Thanks for the info. I think it's time I updated my knowledge about the P water-cooled engine and looked at an exploded diagram of the internals. Seems like an extra shaft in the process would increase the friction, and therefore rob energy -- but I'm sure a couple of engineers at Porsche musta thought of that beforehand.
