Forces increase dramatically with rpm—for proof, consider the Ford engineers when the Coyote clutch pressure plate and flywheel kept vibrating apart at high rpm. They had to safety-wire the clutch bolts to keep the pressure plate in place during testing. The production cure was to go from six to nine pressure-plate retention bolts in an oddly staggered pattern. Otherwise, the flywheel follows Coyote practice, with eight bolts at the crankshaft and neutral balance. At the other end of the crankshaft, the harmonic damper is uniquely balanced for the Boss 302’s high-energy torsional vibrations.
