Heine,

I need a little help interpreting the data. First I did a double-take because of the rpm where the power and torque curved crossed. Then I realized the units of measure were different than I was accustomed. Is HK Swedish horsepower and is this very nearly 1 US HP? Correct? On torque, if I convert N-M to Ft-lbs I get 578 ft-lbs which looks about right if 1HK ~= 1HP, then the power and torque values are the same at about 5250 rpm.

Now what I don’t quite fully understand is where the power level is being measured or inferred. The car is shown on a chassis dyno. Is the indicated power level at the wheels or crank? 618 HP with that cam, 750 carb, and stock Pantera mufflers (if this is so) seems like the power level is being projected at the flywheel or BHP. Is that so? If so what is the assumption about power loss through the drive train?

Best Regards,
Kelly
