CHROME OVER ALUMINUM HIGH VOLUME SHORT STYLE WATER PUMP WITH A CNC'D ALUMINUM IMPELLER
AVAILABLE IN LONG OR SHORT VERSION. THIS AUCTION IS FOR THE SHORT VERSION.
This water pump has a cnc machined aluminum impeller. The rotational weight reduction is considerable. Most all other water pumps have a stamped steel or cast iron impeller. This water pump is considered high end street/strip grade. These water pumps sell for over $150 at all major retailers. For those wanting a lower cost water pump, see our other listings.
The chrome finish is decent. You may notice that in the crevices and corners the finish is not as smooth, and we also notice a few pin-head flaws in the finish. This is only visible up close. Most every brand water pump with a chrome finish will lack perfection in its appearance when observed up close. When mounted on the car surrounded by pulleys, belts and brackets, these imperfections are not noticeable.
For those wanting a less expensive water pump, see our other listings, but we do consider this unit the best value, and highest quality. The aluminum impeller is a very good feature, as well as the overall quality of this pump.
This is the last water pump you ever have to buy!
Warranty is valid regardless of street or strip use.
Below is an excerpt from our ad of the lower grade water pump with the cast iron impeller. It's fair to say that the same or better results can be expected of this water pump. Do bear in mind that the alum. impeller in this water pump is designed to reduce rotational mass, and dissipate heat at a faster rate, and that's a plus for any car.
We had just installed a stroker engine in a customer's car and had converted it to electric fans. We could not stop the car from running hotter than we were comfortable with. The temp would sore to 235 in as little as ten minutes. We then replaced the oem water pump with one of our former models that did not have the aluminum impeller, and still had the same problem. We had heard the aluminum impeller water pump did have a good design, and thought we would give it a try, and to our surprise, this stopped the overheating problem immediately. We now use this water pump exclusively at our shop. Most aluminum water pumps have stamped steel impellers or at best machined iron impellers, and claim to be high volume. We have used other brands and styles of water pumps on stock engines that are not modified, and don't seem to have heating problems, but for vehicles with modified engines, this is the pump to run. We proved it. Bottom line to this story, don't use a water pump on your street rod, especially in very hot climate, that's not a true high volume, and the moral to this story, is that not all so called high volume water pumps function the same. We have seen so many people claiming their car is running hotter than they want it to. We now know what to recommend for them.
This unit is all aluminum and will flow water unlike any others we have tested. Continue reading!
This pump is half the weight of a cast iron water pump. For those wanting to paint this pump with a contrasting color, it would come out very nice and take painting well. Aluminum water pumps will also dissipate heat better than cast iron. There are no drawbacks to running an aluminum water pump, other than cost.
If your pump is still mounted on the engine, the way to tell long from short will be that there is nearly no space between the timing cover and back of the water pump, IF YOU HAVE A SHORT PUMP. The long will have at least one full inch of space in that area.
PLEASE BE AWARE OF THE MANY INFERIOR WATER PUMPS ON THE MARKET. WE FEEL THIS ONE IS THE BEST AVAILABLE. IN YEARS PAST, WE HAVE SEEN INFERIOR PUMPS THAT BREAK OFF AT THE PUMP SHAFT CAUSING SEVERE DAMAGE TO THE CAR. OUR PUMPS HAVE HAD NO SUCH FAILURES.
Compare before you buy.
On very rare occasions, we have had a few complaints of water seepage coming from the back plate. We noticed on a very few that the amount of sealant used on both sides of the gasket may have been insufficient. We strongly recommend removing the back plate and coating each side of the gasket with a good quality sealant before installing the water pump on the engine. This is a very simple procedure. The complaints concerning this issue are few and far between. Besides this minor issue, these water pumps have been extremely reliable.
BE SURE OF WHAT STYLE WATER PUMP YOU HAVE. THE LONG PUMP IS A BETTER STYLE PUMP TO USE, IF POSSIBLE.
