I want a high amp alternator that I can run with my new style AC. I just feel like there has to be a solution out there and I missed it. I've dug through alot of posts but can't find a definitive answer. Here is what I have run into. AREngineering makes the Denso bracket, but it won't work with AC from what I have read. Bouchillon Perf. makes a relocation bracket for the AC unit that allows you to move the compressor below the altenator, but they say it won't work with the AR Eng. bracket. What other solutions are there? I'm not married to the Denso alternator, but I really like the way it looks compared to the GM units. Also, I have already upgraded all of my wiring harness and ditched the dash amp meter. 69 Super Bee 440 5-speed 70 Dart Swinger 340 4-speed 69 Camaro SS 396 4-speed 66 Cutlass Convertilbe 70 Judge Ram Air III 4-speed 68 F-100 SWB

I ended up using an AC-Delco CS 144 for that very reason. It effortlessly runs all my add-on electrical accessories with the engine idling at 800rpm; Halogen headlights, twin Spal high-output fans, large electric fuel pump, MSD, and A/C. Most people(Moparts members excepted) never even notice it's not a Mopar alternator either, but then again, most people don't notice my car has A/C. 7284830-IMG_2551(Large).JPG (133 downloads) 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

The CS 144 has remote voltage sensing if you want to use it. I found it uneccessary as it puts out more than enough amps to keep the voltage up at the rear mounted battery. 7284841-IMG_2550(Large).JPG (123 downloads) Last edited by jbc426; 07/09/12 07:52 PM. 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

What brackets are you using for the alternator and compressor?

When the squareback wouldn't cut it for me I took the setup from my core engine... the big 100+A Chrysler unit per the pic. It works great... just heavy. The swing arc for the Chrysler alternator and matching brackets is bigger than the Denso. As a winter project I'll try to fab an adator fitting to mount the Denso in the Chrysler bracket. PS: I had to lengthen the water neck by about 2" so the stock type top hose would clear the belts with room to spare.

Thanks, Tim Thanks. I used a $35 adaptor braket that I got on-line and then all the factory Mopar alternator stuff. For the A/C, I used Buchillon's under alternator kit, but then modified it so I have about 30% more belt wrap on both the crank-to-A/C compressor and A/C compressor-to-alternator pulleys. Both the A/C and alternator have their own belt with the A/C driving the alternator on it's second pulley groove. I found the way Buchillon's belt path was designed to be run resulted in belt squeel and inadequate power transfer to the A/C and alternator in my case, as only about 30% of the A/C & alternator pulleys made contact with the belt. By changing the belt routing, I was able to get over 50% belt wrap on both pulleys. The Buchillon kit also requires you to use an electric fuel pump, which I wanted to run anyway. My water pump and Power steering use a separate belt. 7286629-DSCF0272(Large).JPG (86 downloads) 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

Does the CS144 take a special plug at the alternator?

Does the CS144 take a special plug at the alternator? Thanks! I basically followed the Madelectric layout. I have a 2 gauge cable with a 200 amp fuse going from the alternator output lug to a power distribution lug under the hood. The CS 144 plug-in tail is readily available on-line and in auto parts stores. The wiring diagram is for it is simple. I'm only using 2 of the 4 plug-in wires plus the cable. I did have a heavy duty bridge rectifier installed in it and had the stator rewound on the CS-144, so it puts out a bit more than a stock one. All my heavy amp draw stuff is either fused or fusible link protected and running through key-switched relays. I have no high amp draw inside the cabin of the car. It's all distributed up front except the fuel pump which is in the trunk & hooked-up near the battery. Only low amp voltage goes through my bulkhead for lights and such, even the headlights are feed all but control voltage from under the hood. I have a "0" gauge cable running from the distribution lug to the trunk mounted main shutoff and battery. The cable is carefully routed, shielded and fused so it's protected against shorts 100% of the time. Finally, all this aftermarket stuff is mounted using the factory holes and such, so it can easily be removed and the car returned to it's stock configuration. 7287118-IMG_1351(Large).JPG (93 downloads) Last edited by jbc426; 07/11/12 05:50 PM. 1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)
