Dynoing an AWD car FWD...

[czech09]

If someone offers you dyno #s for his AWD car but he dynoed it FWD, are those #s different than if he would have dynoed it AWD ? How much of a difference could it be...?

Thanks.

Yes they are different. There will be more drivetrain loss if it was dynoed on an AWD dyno. MLopez did an AWD swap on his Spyder, in FWD he made 412whp, on an AWD dyno he made 389 to the wheels. Just because less power made it to the ground doesn't mean he actually made less, just more was lost through the drivetrain.

That's what I thought thanks.

Hrm... less than 5.6% loss... interesting.
