cool porsche gt1 kit car starts up than accelerates in the second link http://videos.streetfire.net/video/911-GT1-LOUD-START-UP_210901.htm http://videos.streetfire.net/video/911-GT1-LEAVES-CC_210723.htm
did not ask the guy about that..great question though. he told me he worked on it himself..including the engine which is actually a v8 (original gt1 was a flat 6). quite an interesting car.
With so many cheap 996 turbos out there he should have used one. It has the same block as a GT1. Really.
