Where
VE = volumetric efficiency
CFM = engine air flow rate - cubic feet per minute
CID = engine displacement, size or volume - cubic inches
RPM = engine speed - revolutions per minute
NOC = number of cylinders
BORE = length
STROKE = length
HGV = head gasket volume
HGCT = head gasket compressed thickness
PDV = piston deck volume
DPD = deck to piston distance
VPD = volume of piston depressions
VPB = volume of piston bumps
SV = swept volume
CR = compression ratio
CCV = combustion chamber volume
ISH = injector size per horsepower
HP = horsepower
