Split IC circuit or not?

I've been doing a ton of research lately on this subject and I'm not still not fully convinced that it needs to be split. Could I please hear from both modded and stock 55's that has done this mod, both rear and engine compartment mounted reservoirs.

splitting the circuit helps, period...but as you know it's not anything close to a fix. the ONLY reason to have an engine mounted reservoir is to give yourself a method of filling the i/c circuit after splitting the systems. there is no circulation going to the bottle, or enough capacity in the bottle even if there was, to make a difference. a trunk mounted reservoir adds enough capacity to make a decent difference but it still cannot overcome the limitations of our inefficient i/c cores.

chiromikey is right but check out my comments in this thread:

https://mbworld.org/forums/w211-amg/...tting-i-c.html

The real way to do it is to use a large reservoir (difficult to fit in our cars) and put the coolant in the reservoir in active flow in the HE system. Otherwise, the reservoir will act only as a fill point and is a bit of a waste of time as it does not increase system capacity.

Thanks for the reply guys. By chance, is there another thread somewhere explaining in lames-man terms of exactly how this ideal system would work? I've talked to my tech and he's down to try anything, he just needs a little more clarification on how the trunk mounted system would work. I don't plan on adding on anymore power then what I have but wouldn't mind making things more efficient. Any help would be appreciated.

If you spend some time searching you will turn up some pretty trick installations. My rule of thumb was that after doing a massive HE and Johnson pump, I would do a trunk mounted reservoir if I ever lost power from heat soak or had SC shutdown again. So far that hasn't happened so I stopped worrying about it and turned my attention to other projects. Also, doing a large trunk mounted res, dual pumps, and all the plumbing puts plenty of holes in the car that prevent a full return to stock so that may be something to consider.

Code 3 was supposed to be working a custom setup that would fit in the engine bay but I am not sure where they are on that.

Thanks. It's winter time anyways, I'll wait to see what happens with Code3.

i HIGHLY doubt anyone is going to fit a reservoir that will have enough capacity to make a difference in cooling efficiency to fit in our engine bays. a properly mounted trunk reservoir will only put two holes in your trunk that can easily be patched and never seen if you want to return it to stock. you can search some of my posts for pics and and info on my system.

imho, it's only worth the trouble if you're planning on several trips down the 1/4mile or do a lot of high speed runs. if not, just add a larger or piggyback h/e and new pump (oem or aftermarket) and call it a day.

i posted some info and pics when i first had mine made but it was a while ago. i'm sure if you searched key words or frases like "reservoir", "heat exchanger", "trunk mount", etc that you'll find plenty of threads.

I agree with this 100% A trunk reservoir is for the extream hard core race guys. Spliting the system helps alot for DD. Add a heat exchanger and pump split the circuit and call it a day. Unless you are gonna turn into a 1/4 freak?

i am seriously considering the trunk mount.... after having it do you feel its worth it over just the new HE and pump?


btw, i love the 1/4 mile

I'm convinced now that it's probably worth while to do the trunk mount versus the engine mount. I've been researching this for the past couple of days now and after speaking with my tech today we decided to do the trunk mount. It won't be as fancy as Chiromikeys setup (the extra HE and 2 cooling fans...BTW bad azz setup) but it will have a equivalent size reservoir.

Chiromikey, where did you get the reservoir from? I would also run a extra pump just like yourself. It may be overkill but that's just me and plus it couldn't hurt.

Rocketw19, I probably won't be a 1/4 mile freak but it is fun and I'm sure I'll be doing more then a few times a year. Is there a big difference in labor between the engine mount and trunk mount?

i was experimenting to see how far our limited i/c core could go. if i had to do it all over again i'd skip the rear mount h/e but probably do the reservoir. actually if i had to do it over again, i'd have spent money on fabbing a new i/c set up instead of waiting on all the tuners to come out with their severely over priced set ups!

the reservoir was custom made by chris at floored fab. for the length of lines to run the trunk mount i don't think the extra pump is overkill at all and would highly recommend it.

Splitting the systems?

Bassn_07 : I believe that chriomikey is on the Right Track. There is a Need for a larger Condenser cooling core on the outlet side of the Blower. Code 3 was working on something like the DTM unit. But seems to have run into some delays. Top Mounted SLR types would work well too. But Major Dollars and are hand built also. If I remember right Rflow306 would use 2 10Lbs of ice every 1/4 mile run he did at MIR ,1 year ago. It was a 90* plus day. I sware he brought 10 bags of Ice & we used them all. I posted an opinion. over on the R-230 threads. Please remember it is only a opinion https://mbworld.org/forums/sl55-amg-...ml#post3234069
