The data here is for an '01:

RPM rev over limit is set at 9,200 RPM and is controlled by the ECU.

VTEC is controlled by a solenoid which will not open above 6,400 RPM unless certain oil pressure parameters are met. The reduced viscosity of the oil allows these pressures to be met when the water temp is showing ~3 bars. Actual water temp is irrelvant to the engagement of VTEC. The key is oil pressure (see your Helm manual).

There is no overlimit protection for a "high" downshift. This is where most damage (ii.e. bent valve stems) occurs.

Check your oil frequently.Keep it on the high end of the stick. Good luck with your ride

 

This is the best advice you'll get about the s2k. It will burn oil, and you will fry the engine if it gets low. I've done 3 engine jobs for this single reason alone. You do not want to know the cost

 

Then why have I never seen a dyno plot out to 9200? Every one I see barely makes 9000.

 

Although I still haven't maxed out on my RPM range yet ('05 S so 8300) I've always been assuming that when upshifting I could bounce off the 8300 RPM rev-limited point all day and no damage would occur. Is this correct or does one still need to be careful with upshifting at or near the rev limit?

 

dyno plots are often off by a couple hundred rpm.


i've had data capturing devices that showed my rev limit is around 9140-9150

 

Rev limit is actually 8200. I have a separate digital tach/shift light that records highest rpm and it's definitely 8,200. Actually, I hit 8,210 to be exact.

Anyway, the rev limiter is there to protect your motor and as long as you don't mechanically overrev by a missed shift, you could theoretically bounce off the rev limiter all day, though the high revs will cause increased wear, of course.
