Remember et is from early in the run and MPH is from the end of the run.

I number of years ago I did a simulation of an NHRA Pro Stock motorcycle. I was off some but the engine builder / crew chief looked at my inputs and gave me some gearing and HP and Torque changes. I then hit the different times and MPH. I said to him the only way I can get that et with that MPH is to run out of RPM before the finish line. His answer was me too.

Does method work with your Stock or Super Stock car?
