Reply to "horsepower loss through the ZF"

Wow, so the average parasitic loss for the the ZF car aproaches 20% or more? That's significant, perhaps worse than a RWD Ford with a Toploader and TL or DL rear. Who has actually tested that in a Pantera? I'd love tosee the actual dyno results. More conventional cars with T5Z or Tremics in a RWD configuration generally see ~18%. And while parasitic loss is somewhat fixed, the difference in the real world if you are talking 300HP, 400HP, 500HP remains fairly constant. If you are talking a 3.33x spread in HP like from 300 to 1000, then yes, the factor will change.
