* Dew Point is a helpful temperature to know as it tells you approximate-
ly at what temperature you can expect to see moisture on the track sur-
face. As you can see from the example above, the racers at Top Gun
Raceway won’t need to worry about any dew on the track surface since
it is extremely unlikely with those weather conditions for the temperature
to reach 21° F.

note:
Your calculator’s ET predictions may vary from other ET predic-
tion sources primarily due to traction. The Hot Rod Calc assumes ideal
conditions with no tire slippage and 100% converter lockup, and the
predictions are for estimation purposes only.
Calibrating your Hot Rod Calc for eT Predictions at the Track
When using your Hot Rod Calc for ET predictions at the
track, following these steps will result in the most accurate
predictions. you should go through these steps at each track
you race at during your dial-in session to establish a
Baseline HP. The Baseline HP value will be the number you
use for that track and that day.
once you have selected your dial-in ET in the morning dur-
ing your dial-in session, enter your ET, vehicle Weight with
driver, and enter your track’s conditions when you recorded
your selected dial-in, including Elevation, Moisture, and Air
Temperature. Solve for your Baseline HP, and record this
number. Here are the steps:
