Guys,

Things have been a little too quiet on the list lately, so I thought I would
post a flight report on the Renesis water pump conversion I
recently completed on my 20B.

I recently converted my 20B to accept the Renesis water pump.  I did
this after weighing the two and found that it would save 6-7 lbs.  While it
was more work that I had estimated, it turned out well worth the effort.
After working through a persistent misfire issue over the past few weeks
which was cured by careful attention to the CAS setup, I was finally able to
take to the air last weekend.  OAT was 69-70* @ 2,500 msl and there was a
3000' ceiling, so I didn't go any higher.

Things went very well, climbing out at 6700 rpm water got to 175*, oil to
185*.  Circling at a modest 25.5" MAP, water temps dropped to 143*, oil
settled in at 160* (my oil temp target).  Adding power, I saw the oil
temps starting to creap up a bit, bumping 165*.  Cowl flap was left open
during the entire flight.  Needless to say, I am very pleased.

It should be noted that in conjuction to the Renesis water pump, I added a
Laminova oil/water exchanger.  It is connected to the coolant return
line and in series with the oil/air exchanger.  I measured a 10* increase in
coolant temp through the exchanger.  I haven't measured the oil temp
drop yet.  However I estimate the oil temp drop through the exchanger to
be 20-25*.

Mark
