    TCI Automotive 251200 Details

    TCI 9", 10" and 11" Drag Race Torque Converters can be run in applications with up to 750 horsepower and are most commonly used for a bracket race or street/strip application that leans more toward the "strip." Stall speeds vary depending on application but the average is 3800-4500 RPM for 9" and 10" converters and 3000 RPM for the 11" version. Furnace-brazed and reinforced fins increase durability. Needle bearings reduce drag and increase thrust capacity. Three sets of Torrington bearings replace normal thrust washers used in OEM and some aftermarket converters to triple the thrust capacity capabilities. Hardened steel pump hubs increase strength, durability and longevity while decreasing wear. Increased strength and holding capacity of high load sprags ensure stator stays locked when converter stalls and guarantees converter will stall correctly run after run. Ballooning plates (9" and 10" only) double strength of converter when using transbrake and/or power adders. 360 Degree Mounting Ring.

    This 9 in Drag Race Converter for 65-81 Torqueflite TH350/400 w/ Wide Bolt Pattern provides roughly 3800-4500 stall.
