IMHO, a driveline loss of 14.5% is pretty darned good. For comparison, my Marauder with it's long drive line and automatic slush box loses closer to 20% from flywheel to driving wheels.

The SS sounds awesome on that dyno vid, btw. Can't wait to start seeing these in person.

"Net" meant "with all the accessories" -- stuff like water pumps, alternators, fans, etc. that cause drag and that that weren't required under the older "gross" rules. Even so, however, there were no hard-&-fast proscriptions about the actual testing regimen, which meant fudging the numbers was the norm. A few years ago (someone will chime in with when), the SAE published very specific guidelines for measuring engine output and most manufacturers complied, providing the first "accurate" power numbers for new cars and also providing, for the first time, a meaningful comparison between different cars, whether from the same or different manufacturers.

FWIW...
oh ok, thanx, that cleared it up for me :thumbsup:

About 11% loss on LS3 motor with man. trans. 426 HP at crank you should see about 379HP at wheel. Maybe a little more or less depending on how good a motor you got from the factory
