In the mean time I am working on increasing the flow :-)

Yes; and hopefully the effort will produce results.  I find it hard to
commit to that mod until it is shown that the flow in the loop is noticable
improved.  And how will we know?  Are you going to measure the flow rate
through your cooling system with the "new pump"; and then also with a stock
pump so we can see the improvment?  That would be good science.

And do these measurements pretty soon, so I know if I should send you my
pump :-).

Well if the cooling gets worse I screwed up :-)
Its all theory Al. Less restriction more flow. E=IR or I=E/R.  E is pressure,
R is resistance and I is flow. The main reason I did it was to cut down the
height of the pump. If you don't need that reduction in height run the stock
pump.  What kind of airplane are you building?

BTW I am done doing pumps for awhile. You might try me at a weak moment some time
in the future :-)
