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 …

Just bought a motor.

Post  Arthropraxis on Mon Dec 14, 2009 7:43 pm

I just bought a 2004 LS1 out of a GTO. I saw on the PHB that people had issues running AC with this ECU. Are there any other problems I may run into that are different from the F body motors? I know there are several members that migrated here that have this motor,so share your experience with me. Thanks

I don't have experience with the GTO motor, but if you hook up your ac using all the Porsche system (except for the compressor) all you should have to do is feed the ECU an ac input to let it know that it is on. This will help control the idle. In reality though the LS motors don't even budge on the idle hardly at all when the ac compressor comes on. If you use all the Porsche system you don't need all the LS ECU BS!

What do you mean?

Post  Arthropraxis on Mon Dec 14, 2009 9:34 pm

I still have most of the AC hooked up. I took some wiring off the 14 pin harness, per the manual, but that could go back on. Can I use the Porsche AC? I am not going to run power steering could I relocate the alternator higher and keep the AC compressor where it is?

You could use the Porsche compressor. You would have to fab some brackets. The motor will not know the difference. The 14 pin connector does not have any relevant wires in it, as far as the AC goes....

While we're on the subject...who is actually running A/C? My understanding was that it was too much for the small 944 radiator to handle. I could see it working at highway speeds though.

I am going to get another radiator

Post  Arthropraxis on Tue Dec 15, 2009 11:42 am

The griffin radiator posted on another tread should work. I am going to try to get a condenser that doesn't block so much of the radiator. I would like to keep the porsche unit but there will be no fabbing going on over here. I wouln't know where to begin. I found a place called coldhose.com that will make custom ac lines. So soon I will need some info on what to order.

I didn't really see any specs on the radiator in that thread, but i know that most of the aftermarket radiators, size for size, can't compete with the 951 radiator. On the last board we had some discussion about how the RH radiator, even though it's ~1" larger, doesn't have the cooling capacity of the 951 radiator.

That being said, some people didn't think the 951 radiator had the cooling capacity for A/C.

Not being argumentative here, i'm just really curious. Most of what i read on the old board indicated that the 951 just couldn't handle A/C, so it's been something i've just assumed i had to live without.

Then again, my car idles at around 190*, so i think it could probably handle another 20* or so....

I read all that I could search about AC on the PHB

Post  Arthropraxis on Tue Dec 15, 2009 2:49 pm

Lots of conflicting information on the PHB. Some say the turbo radiator and fans are enough and others say it won't work. It is over 20 years old with plastic endtanks. I would think a new one would be more efficient. The chapter in the manual makes a solid case for a bigger radiator and fans.

I have the Taurus fan on mine, but i'm not sure how much more it actually does...

I had my 951 radiator flushed, and the plastic end tanks are cheap but don't necessarily affect cooling. The biggest concern of mine was cooling capacity, the 951 radiator had a few more square inches than the RH radiator at least. The one in the other thread is double-pass, which should help with efficiency, but still...

I dunno, i certainly won't discourage you from trying it out! I'd love to get the AC working on mine sometime. I remember there was someone on PHB that had working AC in Texas and they said it wasn't a problem. Worst case you could turn it off at stoplights! It might also help to get the "bolt in crossmember" here: [You must be registered and logged in to see this link.] looks like it ought to increase airflow quite a bit.

I was thinking about getting that too.

Post  Arthropraxis on Wed Dec 16, 2009 11:57 am

I just want to get the conversion parts first and get it running. I am just trying not to have to do things twice. But then the frugal side of me comes out and I think well I already have this why not see if it doesn't work before buying anything new.

Sounds good, keep us updated!
BTW, you might check around your area for the hoses. Any place that can make hydraulic hoses ought to be able to make you some A/C hoses. It's always nicer to deal face to face when you're making 1-off parts!
