The operating RPM range is idle to red line. Thats what it was built for. There should be no problem when operating this equipment in the recommended range. If the equipment is not to be operated in this range , the factory would have reduced it. Thats why the red line isn't 9000.
OPINION
I believe its not the fact that you go to red line - its the rate at which it is done. Always flooring it to red line will cause a problem.
