Heat Exchanger on SL55 AMG (Pic Inside)
Heat Exchanger and Johnson Pump are going on the car right now, as you can see it is not finished yet but will be soon and I'll make sure to show you how it looks with the bumper on. As you can see this thing is not tiny 
.
I'm running this HE with the original one so it will be extra cool.
Here is the Crappy Phone Pic

Very Nice!
I'm running a Renntech HE. It is amazing how you can sit in traffic with the water temp pushing 95 c and then as soon as some air flows across the extra HE, you can watch the gage drop 10 c. Get ready for ricer boys to see the HE and go "dude whatcha got in that thing."

I know the HE is exacly the same as yours. did you run yours along with the OEm one in the back?
Gotta look at that car feels way better
More MODS to come

Yes it is in line with the stock heat exchanger.
The 1st thing you need to do is swap the hoses going to your new heat exchanger so you don't end up with air pockets. Let gravity help your CM30 pump coolant.
The next thing you need to do is split the I/C coolant circuit from the Engine Coolant and add a reservoir up front for just the I/C circuit (or in the trunk, but i just added a small one up front).
Then, you need to wire up the CM30 to run when the engine runs utilizing a relay.
With these extra steps, you will see drastic improvements.
Lastly, i also installed 2 small Yamaha R6 Radiator fans on the backside of the new H/E. This way i can circulate air through it when not moving (sitting at light after getting of interstate, etc...)..
Maybe a little overkill though..

My RT (Renntech) HE is not set up in a separate loop. I can see how a separate loop could help IATs drastically. I think RTs theory is the engine is making more power and therefore more heat so it makes since to add to engine cooling as well. Is this an accurate statement or am I just full of hot water or maybe coolant

When it comes to modifying the intercooler circuit, aside from increasing the flow, the best gains are made from increasing the capacity of intercooler circuit's coolant, as well as increasing the surface area of your heat exchanger. By putting a large second heat exchanger, I increased the capacity of intercooler coolant and the surface area for the heat exchanger at the same time.
This way it takes much longer to heat soak your setup. And as we all know, HEAT SOAK IS THE ENEMY!!
Basically, i did alot of research on the forums, and found ALOT of different ideas for cooling mods, and when i found i had problems, i incorporated all the ideas into my car (2nd heat exchanger/separated circuits/johnson CM30 pump/ pump wired to run all the time/the fans(my own idea).
I ordered everything i needed, and fabricated what i had to. I still have the stock oil cooler in place, and was actually able to fit the heat exchanger and the two 6" fans in front of it. It is tight, but it all fits, and works perfectly. When i turn on my fans, i feel hot air blowing out of the vents in the engine underpan where the original oil cooler air was vented.
I drastically increased the performance of my car.
I don't know if i will ever do a pulley setup and a tune, but if i wanted to, i would certainly be setup for the extra heat problems that are associated with those mods.
Here's what i've done to my car, and why...
-Added a VERY large 2nd Heat Exchanger up front (26x7x2") and all the plumbing needed.
-Attached (2) 6" fans to the backside of the new large heat exchanger up front that are controlled by a switch hidden in the ashtray. I do notice a difference. It would take longer for the IAT's to drop once i got off the highway after a long pull, so i installed the fans. They help tremendously while i am sitting at redlights and moving slowly. They don't reduce the temps more than if i didn't have them, but they absolutely do reduce the recovery time it takes for the temps to drop back down after they rise
-Added a Johnson CM30 pump. (My stock pump crapped out on me and started my cooling revolution ). I wired the pump to run when the car runs so it is constantly circulating water.
- Separated the Cooling system from the intercooler circuit and installed a small reservoir to hold my IC water. It absolutely works. It keeps 200F degree coolant away from my 100 degree intercooler system. On the SL55, there is a bleed hose for the intercooler circuit that returns air and some coolant to the original coolant reservoir. When I 1st separated the systems, i didn't cap this return line, and after i ran the car, i noticed i had coolant boiling out of my new I/C reservoir
.
I also had about 5-10 F difference in temps after i capped this line and FULLY separated the systems. It was easy to do. Recovery time also decreased with this mod because hot engine coolant isn't fed into the system while driving. I found a BMW power steering reservoir, fabricated a bracket for it, bought some hose clamps, and installed a couple of splices. It was easy to do.
These cars should have come with a separate reservoir from the factory. The separated circuit is a better and more efficient setup..
- Installed a PTE thermostat to keep engine temps LOW.
I had a bad IC pump and really didn't know it until i started paying attention (the car ran out of power on HOT days). Then when i installed my ScanGauge II i was watching my IAT's in the high 190's i knew immediately...

The bad IC pump your referring to that isn't the SC pump is it? which one are you referring too?

Nice write up NikleinR6, thanks. Lots of useful information. I thought I was pretty much done with mods, but it sounds like a few tweaks to what I have could make a significant improvement.

If we were relocating our intercooler reservoirs to the trunk, I would suggest the extra flow from something like a Cm90 (to pump coolant to the rear of the vehicle and back up to the engine).
But for our setup, the Cm30 is optimal.
Some argue that a Cm90 could flow too quickly and heat exchange wouldn't occur (Coolant doesn't stay in the heat exchanger long enough).

NikleinR6 can you outline the flow of your system? I'm going to be mirroring yours except using a trunk mount tank but retaining the stock heat exchanger plus an aftermarket unit. Do you go from tank-pump-factory IC-aftermarket IC-supercharger-tank? Appreciate any advice.

The BMW reservoir is basically a "fill point" for you to add fluid if necessary.
The coolant circulates below it.
Its a closed loop system, but you have to have a fill point.
Therefore the size of the reservoir is irrelevant.

Seems great for cooling the air, (and I'm all for that) but now isn't the oil cooler getting heated air from being behind the new HE? 
Anyone have any theories on this?
