Hey Guys,
This newsletter is beginning to sound like that "Other One"! Mostly theoretical prognostications and very little actual experiment.
Now it just so happens that you don't really need to waste your time doing all this. All the PRACTICAL test data has been done. It will flow 80 litres a minute @ 7.5 amps. That's 1300 IMPERIAL (not US) Gallons per hour!. All the test data and flow specs for different head pressures are all on the Davies Craig website. http://www.daviescraig.com.au.
However, what really matters is "Does it ACTUALLY work??" and "Does the pump cool the engine??" These things have been on the market since 1999. They have been fitted to engines as varied as 1000 BHP ski boat motors, 300 BHP circuit race cars, as well as hundreds of "normal" road cars. I'm off on holidays for a month beginning next Monday so I'm on short finals right now. But to put to rest this issue once & for all, on my return, I have a comprehensive test regime planned for in-
car/on-dyno testing. As anyone on the automotive game will tell you, if you want to subject an engine to heat stress, stick it on a chassis dyno! More engines have been blown up on chassis dynos than any other form of activity.
More details later, stay tuned ...
Best wishes & kindest regards,
Leon Promet

I don't think we can estimate squat. If we could find a coolant
flow transducer in a maybe 35-40 mm line, Tracy and Ed could
patch it into their radiator hoses and measure what the
by-gawd-for-really flow is under various conditions. That done,
it would be simple enough to get some various EWPs patched into
the system and find out just how much electrical power it takes
to generate that flow. For the reference flow figures, the
airplane would have to be flying under the conditions tested.
For the EWP test, the engine wouldn't even have to be running.
Simple as that (not to be confused with easy ... :o)
Just a theory .... Jim S.
