Hi, Rusty.....best of luck on first run of your rotary. I need to ask a
question. I also have Dave Atkin's throttlebody and intake manifold, however
I have the straight manifold rather than the wrap-around. I am interested in
possibly using the wrap-around manifold like you have, but I am concerned
with cowling clearance on top of the engine. My cowling just touches the top
of the spin-on oil filter, and I need to move my alternator to the side, as
it's origingal location is too tall for my cowling. Does your system stick
up above the engine as high as the alternator? If it does, I might possibly
cut the manifold on top after the bend, where it is horizontal, have an
extension made and then weld the end back on that the throttlebody attaches
to. Then it would be similar to Paul Lamar's manifold, except that I could
still use the throttlebody that I got from Dave Atikins. I would like to
stay with that system, as the electronic ignition harness is allready wired
for those injectors, etc.
The reason for these possible changes are because I am now considering
the addition of a turbo, as an inconel muffler for a pusher would cost
approximately what the turbo costs, but the turbo would increase power,
where the expensive muffler will not. With my present setup, I could not
mount a turbo, as the intake manifold comes straight out from the engine.
Comments or suggestions? I forgot which turbo you are using? Thank you for
your input and suggestions. Paul Conner, Mobile, AL

Thanks for the additional comments. I really don't expect the initial run
to be too much of a problem, and I do plan to let the engine come up to
normal operating temp as long as all is well, and I can top off the water as
it runs. I'm using an aftermarket RX-7 AST (air separator tank), with the
vent coming from the outlet on top of the engine on the flywheel end.
Should work OK.
Cheers,
Rusty
