How much HP does an electric water pump add?

Meziere says, “We can usually show gains from seven to 14 horsepower at 6,500 rpm.” Some OEM-style mechanical water pumps may also not hold up to the high-RPM use often associated with high performance and drag racing engines.

Are LS1 and LS2 water pumps the same?

LS1 and LS2 pumps are nearly identical. They both have water outlets on the upper passenger side. However, an LS2 pulley is smaller in depth and their thermostats are not the same. Also, the LS1 pump provides a better seal and larger bearings.

Are electric water pumps better than mechanical?

An electric water pump is more efficient and more in tune with your engine’s specific cooling needs. See pictures of car engines. Without it, the engines in our cars would quickly overheat and possibly grind to an ugly, costly halt. Wonderfully clever as they are, mechanical water pumps do come at a cost.

Are LS water pumps interchangeable?

The LS1/LS3 pumps are interchangeable; the LS3 pump uses a lighter pulley, with about 4 pounds of weight savings. The crank pulley is part of the dampener; it is one piece as opposed to a separate pulley that bolts to the balancer. This correlates to the water pump as well.

How long does an electric water pump last?

Water pumps that are original should have a service life of 100,000 miles or more. Cheap replacement water pumps may not last long before they leak. If a customer’s old water pump has stopped working, you should recommend a top-quality replacement water pump.

How many amps does an electric water pump draw?

The pumps from Meziere and Moroso all draw from eight to 12 amps under continuous use, while possibly spiking a few amps higher at initial start up, which is the case with many electric motors. “Our heavy duty pumps will take no more than 12 amps as a steady draw,” says Meziere.

How long will an electric water pump last?

Is an electric water pump good for street use?

Any street/strip car is a good candidate for an electric pump, except for the extreme turbo applications.

How do I keep my LS engine cool?

The preferred LS drive-ratio is 1:1. Stacking additional coolers and/or A/C condensers directly in front of the radiator reduces efficiency. Run a cooler 160-degree thermostat and turn on the fans at about 170 to 175 degrees (10 to 15 degrees hotter than the thermostat).

What vehicles have aluminum LS engines?

It would instead be the series of iron-block, aluminum-head LS engines produced under the Vortec brand name for Chevrolet, GMC, Cadillac, and Hummer trucks that would greatly expand the family. These are found in displacements that included 4.8-liters (LR4), 5.3-liters (LM7, L59, LM4), and 6.0-liters (LQ4, LQ9).

How often should you replace your water pump?

60,000-100,000 miles
Facts and figures: a working water pump only needs to be replaced after 60,000-100,000 miles, so if you have your car for less than 10 years, you may never have to worry about it.

What are the signs of a water pump going bad?

Five Signs Your Water Pump Is Failing

• Overheating. A dead or dying water pump cannot circulate coolant through your vehicle’s engine and, as such, the engine will overheat.
• Coolant Leaks. Coolant leaks from the water pump are common and a clear sign that it’s time to replace the pump.
• Corroded Water Pump.
• Whining Noises.
