How often do you hit the rev limiter?

Manual mode, fella. You'll touch the top of the tach then.

Never! Doesn't do the engine a bit of good. I often take it to 5-6,000 RPMs though. If I really stole it, I wouldn't want to draw that much attention anyway !

Sometimes, but I tend to say bad words because I think it is lousy technique. My target shift point is 6k unless I am on a long straight road in upper gears. Then I want every RPM. Banging the rev limit probably doesn't do much harm but it is certainly not "fast" either because we are effectively stalling the motor momentarily.

Harm usually comes during a downshift in the heat of battle and zinging the throttle too far to match revs. If stretched rod bolts don't get you, cavitation of the oil pickup and subsequent oil starvation will. I suspect most BSR race car motors are damaged or killed during over-rev downshifts... especially after a long left hand banked sweeper when most of the oil is in the right front head instead of the pan.

Anybody that has ever done any racing knows of what we speak. It's a red mist thing and our respective repair shops thank us for it.

Never. The engine doesn't want to go past 6000 and the power falls off abruptly thereafter anyways. I say all of this based on 'how it feels'. I've heard you should shift at a point where the following shift finds the torque peak- makes sense but I trust my ear. Now racing is different...

Oh and BTW don't forget these engines have oil starvation issues...

If you really want to over rev an engine and get away with it buy a Honda!:chicken:

That is where I shift, 5k - 6k.

When just driving (fast of course), what rev do you keep it at? I usually shift until I have the RPMs around 3k.
