Hey, Todd.  If I put any more items on my projects-to-do list, I would have to ask the Man upstairs for a much longer extension {:>).  I would love to do more experimenting, but feel its time for the "younger generation" to take over the reigns. 
 
How are would it be to slap the mechanical pump back in your installation - I mean its to cold to fly up there in the winter time anyhow {:>)

I think Ed is just trying to egg me on, knowing the attachment I have to this subjectJ.

            Referring to Bob who reported marginal cooling with his EWP, it would have been nice to know how the system would perform with a mechanical pump. I’m satisfied with the performance of my Davis Craig EWP, even though it is somewhat marginal on hot days during a 3 minute 2000fpm climbout with boost. But I doubt the mechanical pump would do any better. I’d like to improve my cooling system, starting with my hailstorm damaged evap cores, but I’m still committed to using my EWP.

            I guess until we can get a true experimental minded type of guy who already has a successful mechanical cooled system, to switch over to an EWP with no other system modifications, then we will never really answer this question.

            Gee Ed, you sound bored... It’d be a great way to pass the summer?

I was just thumbing through a recent catalog from Summit Racing and came across a couple of pages on electric water pumps.  There has always been a degree of interest (and some debate {:>)) regarding the use of electric water pumps in aircraft.   

 

Are you really that bored Ed?  Maybe trying to stir up some lively conversation, and tired of the same old fuse breaker topic :-) 

 

I'm off to run the single rotor again, now that I've got the RD-1C drive back on it.  Don't tell anyone, but it's only got an electric water pump :-0
