8in Turbo Race Converter

The COAN 8in Turbo Race Converter (Part No. COA-20504) is a high-performance torque converter engineered for serious transmission tuning and performance applications. This 8-inch diameter unit features a 10.750-inch bolt circle and spragless design, making it compatible with TH350 and TH400 transmissions. Built for drivers who demand precise torque multiplication and responsive power delivery off the line, the Turbo Race Converter is a core component in performance builds where transmission efficiency directly impacts acceleration and overall drivetrain reliability.

The spragless design eliminates mechanical drag inherent in traditional sprague-based converters, allowing smoother engagement and reduced parasitic loss during cruise and part-throttle operation. At 23.22 pounds with compact dimensions of 13.7 x 7.75 x 13.75 inches, this converter balances effective torque management with practical installation geometry. The 10.750-inch bolt pattern ensures direct fitment to TH350 and TH400 bell housings without adapter complications, critical for builders prioritizing bolt-on compatibility and reliable bolt-down torque retention under load cycles.

Ideal for street performance, bracket racing, and small-block engine combinations running GM automatic transmissions, the COAN Turbo Race Converter delivers the stall characteristics and lockup behavior expected by builders stepping up from factory converters. This is a single-unit purchase, allowing incremental drivetrain upgrades or direct replacement of worn units in existing builds. Buyers integrating this converter should verify current transmission condition and confirm bell housing compatibility before installation to ensure optimal performance and longevity.
