So I would expect that for reaching 1000 bhp on regular fuel would require about 3x 1.52 x 60 = 273 liter/hr. So do you need more than 2.5 times more fuel because you are using race fuel?
Dont work like that calcs below.
400bhp on pump & 1000bhp on FTW.
Brake specific fuel consumption (BSFC) of pump fuel=.6 of FTW = 1.0
fuel required = target bhp X bsfc = 400 X .6 = 240lbs-hr for 400bhp
= 1000 x 1.0 = 1000lbs-hr for 1000bhp
convert to gal/hr
= lbs-hr/ weight of gallon = 240/6.34 = 37 gal/hr for 400bhp on pump
=1000/6.34= 158 gal/hr for 1000bhp on FTW
convert to lit/hr X 4.54 = 37 X 4.54 = 168 lit/hr for 400bhp on pump
= 158 X 4.54 = 718 lit/hr for 1000bhp on pump.
The other problem is the psi the pump is required to supply the fuel at.
400bhp @ 30psi = 53 (static) + 30 = 83 psi.
1000bhp @ 60psi = 53 (static) + 60= 113psi.
At 80 psi my Aeromative can supply = 575 lit-hr
At 110 psi it drops to = 285 lit-hr
