a ratio of 4 to 1 will be awfully rich.
Now where in between this two number is the magic number for a rotary?

I think you answered your own question, but if you haven't figured it out, run it richer than 9.65:1 and leaner than 4:1 :D
