Don't know if he still feels the same way nor do I know of any statistical study on the subject.
its a good theory, more RPM's= hotter oil (condensation being burned off) and higher oil pressure (oil getting pushed into all those little crevices)

I try and keep my RPM's above 3k as much as possible and have run it to the rev limiter a few times in 1st and 2nd

but Im still planning on doing the IMS upgrade with my tax return this winter/spring
