Anyone else find something off with these numbers? Not only did we lose almost a 100 hp through drivetrain loss, the RS4 lost almost the same despite being an all wheel drive car.

Interesting to note however the torque drop off after 5,000 rpms...which incidentally I have noticed on high speed runs!

I should have a dyno next week, I will keep you posted.
there also seems to be a big difference between a mustang and a dynojet with this car due to loading.

Interesting stuff. They admit in the article though that the Dynapack Dyno they used was probably calibrated different then the Dynojet that Lexus used. Definitely interested in seeing more Dyno numbers
