Saab 9000 Boost loss

[MrMuffin667]

Where could I set base boost at?

[Twinsen]

Base boost is set by turning the threaded rod on the actuator so that its length changes.

[MrMuffin667]

Yeah, but where should I set it at?

[Twinsen]

You can lengthen it to the point where there's still some tension on the flap, or shorten it slightly. You don't want to raise the boost too much.

[MrMuffin667]

So would 7-9 be okay?

[Twinsen]

9 is probably too close to full boost. Can you go lower than 6?

[MrMuffin667]

Nope. 6 is as low as it gets. It's range is 6-25

[Twinsen]

You can try slowly increasing and see what happens.

[MrMuffin667]

As I shall. Should I be looking into a replacement APC? If that's the case, can I look for a good used one seeing as the new one if ungodly pricy

[MrMuffin667]

So I've decided I need to really start looking into turbo theory so i can learn all the technical stuff behind. I figure it will make building the car much easier. Does anybody know of a good Turbo Theory book out there? I know there are hundreds, Im just curious if some are better than others

What I do.
I use a pressure guage, with a hand put attached.
I pump up the wastegate until I notice the wastegate start to crack open.
Then I set the length of the rod to the upper range of the base boost figure.

I think, from what I read, if you go higher you will confuse the ECU and get fluctuating max boost performance.
