Hi Paul,

I see a slide throttle on this view and what appears  as  injectors on the
inboard side of the throttle plate. Other pictures show an injector outside
the slide throttle.  Did MAZDA have two injectors per intake?

Also others might be interested to know that lack of adequate compression in
my test engine is prompting me to tear it down and rebuild it.  Short term
setback, but long term time gain I think. I won't need spend months fiddling
with the car engine to run with a mess of stuff that I won't be using for
the airplane. I will go right into P porting it, three spark plugs each
housing,  a slide throttle, and initially  trombones for testing best tuning
length only. In short a half Lemans plus the Renesis rotors front plate and
water pump. Oil system will be wet though since  my radiator is behind the
firewall in back of the engine.

Probably as the engine was generating about 175 NA HP per rotor.
That is a lot of HP (fuel) for one injector.
