Actually, Turbotrix's Evo is running 9's. Not the mention there are numerous shops out there with Evo's running mid 11's on the stock turbo. In addition there are DSM's out there running 8's on the 4G63. So yes, while you will never find a dyno video of a single turbo 4G63 making 1200 horsepower, there is proof that it can still take cars just as fast as the RB.
