Cooling the LT1 with AC.

[Chris]

I am thinking its more of an issue with the pump staying on and putting a huge load on the motor because of the pressures you are creating in the Ac system.

That's what the guy who sells the kit was saying. Do you think a bigger radiator would keep the temps down, though?

I understand that this isn't the proper way to fix it, but I'm on a budget and paying someone to solve it would really be expensive.

No, produce some lines that have the correct sensors in them so you dont end up blowing a compressor to piece or a line

I've been doing some more research since I've never messed with A/C before. It looks like the pressure sensor just screws in onto the Schrader valve on the dryer and has two wires that I could tap into the wires that come off of the compressor. Am I missing something here?

bigger rad would be no help.

Mine had a 31" x19" radiator from the start, it developed a leak so I replaced it with a Griffin race one. A 31" x 19" 1 1/4" two row rated for 400- 600 hp. I used half of the Jaguar shroud and installed a single 17" fan from a late 80's Camaro. Temps run 160*- 180*. It was only $350 made to my specs. If you have room go bigger.

If you have room go bigger.

That's what a British car mechanic here told me. Apparently, even BMWs and Land Rovers here have problems with our heat. They're just not designed for it.

I went with this bad boy:

I did the math and it has just a fraction under twice as much cooling volume. I figure if it can cool a big block Chevy, it should do OK with my small block. Can't hurt anyway.

Something I just thought about today, but I wonder if my tune has something to do with my temps. It was tuned by Salomon to save on gas a little, which means it's a little lean.

I'll let you know what happens. Thanks to everyone who replied.

Does your air condition freeze you out of the car if you leave it on 24/7?

No. It always runs at 40 degrees Fahrenheit, but never freezes. I'm not sure what it's sensing, but the fact that it's so consistent tells me the PCM is involved. The only time it goes warmer is when the car starts to overheat.

The same mechanic I talked about earlier said his BMW will do this in traffic and he just ups the RPM to get the water to circulate more.
