HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

High Flow Water Pump?

Post  Bluemach1 on Mon Jul 11, 2011 12:28 am

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...

Here is the link:

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....

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....

Here is the rad i bought: [You must be registered and logged in to see this link.]

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.
