Renntech intercooler upgrade?
Any of you have this? I love the Biturbo engine and the power and torque it provides but I always wonder if the engine is actually running at peak performance since the stock intercoolers are such crap and prone to heat soak. I live in South Florida and it is hot and humid on a regular basis. What do you all think? Is it worth 3K to be assured the car will always have the power it is suppose to have?

RennTech IC
I was contemplating the same issue with my CL600. However, the contemplation is now over and I will be doing this mod on Tuesday. I think that the knowledge of having peak performance reliably-time after time--is worth the relatively small percentage of the cost of the car.
It's become a no-brainer. I am in LA and while we don't have humidity, it can get hot. This week it was over 100 most days and the performance of the car did suffer. No more.

I don't have a V12 Mercedes.
A good friend of mine has an SL600 with the RENNtech ECU change, as well as many forum members. They all love with with only one exception so far. For the tremendous torque and horsepower gains, I think it's almost a no brainer, especially if you can get a dealer to knock off a few hundred bucks (since you'd also be getting the RENNtech IC installed as well).

However, E55Jay has run series of tests that confirmed if the IATs are too high, the ECU will decrease the level of boost; thus decreasing the performance of the car itself.

The air bubble frequent occurrence is mainly caused by a flaw of the intercooler system especially for the earlier 600 chassis.

The gain from the Evotech/Renntech ECU upgrade is close to being 100 rwhp and 130 rwtq. (for 600 engines) If the intercooler system is not functioning properly, the car performance will decrease significantly regardless of any tuning done to it.

Yes I am! I'm also selling the car if anyone is interested.
