Just got 300 C SRT8 last week. Driving slowly for 300 miles as recomended. Howver at about 250 miles, I inadvertantly left it in first gear and reved engine pretty hard, mabe 50 mph, not sure if tach red lined, but believe it red lined or got close for about 1 -2 seconds.
No obvious problems, but I am not a mechanic. Did this over rev during late break in do harm that will not be immediately apparent? Hurt oveall engine life or performance? Again, nothing noticable, but wondering what are the effects if I went past the red line?

Appreciate feedback from those knowledgable about reaching red line before break in period was truly completed. Is there a rev limiter on this model to prevent over revs?

Regards,

There is a rev limiter at about 6500. It'll fart and splutter while you try to get it into second gear. It is largely useless to Autostick for racing. See other threads. There should be no damage to your engine or drivetrain whatsoever.

Cheers!!

My race car engine builder/mechanic friend tells me that with newer engines the machining process has improved so much that you don't have to be nearly as careful during break in as before and that even driving like a madman from day 1 probably won't do much harm (he also noted that on the race cars he just runs them for a couple minutes to warm them up and that is the extent of break-in). I guess this is evidenced by my car (1985) says 2000 miles, the next car (1994) said 1000 miles, the next (1998) said 500, and now we have 300.

appreciate your insight

A quick note to say I appreciate the insight from your responses. Reassuring to here opinions from experienced folks that this mistake did not hurt the engine.
This site is great. Looking for threads about the autostick not being that great for racing, but did not find them.
Did find thread on break issue (dust on wheels) which I have also noted, as well as thread on intermittent lifter tic at low idle, which many owners also noticed, but most of the experts stated is not a real issue.
Look forward to hearing from you guys. Can you further enlighten me on the manual shift and why it is not overly effective for racing?
Many thanks,
Bigrick

You didn't hurt a thing. Don't worry about it. The rev limiter won't allow you to overrev your engine.

In fact, brief wide open throttle runs to shift point are what is part of the break in period. You actually SHOULD do what you did once in a while.

Don't do it everytime you drive it.......otherwise it's actually a good thing to visit the upper end of the tach every so often. you should be fine :)
