11in Circle Track Torque Converter 2000-2300 RPM

The 11in Circle Track Torque Converter 2000-2300 RPM by TCI is purpose-built for circle track racing and high-performance drag applications where reliable torque multiplication is non-negotiable. Designed for drivers who demand consistent power delivery off the line and predictable shift points, this converter transforms your transmission's efficiency by optimizing the fluid coupling between engine and gearbox. Whether you're campaigning a bracket racer or pushing hard on the oval, this 11-inch unit delivers the stall speed range needed to keep your engine in the power band when it matters most.

This torque converter operates in the 2000–2300 RPM stall speed window, allowing your engine to build boost and torque before the transmission engages—critical for minimizing launch bog and maximizing wheel spin control on a prepared surface. The 11-inch diameter design is engineered for intermediate to heavy-duty applications, providing ample fluid volume for smooth pressure rise and efficient heat dissipation during sustained racing. TCI's internal geometry and vane design maximize coupling efficiency while the stainless steel construction resists thermal stress and corrosion, ensuring durability across multiple race weekends and high-temperature track conditions.

Circle track competitors and street/strip enthusiasts benefit most from this converter's tuned stall range, which pairs ideally with stock to mildly modified powerplants running conventional automatic transmissions. Installation requires proper transmission pan depth and case compatibility verification with your specific trans—consult your build sheet or reach out to a transmission specialist to confirm fit. At 34.7 lbs, expect slight weight penalty compared to stock, but the torque management and launch consistency gains justify the tradeoff for serious racers aiming for consistent ET.
