16 Blade water pump?

[WHITE AND RED 69]

I was comparing water pumps and came across a 16 blade high flow pump? I've only seen up to 8 blades? Seems like it wouldn't work right with that many blades but am just curious if anyone has ever used one?

Cavitation? maybe, but I thought moving the water too fast wasn't good either

The overheating thread stickied at the top of this forum has some pump comparisons I believe.

from what I read, the high flow pumps are junk

I agree too many blades, read the thread , where all the after market pumps are tested, I had that paper weight that 440 source called high flow water pump, it actually did worse than a stock unit, after reading the thread here replaced it with a 7 blade heavy duty cooling package one from ma mopar engineered and designed all those years ago , works great and no more high temps

I'm not looking to buy it. I just thought is was overkill with all the blades and wondered if anyone had seen anything like this? I've read the overheating thread a bunch of time but the most blades that one compared was 10. I was shocked when I saw a pump with 16.

I've already made the mistake of using a false claim pump once. Won't be doing that again.

I can see a high volume pump if you have a over sizes cross flow radiator to a point, and it is a small point at that.

My self, I run 1974 440 A/C pumps, they have smaller vanes, gives you 5 extra HP at 5000 RPM's and water stays in the radiator longer to cool the water better.

All my hard to figure out over heating problems have turned out to be lack water flow in the radiator, or clogged up mufflers!

the AC pumps are supposed to have smaller vanes....because of pulley ratios

Vanes are in the water pump A wing 383. While pulley's may be smaller (I need to check the DC Bible) the pulley sizes does effect the vane sizes, speed they turn yes, sizes no.
