More Vigor for the Viper

Written by editor on . Posted in Fall 2009

Mike Briggs of BBK Performance says you can get an extra 10 hp on average from your 2003–2006 Viper engines (including Ilmor marine applications) by replacing the 62 mm factory throttle body with a 67 mm piece from BBK. Briggs sent along some photos showing how to make the change. We have not tested it, but would welcome your comments if you try one out. Send your cards and letters to the editor.
