Hi,

So my project car is coming to the end. I got an mot. But I noticed that it was running very low boost. 0.2 bar.

I put in the bleed valve...no matter what I done...It still stays at 0.2 bar....

So I decided to take the vacuum pipe off of the actuator to see what happen...

It boosts up fine but I was letting off at 0.7 bar. (This boost pressure if fine for my spec)

Question is... If I leave the pipe off. What's the max psi it will hit?

Am I right in thinking that 12 psi is what it will go to with it closed like this? And that a standard actuator only hits over this with a bleed valve put in.

And that a -31 would run 1 bar without the need for a bleed valve?

Thanks
