The car squats and pulls the front up hard now. It drives like the torsion bars are too soft again.

I need dyno time. Itís impossible to watch everything.
The factory boost gauge is notoriously unreliable. Mine works, but is definitely not accurate and shows higher like yours seems to. I trust my PLX gauge, not the stock one.

I was able to get the AC recharged today. I had an issue with higher than expected high side pressures.
Rawknee bailed me out again and explained it was due to the condenser fan being disconnected. Two of the retaining straps broke, so I disabled the fan. Without that fan the pressures skyrocketed quickly.
I fixed the fan and the system charged normally. I had 30* vent temperatures last time, but the system froze on me a couple times.
This time I stopped at 33* vent temps with 225/20 pressures. There is a low pressure system moving in so it was only 78* ambient.

After that I put my first timing program in. 10* at idle to 32* at 2k with 5* retard to 27* at 14.5 psi. Very basic slope with no curve. Idle is better and low end from a stop is better. No detonation on boost.

My only problem is the enrichment disc for the wur is pushed all the way in and Iím still at 10.8 afr onset to 11.5 afr @ 13.5psi.
How do I lean this out? Do I have a bad WUR?

Glad to help with the a/c situation, Deez ***forum dating***, I know!

About the AFR numbers - try leaning out the warm control pressure a few tenths - your car will likely cruise just fine (mine does even at 14.8-15.0, as mentioned previously) and you will see an accompanying leaning out of boost/enrichment AFRs, to some degree.

I'm not sure about the boost onset numbers - have you tried tuning around that with the boost onset fine tune on the WUR?

I figured. It quits working once in a while too. Maybe twice a year.
I thinks it's more of a novelty gauge to sell cars.

79 #610 Winter Projects. Advise Needed

So third time is a charm for adjusting the AAR. I learned the small pin can be pushed in to close the opening and reduce idle RPM. It also fully closes sooner. I think the new turbo and long neck increased air flow at idle causing the bypass to need adjusting. My cold rpm was 2,800!!!




Iím not 100% done, but done enough to drive it to Napa tomorrow! I finished barely in time for our 17th Anniversary trip.

Washed and ready to go.

This is so cool, I didn't know the AAR was adjustable, I'm gonna play with that.

^^^ Go a little at a time. You can't open it without full disassembly. See the bolts where the rivets should be. It's a total PIA to get the cap off the other side to access the nut.


So there is no such thing as being done with an old car.

The drivers window motor or regulator is jumping teeth now. Window gets half way up then pop,pop,pop. I tried lubing the felt with some silicone to see if the glass was binding and it still does it. I need to fix that now.

And the AC has an issue. While driving with the AC on for 10/15 min the whole system started turning off and on. Blower motor, fans, compressor; everything.
So I need to check pressures and try and duplicate the symptom. I have one of several things I think can cause this.
1. Pressures too high and tripping the switch
2. Faulty pressure switch
3. Faulty relay <--- wouldn't that be a nice and easy fix...
4. Faulty or clogged expansion valve

Any thing else that could cause this?

^^^

Deez, the pressure switch/too high or low pressures only affects the compressor clutch operation (evapor fan, etc, still functions) - same with the expansion valve being plugged (no effect on evap fan operation). The whole system shutting down is likely the "whole system" relay in the smuggler's box or some other wiring issue.

Yo' Deez, per our non-forum troubleshooting conversation about the unique placement and function of your pressure switch (unique with regard to other 911 systems), make sure that the switch and/or dryer body is adequately grounded - for testing purposes, maybe temporarily ground with alligator clips and wires and see how it responds.

^^^ I'll check that too. It will be later in the week or next week.
I decided yesterday to take a short break after 5 months of non stop Porsche wrenching.
I need to get a few house and yard projects done.

^^^ Yep, house work. I had a storage container dropped off Monday. Moving everything out of the garage. My Man cave needs a remodel.
I'm going to fix the walls and paint, level the floor and epoxy, get some nice cabinets and a tool box.

Thanks for the complements. I'd like to get on the Dyno but Don's has been down for a few weeks. They are supposed to get it fixed this week. There is a lot of people waiting in front of me.
I'd go somewhere else, but I've known Don for 20-25 years. I'll wait.

79 #610 Winter Projects. Advise Needed

It took longer than I expected, but I finally have an organized and clean garage.
Fixed the walls and painted, leveled the floor and epoxy coated, and got some good cabinets and tool boxes.
No more Home Depot shelving for work benches.

Now back to working on the 930.




The only before shot I have. I’m so bad at remembering to take before pics.

Derrick,

A before and after shot would be great! I know you did a lot of work there.

That must be VERY satisfying. The "wet look" floor looks great. John.
