  • Does an RPM Limiter Affect the BOV?

    An rpm limiter will not affect the BOV (blow off valve) because, like the rpm (rev) limiter, the BOV is there to protect the engine and its components. As the engine approaches its “red line” revolutions, an rpm limiter reduces fuel flow and spark in order to reduce the engine’s rpms down to a safe level. When the sudden reduction in rpms occurs, the BOV will prevent back pressures from building within the turbo, thereby preventing damage to it. The rpm limiter’s forced rpm reduction is (basically) no different from the driver releasing the throttle.
