The rev limiter only kicks in if you are running up through the gears? Correct? I'm wondering ... my car doesn't sound good and I accidentally shifted into 3rd doing 110mph... (just sounds like its running a little rought, not shaking or anything) I HOPE IT HIT THE Rev-limiter, but I wasn't looking? So. am I correct, that downshifting doesn't allow the rev limiter to go into affect and that there could be some serious damage to my car?

Sure, it probably hit the rev limiter. But way too late.

If you miss a shift (hit a low gear) at that kind of speed, the rev. limiter ain't gonna help you much, unfortunately.
An ignition-cutout type rev. limiter really only works "on the way up," not "on the way down."
It is very possible to exceed the redline and do damage to your engine if you hit too low a gear, regardless of whether the ignition rev. limiter kicks in or not.
This is because the rotational inertia of all those engine parts moving (when you release the clutch & mate up that wheelspeed to the driveline in the low gear) is just too great for the ignition-cutout to slow all that movement.
Be veeeerrrry careful. Snap, crackle & pop, are sounds best left to breakfast cereals, not your Maxima's powerplant.

. Then add a good 10 SI of Super charged power into the mix, you get one very blown up clutch. Luckly the clutch blew and not my engine or tranny, thank god.

well if it is idling bad you better go to a shop and get it checked out. I went from fourth to second doing over 100 in my nissan pickup and it bent 3 valves and chip the timing chain.
110 in third aint tooooo bad. Most NA Max'x finish the 1/4 mile at just under 95mph. So you probably spun it up to ~7500-8000k. Id drive it a little while and see how it feels.
