Are LS water pumps interchangeable?
LS1 WATER PUMPS AND LS TRUCK ENGINES You can use LS1 water pumps for truck engines, but a water pump designed to fit a truck engine is not used on an LS1 due to water outlet height and pulley offset.
What way does a LS water pump turn?
LS1 to current LS engines have a water pump that rotates in an anti-clockwise direction with extra idler pulleys to allow the direction change. Our clockwise rotation pump means the pump pulley rotates in the same direction as the crankshaft.
How many GPM is a stock LS water pump?
The standard 42 GPM pump is suitable for normally aspirated engines up to 650HP.
Is electric water pump better than mechanical?
Although numbers vary, electric pumps will typically flow two to three times as much as a mechanical pump at idle RPM (because electric delivers a constant flow rate, while mechanical is scaling with engine speed), but once the engine rpm exceeds 3,000, the pendulum swings in favor of mechanical, and above 6,500, as …
How do I know if my water pump is reverse rotation?
Water pump pulleys running on the INSIDE surface of the belt indicate a STANDARD ROTATION water pump. Water pump pulleys running on the OUTSIDE surface of the belt indicate a REVERSE ROTATION water pump.
Can reverse flow damage pump?
Reverse flow will make an unpowered centrifugal pump spin backwards. These pumps are not designed to rotate in reverse, and can be damaged if they reach a backward speed much greater than their forward design speed.
What happens if you run a water pump backwards?
A common myth is that in reverse rotation, the pump causes backward flow, that is, IN the discharge and OUT the suction. In reality, a pump operating in reverse rotation because of wiring or phase change will pump in the normal direction. Now, it won’t pump very well. Its flow will be reduced, as will its head.
How many gpm does a car water pump move?
According to Meziere, most mechanical pumps tested in V8 applications flow approximately 8 GPM at idle, and around 70 GPM at 6,500 rpm. This is very good flow while at that RPM. However, it’s after a run on the race track or full throttle acceleration in a street car that an electric pump really shines.
Are electric water pumps Streetable?
And as those at Moroso and Meziere believe, and as many enthusiasts have found, electric water pumps can be right at home on your high-performance street car just as well as they can on a dedicated drag car.
Do you need a check valve after a pump?
When the pump shuts off, gravity wants the water that is in the discharge pipe to fall back into the pit. The check valve is there to prevent that from happening. The check valve prevents the pump from having to re-pump that water out which could result in short cycling.
How do you know when your water pump needs rotated?
Rotation is indicated on the head of the pump, you’ll see an arrow going counter-clockwise. This is the direction you want the pump spinning. If you turn the motor around and look at the backside and remove the cap, you’ll see a shaft located in the center.
Is a high volume water pump better?
It would be a lie to say that a high flow water pump won’t help reduce cooling temperatures, but it’s not necessarily the truth to say that it will solve overheating issues. A high flow, or high volume water pump will help increase flow, helping to move coolant faster.
