Has anyone tried one of these? There on ebay for 60.00 bucks.
-
this is the 3rd listing on Ebay in less than a week so 20+ sold (at least). from what I have heard everyone seems pleased with the quality of machining (no one has ran one though).

Does the listing, have any details of materials used to make these pumps/shafts. Looking at the pics some have posted, they look good, just wondering about the material quality.

I have wondered the same thing, Neil. People have been eating these things up, yet no one has asked what material they are using or even where they are made. For all anyone know, they could be pumping these out of China. The ebay listing is not terribly transparent. Not knocking the product, just seems to be a lack of information.

And they call it a "high flow" impeller when you can tell by looking at it the impeller is the exact same design as the oem impeller. Wouldn't that make it a "regular flow"?

I would think so. It looks like the impeller would need to have some change to it, like more blades or something to be high flow. Flow to some extent though, is controled by those thin metal defuser plates between the gaskets.
Those shafts being stainless is a plus. Now if they only had that big seal included, that would be a deal.

Anyone have a report on these? Are they holding up?

A buddy of mine sheared the shaft on one last weekend. I'll try to have him send me a pic.
-
Here's a pic of where one broke. Both are boss pumps and shafts
-
My cousin's also broke after one weekend

Well that’s not good! Just FYI, I am making some new pro grade water pump shafts.they will be above oem grade. I’ll start a thread about them soon.

Too bad the boss shafts aren't working out. I would be interested in at least two. I missed out on the last batch you made

how well have your original shafts held up. I got one from Jared when I bought his QC cover. Haven't used it yet

Thus far I have only heard of one person wearing one out. It didn’t break, just wore down. He did have a lot of hours on it. My next ones will be hardened steel. Harder and stronger that the oem ones. I’ll start my thread soon and explain. Got impellers coming soon also.

This is good to hear. Thanks for putting forth the effort to keep our toys going
