11 Inch Drag Race Converter for TH350/400 w/ Small Bolt Pattern.

TCI 9in, 10in and 11in 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 instrip.in Stall speeds vary depending on application but the average is 3800-4500 RPM for 9in and 10in converters and 3000 RPM for the 11in 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 (9in and 10in only) double strength of converter when using transbrake and/or power adders. 360 Degree Mounting Ring.
