BOV question

[woody]

How far do the plungers open on greddy bov's?
Mine will open only 4mm, I think it is defective, since it looks like it is designed to go about 1/2" approximately.
It doesn't jamb or anything, but barely opens.

Anyone know?

which model of greddy bov do you have? I believe alex (swegyptian) has the type-S... so might wanna pm him to know, i also know a couple other guys with greddy valves i can ask

It's almost impossible to see how far it really opens. Without the big CFM going (when sitting still), it's hard to get the turbo to spool. It should barely open when you aren't building boost. I'll try to check mine out in the next week or so.
