Isn't this what I said above

 

Some yes...Tenblade asked me to come over and throw in a post about retainers.....

 

Racer, I agree with you, but at the same time, wanted this guy to differentiate (1) the bounce or tap on the rev limiter vs (2) the over-rev from downshifting; one is ok, while the other can damage the car without you knowing it.

 

I hit my rev limiter today... I tend to hit it more in 2nd than any other redline situation ...my04 seems to just wind out fastest in 2nd gear and with some distraction (or focus on the road ahead) from the shift sequence I hit the limiter in 2nd gear ( for a brief moment)

btw - I also whacked my map sensor today and then tied it up with a zip tie ....

oh what fun i've had today!

 

This is what I said, except an over rev caused by downshifting, otherwise known as a mechanical over rev, if at too high of a speed for the grear, WILL toast the engine

 

I forgot to post my smiley

 

Isn't it true that driving the car and NEVER going over 6000rpm can actually cause problems down the road?

I thought there was a technical post on this, something about buildup of some kind.

 

If you over rev due to a mechanical over rev just a little bit, there may not be valve to piston contact, but damage can occur to the retainers. The more the engine is forced to mechanically over rev, the more likely the piston to valve contact is to occur.

Thanks billman for your interpretation of this scenario

 

yes this is very true!

you get carbon build up in the piston area if you do not your car to its 'red line', this in the long run basically ruins the engine and wastes your money....

generally this most often happens on motor bikes though. the youths like their bikes sporty but have to have them 'neutered' (limited) to under a certain RPM as they arnt old enough to have the full power band...
i know this because a friend of mine a while back when the ninja just came out (rich git) brought one and he had to have it limited, poor poor bike it ruined the engine so he sold it.

 

What if an engine is turbocharged? Is hitting the rev limiter bad then?

I think I've read somewhere that it's bad to cut off the fuel supply to a turbocharged engine at high PSIs.
