John didn't dyno on both dynos on the same day either though, so it it is hard to say exactly what the difference would be. Most of the people I have seen dyno 2WDs on both get about a 15% higher number on a dynojet or dynapack going off of Mustang dyno numbers.

It's hard to say if the drivetrain loss should be a simple percent though. I read some page a while ago with a more complex drivetrain loss formula that had some loss built into it. So that a car making a lot more power would actually have a smaller percent loss than one making a lot less power.

It's all just numbers though. If you took a 100% stock awd and put it on whatever Vishnu's dyno is you might think there is 40%+ drivetrain loss when going off the factory HP numbers(who knows if those numbers are correct either, they obviously weren't on the RX8s or SRT4s). Think of the heat that would be created in the tranny if 40%+ of all the power was dissappearing in it.
