Digital Rev LimiterA rev-limiter is designed to prevent over-revving your engine. All late model Porsches include a rev-limiter included in the engine management system. Destroying an engine by shifting into too low a gear that tries to force the engine to operate beyond design parameters has become a thing of the past.
Speaking of the past, can this protection be added to older cars?
Yes, the product that is often used in the vintage racing community is the Pertronix Digital Rev Limiter.
Normally a street car would never need to have a rev-limiter. But what if you are paranoid about damaging an expensive rebuilt engine? What if you are considering auto crossing the car?
