I am planning on removing this shortly as I have Brian Leask's asjustable wur and will be doing the boost solenoid as well.

However, I was curious if anyone knows anything about my setup / how it works (came on the car). This was done probably back between 91 and 95.

There is a small **** in the console with about 6-8 adjustment points. There is a small box under the seat but I do not recall if there were any markings. Out back, you can see in the picture.

Also that white wire goes to the boost pressure switch on the back of the intercooler.

Cheers.

White wire attaches to red cirlcled post.

I'm pretty sure you have the Andial package. Here are the components (sans the black ****):



You can probably get $300 or so for a used unit

Looks pretty close. Any ideas on how it operates, what the **** positions do? I don't have any manual for it.

I'll do some searching in the mean time.

Thanks!

Here's Andial's explanation:

Thanks!

I have the same Andial kit. It has 6 positions, the most counter-clock wise setting will increase the fuel delivery the most from what the PO told me but not necessary more power. I haven't had time to play with it but I think I found someone with the manual. The red light on the top lights up wihen the boost is on....very useful.

Cool. I'd like to get a copy of that manual if you find it, whether paper or digital.

Let me know.

I am debating the removal of it. I don't think I will need it with Brian Leask wur, rpm solenoid, and 1 bar. However, if I wanted to go past 1 bar...my thought is that changing the boost switch to something higher, say .9 or 1 bar for the additional Andial fuel enrichment to kick in. Of course an afr, dyno, etc would need to be run to see if/when we start running lean. And then of course there is the IA fuel head mod....what do do!

I have a copy of the manual if anyone ever needs it. For the most part junk by the way (except for the wiring).

The question I now have, is do I no longer have overboost protection? It seems that the pressure switch used to trigger the enrichment replaced the overboost switch.

What happened to the wire that ran to the original overboost switch?

Ag02M5

I have no idea.

What does it look like, where does it go?

Trying to get the car all sorted out after all these years.

Can't tell by the picture, but most probably a grounding wire for the over boost switch?

On the 930 they are white. Don't know much about the 964t, sorry.

Look @ 10mm head bolt on driver side of intercooler where blow off valve hooks to intercooler and if it has two wires connected to it 1 of them is probably the wire for overboost switch that someone has grounded. The other one is brown .That is the easiest way to do so and on c2 turbo it is a small white wire, looks kind of tan on mine with age.

And to the other question ,"just read your question again ,"you do not have factory over boost any more .
