If the impeller in a stock Mazda pump has straight blades I suspect it can
be improved with backwards curved blades which seem to be all the rage

I might be able to work something out. There is a ASME paper out
on the subject. I will try to look it up at the UCLA library when
I get back. Remind me later. Jeff and Paul Yaw seem to be too busy.

There's nothing wrong with the impeller.  Its the housing that's screwed
up.  My fix design is done, machined, and flow tested with the housing
only.  I'm still waiting for PY to test it on a running pump.  If anyone is
getting anxious and can provide proper test setup then speak up.

Please hold your answers until I get back next week. I will re-upload
this if I remember.
