eT Prediction and HPc
Building off of the previous Basic ET Prediction example, let’s
zoom your 1970 Ford Mustang notchback to Top Gun Raceway in
Fallon, nev., and calculate an ET prediction using some additional
inputs. The inputs demonstrated in this example are not required
for an ET prediction, however, this example will demonstrate the
Hot Rod Calc’s
ability to calculate a Horsepower correction factor
(HPc) and output for current weather conditions as well as MSA
conditions.
For this example, the track’s Elevation is 3,963 feet above sea
level. Recall that our race car weighs in at about 3,840 pounds,
including the driver, and produces about 411 HP in ideal or MSA
conditions. The current local measured weather conditions are
73° F, absolute Pressure of 25.88 inHg and 14% relative humidity.
