Nearly finished with the second incarnation of my air conditioning air box. Stock location, stock vents, stock fan, and no body mods.

This is the continuation of the A/C compressor project thread.

Awesome! (IMG:style_emoticons/default/thumb3d.gif)

Is there any concern with the stock fan not pushing enough air for this to really be effective?

No idea. How would I know? (IMG:style_emoticons/default/wink.gif) We'll see soon enough, and don't forget while the car is in motion there is a high pressure zone pushing air into the air box.

This is how designing custom parts works. You gotta put down the pencil at some point and just build it, then see how it works.

Is there an option to recirculate the air through it? Otherwise your always competing with the outside air.
Awesome job though!! Are you going to sell any of this ala carte?

Also, could you make it big enough to stuff a heater core in?

I'll bet his design is for an Air Sucker so he'll probably keep the stock heat. (IMG:style_emoticons/default/beerchug.gif)

It's possible. But I have a different, and better idea for that.

Hey Mark,

I know you're working on a a/c compressor mount for the 6 version but did you happen to see the December Excellence? Check out page 81 there's a neat a/c install off the rear of the alt. Figured I pass this along in case it was missed and another way to get the compressor installed in a 914 w/o cutting into the firewall.
Keep up the great work.

Too bad there was no pictures or more information.

If you look carefully at the photo of the engine in the car on page 81, you can see the AC compressor over near the 1-3 bank of ITBs (blue and red line caps, belt tensioner, pulleys, etc.). He must have had the shaft of the alternator extended through the engine shroud and then mounted the compressor at the back of the engine over the 1,2,3 bank. Never seen that before!

Then you could run the lines to the condensor over in the right rear fenderwell (with a fan for cooling) or even under the engine lid like we've seen on the board here.

There's a better picture of the engine compartment on Excelence magazines web site.

There's a guy on the bird board from the UK that's working on a electric compressor system too. That may work (if you get a better alternator)

What a great idea.
It's the only place on a 911 block where there are mounting points that can handle such a load.
I'd like to see that alternator shaft. Or extension. Or however they did it.
It has a serpentine drive for the alternator/AC. Good thing.
Between the electric compressor idea and this there should be good AC for the 6 cylinder cars soon. Fingers crossed !

MFI is not gonna happen with this set up. No room for both pump and compressor in that area.
The compressor is not driven by the MFI cog belt from the 1-3 cam.
The accel. linkage must be interesting !
