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
