We have hit a hurdle and where else to turn to but the experts. After the install of my larger intercooler, heat exchanger and trunk mounted reservoir, my IATS are way high at 176*.

We have not been able to tune the car as a result but I do have a few questions for guys with trunk mounted reservoirs. My setup only has one Meziere pump in the stock location which is pumping the whole split cooling system, here is a vid of the trunk mount water flow:



I am thinking one of three things:

1) A massive bubble in the system somewhere
2) Meziere is pumping the water to fast to cool it
3) One pump is not enough, pumping the system too slow

Could those with a trunk mount reveal their system

The flow does not seem bad at all from that video, so I would think that an air picket may be your problem. I see bubbles in the water.

Hopefully Brooke or Shardul can chime in, but I was under the impression that an in-tank pump should be used, or at least a separate pump should be put in supplemental to the one at the front of the car.

Chawkins, Looks like you might have airpockets in the lines or intercoolers. Have you tried bleeding the entire system? If pump is working and water is circulating I can only see air in the system as a probable cause.

I am starting to think that one pump upfront it not enough as the stock cooling with the meziere gave better iats. When we added all the heavy duty components and tried to tune the car, the iats were sky high almost resembling a failing pump scenario.

i have a intank pump in my reservoir. So here is the flow in the system: Front H/E to rear tank to intank pump to meziere pump to S/C.
This flow setup works since after a run at the texas mile the fluid was still cool

You need another pump at the reservoir.

That is all my brother!!

You ran this weekend?

no this was from last october after seeing Exotic-metal55 cars

Will an external cm30 work or does it have to be an internal reservoir pump? What internal pump you using shardul?

So If im correct, You guys are basically saying the pump is sucking the water so fast it is taking in air? and the other pump would in turn feed the Meizzere?

Rule2000 bilge pump. I will post a pic in a bit so you all can see.

chawkins2001

Is it an automatic or non automatic version, there are two.

chawkins2001

I guess part# would be shweet. There is also the 53s 2000 pump???

loungn14

we all have the same system, and ya its awesome...

after runs, you can easliy stick your hand in the rear tank and the water is cool.

Rule2000 bilge pump ftw!

Also, check that none of the lines are kinked, as they can trap air that way as well, and use the best lines that you can get.

chawkins2001

What type of rule2000 bilge is it, the automatic, non automatic, 53S???? Shoot me a part number or link of the exact pump homies

BTW the pump will not fit in the tank you have. double check the measurements of tank and the pump

5.2" high, 8.5" width, 13.5" length, circumference opening is 5.5"

Correct. The pump doesn't have enough head for it to work properly. It's most likely cavitating.
That bilge pump would do the trick.

loungn14

I just measured mine for ya and the Rule pump itself is

6" x 4 1/4" x 4 1/4", so do another inline like a cm30 etc...

your tank is not high enough to fit the Rule2000 bilge pump. Check the Rule website to see if they make anything smaller. But remember the outlet on the inside of the tank will have to male pipe coming out so the outlet of the intank pump can be connected to it.

BTW I have new a extra tank sitting around like the one in my prevous post if you want to buy it. all you would need is a bilge pump.

I am with the guy who said air bubbles. DAMN, it's like you are blowing bubbles out of there. Mine just looks like the water is bumpy with zero air as it flows.

Before major surgery, at least work on trying to get the system bled. All that being said, I have 2 pumps as well. No bilge though. Most early systems had one Johnson pushing front and one Johnson in the front pushing back.

chawkins2001

I have settled on a cm30 back there for the interim as there is one in the shop. Since my tank is not as big as others, I am going to order another meziere WP136S and stick it back there for the long run.

chawkins2001

We added the cm30 back there, and it increased the flow tremendously, however, the Meziere pump upfront was making a very audible humming noise. How loud are the meziere's, because when it was pumping on its own, it was dead quiet. Anyone have a sound clip of their meziere upfront pumping?
