How often should i run at high RPM

Make sure the oil temp is at 180+ before any high load operation, just to be sure.

Mechanically, your car does not need to be "exercised" to remain in top physical condition. In the old days (20+ years ago) when combustion was not nearly as good as it is now (especially with carbs), max output operation could help keep your engine cleaner- valve seats, head, spark plugs, piston crown, but this is not an issue with modern cars and fuels.

High load operation does put increased wear on the engine, which directly effects life. I do not know what the design parameters are, but our cars would probably run 400k miles without a problem when driven "mixed use", like an average guy like me driving to work and home every day, at normal traffic speeds. Yes, modern engines are really that good, and rather over-designed. If you run your car exclusivley on the track all the time, maybe the life might only be 100k miles. Bottom line, drive it however you need or want to and forget about it.
