Okay getting some results with temperature in the 70’s now. Pretty sure I saw Complete Street Performance going the 40’s & 30’s.. The bigger pump helps the flow but I am thinking of wrapping more hoses especially near the engine to help.

Had the car out for a 15 min cruise and let it idle for 10 mins then took the temperature on the cold line to Supercharger 73.2 F. I did read once in the 60’s.

Added a pic of the front grille and you can see the bigger PIERBURG CWA400 behind a custom grille I made. I decided to make 2 clips on the bottom of grille and 2 clips on the upper part so at the track I can just unclip the grille for better air flow into engine bay. Also I now have lower access to chiller and pump without taking off the front bumper.

You’re getting there…! Are you 100% on the refrigerant charge being spot on?

What are you doing with the car such that you need such low temps? Is your car a DD, digs, drags, track, or? Were you seeing a lot of negative advance or what?

I put that Pierburg on mine last month. Much greater flow rate.

That’s my next move after I wrap some more lines, the shop where I do the dyno recharged the system. What’s the coldest freon I can get? Will have to ask what they use. Anyone with a chiller no the correct charge weight of replacement Freon? They didn’t no the correct number and didn’t want to over fill and then cause the compressor problems. So what is the required charge weight, no idea?

Instructions:
Step 1.
The AC system does not require additional oil. If charging the car multiple times do not add more oil each time.
Step 2.
Vacuum the AC system for 30-45min (check that it is holding the vacuum) If it isn’t holding the vacuum you have a leak you need to tighten your AC connections.
Step 3.
Put in the charge weight provided.

The tune in the 800’s requires me to run either 98 octane or colder IAT’s to be safe as per tuner. I don’t have E85 in the area or I would have went a different route. I use meth for cooling and now a combination of chiller and higher octane. Car runs two tunes for strip and street.

Very nicely done BlackBeastSS2
Congrats!

What times did it run this year?

Zero times at the track, only Mexico so far. The plan is to have a few track days before the end of the season. I will post times then.

I'm not a car ac guy but 50 years in the commercial/residential end. To my knowledge 134a is the only refrigerant used in late models. The charge is probably in the owners manual but when you add something in the system like longer lines or h/e then you need to add more refrigerant to fill it enough. That would be determined same as engine tuning according to conditions. Pressures and temps should be the same as stock.

Nope, the Gen6 Camaros run R1234YF refrigerant not 134a. I’ve heard rumors that you can evacuate the system and run 134a in its place but haven’t tried it personally. I believe with an Interchiller there is a sight glass that you use to determine if the charge is correct.

Yes you’re correct about the sight glass, I forgot about that. I will watch the sight glass to see if there is any bubbles in the system. It’s behind my pull out grille, so coming in handy already. I need to see at a shop that specializes in AC to get there opinion if I can use a better/colder Freon.

Thanks for this guess my 2020 CC probably does too then. I need to check.

My Camaro came with 134a, I ordered new lines (just in case I messed up my supercharger install) and they came with R1234YF fittings. Exact same part number.. I just got ebay adapters and run 134a.... don't tell anybody but in the old days when we were dumb or smart? we would jucie R12 with propane (R-290) and lines were bent copper from the hardware store, don't smoke during an A/C leak... just saying. But it would blow frost out of the vents in Hawaii after being park in the sun all day as I was surfing...
