I know Titan and AAP both run glides, paisly ran a glide in his car when he went 8.17 on a stock motor, john h is running one in his monster tubed supra, isnt saad saad running a glide also?

plus the fact that a pg is also lighter then a th400 makes it a more liked choice for the high hp guys. I could go search on supraforums for more info but I would probably say that as many if not high hp guys use a pg, but high hp street guys is a different story IMO.
