I understand your logic, but it doesn't make logical sense.
I'm only talking about the 4 more revolutions per second that my car can possibly 'wear more' because of. That is the difference between my redline and rev limit. This is the highest cap on the RPM that the engine can 'wear' so there is no argument of 'what about 7500 its only 8 more revvs'.
Plus, Im talking absolutely with respect to the engine from 0 RPM. Which means 7000 is 2x more 'extra wear' than 6750 rev limit. 7500 is 4x more. So, my logic only works for the absolute difference between your cars redline and your cars rev limit.
Over the span of 10 years, my 60 mile round trip would put my crank revolutions right around:
60 miles, going 75mph at a total average door to door of about 3kRPM =
144,000 crank revolutions a DAY
525,600,000 crank revolutions in 10 years
Say I hit the limiter instead of the redline 5 times a day (upper end, worst case):
20 extra revolutions of wear a day due to rev limiting
73,000 extra crank revs over 10 years due to rev limiting instead of red lining 5 times a day
The extra revvs account for 0.013% of the cars total revvs over a 10 years period.
If you take into account the non-linearity of wear at the higher RPM due to hundreds of other phenomena, probably still fine, and this is at 5 times a day.
