SAE paper 900035

I had lost this paper in my filing system for a few years
but there is a lot of interesting stuff in it. Hopefully
Petri can look up a better copy. Mine is awful with many
pictures that are totally blacked out.

The most interesting is the lower cost hydro formed hollow
e-shaft that drastically cuts the weight.

Also there are some charts comparing charge cooling with oil cooling
pertinent to the Rotamax engine.
