Paul,
Pity about the rotor housing not being possible, having them made with

PP

would be a winner. How much would it cost for the DG coating on a rotor
housing at a guesstimate?

My wild ass guess is $500.

That is dear !!

BTW a lot of die cast have silicone in the aluminium - makes it run

easier

especially for thin areas.

We use 356 T6 do you know the composition?

I don't, but the chaps doing the casting should !  I will try and find out.

The Intermediate and end housings with the plate was what I was

referring to

perhaps someone will bite the bullet and run a test engine - I've always
liked
the idea, taking into consideration comments on different rates of

expansion

etc.

Can you draw a line on your cut down plate and give an idea of where you
 would run the seals and bolt attachment points.

I don't follow you here.

Sorry -where the O-ring sits (in the cut down Intermediate and end housing)
between the aluminium section and the steel plate and the attachment points
holding the two together (as seen in a front on view)

You have your barry mount running horizontally, in this drawing, rather

than

vertically (as in the plate design) - any reason for that ?

That is primarily because the engine would be cantilevered off the front
end housing with a significant bending moment. So the rubber axial loads

would be rather

high. Common practice in AC motor mounts prior to dyno focal.

Secondarily it is simple.

 Thanks again,
And good on the chap who is doing the trials on the two piece houusings,
I will be eagerly watching to see the outcomes, perhaps he can give us a
regular update.
Nothing ventured, nothing gained !!
