I compared a Fast 92mm vs Fast 102mm on a factory LS3 intake using an adapter. The tapered adapter allowed installation of the larger-bore 102-mm TB on the 92-mm throttle opening on the LS3 intake. The test motor was a 2008 LY6 with a healthy Comp cam, headers and the LS3 intake. Did the 102 TB/adapter add any power over the 92mm?
