I can get some easy, no prob. I originally insulated both lines, thinking that I'd be keeping the heat from the high line out of the engine bay. And while this is true, it's not as good for the AC. Remember, that keeps the hot side even hotter and sends that right back into circulation.
Kinda defeats the purpose of getting it COLDer...lol
So I took the insul off the high side and let it radiate into the engine bay. It's minimal anyways as it runs right past the well vent. My AC is a LOT colder.
I've never got it under 40 though. Before the insul I was getting around 52-54 degrees on max. After the insul and a r-134a charge I can get it as low as 43 degrees. This is on fan 2 with the recirculation button pressed.
Keep in mind, I have the UD pulley, so that's limiting my cooling potential. But I'll be honest, at 43 degrees, I'm very very chilly....heh. On the trip home from NY yesterday (525 miles) I had to leave it on fan 1 with the thermostat towards the middle, or else we were cold.
That's plenty for me
I'll get pictures in a little bit.
