G'day Paul,

You miss read it  Leon. Two rotors. It is 300 cc per rotor 600 cc total
about the same as a Mazda one rotor.

"Displacement 294 cm? per rotor."

Nah, ... nah, ... nah!  Please go and have another look at the site.

Sez:    Displacement    Single rotor - 294 cm per rotor
Sez:    Power Output:   53 kW at 6000 rpm. Alternatively 68 kW at 8000 rpm.

Copied this straight from the site I did!  No Bull!

OK yeah I see that! Probably a Limey error converting from the real English
system of measures to the silly metric system :-) PL.

For what it's worth,  these look like they are basically the same engines
that Mid-West engines are "selling??".  Vapour ware???.  Just like the
Wankel GMBH stuff that never happened.   I'm pretty sure that it's the old
Norton motasickel stuff. Good motors,  but for some reason,  the stuff
never seems to actually get on the market,  usually because of financial
shenanigans.  It seems it's just a bait to continually relieve "investors"
of their money.  Lot of these around.  Can't be too careful.

I agree about the Norton bit.
No I think they are actually used in UAV's. There are a lots of UAV's around
because they are relatively cheap compared to a manned recon aircraft.

How's my turbo intake manifold coming?

Can't get a position on the mandrel bender for another 10 days.  In the
meantime, I have had further thoughts. I've been talking to other pattern
makers around these parts.  looks like I might be able to get a set of
patterns done for about 2 ~ 3 K..  Going to have some discussions over the
next couple of days.  I'm off later today to see one bloke.  He makes all
the low volume stuff for an engineer mate of mine. He's just done some
trick Nissan V6 and Chev V8 stuff for multiple throttle bodies.  I need to
have a good talk to him.

Talk to you later on.  Cheers,

Good work. I do believe that a casting is the way to go.
BTW I had an idea about that problem bolt in the upper right hand corner
of the flange. If you counter bore a relatively large hole through both walls
of the runner you can then use an internal wrenching bolt (hex drive)
to fasten the manifold to the engine. Then all you need is a threaded
plug to seal the runner. Need a drawing? This is a trick some hot rodders
used to get larger intake runners in some U.S. V8's.
