Building huge horsepower is fine as long as your drivetrain is up to the task of delivering the power to the pavement. TCI offers a complete line of premium torque converters built exclusively for use in Top Sportsman, Top Dragster and 10.5 Tire Outlaw classes. Able to handle 500+ c.i., 2500+ horsepower, 3500 RPM applications (including multi-stage, nitrous-assisted, supercharged and twin turbocharged engines), these high strength torque converters are built for most GM, Ford and Chrysler transmissions and bolt up to either six or four-bolt mounting flanges. In addition, the PRO-X 9" and 10" Torque Converters utilize the state-of-the-art, proprietary metallic gray HDT Coating which enables TCI converters to operate at lower temperatures and cool down faster.
