It can be calculated from basics if you know the b.s.f.c of the fuel. Its something I do for all the fuels I use. I can go into the maths but most just glaze over & think im some sort of gimp. For instance pump fuel has a a bsfc of .6 a decent race fuel .8 & the FTW Purple I will use is 1. It means the Purple will use 67% more fuel so you cant just assume what you say above.
Done a google search this may help- Use .65 for pump fuel & .8 (80%) for duty cycle.
