HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Does anyone know of a adaptor/fitting that connects with the 944 bulkhead larger (suction) fitting?
The fitting on the right side of the picture. Sorry it's out of focus.
Other than cutting the end off the existing line and welding on a crimp type hose fitting are there any other options?
Compressor now on the passenger side and requires a new suction hose.
Thanks.[You must be registered and logged in to see this image.]

I never could find one, so I welded a fitting on. Let us know if you come across one.

My solution was to take the original Porsche fitting and braze in an adapter block and port to mate with the Chevy AC Pressure sensor. The adapter and port came from Docsblocks.com. I then took the Chevy AC manifold (compressor side) and had the hoses cut off so that 37 degree (male) flare fittings could be brazed on. I then spec'd and ordered custom AC hoses from coldhose.com to join the two together. I did this for both high side and low side lines.

I required the Chevy port because I wanted the Chevy PCM to control the AC compressor. If you want to leave the compressor control to the Porsche side of the car, then just leave out the adapter block and use the same methodology with custom made hoses and 37 degree flares.

Bridar, Thanks for your picture, I'm curious what setup you are using.

I have a F body Compressor mounted on the Passenger side.
I will run the original thinner line from thr firewall to the dryer/switch, then
from the dryer/switch to the condensor all using existing lines.
A new line from the condensor across the radiator to the compressor and then from the compressor suction outlet to the firewall larger diameter connection.

Is this the same as yours Bridar?

Also note I have disabled the valve in the Compressor to make it a constant pressure system.

Your are correct. My system is just like what you are planning. I have the 2002 Camaro compressor as well. I posted some pics in my gallery that will let you see how I routed things. Note that I opted to use a J-style fitting on the larger pipe so that I could both route it away from the tight area where the main wire harness enters the firewall and so that the hose could be re-routed to the passenger side (compressor side) of the car. It looks a little odd but works for me.

I am curious why you changed over to a constant pressure system? What are the benefits of doing this and how is it done? What are you doing for clutch control? (Porsche climate control module or Chevy PCM?)

Here are the AC fittings I had made.

The bulkhead fitting was cut from the existing line and welded to an aluminium weld fitting.

The Condensor fitting again was cut from the existing line and now loops back across the radiator
to the compressor on the passenger side.

Nice Mike! Have you connected the hoses to the compressor yet? Love to see pics of it and your hose routing if you have!

Not hooked up yet, wrong fitting showed up today. I plan to use 180 degree bends so the hoses leave the compressor near vertical. One will loop below the condensor to reach the 180 fitting shown above.
The other will loop along the passenger strut tower to the the bulkhead fitting shown above.
Picture below is my compressor with a manifold that exit downwards.

I like it. I think I might have some clearance issues if I were to go vertically from the compressor like you are doing, my headers are pretty close there. Maybe not though...

If it helps, in case you didn't see it, there is an adaptor block just like the one you have installed on your compressor, except it has the outlets pointing up instead of down.

I'm having problems with a leak at the bulkhead fitting from the compressor. It has been welded twice.
I think the Porsche alloy cracks when heated.
I wish I could find a better bulkhead fitting.

Fliermike, i might have missed it, but where did you get the block that faces downward?
