I bought small fans and relays to install on the rear condenser, but I need to wait until I remove the AC manifold gauges, before I install them.
Waiting for the new CHT sensor to come in, so I can finish up installing those and the flywheel sensors.

The electric fans on the rear condenser really do almost nothing unless you are sitting at a traffic stop for a long time. The big engine fan pulls a ton more air even at idle.
The real trick is the Griffith's two rear fender condensers. And a really really really good vacuum. They system has to be moisture free, and moisture will turn to ice and hide in the long hoses and multiple components.
It is truly impossible to achieve too good of a vacuum.
Of course it all comes down to what you expect from your AC. If you live in So Cal, or up north where 100+ days are rare, it the system is not tasked much. If you live in an area with 100+ days on a regular basis, you will want Griffith's full Mr. Ice project. That is what I have, and I just love the cold air when it is 100+ outside, and my wife is happy to ride with me.
