Steel SFI Flywheel - Pontiac V8 166 Tooth

The PRW Industries Steel SFI Flywheel for Pontiac V8 with 166-tooth design is a purpose-built component engineered for high-performance engine builds and racing applications. This SFI 1.1-certified flywheel combines proven steel construction with external balance configuration, making it the ideal choice for builders seeking reliable power delivery and consistent engagement with racing clutch systems.

Weighing 31.15 pounds and designed for 2-piece rear main seal compatibility, this 166-tooth flywheel delivers the inertial characteristics necessary for smooth torque multiplication across the RPM band while accommodating modern multi-disc racing clutches. The external balance specification means this component integrates seamlessly into engine combinations already balanced for externally-weighted harmonic dampers and crankshafts. SFI 1.1 certification confirms this flywheel meets the safety standards required for sanctioned competition, providing verification that it has undergone impact and stress testing protocols specific to high-RPM motorsports use.

This flywheel is engineered for Pontiac V8 engine platforms where builders are upgrading to aftermarket clutch systems or rebuilding engines for street performance or strip duty. The 166-tooth count provides the mechanical advantage and starter compatibility expected in Pontiac applications, while steel construction offers the durability required for repeated high-load engagement cycles. Whether preparing an engine for bracket racing, weekend strip duty, or high-performance street use, this component delivers the reliability and balance characteristics that serious Pontiac builders specify.
