Hello all i have 3 pump choices im looking for some feed back on. I will post some links if thats allowed if not i can take them down.

first is the zzp pump

second bosch pump

and last is davies craig

with the davies craig would i need the screen thing for it to work properly. the setup is going to have a small 3L tank since the car is going to be a daily with a heat exchanger i might add a ice tank later on in the trunk, im aiming for 500-600 hp.

 

I have the Davies Craig setup for the cooling system on my 4th gen Camaro, it works fantastic.
I'm also an using a Rule 2000 pump for my A2W system, it also works really well.
Don't think you could go wrong with either of those options.

 

Is the Rule pump a in tank setup? thanks

 

Yes sir it is.
Honestly, when putting around on the street I don't even turn it on and my IAT's stay low.
The stagnant water in the A2W cooler by itself is an incredible heat sink.

 

I'd look at a CWA50 or CWA100 pump.

 

Or even the CWA150, which is what I am using. It is small...and can be PWMed....

Ford Gt 500 13/14 had a PWM peirburg pump for 1-2 years and they are one of the best flow under pressure. They are German made and OEM for BMW which have electric cooling pumps. Any of the pumps Bosch, rule etc drop like a rock flow wise with any type of restriction. I’ve also run the Davis Craig brushless IC pump and that thing is tiny but flows good. You don’t want to run a water pump like a 35-55 GPH pump in an intercooler system as it Will generate a lot of back pressure and then kills its flow. The smaller pumps are designed for lower flow but higher pressures.

I have used alot of different pumps and currently use a Craig Davies pump. Honestly you can't go wrong with those pumps.as stated before you can pwm yhe pump to slow the flow so when you don't need it.

I've used the rule and they dont like contnuous duty.
zl1 pump is weak. Same as most stock intercooler pumps.
tried a moroso electric water pump and it didnt work well preobably for the previous posts reasons.
I have heard the gt500 pump blackbird mentioned is good but don't have personal experience.

 

What would you recommend for a replace for the rule pump?
Also what do you consider continuous duty, running for hours on end or only running when racing or dyno testing?

 

Related question for you guys, how fast do you want the water circulating? Would slower be better for more heat dissipation? Does fluid speed correlate to volume? I would guess you would want as much volume of water/coolant as you have the packaging space for?

 

The faster you can move a fluid, the more heat it can change.

 

Gracias!

I did some searching and found this, great read.

Supercharger Thermodynamics; Impacts of Coolant Flow Rate on Intake Air Temperature.

 

According to that article, I probably don't have enough pump...

Right? holy crap man, that was some graduate school level sh*t.

 

I drive my car alot or did. 150 miles a day and yes i would run the pump continuos. The craig davies pump was the best high flow continuos duty pump i have found. The rule would burn up once a month or so. Just my experience. Maybe its different for others. Better flow or whatever. I had never thought of just running the pump under boost at the time. Cars been dead awhile now and funds are holding me back from finishing it with the new build. All my info is probably 3 years old now.

 

Andrew,
What’s the cost of that?

Some of the factory cars use the Bosch pumps, my thinking is they use them because they are reliable, so I was going to use one of those. Some pumps need to be at the lowest point in order to pump the best, they are more of a circulating pump vs the ability to actually push water. Years ago I built an A/W system using a pump from RPS, cant remember the name, but it moved water pretty good, had a bleed plug which really made a diff getting the air out of the system. Be interesting to see what the guys on Drag Week use, but my guess is the pumps only run when racing.

 

Was the Rule pump you were using an in-tank pump?
Mine is in the reservoir so I would imagine that would greatly help combat high temp. issues.

 

the Stuart Warner pump will crush about anything, But you pay for it

 

I use a cwa400 on mine, mounted to bottom of 10gal reservoir tank, 30'+ of 16an hose, intercooler, chiller, return goes back in the bottom . return can push through all the water in the tank and still make a water mound in the tank.
you can pick them up clean off ebay for 100bux. they draw like 40amps wide open though lol. ive just got it connected to a manual pwm controller, it rarely sees over 50%
