SL55/63/65/R230 AMG: KC Install on SL55 Experience?
Where have others installed the KC heat exchanger (R134/IC coolant)? - I located an install video using room where the SL's start battery is located (so that won't work)
The split cooling kit (with the BMW reservoir) doesn't add much capacity to the IC loop - have others installed a larger under hood reservoir? I'm not sure what size would fit, or if one would be required to just make a couple pulls (I was thinking a gallon, or so).
Personally I won't mess with the chiller system unless your really into tracking(not sure why you'd choose this car) or dragging it multiple nights through out the year. If your looking to just go to the the drag track once or twice a year for fun, split cooling will probably do just fine for you and you can spend that money on other go fast parts.
Splitting the system includes installing a separate reservoir, and the kits come with a BMW P/S reservoir that isn’t very large. My thought was to install a somewhat larger reservoir in case I later install a KC.
I plan to install a 77/76 mm SC pulley (with tune) and do not want this performance to be “washed out” by IAT / soak back.
i don’t plan to install an air / IC coolant heat exchanger or large remote coolant tank - I’d rather install a KC.
With any luck, I my IATs won’t need to be further chilled (for my use), my main thought was to install a larger reservoir when I split the systems (not to want a larger reservoir later, if I installed a KC)
If the resulting temps are too high for full performance I will install a KC.
At WOT A/C is turned off (no chill), I’d like my reservoir to be “right sized” to have a large enough capacity for my needs - but no more (recovery, size, weight).
I guess I can start with the “BMW” tank and increase if required - if need be. I could also determine the flow rate and then size for the desired flow of cold fluid.
There doesn’t seem to be much room under the hood. I could mount the KC low near the IC pump (I guess, I haven’t looked).
