Hi Rick,

Thanks for the encouragement.  I KNOW the EWP works.  
However,  to PROVE to the "unbelievers" that it DOES is another 
matter,  but in the fullness of time,  it WILL happen.  

However,  it's NOT a trivial exercise (not to mention the expense) to 
organise a datalogger,  set up and calibrate 15 - 20 or sensors to 
monitor temps,  and pressures, and flow rates.  Then book a 
chassis duno,  allocate the time to be present while the whole test 
regime is done. The same goes for doing it on the road.

At each stage,  there needs to be back to back comparisons with 
the stock mechanical pump and the EWP.  So to be valid,  the 
same dyno test regime has to be done twice.

The final trick is once all the road and chassis tests have been 
done,   the SAME motor needs to be put into an airframe and fly 
that SAME motor with the same sensors using both the EWP and 
the stock unit  in the SAME aircraft.  That way, 99% of the 
variables are removed,  and  there can be NO argument about 
methodology from the naysayers.  

However, for a more immediate qualitative test,   if it can cool a 300 
BHP 13B turbo running flat out on a chassis dyno for a few 
minutes,  and I measure the current draw at the same time,  on the 
reduced basis of proof of "on the balance of probability",  that 
SHOULD be more than sufficient to at least shut up the 
mathematically challenged.

Accordingly,  the motor (a mild ported '89 model 13B turbo Series 
V  is now together,  it will go in the car sometime over the next 
week or so,  and I can start testing in a couple of weeks after that 
once I have carefully bedded it in.

I spoke to my buddy with the new dyno yesterday.  He's 
overbooked until after Easter (there is a big drag meet coming up),  
but immediately after Easter is organised.  So I should have the car 
side of the testing all done by the end of April.  I'll do it in that week 
after all the drag madness rush is over.  That should satisfy all but 
the most rabid of naysayers and theoretical intergalactic rocket 
scientists.

However,  I can't tell you when I will actually get it into an aircraft.  
Maybe by mid year at the very earliest.  As I don't have an aircraft, 
so I'm reliant on others. Maybe Todd Bartrim will have something 
happening soon aircrraft wise.  I did offer a cast iron money back 
guarantee to any believer who wanted to try one.  

If it didn't work as advertised,  I'd cheerfully refund ALL their money, 
 AND recant publically,  and seek absolution fo my folly

Unfotunately,  the moderator of that "other place" was SO sure that 
it was a scam after having "run the numbers",  that he didn't see 
the need to back up his hypothesis with experimental data. 

 Boy is HE going to get a shock!!  (As an aside,  I notice that he's 
gone into the water pump design and manufacturing business).

I'll keep you all posted.  I'll post the proposed test regime 
sometime next week when I have some spare time to finish editing 
it.. 

Cheers All,

Leon
