Also some of that 30hp is going to auxiliary equipment which os unaffected buy more engine power

Coefficient of friction is not what I'm talking about, neither Mu K or Mu S. When you have friction what else comes from that? Heat. What is heat? Heat is energy.

The faster you spin a transmission, while the friction may not change from one gear on another, the friction of the clutch does. And so does the friction of the fluids inside the transmission, the diff and everything else. Increased friction is increasing heat. The more heat you produce the more energy is lost.

Transmissions are fairly efficient. Usually between 98-99%. The torsen diff we have on this car is fairly efficient as well, the lowest efficiency being 95%. These percents are because it takes heat and friction (parasitic loss from energy and the transferring hp) to move them.

Take all the Effiencies of the rotating parts from the flywheel, down to the wheels and you'll get your whp rating. @stugray @Koa @Ultramaroon
