Has anything come of the discussion some time back about ways of improving
coolant pump flow rate?  The specs I got from Dave Atkins for the "high
performance" pump (whatever that is ) is 37 gpm @ 6000 rpm.  This sounds
like the standard Mazda pump and may be about right for the 13B, but
certainly below optimum for a 20B.

Does anyone know a contact/source for the TEMP radiators that Fred had
mentioned?  I like the idea of the staggered fins to improve heat transfer
to the air.

Al,

  Here is the website:

http://www.tempinc.com/

  I never contacted them because Fred implied that their stuff is really
pricey. If you talk to them and get a quote I'd be interested in hearing
what they charge. Ive been getting quotes on conventional racing type
aluminum radiators. Looks like the best bet to me so far is CR Racing at
about $300 for a 2 row rad in any size that I choose.

  And Im still interested in the water pump upgrade also. Paul Y. and Jeff?

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
now-a-days for water pumps. Any of you guys have one apart to look at?
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.
