Car gets hot with a/c on

[.rampage.]

I am stumped my car gets hot with the a/c I just supercharged it not a problem before....I installed a koyo tt 3 row supra radiator 160 thermostat 2 zirgo 14in fans with a shroud...ok so I can drive about 20-30 mins and it will start to overheat and get a ck eng light for knock sensor no 2....the car operates normal without a/c on. I noticed the car warm up a lot quicker with the supercharger no oil in coolant or white smoke. Any ideas are appreciated
I checked a/c pressures low 35psi/ high 250-260 the car does not idle up when I turn the a/c on

what have you done about fuel and ignition after supercharging?

Sard adjustable reg one step colder plugs and going to put mu apexi safc back on ...I had 440cc injectors in but way to rich ran

i'd say it's a tune issue, how much boost?

6 psi max it's a low boost setup

Wonder when it sends the knock signal if it retards the timing making it hot prolly running lean right now with the extra strain of ac and heating it up just ordered a Afr wideband been previously just dyno tuning but that was with 440cc injectors took them out cause of how rich it was leaned would only go 10 to1 now with stock injectors

good way to kill a motor guessing at a tune

was getting it tuned so i didnt kill the motor with the safc

SAFC is still guessing at a tune in my opinion, add that to the fact most stock ecu's are getting a little flaky, I highly suggest you get a stand alone ecu.

What would be your recommendation

find a tuner in your area that has a good rep of not blowing car's up and see what they suggest, I run a Motec M800 on one car and a Wolf V4+ on the other.
