Mark,
In looking at your pictures, I couldn’t
see where you used the band saw?? Is the shape of the two water pumps so
similar that you can just cut one off, smooth the cut edges, and bolt it up to
the other front cover?? For that matter, if it was originally a part of the
front cover, why would it have bolt holes to bolt to the other cover??
Confused!

flow
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

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.
