Was passing yesterday on a two lane road and went for fourth but ended up with second. As you can imagine the revs built real quick, now I am hoping the rev limiter kicked in, I assume there is one. Does it work by restricting the gas flow and at what RPM? I do not think there is any permanent damage, car has 2500 miles and is a 06M.
I'm wondering if there is anybody here with an M6 who HASN'T done the same!
I did the same twice, once in the first week while schooling an Integra, and once at the track while upshifting for a long straight away. In both cases what saved me was a quick clutch foot and the lousy traction of our relatively small rear tires! I'm happy to say at 12,000 miles so far it looks like the drive train has held up.
Symptoms to watch for include valvetrain tapping noises from over revving, exhaust smoke, or knocks from the motor from throwing a rod. Clunking in the driveline from damaged U-joints or halfshafts.
Bottom line is if you hurt it you would most likely already know! Just slow down on the shifting, at least until you really get used to the slow shifter, let the LS2 power do the hard work and keep enjoying your car.
