New Speed Inc. Twin Turbo 408ci dyno results
Speed Inc has a large portfolio's of custom turbo systems built on late model domestic vehicles. Dipping into the 8's in the 1/4 mile and speeding above 199mph in a standing mile. Built around efficiency and dependability, these vehicles can be driven regularly on the street. Advancements in dual stage fuel injection, large high impedance injectors, 3-bar programming for factory PCM's, and adaptable after market PCM's have helped each project obtain awesome power results while not being a 'race car'.
