Interest check for those want to divorce the HE coolant loop with simple reservoir

[lowjonathan]

Just to check out interest for those who want to divorced the HE coolant loop from the cooling system.

have spoken to manufacturer, he mention he do need some numbers to keep the cost down for everyone.

The kit will be a simple reservoir with some piping and bracket.

Target price $100

the small black reservoir will be something like page 13/14

**those who need the HE combo kit (HE+alum tank) for AZ member special buy is still on going...PM me for his email

[waxxonMTL]

i would be interesting as I got a PLM kit myself. 100$ seems a bit step tho for rubber hose no ?

i am trying to get the number of interest so it can be get going.

especially for us on PLM kit.

[points]

I'd be interested at that price

Any feedback you can give on the PLM? Any significant gains?

[Pyromatic177]

Can someone please explain what this will do? Cause for $100 I'd be interested

This is intended to separate the coolant circuit that cools the engine from the coolant that cools the supercharger. This is what they called "divorcing". To make this happen, the supercharger needs it own coolant circuit/loop and reservoir. The $100 gets you the hoses, reservoir, brackets to divorce the systems.

[tars9]

Interested. Would need to comply with b8 with PLM and ADS.

Thanks. Can this work with the stock system? For now anyway.

Yes.

I would be interested, if the reservoir is larger than the current one I run on my APR system. BTW, you are also going to need a silicon bypass nipple for one of the pipes at the reservoir, regular rubber bypass nipple will not work. They start cracking right away.

[Jflow23]

Definitely interested...been posing this question for a while. Lowjonathan, thanks for reaching out to PLM...I hope they elect to take on this project.

So u refering to the bigger square reservoir on PLM combo kit now?
https://www.privatelabelmfg.com/heat...-reservoir.htm

reaching out to get smaller one as APR current
which Jflow23 has did up his own small reservoir. He is running divorced HE Coolant loop for sometime using his custom HE.

thanks

[rcaro900ss]

No, that is not the reservoir on the PLM site. I am looking at the overflow/fill reservoir on page 13 of the APR information. I wanted something larger that what I already have.

[lowjonathan]

i see, maybe i can let PLM guys know to make it bigger.
do u have any idea what is your current one capacity?

tks

[jran76]

I think you guys will find what most others have.... Just divorcing the system does very little. There is only one location where they meet, and that's at the overflow tank. Otherwise they are two separate loops already. So, the only chance for the two systems to exchange fluid is when there is overflow; even then it would be a very small amount.

The downside is once you divorce the system (disconnect the S/C loop from the overflow tank), you will loose the ability to know if there is a leak on the S/C loop which can be an important thing to know for several reasons (a leaky intercooler can destroy an engine, and running out of coolant can destroy a S/C). I'm actually surprised APR and AWE still offer this as an option (although, I'm going to guess the new APR system will not).

A local owner recently divorced his system, and found no discernible difference with or without it divorced. I think this was one of those things that sounded like a good idea based on how other platforms benefitted, but once you really dig down into it, this particular platform essentially has a divorced system already.

Did the guy with the divorced system change anything else? Would a larger reservoir help add more cooling capacity more than the divorced system?

No, he already had the AMS/Alpha coolant system (heat exchanger, pump, res).

A larger reservoir absolutely makes a big difference. It greatly expands the thermal capacity of the system. In order of impact, a larger core/radiator/heat exchanger makes the biggest difference, then a large reservoir, then a pump, and then divorcing the system. I think most of the guys here have a larger heat exchanger and reservoir (that is essentially what the PLM system includes). PLM, APR, and AMS/Alpha include a larger reservoir. Revo, AWE, and Forge do not.

[jran76]

And, to be clear.... Divorcing the system does do something; just very little. Maybe a one or two degree drop at the most. To me at least, the potential downsides (cost, monitoring coolant loss, etc.) is not worth that. For some people, it might be I suppose. Without a doubt, heat is the enemy of performance more so on this platform than most, and the dual pulley cars need all the help they can get.

[cspcrx]

I am with you that is why I went with the AMS system. I DD my car and not knowing there is a problem before something happens is not acceptable for such a minor potential gain.

the reservoir of the plm look bigger than other, so that might be a good thing.

thanks for the explanation ! I guess i will stay undivorced then.

AWE has an add-in RES, granted it is not huge.

[jran76]

I think that reservoir functions more as an expansion tank for the S/C loop than it does a lot of added capacity. There's is a neat concept, but quite a bit smaller than the others.

[Hofahome]

I'd be interested since I am not happy with the fit and finish of my solution. However I would want it to hold about a pint though.

[lowjonathan]

tks alot to jran76 for sharing the pro and con of divorcing the SC loop.
it is more for the PLM users with already have the bigger square reservoir come with the combo kit.
over at the other side "AR", one of the divorced user commenting the both loop coolant temperature difference as much as 35F durig tracking.

jflow23 has make his own small reservoir and notice his custom HE is cooler.

Just to share for the coolant checklight to light up, the plastic tank coolant level is way below min level.

tks

[infinkc]

When i was thinking of divorcing the system, i wanted to go something OEM looking. I wonder what tank APR used on the stage 3 kit.


i also thought of using a tank similar to this:


Helps monitor the coolant level if its clear.

Ummm, no no and more no. You can lose all the coolant in the supercharger IC system and you absolutely will not destroy the supercharger. There are a ton of non-IC supercharged systems out there and it doesn't kill any Eaton blowers whatsoever. All that is used for is to lower the IAT and allow for higher ignition timing (less retard) to be run to make more reliable power. You may however burn out the water pump that's used in that system, but I want to say that the ECU may detect that and shut it down to keep it form burning out if it's not pumping fluid and just air. I'll need to look at the pdf to be sure though and I'm too lazy to do that at the moment.. Aside from that, the engine is also safe from destruction, although there's a very good change the ECU will retard timing and boost so much based on its safety parameters that you simply won't make any power and should feel the car not pulling as strong. Other than that, that's about it.

It can absolutely destroy an engine by dumping coolant into the heads. I've personally seen horrible misfires from it, and had an Audi tech tell me they've seen an engine failure when the cylinder did not fully deactivate. There was also the one reported below, and the one refrenced in the below thread on AR. But hey, maybe they're all lying, and you're right.... And, I'm sure coolant leaking in the S/C is good for it too.

No kidding, but dumping coolant into the engine due to a faulty IC core INSIDE the supercharger housing IS NOT what you were talking about or leading people to believe with what you were saying before. I can assure you that cracking an IC core within the housing and dumping fluid into the engine cylinders can happen regardless of the system being divorced or not and it makes no difference at that point. The fact remains that the IC system losing coolant will happen mostly from the failure of the external heat exchanger in front of the radiator being damaged. That's where your leaks will happen almost all of the time and that is where you will lose your coolant and not know about it if you were divorced. Hell, even if married, you'd still lose coolant that way, so what I said is still 100% correct, which is, losing coolant in the IC loop WILL NOT cause you to destroy and engine or supercharger simply because it all leaked out because your system was divorced and you didn't know it all drained out.

What are you talking about? I am specifically referencing a leaky I/C inside the S/C. If that wasn't clear, sorry (you did highlight that part in bold red print....). Having a low coolant indication has allowed several people to identify that issue before it became a bigger problem. I'd hope it's pretty obvious to any knowledgeable person that losing coolant in the loop would not destroy anything but IAT's. Ha. I didn't even think that'd need to be pointed out....

[jran76]

I don't want to derail this thread any further, so I'll leave it at the above. Apologies to the OP, and if I over dramatized any potential problems. At the end of the day, there is only a very small performance benefit, and that was really the point. Anything beyond that you can take as you want. Obviously, a lot of people have divorced the systems without issue. If you pay attention to IAT's, misfires or whatever else, you should be ok.

[Jflow23]

Anybody find another alternative? I was really hoping this was going to happen.

[acsgp]

If you divorce the systems, don't you need an additional pump for the 2nd loop?

[Jflow23]

No...the electric pump runs the supercharger loop, the engine coolant pump is mechanical. The two loops are connected at the main expansion tank...easily divorced.

[SPONGE]

Update on this divorce setup.

[mrb5_supra_wrx]

Any more info on this want to divorce my cooling system but not seeing much info in it or a proper way to do so

See where the rubber cap is, middle left? That's the main coolant loop, and where it is capped in that picture there is normally a hose that runs down to a T in the SC coolant loop by the pump. I ended up running a hose up to a small overflow tank. This post might be helpful.

Anyone try this one yet?

This would work fine, only issue with this one is that it functions just as an overflow reservoir rather than an actual functional increase in thermal mass. You'd need a tank with an inlet and an outlet hose to get that affect. Not really worth doing IMO unless you're actually increasing your cooling capacity.
