This program will estimate the horsepower output required to move the vehicle to
the 660' track marker based on vehicle weight and elapsed time (ET). It will also
adjust horsepower corrected to Standard Day weather conditions.
4 Est. 1/4 HP Page 32
This program will estimate the horsepower output required to move the vehicle to
the 1320' track marker based on vehicle weight and elapsed time (ET). It will also
calculate horsepower corrected to Standard Day weather conditions.
5 Est. ET/MPH Page 32
This program will estimate the 1/8-mile elapsed time (ET) and MPH plus the 1/4-
mile ET and MPH from engine horsepower and vehicle weight.

1 Calc Ratio Page 37
This program will calculate engine compression ratio from cylinder bore,
crankshaft stroke, combustion chamber volume, and piston dome volume.
Piston deck height, head gasket volume, and supercharger boost pressure
are included in the equation.
2 Calc Chamber Page 38
This program will calculate the required combustion chamber volume from
cylinder bore, crankshaft stroke, and piston dome volume when a
compression ratio is specified. Piston deck height, head gasket volume,
and supercharger boost pressure are included in the equation.
3 Calc Dome Page 38
This program will calculate the required piston dome volume from cylinder
bore, crankshaft stroke, and combustion chamber volume when a
compression ratio is specified. Piston deck height, head gasket volume,
and supercharger boost pressure are included in the equation.
4 Pour Chamber Page 39
This program will calculate the engine compression ratio using the cylinder
bore, crankshaft stroke, and the measured liquid volume poured into the
combustion chamber of an assembled engine with the piston on top dead
center (TDC).
5 Pour Dome Page 39
This program will calculate the effective piston dome volume by measuring
the piston deck height, installing a clear plastic plate in place of the cylinder
head, and then measuring the poured liquid volume in the void.
