I run my engine near redline all the time, I have driven it from Co to Oh
a couple of times at no less than 4500 rpm for 20 hours straight, I love
it and my car loves it, but I do beleive that it wears bearings out
faster. I don't think that it does any real damage, just wears out the
consumable engine bits faster. The biggest advantages of an O/D are about
5 mpg better mileage and less noise, but less noise isn't always
desireable.
