I used Bouchillon brackets and pieced the rest together myself of Ebag, etc. I came in at ~400 in parts with an offshore condenser, an off brand compressor of the model Bouchillon recommends for their bracket. I used mostly barrier hose, but bent up some AL tubing to get over the core support. I built my hoses myself and had a local A/C shop crimp them.

Hardest part was getting the charge right. I ended up at 2.2lbs. I spent a couple of hundred with the A/C shop getting the charge right.

Freeze you out is right, if ambient temps are in the 70s. On par with new cars at higher ambient temps, and blows away my wife's 2103 Huyndai and my 2001 Mustang. The referenced A/C shop said the great performance was likely due to keeping the factory (large by today's standards) engineered for R-12 evaporator.

R134, Sanden "shorty" style compressor (forget the model #)

Condenser was the largest that could fit in the 26" radiator opening. I found one with the in and out ports where I wanted them for hose routing convenience. I stuck with older tech expansion valve and o-ring fittings which kept the cost down dramatically.

And, this is in a 73 Barracuda, original A/C car. I can't speak to retro-ing to a non-a/c car.

It isn't that difficult to piece together sourcing most stuff on Ebay. That said, all the research and project planning was time consuming. The 800 Kit may be your best option if noodling it thorough is a time constraint.

I'm under the impression that the OEM Mopar air conditioning compressors are a lot better than the current after market Sanden units confused work
I would make sure first before switching twocents
I have a 1940 Ford Tudor sedan that I'm going to add air to and I want it as cool as possible, it is dark blue and relative big inside so the air will need to cool a lot of area. I've bought a trunk mounted unit from either Vintage Air or Southern Air but none of the under hood parts or lines yet. I'm thinking of adding a small under dash combination heater and air conditioning unit for heat and defroster also., lots of bridges to cross soon to get that car done luck

The Sanden compressors are considerably more efficient that the old Mopar compressor. The Sanden also fits better with certain other parts.

Like I said the Sanden with the original evap works great .

The sanden is lighter and is more efficient, sucking less power, providing 8-8.5 cfm
The factory one is good for 12cfm

As said, most of its in the condenser & heater box

A friend, before he died, said he used Thermo king stuff (semi trucks) much cheaper than the others. Never followed up with him on it, wish I had now.

You need a new a/c guy Doc. Old RV2 compressor setup charged with the right amount of r12 would freeze you out of the car. The key with the new r134 stuff is you need more cooling capacity in the condenser to make it really cold.

I think the reason a lot of AC systems underperform is the water valves or blend doors don't close completely and the system has to compete with the heater.

My KW has shut offs at the engine and I shut them off in the summer because with the heater set to cold you can still feel air warmer than ambient if you run the fan.

It's true. Those old V2 Chrysler compressors would FREEZE you out. When you start converting to newer refrigerants you really need to convert the entire system for it to work properly. My old '79 standard cab Adventurer would freeze inside the cab with the OEM system. I'd actually have to shut it off for a few minutes sometimes. Brrrrrr.


Facts are stubborn things.

Condenser, if front of radiator?

I think we may all have different definitions of "freeze you out". When I lived in FL, I had the RV2 setup with R12, it would sure freeze up the evaporator and fog the windows, and make me nauseous when jumping into it when it was all cooled down after being all hot and sweaty (I think because of the fast 30* or so temp change). Here in CO on hot, dry days, it never performed as well as hot Southern humid days. I haven't had the current setup in a humid/sea level climate yet, it (with a larger parallel flow condenser) performs much better than it ever did with the RV2.

And, given the low relative humidity out here, I rarely even get a drip from the evap. Shooting the Evap with my laser temp gun through the one vent where there is a site line to the core, I've seen it get as low as 27* when cruising on an 80*day on the interstate.

The Sanden takes noticeably less power and drags the idle hardly at all (relatively speaking). When I weighed all the pieces parts removed and those installed, the Sanden setup was 30 lbs lighter.

All that said, I always liked the look of the RV2 right in the V of the small block.
