JET, Ah! yes it does. Good point. Lucius is talking net horsepower which is at the clutch.
Further mentioned:
The plots show that Hale's formulas predict a much lower 1/4-mile elapsed time (ET) and a bit faster terminal speed (mph) than is typical for modern street cars. Hale's formulas may be more appropriate for strictly race-track cars that have better traction and drivetrains than most street cars.
Generally, this is typical of a well-prepped car like CB's car when referencing the Patrick Hale formula.
All the cars in the results thread posted have nearly or 100% stock drivetrains. Though AWD increases traction it certainly adds more drivetrain loss than Patrick Hale was working with. And Hale was still working with cars with great 60ft times.
As you can see, actual performance for the most part falls between the predictions of the LRT and Hale formulas, with the Fox formulas doing an excellent job of matching performance when engine power exceeds 500 bhp.
To me, that is a good conclusion; as Hale was working with cars with great traction (modern advancement in traction techniques), but less drivetrain loss. So, it would appear that, for accuracy, the Fox formulas apply here since they are compared with a stockish AWD drivetrain similar to the T/E/L and matched better. These guys havn't done much to alter that basic platform. The Hale formula would be very conservative with an AWD DSM.
I'd be curious what a well prepped DSM could do with one of these turbos.
