So I have a vauume distribution block where the boost signal come in for my fuel pressure regulator, and for the bottom of the gates.

However I started to hook up the solinoids for the boost controller and was about to run the line to that block as well, but I got to thinking that the vacuum might suck the gates open. But then I also thought well the same vacuum would be getting applied to the bottom of the gate so it would cancel each other out.

Anyone have gates hooked up like that?

Thanks!

I would never hook up wastegate plumbing to the same small diameter feeds as any critical things like FPR or MAP sensor signal.

Boost control via the gates/solenoids will bleed air off, this is an air leak which can lead to a false signal at the FPR or MAP sensor etc.

Yeah good point...

This is where I'm getting gate pressure.
Works well, is convenient (if not running pcv, catch can etc) and is ahead of the throttle blade.

I didn't know that was a vauume source. (Well pressure in that case) thought that was a coolant passage.

Guess I need to cap that off. Thank you.
