Isn't the drivetrain loss in manual Z's estimated at around 17%-18%..?? I think 25% is a bit high..

This is pretty much my next question. Why 1.25? Where are they getting it from?
Instead of:
Quote:
292 (Wheel HP) x 1.25 = 365 at the flywheel.
230 (Wheel TQ) x 1.25 = 288 at the flywheel.

Shouldn't it be:
292whp x 1.20 = ~350hp
230wtq x 1.20 = ~276tq
Then using that 1.20 to finish out, their final numbers would be:
340whp x 1.20 = 408hp
260wtq x 1.20 = 312tq
Is this the wrong approach?
