yea so u multiply by 1.15 to get bhp. well an estimate atleast

Thats if your frontrak, there is normally a 22-25% or so driveline loss for quattro, so multiply your whp by 1.22-1.25 to get your chp. So 312 x 1.25 = 390chp. Thats using a 25% driveline loss.

RE: New numbers

Actually flyinb501 is right, you divide WHP by .75 to get an approximate CHP for quattro. We have approximately a 25% lose through our drivetrain which means that our WHP should be 75% of our CHP.

312*1.25=390 (this would mean CHP is 25% more than WHP but that's incorrect)

312/.75=416 (this means that WHP is 75% of CHP)
