Engine Flow ( wa) lbs/min: 14.7*lam1*sqrt(0.803653082089*relFp1/2999)*fuelDutyPri1/100*4

0.803653082089 is the Sqrt of the 565cc injectors @ 43.5psi to lb/min (petrol flow)
4 above is the # of Cylinders

Engine Volumetric Efficiency: (((14.7*lam1*sqrt(0.803653082089*relFp1/2999)*fuelDutyPri1/100*4)*(639.6*(460+Tm)))/(map1*0.5*rpm*vd))*100

·R = Gas Constant = 639.6
·Tm = Intake Manifold Temperature (degrees F)
·VE = Volumetric Efficiency
·Vd = engine displacement (Cubic Inches, convert from liters to CI by multiplying by 61.02, ex. 2.0 liters * 61.02 = 122 CI)
