Does anyone use a popoff valve?
No, not a BOV, a popoff valve. My old 280zxt used to have one. When I was browsing a website looking for some fittings I came across Adjustable popoff valves. Our cars don't have them, it might be a good idea to run one.
Basically what it does is vent manifold preasure once it gets past a certain preasure. It doesn't allow you to run higher boost, and the only time it makes a WhooosH sound is when it saves your engine, but its a good safety mod. If you get a spike in boost preasure it vents it to the atmosphere instead of blowing your apex seals.
If you goto www.mcmaster.com and search for 'pop-safety valve' there is some good information.
