Some people have had problems with the standard ABV leaking under high boost levels.
Some people also have far too much money and feel a strange need to spend it on fairly pointless billet aluminium thingies...

I cant imagine how an aftermarke blow off valve would work on a GZE anyway, as the supercharger is AFTER the throttle body, so there's nothing to build pressure against!
i'd say he's a victim of excess cash and a love for shiny "go fast bits"

i will always say that replacing the ABV with a BOV is a useless activitiy........ it is always on the vacum side of the throttle body (unless you have relocated the throttle body) if you are leaking boost through the ABV, take it off altogether, i have done this when i had the ze, (and a lot of ze owners in UK have done the same), the s/c has a clutch so it does not harm the performance/engine in any way, by not having the ABV. some of them have even taken the venting system off the top of the s/c, and just joined the three vent pipe together, as boost has been able to escape through them into the throttle body (well above it where the pipe goes in).......this does not harm the s/c.
