Hi all,

Here's my first post to the list.

I was looking at the Racing Beat web site and saw they have aluminum housing available. What is the experience with these? Things like heat transfer and thermal expansion come to mind. I know they are real expensive but the weight savings is attractive. Is there any data out there on these housings?

Jim has several hundred hours on the dyno at the 300 HP per rotor level.

Alturdyne claimed they ran some in a one rotor BD 5 motor but I am
not sure if it flew. Their main business was gen sets.

Here is an idea I had a while back. The cut away shows what you must
do to get the water to go where it is supposed to go.

Paul, did you cut the housing open on this picture?  If so how did you do it.

I did not do it but it was done on a mill. Probably with a fly cutter.
Note: you don't need the side ports.
