i hope the bov from the evo 8 proves to be more efficent at higher boost levels. My buddy with an srt-4 runs a dsm 1g with about 28 lbs of boost....................no problems yet, just a really long blow off.DSM BOV's are loud. But when you're running excessive boost they arn't efficient. I'm piecing together a turbo kit right now and I went ahead and picked up a HKS SSQV. When I get it all together in 2-3 months I'll post up some video/sound clips.
