I still want to know how you're going to establish what the flywheel/crank HP number is on a car that doesn't have a flywheel, and is on an older, slipping auto.
My car threw down a whopping 103hp/110tq on a Mustang in a previous iteration, ther'es no way to translate that to crank HP except comparing to an identical car with no mods in factory optimal condition and referencing the original claimed hp/tq formt he factory, which may or may not be valid
Devil's advocate here, but I know more than most about heartbreaker dynos and how the numbers extrapolate to real life....
