I think Steve BeckHam can answer those questions as the early Power Sport engines
use Airflow Performance fuel injectors.
-- 
Paul Lamar ...No rotor no motor.

Thanks Paul..  I couldn't remember who said they had been using the
Airflow Performance..  Yes, Steve Beckham.


Matt-

Also many racing engines used mechanical fuel injection.
Here is a picture. Also a rather grainy picture of the PS engine.

BTW guys please look at all the Youtube videos and click on the fifth
star over where it says ratings. A good search phrase is RX7 Airplane.
That gets you to the right place. Than click on More From: UTUBPLEASE
That will show you all 18 rotaryeng.net videos.

We need to promote RX8 sales as Mazda needs to keep making rotary engines
until some other major manufacturer wises up and starts making turbo
compound rotaries for street cars. I suspect Mazda management lacks
a bit of vision on this subject or they would have done it years ago.

The piston engine guys are going to have a heck of a time with
turbo compound as half the heat and kinetic energy goes towards
destroying the exhaust valve. The exhaust valve was the  Achilles heel
of the CW R3350TC. CW spent most of the development money dealing with
that problem.

Also keep an eye on Popular Science or Pop Mechanics.
Reputedly there will be an article by Don Sherman on the
turbo compound truck engines shortly. Send email to the mag
and tell them how much you enjoyed the turbo compound article
whether he does a good job or not :)

paul,
my experience, and referral to Don Rivera's manual, indicate Airflow
Perf generally uses electric FI pumps on LyCont.  I have both a cam
driven mech pump and an electric Boost Pump on my Lyc 0-360 w/ FM200.
Ck his website

Thanks Steve.
