Main bolts hold your crankshaft in place. When you get more horsepower and RPM than your engine was rated from the factory for Original Equipment, you are beginning to push the limits of the factory fasteners.

Factory fasteners were not designed for performance use. The material selected by the original engine manufacturer for your engine's factory fasteners has been selected to meet the criteria of a normally powered consumer vehicle at the specified bearing rating and RPM. The material is not optimal for a high-rpm, high-heat, high-power race car.
