Most of the rule pumps are only rated to a couple feet of head pressure, on boats they just have to move the water into open air. (Bilge pump) As long as your back pressure the pump has to push against is low then its all about volume. They cavitate easily from some playing around I did with them. Was trying to build a sprint car -pre heater.. Ended up stepping up to a davies.
I'm running a Rule 2000 in a 5 gallon water tank in the trunk and 1.5" hose to/from the Chiseled Performance 1500hp a/w intercooler under the hood in a '69 Chevelle. They recommend the Rule as it works.... I'll have data on it this summer logging it all with a Holley Dominator.

Normally we just let the hoses hold it up.
its a PWM capable pump. If you have that output on your ecu.

We had pumps crap out on us constantly on the dyno because we were using dry ice/methanol to cool the charge. Always made for more impressive dyno numbers for magazine articles.
We starting using cheaper rule pumps which failed at about the same rate when pumping fluid at -100* F. From there, we started using $30 harbor freight well pumps. Heavy bastards, but man those things worked.
How any of this is relevant to the topic, I dont' know. But I just had a root canal and these meds are making me talkative.

Just buy the pump from a ford lighning or gt500 . They run around $100 on amazon. I have one in my whipple 2.9 set up and with an Afco heat x my temps run 25 over ambient . It's all about the heat exchanger and fans .

I am hoping the Rule pump I have works well. But also be aware that you can actually move water too fast in a cooling system. I needs to flow at a rate that allows it the time to remove the heat from the air side.

The problem with high water speeds is turbulence, cavitation, and friction. In a well made system, these are much less of a problem.
I would be glad to argue that point. I was a certified test and balance tech for over 10 years dealing with air and water flows for companies like IBM, 3m, Applied materials, Motorola ect. Including clean rooms and system/production tools. I was also certified in HVAC Psychometrics. Flow Rate does make a difference. That's why there is a specified flow rate in all AC systems. Remove the thermostat from your engine and tell me how long it takes to overheat. It overheats because the water is moving too fast for the air from the fan to cool the water, which removes the heat. Yes, too much speed can cause flow issues including cavitation at the pump or around anything that allows air to build up and yes it can increase friction.

I've never had a thermostat in my car, and its never overheated.
Sure, if you move liquid too fast in a radiator, the temp in vs temp out will be less than if it was moving slower. It constantly circulates, it doesn't go through the radiator one time.
You can't argue with thermodynamics. If you know HVAC, then you know the equations for heat transfer all include flow rates, and the more you increase that flow rate, the higher the heat transfer rate.
Cooling capacity is usually decreased because you are adding another source of heat to the equation. Anytime you compress anything and raise the pressure, you raise the temperature. The pump alone will generate heat when moving at a faster speed, drawing more energy, etc.
I could go on for hours. You're more than welcome to bust out some math.

Maybe if I put my setup it will be easier to guide me on what pump to use .
This is the intercooler Overall Dimensions are12"x12"x4.5"
Core Size 10"x4.5"x4.5"
The air inlet and outlet are 3" diameter ends which will accept 3" hose couplers.
The water size connections are 1/2" NPT.
Joe, you happen to have one of the very few engines, or absolutely perfect setups that does not require a restrictor in the thermostat housing. Ive been racing a log time and have never been able to get a car, or have known anyone to get a car to run without overheating if there is no restrictor in the housing.
As for a debate, naah, It could go on forever. Everyone has an opinion, their own proof of how it works and so on.. I need to go load a new tune now and see if I can get my truck running right.

Every time I have increased the IC gpm the AIT's go down. Properly engineered systems do not cavitate. There probably is an extreme velocity that could be problematic, but no where near obtainable with a 12v automotive pump.

Hey guys I wanted to get some recommendations on what pump you guys my suggest for my water to air intercooler . I'm not looking for a cheap one but something quite that flows well and is durable . My car is a daily driver and I preferred quality. I was going to buy a kit from Frozenboost but the pumps look kinda cheap. Thank you in advance .

Thank you but they only have 3 models and the smallest is extremely big for my setup ( no room) and not to mention is over a grand. I believe for a daily driver the pump has to be better quality then just a race car , in a daily driver that pump will be ON longer in a week then probably the life of the typical 1/4 mile car .. I just want a reliable quite pump that flows well.
