    My 99 Z28 came with a speed limiter of 160mph from the facotry.

    Cars that came with Z rated tires didn't have one... I think it just shut the fuel supply off when you reached a certain RPM in your final gear.

    Cars without the Z rated tires (V6's and some Z28s) had a limiter... Not sure on the exact speed... But I think it's around 115?

    I'm pretty sure all newer cars come with factory rev limiters. most of the small 4banger imports don't need a top speed limiter because their lower power output makes them hit a (brickwall) as far as top speed. (resistance works as the limiter) but most of the larger displacement/ hi output imports still run topspeed limiters
    ls1powerhouse is right the "rev limiter" for us is a rpm set fuel cutoff

    there are both speed limiter stops your car at a certain speed. most sports cars are around 140 to 165 trans am , vettes, camaro, etc....
    rev limiter stops your rpms at a certain range so you dont hurt the motor or warranty issues such as stock our trans ams stop at 6 grand but with a tuner or tune i have mine at 6600 and thats mild could do more

    just a warning, with stock valve springs you can run into valve float as low as 6,200....i have mine set at 6,100 just to be safe

    ok cause ive taken it up to 125 but didnt really know how high i could go before it would kick in. so im basically good till around 160? is there any problems to the car if it kicks in? or it just causes u to slow down and the car starts working again normally?

    oh you will be able to tell when both the rev limiter and the speed limiter kicks in. you have a z28 so i dont think it kicks in till about 155 or 160. so i think you will be good. all it will do if you do get there is you will feel you car jerk a little bit for you to know to let you foot off the pedal it wont let you pass that speed unless you get a handheld or tune to stop all limiters

    No, convertibles have a low cutoff; like 112, most everything else is 160.

    Don't confuse RPM based rev limiters with the speed limiter; they are different as well.

    To the poster spinning his stock sprung setup to 6600; not only is that WAY past your power band, but you are in serious engine jeopardy territory. As noted; stock springs float very low; much lower than 6600.
