i'm guessing there for either cuase the website i got the info doesn't discriminate between n/a and forced induction, now that thats all out of the way, wortdog - is my fuel pump not big enough? its a 255 lph, i found an equation to calculate the fueling i would need but i'm not sure if its right....
Turbocharged engines typically need BSFC fueling of about 0.60 lb/hp/hr, a reasonable first guess for fueling required on E85 would be 0.77 lb/hp/hr (BHPgasoline x 1.05) x BSFCe85 = Estimated E85 fuel requirements (350hpgasoline x 1.05) x .77 = 282.975 so would i need a fuel pump that pushes 282+ lph? |
