I want a polished or chrome water pump for my new engine. Which is the best for the price? Will summit's work? Also are the electric ones a better choice? See sig

I'm a little confused by the question. What do you mean by "performance"? Are you looking for more engine performance, or better pump performance?
A pump that moves a lot of coolant at higher pressure differentials will usually take more power to turn (less engine performance). A pump that takes less power to turn will usually provide poorer cooling system performance (and eventually less engine performance).
Care to define?

I want better cooling performance. Basically one that will be ble to keep my engine running at a cool temperature but at the same time not costing tons of money. The biggest bang for the buck.
Stewarts hands down is the best. I won't even touch any of the other pumps just because of their lack of technical support. Stewarts can offer better pumps for less and still have money for R&D should tell you something.

The two pumps I wouldn't use on the streets, are a chrome or electric water pump...
Chrome is not good with heat, and an electric will not increase as rpm increases, and is a hudge drag at criuse rpms...
You can get a polished or brushed/bare aluminium, or you can paint a stock unit. Some of that newer anodized paint look pretty neat...
If you want increased cooling, for the price an overdrive pulley might be the ticket...(I have March pulley on mine)

I've got a electric Proform cheapy $129-$149 depending on where you look and it's going on it's 4th year without a hiccup. Absolutly NO cooling issues at at, but I also have a 31x19 aluminum radiator to back it up. Hottest I get in dead of summer in traffic 180*, but gauge spends 90% of it's time on 150*. That's freeway driving, in town, racing, etc....
We're running a CSI (now CSR) on the truck I race with a comparable motor to mine, smaller aluminum radiator (S-10) and it has trouble keeping it's cool...bad part of the deal....it's track only.
Proform is a knock off of Meizere, so if you have to have the name brand go with them.
For a stock engine, a stock replacement pump is sufficient, and if you buy it through your local auto parts store, it will most likely come with a warranty.
yea this is an old post, but just to add to it. The Horse Power Tv guys did a Lean Mean Green 91-92 Camaro build up and used a electric water pump for a daily driver.

Not that i really take anything they air on TV or publish in these car rags with any merit or seriousness that i'd make apersonal decsion based on what "they say" I would have to agree based on the exellent luck i've had over the years running the same proform electric water pump.
