Calculate HP with HP Correction
For a great software program try Larry Meaux's Pipe Max.
His program is excellent and will provide a lot of info.

These equations are for recreation only.
This calculator uses the Motorsports Standard Atmosphere (MSA). (Not ISA - International Standard Atmosphere)
Grains - Grains of water vapor per pound of dry air
The HP Correction is a better determination of ET than the DA (Density Altitude).
I have included them for your benefit.
