Hughes Performance Pro III Series torque converters are available in several configurations and are among the best-known full competition units. Literally thousands of these units have been produced, and when repeatability is important, these are the converters most people insist on. The prime characteristic of the Pro III Series is the hard launch, but soft transition down track, allowing more consistency and ability to repeat. In many cases, variance of 60 ft. times will only be a few thousandths from the first to the last round.
