Jim,
Thanks for the info.
I just got the A/C up and running on my SC with a pretty much stock system and it's doing very good. I got 32 deg. temp's at the vents but it didn't want to maintain it on a 90+ degree day and went up into the low 40's.
I think your hitting the nail on the head with the added fan's though. The fan in my smugglers box was tired and starting to make noise and once replaced with a new unit it made a big improvement by just blowing more air.
I added the khuel vent to make better use of the bow tie vent air flow and that was a big help. It's pricey but a good fit that installs easy and looks factory. And to me for the 150/ shipped a cheap improvement to get better working a/c.
They put freeze 12 in my system as it's hoses are original. The York compressor was replaced with a Sanden, another big improvement.
I am curious about a fan on the rear condensor as I've heard that mentioned before.
Keep cool
