bullet2JZ-GTE air consumption
bulleta Turbo Sizing spreadsheet - great info! (even better when we put more turbos in it)

air lb/min -> bhp -> rwhp approximation -> fuel gal/hr

bulletbhp = 10.86 * lb/min for an intercooled engine according to Ray Hall Turbocharging's calculators
bulletrwhp = .85 x bhp
bulletfuel gal/hr = air (lb/min) * 60 (min/hr) / (12 (a/f ratio) * 6 (lb/gal))
bulletassumes air to fuel ratio of 12:1, and 6 pounds / gallon for fuel
