I have been looking into accessory drives again and for some reason I'd rather have the ac mounted low to keep everything tucked in and not break the bank. I found a new Holley bracket for the Gen V LT1/4 setups but nobody makes the truck version nor do I want to make a bracket at this time. I think I'm also going to add the ICT power steering pump bracket that sits under the alternator.
I did some research and a good amount of people run the Gen V compressors on their swaps and they do so with Vintage Air too. A guy from Pro-Touring shed some light on how to make the variable displacement compressor on the Gen V compressors run in the fixed displacement mode. Its very simple if I understand correctly... just supply 12v to the variable displacement valve (2nd plug on compressor) when the compressor clutch is activated and it will operate like a fixed compressor. From my understanding of the LS3 style compressors is that they are variable and they do not have an extra plug like the gen V compressors to send the 12v to.
I spoke to Speartech about this and they are not too familiar with the AC compressors but they did tell me that when they were first doing the Gen V harnesses a customer requested his harness to be setup for the factory compressor and they did so. The customer reached out to them with a problem, his compressor was not accepting a charge. They determined the problem with this is that the valve needed to see 12v in order for the compressor to work correctly. I'm assuming the factory AC system sends some sort of signal on and off to make it variable or something along those lines? So we will see if a constant 12v when the clutch is activated will get the job done? Speartech said they now setup their harnesses using the factory compressor so that the valve sees 12v when the clutch is activated. They also recommend a Sanden compressor rather than the factory if possible so we'll see. If all else fails I can find a way to stick a Sanden unit in there later down the road.
Now I have cut the ICT motor mount adapters to fit the compressor. The compressor sits snug against the block.
