Congratulations Sandy on engine first start.

Those blat test are great. Just the kind of stuff I love doing. What kind of
fan was used.

What cooling configuration did you wind up using?

Paul Lamar



Greeting Paul, et al,

First of all, I want to thank you for all the advice and help you've given
me with this engine. I don't know if I could have done it without you and
the guys, but y'all certainly made it easier. And, your book was a big help,
too.

I'm using a Warp Drive, High Horse Power, 66" diameter, carbon fiber, four
blade (ground adjustable)

I designed my cooling system using two 2.25" cores in a horizontal "V"
configuration with a total of 720 ci and two wedge intakes described in your
book [see attached pictures]. The oil is cooled via an oil/water cooler
located down in the pylon. The radiators and oil/water cooler were welded
for me by Ed Klepeis at Techwelding. Hot engine water is routed to the upper
radiator for the first cooling, then to the oil/water cooler, then to the
lower radiator for a recooling, finally back to the engine. I installed temp
sensors at the intake and exit of both radiators so I can see exactly how
efficiently the system is (or is not) working. If that set up doesn't work
then my next plan is to run coolant through both rads and then the oil/water
cooler to get a greater differential temperature for the oil...just depends
on if I need more water cooling or oil cooling. I'll keep you posted.

Thanks much,
Sandy McNabb
Renesis in a Glass Goose

Nice work Sandy.
In the case of the limited cowl volume Glass Goose the oil water heat exchanger may be the only practical thing that works for the oil. I like the rad layout.

Rino's Glass Goose is cooling but he lives in the Great White North :)
