I know that hp at the wheels is typically 20-25% lower than at the crank due to driveline losses... What about torque? Does the drive line also consume 20-25% of the torque?




There is no possible way that there is a 20-25% loss. I would say closer to 10% and 15% on the extreame high side. I had my Turbo Buick on the rollers(dynojet) a few weeks ago and made 840 HP @ 26# boost and ran out of fuel pump. Going back tomorrow and hoping for 1000HP. At this level, If you assumed 20% then something would be melting off the car assuming the loss would be due to friction.
