If you meant BHP, then the calculator is wrong.

I am using 84% injector duty when running 20% methanol mix at circa 490BHP, and you need 8% more fuel flow compared to the equivilent pump fuel only, when running with a 20% Methanol mix.

99RON fuel is the equivilent of the USA 95PON fuel, it's nothing special, normal everyday super unleaded pump fuel over here.

These are well tested injectors and have been used to produce 600BHP on normal pump fuel.
