Marc, pretty well summed it up. Happy with the P port, but muffler noise is hard to tame. Still have that problem with the 3 rotor.

Speaking with the same full authority - I would think it would make more sense to go the 3 rotor route vs turbo or P port.

The greatest gains with a Turbo are seen above 10,000. Sure you will get some HP bumps starting out - but you weigh more and you need to have an intercooler (more drag).

I know for turbo-normalized aircraft - they are generally seen as slower until about 8 or 9 thousand. Not saying this would be true for you (as I assume you would go for positive pressure not just SL) and by the sounds of it you already have a baseline engine you are working with and just trying to save money which a 3 rotor would not be.

Dave,

            A few of us in OZ were discussing your engine with full authority (Called ignorance) and wondered what engine you have and what your thoughts are re the turbo. Is it worth the effort?? Just looking to save the P port cost, and get a slight HP boost, with the muffler problem eliminated. Does it actually work that way, or is it too much grief? Neil.

everyone agrees that although the sound of my rotary is a cry for attention, It does make the best smoke of the group.

Here is a picture of the pump placement

I have smoke on my plane, I just used the same pump as the EFI pump that Tracy used to sell. it weighs less than a pound and puts out about the right flow rate. Built in check valve. I have not problem with leaking. instant cutoff. Tank is in the wing and pump in the wing root which keeps the system and oil smell out of the baggage area.

The rotary makes nice hot exhaust which is great for supporting a lot of oil without leaving a residue (except for the 2-stroke oil)

This is made to control fuel to primer ports on a carb'd engine, but would probably do the job. No idea how well it would survive the heat of the engine compartment, where it would need to be for a quick/clean cutoff. Maybe mounted low on the firewall away from the air exit, with the lines running uphill to the smoke port on the exhaust?

The last message that I seem to have received from the list was 11/19. this
is a test to see if I have inadvertently been dropped.
