I’m not sure where you’re going with that........

If you want to get a better idea of how much power is being lost with the motor going from the dyno to the car, you need accurate weather data from when the runs are made, and having the actual track elevation too.

Then correct the runs to a std day at sea level.
The difference between the calculated std day hp and the STP power from the dyno is what is being wasted in the car.

One of the new Wallace calculators takes the drag run data, and weather data...... gives you a net power rating, and a correction factor for STP power(at least, that’s what I think the correction factor is doing).

Since we have all that data for Wades last track outing, it shows:
