To nitrous or not?

Good luck , hope it holds up to all the power you'll be making
Thats kind of why I posted. I want to make sure I don't go over the limits. Also considering jumping on the E85 bandwagon. I really want to drive the car and at my comperession I'm limited to running race fuel. Its right around $10-$12/gal whereas E85 is around $3/gal
