[QUOTE="MalcolmV8, post: 15546229, member: 8854"] No one single answer to the KC setup, a combo of problems. One been the car has custom cams and idle had been temperamental and "sensitive" if you will. Every time you have the a/c kicking on or off it would upset the RPMs a bit and then re-settle in. Annoying. I also like a clean engine bay and the abundance of hoses is not for me. Plus they're all wrapped in heat shielding so they're big and bulky. A bigger issue was my a/c constantly giving me issues. I can't say if it was the burden of the killer chiller or just unrelated. I ended up swapping out the compression, the condenser, the lines and tried multiple orifice tubes of different sizes that would adjust the cooling rate between cabin and KC. I tried 50/50 split, mostly KC and even mostly cabin just to see. In the end my a/c was just not working like it used to I don't think. I tried regular R134a and the industrial R134a replacements as well as experimenting with pressures slightly out of spec but that only made things worse. Even looking back at data logs the KC did help but really doesn't solve the problem. It gets your IAT2 temps down a lot in idle and normal cruise but WOT they climb very quickly because it simply can't keep up. Do multiple WOT pulls and they temps get really crazy high. It pulls down after a few minutes of driving but when you analyze that what good is that? Great temps when you don't really need them? Not to mention running the a/c that hard pulling so much heat was really heating up my radiator and caused engine temps to run a good noticeable amount hotter. They were definitely better than pre killer chiller days but it left a lot to be desired. So rather than continuing to replace parts and keep working at the a/c just to get back to subpar results I decided to go a whole different route. [/QUOTE]
