I used the Vintage Air AC/Alternator front mount. The Compressor is a Sanden and the Powermaster Alternator is a 100 Amp. The AC unit is an Old Air Products Hurricane electronic unit.
With every electric device turned on I have: headlights on high beam, radio, AC, (fan on high) electric wipers, backup lights, my load is 34 Amps. I do not have a massive radio with power amps or bass banging ear splitting speakers. The AC will freeze you out on medium fan.
I have 3 pulleys. The alternator is the only one going around the water pump and crank.The PS and AC compressor each have their own belt off the crank. In 4 years there in no slippage or noise from any belt
When the AC is turned on the RPM drops 25. These compressor don’t have the loaded draw as the ones of the past… Good luck.
That's what I was looking to start with. The Vintage Air Brackets. But we are adding EFI, electric fans, electric fuel pump, dual A/C, power inverter etc etc. The electric fans are always a big draw thus the bigger alternator. I've installed a bunch of power master stuff and had issues with their bigger units chipping a single V belt when they switch on at start up, all the manufactures I looked up also said single V belt wasn't recommended over 90amps load. I don't think we will be there continuously, but certainly will see peaks in that range. You know how a belt gets once it slips!
I thought about the double V belt going around Crank, Wp, alt and compressor, but you lose a ton of belt wrap on everything and I don't think that would gain much. With the serpentine set up a couple idlers quickly fixes any wrap issues.
I looked at the commercially available kit on the market and it won't work for us as the alternator sits where the Turbo is going to live. The Vintage Air bracket would be perfect.
