Calculations for injector size
assumptions for both engines -
BSFC- 0.48 (stock)
Duty cycle - 80%
Naturally aspirated
QR20DD- 4 injectors, 150HP(stock)
flow rate =150*0.48/4*0.80
= 22.5lb/hour
swept volume = 2000/4=500cc
VQ30DD - 6 injectors, 230HP(stock)
flow rate =230*0.48/6*0.80
=23lb/hour
swept volume =3000/6=500cc
