Looks aren't everything…but with regards to torque converters, they can hide the secret to winning races. For sanctioning bodies that mandate the use of a "stock appearing" converter, TCI Circle Track Torque Converters satisfy the rulebook requirements while delivering a distinct performance advantage. TCI Circle Track Torque Converters are specially designed with a lower "positive lock-up" stall speed, eliminating approximately 10% of the power robbing slippage found in OEM and lesser quality converters. On the track, this results in huge off-the-corner acceleration improvements and the ultimate in "green flag" starting speed. Built with a heavy-duty stator, furnace-brazed fins and precision-certified stall speed to maximize efficiency, these stock appearing converters usually reduce lap times by one to two-tenths of a second. In addition, these converters feature reduced rotational weight to improve engine braking in corners and lower transmission operating temperatures. Can reduce lap times by up to two-tenths of a second. Reduced rotational weight improves engine braking in corners to lower transmission operating temperatures.
