Cooling Solutions for your C63, by Dime Racing
One major concern we always see when testing the C63 is rising intake air temperatures during acceleration. Temperatures rise far beyond ambient temperatures creating very inconsistent power levels.
To make matters worse, the factory design of the cooling system interconnects the cooling system for the intercoolers and the cooling system of the transmission. As transmission temperatures start to increase, so do your intake air temperatures. We have fixed this problem.
We have effectively tripled the cooling capacity by means of a high density heat exchanger that is double the thickness of that from the factory. We have also separated or divorced the intercooler circuit from the transmission cooling circuit. Intake air temperatures are no longer affected by transmission temperatures, and you feel consistent results weather on the street or track.

Does the divorced system present any problem related to possible leaks in one system and an undetected overheat????
The transmission cooling circuit also has a thermostat that is maintained. This is in place from the factory to bring the transmission fluid temperatures to operating temps as quick as possible. Removing this would lose the OEM drivability of the car.
We hope this helps. Thanks again.

I appreciate what looks like a very nice system in some aspects, but if you've added capacity and a larger intercooler, I am concerned about what could be construed as some very obvious drawbacks and weaknesses that aren't covered in your launch detail...
Don't want to be a naysayer, but I figure we get this covered and you can respond to this so we have the data and folks make informed decisions.
I've been through this in another vendor's forum with a similar system that addressed all of these issues to an amazing level....
Thanks!

I sent a PM a couple of days ago, no response was received.
auditoamg asked very pertinent questions but he got ignored.
That says a whole lot about this company. I would rather wait for Weistec's cooling package or go with the Eurocharged one for less than a $1000.

Still no PM and still no answers to these questions:
We remove the small transmission heat exchanger, and add a large oil to air cooler in front of the car. Please see our schematic below.
There is no fluid level sensor in the intercooler coolant system. The system is constantly monitored via intake air temperature sensors (one sensor in each bank). This is also the case with the transmission. Fluid is filling via the oil pan and temps are monitored via the TCU, internally. There is no fluid level sensor on the transmission as well.
Please let us know if this answers your question a bit more. Thanks again.

1) This isn't a true divorced system. You aren't separating our two systems that were normally coupled together in the sense that they are now completely different flow paths. Your original statement was extremely misleading unless I've missed something. You've just shortened the turbo intercooler path so it's not also cooling transmission oil.
2) Your explanation leads us to believe there is actually no OEM coolant temp sensor anywhere in that vehicle. If this was the case, our main dashboard cluster display would be only an IAT gauge, which is false... So where is the OEM coolant temp sensor located?
3) you've added an oil to air cooler for the transmission, but what's driving/pumping the oil through this new, larger system, or is the new exchanger not placing more load on the existing system?
Can you provide that data to prove no additional load on the systems?. As you haven't added any additional pumping too a system that claims larger capacity, the system should see increased load. We don't want increased failure rates of critical systems in a mod designed to reduce such an issue from heat.
Thx.

There are a few other vendors with solutions for this platform that are even less than that, factoring in a boost pump, without the transmission oil solution. Not apples to apples, but still...
So help us out.
The quality isn't necessarily in question... Yet.
Your C63 has a few systems. One of these is the engine cooling system, and another completely separate system is the turbocharger cooling system. These systems however have no relation to each other. The engine cooling system does have a temperature sensor, and this reading is displayed on your dash board. The Intercooler cooling system does not have a fluid temperature sensor. It only measures the temperature of the air that it is cooling.
Intake air temperatures are not displayed on the dash board. If you were to purchase a data logging tool, you can most likely view Bank 1 and Bank 2 IAT's via the OBD data logging tool.
We would be happy to send you more literature and discuss more in detail if you would like. Just give us a call or email any time. Thanks again!

This system is priced at this point because we have implemented some of the most efficient radiator core designs, billet aluminum end tank construction, OEM fitment, and far more components than any other system out there.
The result is 100% plug and play. No hose clamps or zip ties needed because we took the time to design quality components that we trust on the race track.
We will be posting third party unbiased results shortly. Thanks again!

But my questions remain:
The new exchangers are larger, so do they place additional load on the existing pumps that might result in reduced efficiencies and a failure? That includes the air/oil exchanger. Do you have testing and data to show this?. What justifies this very high price without any boost pumps to increase capacity?

The two intercooler circulation pumps are pulse width modulated and very efficient from the factory. These can actually be adjusted via tuning to increase or decrease flow based on many variables.
The transmission cooling since it is own separate system now, uses the transmission fluid pump as it source of flow. The same exact way it is done on the C63 Black Series as an example.
Thanks again.

I'm not interested in tuning the car to increase the flow of the pumps. I live in a hot climate, so my interest is simply to keep IAT and engine temps down... Because on this new hot-insideV design, the turbo heat will soak the engine and vice versa.
We need data, period.
Thx.
Also, I should buy a data logging tool to see the temp differences....
NOTE: Auditoamg has some very valid points. Above comment towards the 3 post wonder.
