I’m just playing around tonight in the garage and I wanted to see what the little PPE valve actually does. I was pretty surprised, maybe everyone knows what I’m about to share and I’m just catching up, lol.
The valve ALWAYS leaks boost. There’s a small orifice that leaks boost immediately. I turned my regulator down to a Lb and it was immediately leaking. I didn’t expect that.
The stock setup has the wastegate creeping open as boost rises. The valve seems to bleed off until break over and then it activates the wastegate slowly. I expected more of a blow off effect, so that was a surprise too.
I have videos if there is any interest in seeing this as it happens.
