Beware of rev limiters in classic cars

One of the higher priorities in the period 25-30 years ago was to design a rev limiter to work with electronic ignition and fuel injection so that it would be done more "softly," and prevent any harm to the motor, but if you happen to have an opportunity to drive an older Porsche or BMW which still has the centrifugal distributor rotor type of rev limiter, beware of gratuitously using the rev limiter as an "upshift" signal, because on those cars it can cause enough jerkiness in the motor to slap and snap the timing chain, or at least jam the chain tensioners. Of course, many of the people who bought such cars discarded the rev limiter at their first tune-up after the warranty expired in order to turn another 600 rpm when they felt like it anyway.
