2. Calculate water vapor content by subsequent presses of :
(Water Vapor Pressure)
(Saturation Water Vapor Pressure)
(Dew Point)
Dew Point is a helpful temperature to know as it tells you
approximately at what temperature you can expect to see moisture
on the track surface. 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.
Repeated presses of [Moisture] will toggle back through the inputs
and outputs, starting with the relative humidity input.
Basic ET Prediction
Note: Your calculator's ET predictions may vary from other ET
prediction 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.
Given your 1970 Ford Mustang Notchback, with a 411 HP-
producing, stroked 351 CID engine, weighing in at about 3,840
pounds (including driver), calculate a simple elapsed time (ET)
prediction. For a basic ET prediction, the calculator only requires
vehicle weight and HP to be entered. The entered HP is assumed
to be the engine's rated HP in ideal or MSA conditions with no tire
slippage and 100% converter lockup.
First, clear the memory on your calculator, including temporary and
semi-permanent entries
