Impressive Paul & Larry, I gotta say.. to see the very first
complex casting I've ever designed on screen..
It's pretty cool.. I hope it's only the start of many more.
Having access to full NC machine capabilities.. sure makes
a difference!

Best

Thanks Jarrett,
Now I can't wait to machine them up! I will load test one, and them
destructively fail test it to see what it's ultimate strength is. If all
look good, we will build production tooling.
Next casting will be an aluminum water pump housing that is lower profile,
and will mount dual 55 amp alternators. The entire set up will provide the
security of dual alternators and weigh less than the stock cast iron part.

Move it down low Larry as that is one of the problems with the stock
pump. When the water gets low in the block it starts to cavitate and it destroys
the pump housing. Kind of dumb for Mazda to put it up so high. Probably
an out growth of the old engine driven rad fan.

The RX8 and 3rd gen pump are much lighter than the old cast
iron cartridge version.

We built some remote pumps for the second gen pump cartridge. Did not sell
all that well. People won't spend money unless they are forced :)

I was going to suggest reviving the remote water pump as a follow on
project. Paul, they may not have sold very quickly but I think you sold
all of them and I seem to recall some interest later when they weren't
available.  I purchased one although I haven't put it to use.  I
relocated the alternator to the cool side because of not much room on
the top.  Building a bracket was going to be a major headache.  I used
a Pineapple racing alternator bracket and it was so low that it really
cramped the water pump installation.  I would suggest developing a
bracket to go with the WP would enhance acceptance.  If you can develop
a WP/Dual alternator or even a single alternator combo that will mount
on the cool side with the WP near the bottom of the engine it should be
a real winner.

Having said that, I also think the market for these items is always
going to be, shall we say, SLOW.  In the long run it will be beneficial
to always have the items on hand for whenever the user gets ready.
Availability and a complete system are the key.

My opinion FWIW
