High Flow Water Pump?

TPIPARTS.NET state their water pump increases flow by 30% They do not say who the manufacturer is so I assume it is thier product? The price is very attractive. Do you think the gain is real...

Let me know what you think.

Looks nice..... Ask them for some flow data, running through a radiator. I doubt that they have any....
CSR makes claims like "30% better" etc. When asked though they will tell you that their tests were not done through a radiator, just straight out of the pump.

If your stock WP is still in good condition, I think your money might be better spent on a new radiator.

Agreed. I think I will call them. I do have a brand new dual core radiator. But since I have this all apart for the cam any, thought I might take advantage of a better WP. For a buck sixty five, and if it really does flow better, what the hell....

Very true... Let us know what you find.

Never mind. I emailed to get flow data and the response was that the product has been discontinued by the manufacturer.

Regardless that the product is no longer available you have to ask what benefit is there to a higher flow pump. I don't think there is any. The problem is heat exchange and I can't see how accelerated flow helps, in fact it might hinder the process. I bought a Meziere Electric pump and discovered that it's great for the 1/4 mi folk but for us road racer types it doesn't help anything. You have to place some trust on the GM engineers for figuring this stuff out. All the same i will be looking for more cooling out of the radiator though.

one thing to worry about with water pumps is once the impeller spins past a certain speed you can get cavitation where the flow will actually drop

That'll destroy your pump too, not a pretty sight, but I'd be more worried about that if you didn't have enough coolant in your system.

Thinking about it now, your probably right. There should be a calcuted flow rate through the rad to ensure proper cooling. if that get negated by a faster flow you might just be asking for trouble. I already spent a lot of mony on a special rad for this product. I think my work is done on the cooling issue. Some times you see something and you think, gotta have it....

The laws of Thermodynamics can show you how it helps. Flow is directly related to the rate of heat exchange, the faster the flow the more heat transfer that occurs over a given time.

Most all electric WP's are rated with NO hoses, radiators, or heads and block on the pump, they are sucking water in one side and spitting it out the other. Its easy to get a high GPM. When these pumps are loaded in a full system they usually perform worse than the stock pumps. I learned this after buying one and testing it……waste of money.

Surface area and true GPM are the most important..

I have a secondary cooling system.
