Low speed torque and driveability ?

Don't forget that you lose about 25% of your power between the flywheel and rear tires.
I think that the actual formula is .80 for a at and .85 for a mt. I've read this in several magazines, I may have the numbers crossed. If it's right say that you have 325 flywheel horsepower and you have to at you would divide 325 by. 80 equals rear wheel horsepower. I've heard the 25% thing for years

The fact is I’ve never see a 25% driveline loss.

The only way to KNOW what the drive train losses are is to do a coast down. That will tell you exactly what the loss is.

Claiming a standard 25% means that the numbers will always be higher than they should be.
