SL55/63/65/R230 AMG: Killer Chiller for 2004 SL600 (With SL65 engine)
(If not familiar with the term, this is a system which cools the intercooler fluid via the A/C system instead of just air flow; it typically cools below 50F regardless of outside temps.)
The company Beefcakeracing makes a Mercedes specific one and a Universal one.
It appears that 5+ years ago some people here installed a unit from Kincaid, but they went out of business and members here reviewed them very poorly.
Does anyone have experience with one of the Beefcakeracing ones or other brand?
I already have the higher volume intercooler pump installed and will install the M279 reservoir tank at the same time.
I do not want to go "crazy" and install a huge reservoir tank in the trunk for even better cooling.
I am considering eliminating the front starter battery and using the space for a modest reservoir tank. (Yes I understand the electronic CAN bus complexity of that.)
Thanks for any suggestions or experiences.
BTW the part number on my cooler appears to match the SL55, SL65 and SL600.
I see a couple threads and a YouTuber who mounted a Killer Chiller in their CL55; sure is a tight fit, likely tighter than on a CL65.
EDIT: Even though BeefCakeRacing lists the Killer Chiller, it is no longer made and I now have to research either the FI Interchiller or IC Chiller.

Is is part # A2205002503. I just checked and it is indeed connector to the high volume pump I installed.
