Hey Guys, I got a quick question. I've accidentally hit the rev limiter or fuel shut-off in my C6. I know that it is design to protect the motor from over revving.
I revved too high once cause I had just driven through some water and was pulling out into traffic. Another time I hit it just because of stupidity not shifting soon enough.
Do you guys think there is any damage that could have occured from those two occurances?
Everything sounds fine but I'm just worried cause I love my corvette.

If it means anything, I have hit the rev limiter and fuel shutoff in my '96 LT4's like HUNDREDS of times.
It's there to protect you. Although you don't want to drive the car pegged and banging off the rev limiter all the time, hitting it should cause you no ill harm (sustained hitting it though for a few minutes might cause some grief though... I dunno). Certainly nothing to worry about if you have hit it only twice. I'm sure the C6 offers the best protection yet against accidental engine damage.
Don't sweat it.

when I was 19 one of my favorite things was powershifting my '68 Camaro 350hp 396. The Muncie linkage was junk and the 2-3 shift could be missed but I never did miss it. It was easy ...just hold the gas hard on the floor , jab the clutch, and shift in a fraction of a second.
I didn't know about drive line loops, scatter shields, or other safety stuff and rev limiters didn't exist so far as I know. I really did enjoy power shifting that beast though.
I'd say the rev limiter is there to protect GM from having to replace mass produced motors that won't hold together if over revved. Together with the "head up display" ( some call it the heads up display but my title for it is more descriptive of my opinion of it ) and traction control, the rev limiter makes shifting the new vette just about idiot proof. Heck with CAGS you don't even have to know where 2nd or 3rd are........
my .02 worth is that if a person knows how to shift his car ( or in a zen sense is one with his car etc ) he would NEVER hit the limiter. So for those who do I'd say learn to shift your car better or maybe get an automatic or maybe drive an older car that's not been idiot proofed.

Whilst it is obvious some of us here have a harsh view of others skill levels I think that the fuel cutoff installed in ALL GM vehicles is a fine device and reagrdless of your proficiency with a manual trans should not be an issue, if you want to bounce off the limiter, or grind gears etc...by all means do so....my only advice is dont make a habit of hitting the cutoff while your engine is still "green" the fuel cutoof is just what is says...it stops fuel, not spark and as such it allows your engine to run VERY lean for minute periods of time...excessive operation like this COULD shorten the lifespan of the engine....IMO though you have nothing to worry about....and in the end even the mighty C6.R has a rev limiter....hmmm:thumbsup:

There isn't an engine built that will hold together if over-revved. That's why its called OVER revving. Any rotating mechanical assembly has a limit. The rev limiter (or governor) is designed to prevent the assembly from catastrophic failure. It isn't a reflection on skill or Zen. If you race enough, you will eventually miss a shift.
Rev Limiters were available as aftermarket items in the late 1970's from MSD to use on MSD ignition systems.
I don't know if the transistorized ignition system on the mid-sixties Vettes had rev limiters or not. I do know that 1970 era Boss 302 & 428 Cobra Jet Fords came with rev limiters (~6100 on the 302, and just under 6000 for the 428). A rev limiter is like any other piece of protection for an engine - you install it to prevent mechanical damage.
If you had missed one of those many wide open throttle shifts with that 396, you would have wished for a rev limiter! I've seen lots of big block engines turn into big piles of scrap iron because they were turned beyond their capacity.
I'm glad that GM has engineered this kind of protection into the engine - the electronics and software capability make this a reasonable and easy adder, so why not do it?

You are kidding... right? No offense, but we see "hand made" motors disintegrate all the time here on digitalcorvettes... lots more than stock "mass produced" motors. REALLY REALLY REALLY expensive motors. Crate motors... you name it. BANG. Gone. Oil and parts everywhere.
Gosh. Your amazing. Please tell us how you do it so amazingly.my .02 worth is that if a person knows how to shift his car ( or in a zen sense is one with his car etc ) he would NEVER hit the limiter.

it was to stop valve float /kinda safe gaurd against
swolling a valve intake or exaust /retaining clip might break and piston eats valve /piston hits valve /ristpin snaps on and on

Thanks you guys and gals. I feel better now. I love driving the corvette and don't want to have any enjoyment taken away because of some little thing like that.
So, I'll just sit back and relax and keep on :devil:
