I know the Rev Limiter is in the engine ECU to protect the engine from over revving, but is it bad to hit the limiter? Just a FYI to those that are unfamiliar with rev limiters. It's the point when you redline the car to it's redline limit before shifting to the next higher gear. The car will jerk because the computer cuts the fuel to prevent over revving.

Its not great but on some autocross courses guys will bounce off the limiter for a second or two if there's no time to get a shift in before a corner. No harm done.
Don't do it all the time but if your motor is healthy otherwise its not a big deal.

I think it's bad NOT to hit it. That's why it's there. Enjoy the ride!

The redline limit of the motor isn't the same as the rev limiter. IMO, if kept with in the rev limit, motors are usually killed by underlubrication, over heating or excessive time at high load/temp, and cyclic heat loads such as warming up a car too quickly (think rallying your car to work every morning from a cold winter start.)

It is not bad to hit the limiter once in awhile, but revving your engine that high on a long term basis will cause wear and damage. Just like it does not hurt to use your anti-lock brakes, but they are not intended to be used all the time, it would be hard on the brakes.

Wholeheartedly agreed. Use the entire RPM range possible. Try not to have it pegged at the limiter all the time but getting it up there occasionally is good for the long-term engine health.

... and if you drive a rotary, it's actually a requirement.

Some vehicles, although likely older, can still float valves even with a rev limiter.

the rev limiter IS the real redline, and there is no way that a stock engine in good mechanical condition will be harmed.

The redline is the design limit at which damage could occur. The rev limit is not the same. Agreed that there is no way that a stock engine in good mechanical condition will be harmed. Going along with what BeanCounter said, I wouldn't trust my old Subie with 205kmi on'er at rev limit RPMs for very long, though.

Do 5 hard ABS stops from 60mph and open your window. You will smell your brake pads, and you've probably just taken a few thousand miles of life out of them.

Yeah thats funny right ? The only time my anti-lock brakes kick in is in the snow. And that shouldnt be hurting them.

No, the odd ABS usage in snow is probably good to keep things from siezing up. Ice racing with the abs on probably would wear out something in the system eventually.
