Picture of Front A/C Condensor in SC?

[SeaDweller]

Can someone do me a HUGE favor and either post or send me some pictures of the front mounted condensor on the 911SC?

My ROW car has aftermarket, underdash A/C with condensors mounted on the engine lid and in the rear wheel well. I'm thinking of adding a front mounted condensor to duplicate the set-up outlined on the Griffith's site, but in looking at my car, I simply can't envision the installation.

Thanks a bunch!!

Michael,
Glad to see you got your paperwork. The front mounted condensor is of course mounted parallel to the road surface in the front center of the car. It has a stone guard and a fan mounted in the front of the trunk that draws air from behind the bumper and forces it down across this condensor. I will take some digital pictures this weekend and send them to you. I find it odd that my 83 Euro has this setup already. I am about to work on my AC to get it working and have the better compressor to install.

I greatly appreciate the pictures!

I wonder if all of the A/C systems in the late '70's Euro cars were under-dash? My system is quite well thought out. Originally, I thought it only had the lid mounted condensor, however I looked under the car one day, and found the second, rear wheel well mounted condensor.

The two issues I'd like to correct are:

1. While the A/C runs cold, it takes a long time to recover when the car is hot. Actually, it never does seem to recover.
2. The high fan speed is like medium on most A/C systems. The fan speed is controlled by a coil, so I wonder if I can change or modify to coil to increase the speed of the electric motor?

Griffith did that "Ice" project, and the addition they made to the car was the rear fender mounted condensor. I figure if I add the front condensor to my car, I'll have the same physical set-up. Then I'll simply have to figure out how to increase the fan speed for more air flow through the system.

The funny round cardboard piece is where I removed the air-horn out of my blower motor condensor... Apparently someone cut the blower motor horn and screwed this air-horn in it's place. I have removed the air-horn and placed this cardboard over it for now. No real difference in air flow.

Michael, I had the same problem with the ac system on my SC. I removed the bowtie on the vent under the dash & caped off the hoses going to the small vents on the side of dash the air comming out now will blow your hair back. Craig

oops ! Sorry I was not paying attention, you have an under the dash unit. Oh well it works great on the in dash units. Could your fan switch be faulity ? Craig

Craig,

It sounds like your A/C is factory in-dash. I have an under-dash system, and don't have the bowtie. There must be some way to increase the fan speed. Maybe a local electric motor company will know....

The fan switch works in all 3 positions, and I do get 3 speeds from the fan. It simply doesn't generate enough air on the high speed setting.

I understand the '86 and later blower motors are a bit faster (more volume?) blowing the air. Of course, they also got the bigger vents.

Just my luck

Michael, I also replaced the air hose running from the evaporator to the dash. I know that you have an under the dash unit,but i assume the principal is the same. is your evaporator in the well in the trunk? if it is check the supply to your under dass unit Craig

Did you check under the smugglers door, there is a blower there and a condensor (I think, not an AC man.) But it that is clogged up with dirt and muck then you will not get to much cooling as the air will not flow.

Actually, the blower motor and evaporator are integrated into the underdash unit. The smugglers box contains the receiver/dryer and the resistor coil for the fan speed settings. I'm going to check with a local electric motor shop to see if there's anything I can do about the fan speed. I also think by adding the front condensor, I could lower the vent temps, which will help quite a bit.

Sheesh, I'll have so many fans on this car when I'm done, that I won't need the engine for propulsion!

Craig-
Where did you get the replacement hose (evaporator box to dash duct)? Did you order the part from Porsche or did you adapt some other kind of readily available hose? Mine is totally rotten and frayed.

Thanks.

Hello

Seems like your underdash unit is aftermarked.

The resistors ( coils ) are for the lower fan speeds.

Upgrading to newer 86 fan is possible but the housing changed to even the door. http://www.pelicanparts.com/911/911_Parts/1974-75/0-6.JPG shows the old setup with the engine siting low. the newerunits have the fan engine sit upside down and a bit larger evaporator.
