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. Notice the outer housing on this water pump. The style of the housing on this water pump may vary. On occasion we have noticed the housing to not have the spiraled ribs on it, but rather a straight ribbed design. They are from the same manufacturer.
Pictured below is a file photo of one of our one of our TSP water pumps with the back plate removed to expose the cnc machined aluminum impeller. This is a far superior pump compared to those with stamped steel or cast iron impellers. This is an expensive upgrade, and well worth it, in our opinion.
This is the last water pump you ever have to buy!
Warranty is valid regardless of street or strip use.
The aluminum 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.
Here is a story to prove our point.
We had just installed a stroker engine in a 79 C-3 Corvette and had converted it from mechanical to electric fans and could not stop the car from running hotter than we were comfortable with. The temp would soar to 235 in as little as ten minutes. We then replaced the OEM cast iron water pump with one of our aluminum water pumps with the aluminum impeller. We knew that an aluminum water pump, especially one with an aluminum impeller, could reduce operating temps, and it certainly did reduce the engine temp by approx. 10-15 degrees. We now use this water pump exclusively on all of our turnkey engines we build.
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, and we proved it.
This pump is half the weight of a cast iron water pump with no sacrifice in reliability. There are no drawbacks to running this type pump, other than cost.
If your pump is still mounted on the engine, the way to tell long from short is that there is nearly no space between the timing cover and back of the water pump IF YOU HAVE A SHORT PUMP. The long pump will have nearly 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.
