I think you'd have to contact one of the dyno manufacturers like Dynojet, Dyno Dynamics or Maha. There will be an algorithm/formula in the software which will allow user input of a restricted amount of input parameters.

Numbers gathered at the rear wheels should always be just that. They should not be converted to some wild guess drivetrain loss correction.

If you want flywheel HP numbers, gain those from an engine dyno.

The quickest way to slow a car down is to use a dyno to gather the wrong data, for the wrong reasons.

Sometimes I wonder about the total fixation on maximum HP output. At our local auto cross, the perpetually dominant Boxster is a 2.7L bone stock (other than an IMS Solution) 986 with a five speed. He regularly hammers highly modified cars with seeming ease. It ain't always about horsepower............

Amen to that! I'm currently hunting down a couple of Z06 Vettes.
