Anyone who knows me will be aware I love calculations .
Wanted to know if my fuel system could support the use FTW 120+purple & 1000bhp in the car.


First normal fuel
1000bhp fuel has bsfc of .62 so 653Lb/hr or 6853cc/min of injectors required. This is achieved with 8x1000cc @ 86% duty.
Convert 653Lb/hr to Imp gall/hr = 91 gall/hr required.
e98 based fuel
1000bhp fuel has bsfc of .87 so 916Lb/hr or 9616cc/min of injectors required. This is achieved with 8X1300cc @ 92% duty.
Convert 916Lb/hr to Imp gall/hr = 127 gall/hr required.


Cant find the bsfc for Purple but it uses 10/15% more fuel than e98 so that means 146 gall/hr pump required.

My Automotive Eliminator Pump
supplies 125 gall/hr @ 13.5V we can run it at 16v via the Accuvolt which if gains are linear would supply 148 gall/hr. Im sure it don't work like that so my present pump would struggle to supply 1000bhp using Purple.
Injectors would also need to be bigger than 8x1300cc. This is some Fuel
