Good try... but many people have experienced failures with them in boosted applications. Are you really going to take their testimonials as proof they work? Do you think they are going to put up bad product reviews on their own website? Forced induction engines put a lot of strain on the combustion ring. Think about it for a second, the overlapping section has to be half the thickness of the rest of the ring. Check with reputable companies that build high power VGs. None of them use these rings.
