That range sound about right, perhaps more in the 295-3-5 range. Figure on a 6-speed car about a 15% loss of HP from the crank to the wheels.

Typically drive train loss on an A4 or an A6 is about 20%.

They are all different - that's why I said "typically"...there are always the occasional anomalies. Is your car a MN6 or an A4? Because for an MN6 that is right in the expected range. With an A4, that's a little higher than the 20% calculation....if so - that's great!
