Racing Beat-designed RX-7 flywheels are both engineered and manufactured by Racing Beat for a wide variety of rotary performance applications. This Racing Beat Lightweight Steel Flywheel can be used on all 1983-92 RX-7 13B non-turbo engines. As designed by Racing Beat, thisRX-7 flywheel is compatible with all 1983-92 non-turbo 225mm Mazda Factory and Racing Beat clutch discs.
Applications
Designed to retain enough mass for comfortable standing starts this Racing Beat flywheel is ideal for street use, yet it is sufficiently lighter to afford a noticeable improvement in low speed acceleration and to make shifting much smoother. For street use our lightweight steel flywheel not only allows the engine to accelerate more rapidly, but it also eliminates much of the rubbery feel that occurs at clutch engagement while shifting.
Precision Machining
Precision CNC-machined from high strength steel, our flywheel assembly is mated to the Mazda OEM ring gear, then surfaced hardened using a ferritic carburizing heat-treating process, creating an extremely durable disc wear surface. The ring gear is thermally-mated to the flywheel and bolted in place for added security to prevent slippage during engagement of the starter motor.
Weight Comparison
The weight of the stock flywheel is 23 lbs., compared to 13 lbs for the Racing Beat Lightweight Steel Flywheel. The actual reduction in inertia from stock is much greater than the weights suggest, since the stock flywheel is 1 to 2 inches thick at its outside edge.
Retaining Critical Engine Balance
The installation of an aftermarket flywheel requires the use of a Mazda rear counterweight unit to ensure critical balance of the internal rotating assembly (engine rotors). As produced by Mazda, the original stock rotary flywheel features a pronounced balancing mass included in the flywheel casting. This balancing mass, combined with the stock front counterweight unit, provides the correct balance required for the optimal rotational operation of the engine rotors.
To allow an aftermarket flywheel to be used on several different rotary engine applications, this balancing mass is eliminated from the design of the rotary flywheel. However, this critical balancing mass must be replaced with an alternative balance weight or risk severe engine damage due to an “unbalanced” engine. A convenient alternative is to install an appropriate rear counterweight from an automatic transmission-equipped RX-7. Racing Beat offers this counterweight separately if needed.
