Ok...here we go again...(maybe).
Talked to a guy/company making water pumps for just about everything on the road. Mostly machined aluminum.
Who out there would be -
1. Interested in impellers only, that would increase the efficiency by about 100% (or twice as much), to install on "your" stock pump.
2. Interested in a complete aluminum, bolt-on water pump.
This is all in the, lay-it out on the table stage, and I'll be sending them a pump assembly and if there's enough interest, a whole water pump manifold so they can see "exactly" what they need to do to increase the efficiency and longevity.
Unfortunately, because the stock pumps don't seem to have a long life, there's no way to remove this proposed new impeller once it's in place without warping it, or special home made tools. So bad bearings in the pump would also require a new impeller.
Leme know......
