I hear this part being mentioned a lot of times.
What is it? What does it do? Where is it?

Any pictures of it?

Thanks

 

Nobody knows anything about the restrictor?

 

Which one, which model, what problems are you having, do a search.

If it is the one I think you are talking about it is off the compressor outlet and shifts the control bandwidth of the 2 port solenoid so that the ECU can control boost between 8 and about 20 PSI depending on car. You can alter rate of boost rise by altering the restrictor size and solve boost spikes.

 

That´s the one. Thanks alot.

No problems btw. Just curious.

I must try not to ask so much and use the search instead.
Wish I wasn´t so lazy.
