I'm guessing you have the a/c evaporator somehow attached to the stock blower and are just using the stocker blower to circulate? Or is there an entirely different blower? Are the motor and compressor one small unit similar to that of a window mounted a/c unit? The technology for those things is so cheap and compact I figured it was only a matter of time until it bleed into the auto industry, especially for mid and rear engine cars where running an engine-mounted compressor is an exercise in cutting and fitting seemingly dubious hoses.

Re the amp draw: that's not a bad amp draw and if a person were truly concerned they could create a separate fused system adjacent the stock fuse box (or wherever) and run a higher amperage alternator which is extremely easy. I regularly run uprated alternators on 70-80s vintage Ferrari's with zero issues.

Kind of interested to know where this dumps the heat condensor wise ?? Still need some hoses there. Otherwise, a good idea.

Oh Johny. I am so in on this. I am in Dallas, this would really work out well for me. I hope you can get it ready to go by the time I need that new fuse block this winter

Interesting to hear how this works. Would rush to market if it's functioning as posted in the video.

GREAT IDEA!!! You should redo that video with some editing and a good camera and mike. You are a professional company and it is tough to hear people say they could not hear audio or switch it off.

Electric compressor is great tech and a great application in early 911s that don't need more stuff in the engine compartment, and benefit from weight way way up front. Not to mention shorter hoses that are all in the same are. BRILLIANT!!!

Look forward to hearing more.......








I have been working on my own electric a/c systems, but the prototypes are pretty rough, but I will give you a sneak preview:







LINCOLN PROTOTYPE UNDER TEST




CHRYSLER PROTOTYPE






PICK UP LONG TERM TESTING

I'd would be very happy and very surprised if a stock alternator could keep up with a massive draw like this.

I've always wished for some kind of fan bracket and AC-to-alternator bracket so that I could replace the bespoke 911 alternator with a $100 bog-standard high-output alternator that you can find on any modern car. Replacement costs for 911 alternators, particularly if done professionally, are costly, and none of them work particularly well.

Should be interesting to watch development.

Wonder if it'll work in a 914 with a 911 engine/alternator.
Hmmm...maybe in a 356 if I change it all over to 12v....hmmmmm

Good point above where are the dumping the heat out?

I was thinking similar tech to a window unit - all contained in one package that could be removed.

Got a good laugh out of the lengths people have gone to to add window units to their cars :-)

Much speculation and assumptions beign made here. Pelican ac threads are always such fun!

Yes, we use an electric compressor but it is not the 'Jegs' one. The condensor is under the front fender in place of the huge washer bottle (30lbs when full of water!). The COP for the compressor means we get twice the cooling output power for the input power.

40A is not a massive amount of current. You are using more than that everytime you drive with lights and defogger. It is vital to manage the power though.

The heart of our system is our own custom power management controller. This can be configured to match the power budget of the car. The controller regulates the compressor speed in order to maintain a healthy charging system and battery.

The early cars will need an uprated alternator so we will provide one with the kit.

We are engineers who like to share. I'm sorry about the audio and my accent but the real thing to observe here is the temperatures. There are no tricks. I drove the car 200 miles one day last week with the a/c on all the time. Battery and charging system AOK.

To you guys in Texas, we make no promises until we have done some proper hot weather testing!

Sorry if I missed an earlier post but do you have a ballpark on the cost of the kit? I know it might be too early to give a rough estimate so forgive me if I'm jumping the gun. I am very interested in this.

It is likely to cost a bit more than the conventional kits because the parts are less common and we have R&D cost to recoup. You will save on installation costs and of course, weight!

Btw, no holes drilled in the shell.

My 72 will be going into assembly next year. I have planned for AC. This looks like a worthy installation. So much better than the original system parts. Now, What about some vents in an early car?

I'll say it a gain, I am your perfect beta tester. I already pulled that monstrous washer bottle from my build and as previously posted, I am NOT putting in any rear-mounted, hose-crazy engine-driven AC systems in my build. See build thread below.

My WAY over budget /backdate/lightweight/hot rod..

I was planning on driving hot until someone solved it with an electrical system. PM me if you want to talk about it more.

The Coefficient Of Performance is more than the compressor isn't it? Includes condenser, evaporator etc.

Does this mean this kit would not work for those with oil coolers in both fenders? That's how mine is set up. Are there any other alternatives for condenser placement?

Electric powered automotive a/c sounds interesting!
