Hi, Rusty....regarding the skinny metal, I assume you are referring
to the EWP.
No, I was joking
about having a skinny metal RV-3 to fit this all
in.
Do you have the Meziere
pumps?
Nope, I've got two
Davies Craig pumps.
It does sound logical to go with the two
EWP's and dump the mechanical pump. Save weight , have redundancy, and not rob
precious horsepower from the engine.
All valid points of
course. The other thing to consider is the incredible reliability of the
mechanical water pump, and the fact that it's 100% proven. Tracy
often points this out, and he's right. As long as you can keep the belt
on, the pump itself almost can't fail
catastrophically. Adding an EWP in series gives extra flow
that can be turned off and on, eliminates cavitation issues at higher RPM,
and provides a backup pump in case the belts go flying. I can easily look
at this as gaining redundancy, and performance for only two pounds. Sounds
like a bargain.
Eventually, once I'm
convinced that the EWP is rock solid, and reliable, I could remove the
stock pump, and add the second EWP. With the turbo, I already have more HP
than I should, so the extra few HP gained by removing the mechanical pump
is a non-issue.
I do like the adapter plate that Meziere
has for the rotary engine. Did I say I like bolt-ons? Take
care. Paul Conner
I used to like bolt-on's
a bit too much, which is why I have (had- that sounds better) a
big ugly cowl. I should have taken the time to do it right the first
time. You seem to be smarter than I was, since you've chucked
the intake from Atkins, and fabricated a new one that fits the cowl.
I'm paying for my impatience with the rev
2 redo.
Cheers,
Rusty (no longer
going to Delray Beach- thankfully)
