Rev Limiter - is there one?
Discussion
Have done some spirited recently and I was wondering is there a rev limiter like on 'normal' cars?
What is it? Is it a hard limit (ie you suddenly loose power)?
Will my engine eat itself if I hit it?
If the answer might be yes can I manually lower it to something I can bounce off?
Sorta scarewd of venturing up there at the moment.

I've only hit the limiter once or twice before, to be honest there isnt much more power to be had past 7000/7200 rpm anyway (on the 4.0l cars)
It wasnt pretty when I did hit it, sudden loss of power/acceleration, nearly headbutted the steering wheel, followed by a sudden burst of acceleration again. All happened quicker that I could lift my foot off the loud pedal!
I have my change up light set to red at 6000rpm now, makes for a bit more mechanical sympathy and phycologically I think Im ragging the nuts off it as I go "into the red" on a regular basis!
Always cool seeing the red shift up light too! except when its dark, its so bright it blinds you a bit!

Most 4.0 cars, there is a limiter at around 7750rpm. The 3,6 liter cars I have driven, the limiter is around another 500 revs higher.
Don't go there too often and ensure all is serviced well and the revs are used when oil is hot 70 degrees + and it should not be a huge issue.

Mechanical problems aside the speed six must have been truly impressive in its day!!
Where is the max torque?
