Challenger Hellcat A/C help

I’d charge low side to 50, 55 tops in hot weather hot coolant on the suction side with chiller and cabin going.
Do you have a sight glass to check for bubbling? You should see solid liquid.

Yes i have a sight glass. Solid liquid noted

Axcuse meez, butt just ware is da Jonesburow cum paired 2 Chattanooger? A sight glass is purrfect. 2 sea if da frigerant is dare. 2 dew sew you'll self doe. Youz have 2 have da 2 fittens, solder, cleaner, silva soldea, sight glass, and da B tank. Good job and a perrfect setter upster.

Hopefully you get it figured out

Which aux tank are you running? Humidity has been bad, 40-50 degrees IC coolant temp is what the “real world” is on these things unfortunately. If you have a BMR tank, ditch it and get a bumper tank. The BMR tank basically sits on top of the header

I have a bumper tank from Glenn at RPM. I dont think theyre for sale yet. 4 gallon capacity. Humidity here has been 60-70%

And you’re running a CWA400 pump now where you weren’t before, is that right?

Correct, before i was running stock pump. Now im on a cwa 400

 

[Unholy707]

Are you bypassing your heat exchangers? Did you plump the cwa any differently than the stock pump?

 

[Demid22]

Heat exchangers have been removed.
Previously i still had the little on by the drivers front tire, but now even that one is gone.

Plumbing is as follows:

Whipple->tank->pump->chiller->Whipple

 

[Demid22]

Whats blowing my mind is with chiller and cab in it gets down to 60 degrees or so. But when flipped to just chiller it only drops another 5...maybe 10 degrees at best

 

[Unholy707]

I wonder how much heat that cwa is generating, flowing fluid a lot faster in a short circuit than with the stock pump. Have me stumped here

Yea me too. Glenn with RPM who built the tank has my exact setup, whipple and all and is seeing 30 degrees on his intercooler in 95 degree weather.

My opinion, and the way my plumbing is; Hot from SC to pump, pump to chiller, chiller to tank, tank to SC, repeat. My tank also is not just a tank, it’s baffled like a 4 pass shell and tube heat exchanger is. ie a 18” long 4”x4” tank is baffled into 4 1” square sections which are configured so from entry to exit is 4 1” square paths times 18” long each for an effective cold water column that is 64” long, add that to 36” of tube from chiller to tank and say 48” tank to SC inlet give a about 136” column of chilled water before the hot stuff starts to mix back into the mix. I get a 1/3rd to 1/2 mile run completed before I see a rise in chilled water temp at SC inlet.
I have been around large industrial chilled water systems for 25+ years, systems with 2400 tons of capacity with 200 hp circulation pumps. Hot water comes out of hot side of process return tank and goes to the chiller, returns from chiller and to the process. The mixing of hot water in the supply tank helps to prevent large temperature fluctuations to the inlet of the chillers which keeps expansion valves from hunting all over causing pressure fluctuations in the refrigerant system. The out let from the chillers feeding directly to the process then makes a huge column of stable temperature water which keeps process variations down. I modeled my system after this.
Here’s a portion of that chilled water system. @Hickster no playing with yourself with these pictures lol get a Playboy for that 😂

Mon!! You beez right upster in da mount tuns. Must beez quiet and blue ti ful dare. Wee beez in da fuut hills buttster you are in da moontains. luuks nice. Any parts stores dare??

Demid, guud fer youz. 5/8s ugh mile is fine. Buttster, watch out fer da utter fendars anz da wall abee. Dat place is more toree us fer da wall. Guud luck andz beez caeful. Ear plugs a mustardz.

 

[Demid22]

I wonder if something is up with the temp sensor. On the dash she gets to 50 degrees, chiller only. But theres literally a bit of ice forming on the coolant inlet on the blower. Ive swapped the sensor out, no chnage.

 

[Hickster]

Ifster ice formz eny warez. It's low on gas.

 

[Demid22]

So you're saying its still low on refrigerant?
