Is there a split cooling/trunk tank kit out there?

I am thinking to do this ... also, would an ugpraded EC HE and Bosch 010 pump combo help as well?

So the setup would be: EC HE, Bosch 010 IC pump, split cooling with trunk tank.

How difficult is it to split it?

 

Speak to these guys they can build you one

http://dadscustomintercoolertank.com/

Have 2 pumps

Trunk tank to trunk mounted pump
Trunk mounted pump to SC
SC to front pump
Front pump to Heat Exchanger
Heat Exchanger to Tank

 

And that'll keep IATs very low (120' or less after WOT runs) with that trunk tank/split and EC HE and Bosch pump setup?

Anything adverse about doing this?

 

You have two pumps to worry about...

 

It will be a lot of work trust me, especially if u want a clean set up.

 

No idea why you would run two pumps...One will suffice.

 

I honestly don't think a trunk tank/split cooling is necessary unless, a) you live in Southern AZ or South Florida where it's humid almost through the year and temps of 90*+ are likely most of the year, or b) you're running wagon wheel pulley/track car and producing TONS of heat, or lastly, c) both of those.

A regular, DD commuter car should have enough with a large capacity HE and the Bosch pump with the occasional spirited runs here and there and enough time for recovery. This is my setup and I have ZERO issues with heatsoak. A trunk tank would be overkill for me, personally.


Just my .02

 

because there is about 40ft of hose u have to run from the trunk to front and back. mine has a pump built inside.

 

I live in London which rarely gets above 80F and a trunk tank makes a huge difference. I fitted it when I had a 176mm crank pulley and already had a EC heat exchanger, I gained 4mph trap speed on a 1/4 and the most important thing is how consitent the power is.

It does of course always come down to personal choice, fitting the thing is a long job.

 

For me adding the second pump was an easy choice, considering the job as a whole adding in a 2nd pump in the tank is a 30 minute job and adds additional safety should one fail without huge cost.

I went with 2 x Bosch 10 pumps

nice ! I think everyone should do a trunk tank

 

Ur mods r sick bro, what dont u have? lol Did ur trap times get better too ? That trunk tank seems like a lot of work to run a clean setup and not to mention the incovenience of not having trunk space. This is why many people may be reluctant.

 

why not do a killer chiller?

 

Cheers, I only started wanting it to have a little more power and deeper exhaust but got carried away.

On a W211 the trunk tank fits in the space of the spare wheel and is hidden under the trunk floor so no one can see it and no loss of space.
Many didn't come with a spare wheel anyway just a small compressor and a can of tyre foam for emergencies.

 

Split system is a must for pretty much anyone on this site (an enthusiast). You can do a small reservoir like I have, do a larger engine bay tank (like dad's makes), or do a larger trunk tank (3 - 5 gallons). I will be moving to a rear tank and will share data on IATs of stock vs. small reservoir vs. larger rear tank.

 

so long story short, no one makes a kit with everything included for install?

I'm in texas, heat is ALWAYS an issue, no matter the car!

 

Yes there are several...some are junk.

EC is in your state and can set you up with one or BIP or BPI (something like that in GA.) had a group buy.

Basically you have a tank and some lines...some say you need another pump, but you don't as the Bosch 010 is very good and has ample power to push the water through the system.

 

I will be at the track hopefully next weekend, I will bypass my 2nd pump and log some data and let you now how it gets on. It will be interesting to see if there is a difference with 1 or 2 pumps.

 

There won't be any difference as both pumps have the same flow rate ....

 

what size is your Cobra tank and where did you mount it ? I used a Fabtech 2.5 gallon tank mounts very easily under the hood and is sealed off from engine bay heat. Have had issues with the lid leaking though even after getting a new lid from them.... Other than that it is a nicely built piece.

 

The cobra reservoir is ~ 1 qt. and I have it mounted left of center (passenger side) up front near the radiator fan shroud.

I was one of the first with the Fabtech engine bay tank (Dad's Intercooler Tanks), but was not happy with the fit (the mounting tabs were reversed), required me to remove the rain gutter, and the cabin filter was junk IMHO. That said, dad's / Donny makes great tanks and I had spoken to him before Steve put together his "kit"....When I get a rear tank I will order from Donny http://dadscustomintercoolertank.com/ ....I believe he is no longer making tanks for Fabtech, but I may be mistaken.

 

With a trunk tank expect IAT's to drop about 20-30F after a WOT blast from stock, avg cruising temps are about 15-20F above ambient. That is with an upgraded heat exchanger and two pumps mind you.

Recovery time is much improved and you will have the ability to add ice to the tank should you decide to take it to the track etc.

I'm a data-logging *****, but results may vary...

 

Has anyone logged the difference between water temp in circuit and the intake temperature? Is it constant variable or does it change? Example water temp is 90 degrees and intake air temp is 120= 30 degree difference.

 

Not sure, but I thought that I read that replacing the silicone under the cap would help eliminate the leak https://mbworld.org/forums/w211-amg/...s-results.html call Donny! some guys don'tlike the frozenboost HE as you must relocate oil cooler...but everyone should do what they want and research first!(inlet outlet diameters flow etc...) here is the diy for Frozenboost HE and oil cooler https://mbworld.org/forums/w211-amg/...r-upgrade.html
