CorvetteIn the forthcoming Le Mans 24 Hours event, June 14-15, Corvette Racing has much reason for optimism. Their new C7 machine has won the last two rounds of the GT Le Mans class of the Tudor United SportsCar Championship held at Mazda Raceway (Laguna Seca) and Long Beach.

But for road-going Corvette C7s Ram has introduced two new clutch-flywheel assemblies to manage the full potency of power adders delivering up to 1,000hp and beyond.

Necessity with power adders

-Organic disc series transmits up to 800hp

-Metallic disc series transmits up to1,000 to 1,100hp

36dRam-ZL1ClutchColumbia, SC: As sales of the new C7 Chevrolet Corvette build, Ram Clutches has developed two new 10.5in dual-disc upgraded clutch–flywheel systems. They are devised to transmit the increases of aftermarket power adders: potent superchargers, turbochargers and nitrous oxide.

Consider the proposition offered by Ram. Identified by their greater clamping power, the new clutch systems are direct replacements for the original 10in dual-disc clutch and dual-mass flywheel. Consider also they demonstrate lighter weight and transmit the added power output effortlessly through the pedal. The increased clamping capacity is generated by greater static pressure and the use of two advanced friction materials: 300 series and 900 series.

When used with conventional tire compounds, gearing and weight, the 300-series—an organic friction material—transmits up to 800hp. The more aggressive 900 series, a metallic base, transmits up to 1,000 to 1,100hp. Both systems are supported with urethane encapsulated springs, which resist four times the compression rate of uncoated springs.

Ram’s new cover assembly, which is equipped with a nodular iron pressure ring, comes with the promise of generating clamping pressures of 2,400psi to support the greater torque loadings.

Importantly, a special billet aluminum flywheel is provided with dimensions that properly position the clutch discs on the OE transmission input splines. Perhaps the more appealing prospect is that of lighter mass. This new flywheel-clutch assembly (PN 80-2112) weighs 50lbs compared with the factory original at 65.5lb.
