Ryan: Here's what I did, and I'm getting mid-to-high 30s out of my vents on a 85-90 degree California day.

1. Replaced all my hoses with Griffiths barrier hoses. (If I had it to do all over again, I'd use Rennaire.)

2. Installed a rebuilt Nippondenso compressor (same as stock). Reused my clutch.

3. Replaced the receiver/drier with a ProCooler.

4. Cleaned and re-sealed the evaporator box using a kit from Griffiths. Money very well spent. While the box was open, I cleaned the evaporator's tubes and fins.

5. Installed a condenser/fan assembly in the front left fender, and relocated an aftermarket washer bottle to the trunk.

6. Had the system professionally evacuated and recharged with R12.

Was it the ProCooler that made the difference? The auxiliary condenser/fan assembly? Both? Neither? I have no way of knowing. The bottom line is that it all works.

I hope this helps. Have a double scoop, it's on me!!

Mike, here's one for you too, buddy!

I don't usually get involved, but let me say da911enginear that Scottb is a very helpful member of this board I don't take kindly to your random punches. We're all Porsche guys here, be nice........you just got here!(7 posts)

Agreed. Appolgeeze to Scottb. Comment was not ment to be a punch, simply a jest.

Let's move on.

Anyway, you got real good results with home brewed. And I find it interesting.

What I'd like to know has anyone explored sealing off the deck lid condenser to get more cfm across it ? Here is were home brewing could pay off.

Is there a better ac thermostat device for the cockpit and evap out there?

[da911enginear]

to scottb, you pm box is full, could not send to you,

the answer is "yes, seal off (mask) deck cond.

would sealing off around the rear deck condenser restrict engine cooling, even by blocking that little amount? i have no aux oil cooler, so i have to be mindful of anything that might impede cooling.

Even though the entire bottom of the engine is open, I fear that doing anything that decreases the flow of air to the engine compartment will result in increased engine temps. They don't call 'em "air cooled" for nuthin', ya know?

[da911enginear]

not sealing off the entire air inlet through the deck lid, but rather sealing around deck lid condenser so air moves through the condenser rather than around it.

You could use some of that expanding foam in a can to seal off the condensor - I think it's called Great Stuff"!

right..i understood that..i just meant that what sir doesn't go directly through the condenser is still pretty important for engine cooling flow. blocking off around the condenser doesn't seem like it would 'help the condenser flow' to me.

i'm "assuming" since Porsche surrounded the engine with a seal, they had two things in mind, dirt and weather. If they thought they needed more air "cool" for intake and air cooling they would "bypass' the condenser with another path (excluding the design of the decklid to rear body or fender panels). And we'll assume that at sometime when the consumer pushed sales to get air in the car there may have been some reluctance between engine engineering and comfort engineering. Since there was no frontal area for a condenser they adapted the deck lid approach. Assume as well that someone in the engine group did testing on the engine temp rises with the deck lid condenser and they "blessed" the beast unwillingly.

I guess the true test will be to do something like holding some smoke around the seam or joiner where the deck lid meets the rear panels and rev the engine and watch for the pull. Then maybe mask off those same entrances as well as the large open areas where the deck lid condenser mates up. In between do a before and after of engine oil temps with an accurate probe.

Just a thought.........

However don't use the GREAT STUFF....... Why?
Because we all know better.
