the 150 BHP Alfa quotes for the stock car is at the crank, isn't it?

How much should I get from an stock Alfa at the wheel. I though 136 bhp at the wheel was pretty good for a 30,000 mile car. You'd expect at least a 10-15 bhp drop from the crank to wheel.

I once dynoed my bike (Yamaha R1) and that was supposed to have 150 at the crank, rear wheel showed 142 bhp. A loss of 8 bhp for a simple chain drive. Given a cars more complex transmission you'd expect to loose more.
