I don't see them too often, but they are used on a number of factory cars and Greddy and I believe HKS sells one.

But (in theory at least) they are the best way to protect against overboosting/spiking.

You could probably score one easily at a junkyard and it would be cheap insurance.

Anyone?

I need to be educated too! I read about it on the Greddy site, but I still don't understand. Please help a confused individual!!

A pop-off valve is similar to the pressure relief valve on a N2O tank. Some what..
Once a maxumim pressure (in the intake manifold) is reached, the valve bleeds off pressure to stop an over pressure danger.

N20 tank relief valves release excessive pressure by breaking a small disk and venting out all of the N2O gas from the tank. The disk has to be replaced inorder to use the tank again.

Pop-Off valves relieve intake manifold pressure but I have seen smoe models that use a similar disk method and others that use a check valve system. The check valve is reusable after the excessive pressure contition is gone.

Fill in some info fellas, I'm sure I missed something?
