    900 fwhp at .6 bsfc, and 43.5 base pressure will require 85lb/hr at 80% duty cycle. 800 fwhp can get away with 75lb/hr.

    Hello,

    Maybe a little late but here's some info, Mnlx is right on the calculations, however there's a little more practical (and fun) way of doing it, in the form of a mobile App for iPhone or Android plus a lot of other useful EFI calculations. Look for EFI Math.
