your governer is just a PCM program,it reads the VSS and it limits the speed of the car to what evers programed in to it, if you had a aftermarket programer that would fix u up

Why would you want to take the govenor off a non-performance car?
Now if it was an SS/SC I could see why. But the LS family-mobile?
That's just asking for trouble. That car wasn't designed for speeds higher than the govenor allows for on public highways.

Actually, the average govener is placed on a car because the stock tires are not rated for the speeds the car can actually reach (which is why the ss and redline don't have one), so saying the car wasn't designed for higher speeds isn't acurate as the car will probably not have any problems going past the govener speed, but rather the tires will.

So what you're saying is that all car engines are designed to go at close-to-redline speeds?
You're right about the tires, but there's more to it than that.

I would hardly call a non-SS/SC Cobalt just a family-mobile. GM is working hard to produce modifications specifically for the 2.2L Ecotec (and the SC is apparently already out) because the engine under our hood is capable of MUCH more than they are currently putting out and they know some of us non SS/SC owners are going to want to modify our cars beyond what most people will do with them. If you leave it as it is stock then sure it's not a high-performance vehicle but it has more than enough potential to make it up there :). If you read the GM tuner guides for the 2.2L it has been tested reliably without a rebuild to somewhere in the range of 300hp (I can't remember if that's just the manifolds or the whole engine so it could be higher) so it is possible...we just need to put the money into it to do it.

As for the governor, it's capped on our cars apparently at 170km/h which no body in their right mind should be doing on roads anyways. Even running 1/4 miles I don't think either the LS or SS/SC (which as far as I'm aware is not governed) are going to reach speeds this high. Depending on what tires you went with you would have to check their rating and figure out what their max speed is before the rubber pulls away and you kill yourself. The governor should be a chip re-program which I wouldn't imagine the dealership would do and as far as I'm aware there is no way for anyone but GM to do this at this time.

There are generally 2 limiters on modern cars. One is for absolute engine speed (RPM) and is sometimes programmed to give different limits based on gear, engine temp, or whatever the engineer wants. The second is a limit on vehicle speed (just like it sounds).

Critical driveshaft speed is a big concern at top end (at least on rear-drive vehicles) and, I believe, it is the biggest concern, after tire rating.

man thank you guys alot for all of the info. you all have been really helpful. i was just at nopi this weekend and that ECKO Cobalt is fast as hell. but the fastest car this weekend from 1-3 was the AEM civic 6.5 at 213 mph, a celica(forgot the team)6.7 at 209mph, and a eclipse(forgot the team also) 6.9 at 199mph. the cobalt tho broke something and we couldn't tell what tho, but that thang snatched off on a supra and was spankin it until something snapped.
