Joe,

I installed a Renesis WP on my 20B. It is much lighter than the 20B pump and is more compact. If you use a custom inlet/outlet, you could run the lines very close to the engine. Mine are inside the c/l of the slide throttle.

A point of clarification... The Renesis WP is part of the Renesis front cover. Using a band saw, I separated the WP housing from the front cover. So, I used the 20B front cover with the Renesis WP.

Someone on the list is using an EWP. I don't remember who at the moment.
Maybe he will chime in later.

Bill,

My installation does not have enough room to use the stock RX7 pump. I have
a Toyota Corolla pump that can with some modification be mounted on one side
of the motor. I had to get a Denso alternator to get an alternator to fit
along side the motor. I found a block that permits connectionof hoses to
where the pump used to be. The reason that I am asking all of these somewhat
strange inqueries is just to get a working scenario. My firewall is 22"
wide and this is a pusher so things get worse as you go aft. Another item
that takes a lotof room is the exhaust augmenter. The engine is also a P
Port. I do not believe I can get the cooling right without some additional
means. The shape of the cowls on a canard pusher is critical to effiency so
i am trying to stay tight.

I saw a video on a RX7 discussion group that used the Stewart EWP using the
similar block connection. Don't know if it would work in an AC.
