Maybe....but we're short on pillows. Could you spare some?

He is greedy when it comes to those damn pillows. :shakes head:

The claimed engine power is not always accurrate, can be much higher, sometimes lower. Most cars will lose 12-18% through the drivetrain, 15% on average.

They don't test every motor, the 332 is an average.

But this number can change from day to day and especially dyno to dyno.
If 17% is the magic number? That means the Z is overrated. Crank to wheels its supposed be 15%. I'm guessing the british 326hp at the crank is the right number???

Very interesting. The genesis coupe 3.8, is underrated by 20hp. It runs 306 but runs about 280hp at the wheels. We run 326 at the crank as well. Crazy how much faster we are considering realistically, we are running the same exact power.

Well! Glad we all had this discussion!

The Z has a very inefficient drivetrain, hence higher loss.
