Re: let make a car specific thread(dsmers)
Maybe some of you high boost guys can help me. I'm having troubles hitting more than 30psi. At the track, with the profec B vacuumed to the side port, I could only achieve 26psi. I pulled the vacuum port off completely, and plugged the vacuum line and hit 30psi.
Why one earth wouldn't it be more than this? I figured by pulling the vacuum line, it would essentially create a blockoff plate and the wastegate will never open causing the highest possible psi.
The tial 38mm has 2 springs in it. Psi was datalogged through an aem 3.5bar sensor.
Would routing the profec b to the top port, and setting it up external really achieve higher psi levels? I can't imagine this being the case but maybe I'm wrong.

I've never used a Profec B but I did have a e-01 which I would think would use the same principle on the solenoid. If thats the case vacuum is not keeping the waistgate closed boost is. Now that's based on an internal waistgate and what I remember from 3 years ago....
If I remember correctly if you want the waistgate to stay closed and spike boost as high as it will go you run a vacuum line directly to the waistegate with no boost controller and it will. If you do this the boost is cycling back through the vacuum line and equalizing pressure on the waistgate keeping it closed.
I know that does not solve your problem but maybe it helps...

Re: let make a car specific thread(dsmers)
How do you have the gate(vacuum wise) hooked up Andrew? Internal or external style?
Also, is it the original profec-b or the newer spec 2?
If you want the wastegate to never open just put a vaccuum line on the top port, it will hold it closed. Be ready for 4-45+ psi though(good luck gettin Eagles to hold that more than twice!).
The original profec B I'm thinking was only good for roughly 28psi..?
If you hook it up external style(using both top and bottom ports) then you have better control and can raise it more.
Also, if you don't hook anything up to it at some point it will blow the gate open when the pressure in the manifold over comes that of the springs.
