opinions on A/C parts and needs etc..

Hi I am finally going to do the ac in my car after threatening to do so for many years.
I have a nipendenso compressor, all new lines bought 10 years ago.. I have stock front condenser, belly condenser, and classic retrofit blower/evap unit. I also have switches somewhere and a firm desire. Question is if I also get the csf rear condenser for non turbo cars will I need any additional condenser than it? Like I say I have the stock front and that belly condenser if I need it. But I have no idea the capacity needed after that rear parallel flow unit if any. Is it a matter of more is better? Is that belly unit still good? is the front stock unit any good?
I am open to any and everything. I'll even but a whole new kit........
Thanks.


My car is turbo and I have eliminated the air intercooler.

Well he hasn’t responded to my online query.

Have you considered the Classic Retrofit all-electric AC system?

[gsxrken]

Condensers are good, which is why Griff offers the dual rear fender kit for certain applications. My 930 (with the small 1/2 bay condenser because of the intercooler) has them, for a total of 4. You should be able to duplicate the normally aspirated cars with the large rear condenser, loop through the front one (make sure your front fan is working and fused), and be good to go. Considering you have all the parts, I’d call not email Griff and purchase the rear condenser and to get his advise on further mods. Plenty of guys are happy with a well sorted stock system which is what you’d have.

PS- you will use the car a lot more with AC.

I did. I do have some of that kit. I have the evap blower unit. It’s nice, it blows pretty strong and I like that it’ll work without the evap part in the smugglers box.
I didn’t want to add the larger capacity alternator because mine is so fresh and it’s more expensive. Also all the parts I already have.

Thanks. Sounds like more than the rear full grill condenser is a good idea.
Has anyone tried that condenser that pelican sells? It’s made by csf and is the parallel flow. Looks like a great fit.
I may need a fender condenser as well.

I have a stock front condenser and a front fender condenser and that is enough. I haven't had to operate the system at its max yet. This is on a 1985 backdated Targa with black interior based in southern California.

[quattrorunner]

Nice. I am in a climate similar but slightly cooler(5* cooler) to Las Vegas.
This car has never ever had a/c.

[chucksmith]

I have the griffiths front belly condenser and left rear fender one(with fan) as well as new griffiths evaporator and blower, new lines and modern compressor. It works great here in the south.

We just installed the Griffith full four condenser system on an 88 M491 and achieved 25*F at idle on a warm day.

Another 88 M491 only did the front condenser upgrade and only achieved 40*F while driving and climbed to 57* at idle.

If you want to go with a stock style system with an engine driven compressor then you need to make sure you get a more modern micro tube condenser. Several manufacturers make those, but with our 134 refrigerant especially, they’re massively increased efficiency over the factory style condensers makes a huge difference.

The biggest issue with factory style air conditioning is that the fan inside the smugglers box on top of the evaporator simply cannot move enough air. There was no option until Classic Retrofit brought out their blower. You can hook up their blower to your engine, driven air, compressor, and factory condenser, and I think they even have a kit to do that if you want. Is that alone will make a massive improvement in the air conditioning. And if you want to clean up your engine bay, and pick up horsepower when the air conditioning is running, you can always go to their full electric kit

I did buy their blower evap unit and it is nice. I intend to use that with a standard compressor.

The lack of condenser capacity is the big issue with the SC and Carrera models. Griffith's offers the Mr. Ice project. It simply works. I have had mine since 1996 and over 75,000 miles. It just makes cold air in the hottest conditions. Contact Charlie Griffiths and tell him about your car, and your goals.

My goal was to have my wife go with me to the hottest parts of the country and be happy. Happy wife, happy life. And I love my wife and my ice cold air conditioning.

IMHO opinion if you get the CSF rear deck lid condenser that should be fine. I have 2 Boxster condensers (small and square), So I am pretty sure you will have more condenser area than I do. I could run it without fans and see how it is. Fans will only help below say 20 mph, and even then they may not. The engine fan moves A-LOT of air. So as long as the condenser is seals to the deck lid well, and the engine tins area sealed well to the body, you should be fine no fans on the condenser. Utah is very dry, esp comparedto my Florida. My 3.2 Carrera does not have a fan on its deck lid condenser on a system similar to a full Griffiths, and it works great. Good luck.


Edited so it makes more sense.

I too only had a rear lid condenser on my “74 Targa. Would freeze my nuts off. Now that I went with a modern electronic induction system, the lid condenser won’t clear the air cleaners. Going to try a rear fender unit, with a fan, to see how that works.

You can glance thru this old thread from when I installed air in my car. Still cools great after many years.
