So I've been enjoying the joy of second cam more and more often, but always in short bursts. How long can/should I stay at 6200-7000rpms before my engine goes *poof* -eek-

Thanks.

Your temp guage will tell you if your asking for problems, (if it starts going up, slow down).

But the time you can run @ 7000+rpm is probably measured in minutes, if not hours.

This is assuming that you have a well maintained car, (Check the oil!!!!)

Most of the poeple that track these cars probably stay within the meat of that section durng most of the session, I know I have with my limited track experience. So your talking anywhere from 5 to 20 minutes right there.

As mentioned these cars have excellent cooling capabilities (both oil and water as well as overall engine bay), and hopefully you are keeping the oil in good shape.

Spirited street driving, you are posing absoluty no problem to the car. I often cruise the highway in 5th, so thats right around 5000 RPM at around 80. The answer that your ultimatly seeking is that you can just install a supercharger and not have to bother about the upper RPM's anymore :D

I have read that the low rpm cam rides on roller bearings while the high rpm cam uses a slider. I would expect that the high rpm cam will wear much quicker than the low rpm cam. Your short burst would be best for longer life.

i keep it arund 6k-8.5k on the track for 15 -20 mins sessions.... this engine can rev all day long... g's... now maybe thats a different story....

ther have been some cam issues - but it seems to not be from revs, rather some defect parts on some cars.

i am a high rpm user for over 4 years :clap:

I'm not sure I understand the question.

Condition A: If you're just cruising, use the gear allowing the lowest rpm necessary to maintain your desired speed. No sense running around at 7000 rpm all the way from your house to the Walmart.

Condition B: If you're accelerating, you maintain high rpms until it's time to shift, then you do it again until it's time to shift again, and you keep doing that until you reached your desired speed and you're ready for Condition A.
