TNT492 – 92mm T6 Journal Bearing Turbocharger

Need a 1,500+ WHP capable 400-frame journal bearing turbocharger for grudge racing, no-prep, or extreme street builds? The TNT492 has been redesigned with our all-new 92mm 12-blade billet compressor wheel, delivering an even broader powerband while maintaining the airflow required for four-digit horsepower.

Replacing our previous 7+7 compressor wheel, the new 12-blade design was engineered to improve response, increase operating range, and provide exceptional drivability without sacrificing top-end performance. Whether you're chasing ETs at the track or building a high-horsepower street machine, the TNT492 is designed to keep pulling hard throughout the RPM range.

The TNT492 features our proven 103x92 turbine wheel, developed through years of research to reduce the backpressure commonly associated with maxed-out GT50-based 99x92 and 102x92 turbine combinations.

The result is a turbocharger that accelerates the rotating assembly more efficiently, builds boost quickly, and continues flowing where many comparable designs begin to fall off. The combination of our new 12-blade compressor wheel and high-flow 103x92 turbine delivers the broad power curve and top-end performance serious racers demand.
