What is difference in dyno numbers???

What is the typical difference between power to the wheels and power at the crank?

I thought there was a 10-12% variance???

Example: 400 at the crank = 360 to the wheels.

Correct or no???

usually more drivetrain loss for a rwd drive car closer to 15% with a stick and a little more with a auto.

So it's more like 400 to the wheels = 340 to the crank?

Oops, meant to say 400 at the crank = 340 to the wheels.

Thanks for the clarification...

lot of variables though, trans type, rear end, gears, or for me stall size. so its never an exact science.
