Hey Guys and Gals, I'm new to the the forum and wanted to say, Whas' up. I just bought the 2006 cobalt S/C SS and have to say its not what I expected. There is not as much power as I was hoping, but it's a nice car to drive. The governor kicks in at 130mph, which is disappointing. I was hoping to achieve 155mph. So, if anyone can direct me to the upgraded computer chips I would be very appreciative. Thank you much. I'm looking forward to searching your forums. Alot of great information on here.

 

The Cobalt SS-SC has no governor! You must have bought a Cobalt SS (2.4L, 171 HP) not the Cobalt SS Supercharged (2.0L, 205HP)!!!! The Cobalt SS shuts down at 130MPH due to it's all-season, H speed-rated rubber. If you were driving a Cobalt SS-SC, you'd have likely gotten to almost 150MPH!!!

Double check what you bought, cause I think you are confused about what you bought!

 

Im pretty sure all the cobalts have governers. regardless of model. So far i havent heard of any chips yet to rid us of that speed restricter.

 

The SS S/C is drag limited, there is no mechanical speed limiter other than it's own aerodynamics.

 

NO!!! All Cobalt models are electronically limited, excet for the Cobalt SS-SC. It has tires that are W speed rated, so they are safe to operate at speeds up to 169 MPH. The SS model wears H speed rated tires, and is goverened to 130 MPH because the tires will break up above that speed. The models under the SS 2.4L are eleectronically limited at a lower speed (about 110 MPH I think).

Manufacturers have to limit speed on tires if the car is capable of going faster than the tires are made to! Otherwise your tires could explode, and you would likely be injured or possibly dead! DO NOT GO FASTER THAN 130MPH WITH THE STOCK 2.4L SS H-RATED TIRES BY REMOVING THE GOVERNOR, AS YOU WILL CRASH!!!!

Thay guy either got suckered in to buying a 2.4L SS (hopefully not at a SS-SC price), or he was confused about the Cobalt models and bought the wrong one.

There are people on this site that have driven their stock Cobalt SS Supercharged coupes well past 145 MPH!!!!

See this thread: https://www.cobaltss.net/forums/show...ight=Top+Speed

 

first of all, congrats on the car!

I would have to agree with the others.. the Cobalt SS SuperCharged doesn't have a governor...
if the car has a governor then it must be the Cobalt SS 2.4vvt not the S/C...
(hopefully it's not an LS or a SS with badges and wing slapped on it )

If you could provide us with pictures of the car and engine bay it would explain things

so far I love the power of my 2006 SS S/C , I havent had it over 100mph yet though.. and probably wont take it up to high speeds too many times.. the acceleration is excellent though it certainly gets up to speed in a hurry

 

Yeah, sexy, I'm guessing you bought the 2.4 . . . nobody else has had this trouble! I've had my Redline (I'm an Ion guy, not a Cobalt guy, but it's cool) up to 130 mph and it still had more than enough left . . . hope you didn't PAY for an SS S/C and get the N/A model, because that would be a shame . . .

 

Actually an H rated tire could run up to 150mph but it wouldn't be able to substain those speeds for a long period of time.

Unless you are driving on a race track or using S rated tires I doubt anyone will be crashing due to exceeding the speed rating in short bursts.

In the video link I posted a while back a Silverado runs 10's @ 120+ on stock Firestone Wilderness tires.

As for Sexy S/C he either bought a SS N/A or he traded his Z06 in for it.

 

not all cars made have speed gov's , most GM made vehicles do though


and gotta love people ignorance about tires , ive been over 150mph on SR or lower tires for long distances , and never had 1 come apart


tires will come apart for several reason , the biggest cause of tire failuer is low pressure , next is road debris


yes the speed rated tires are safer at high speeds , due to being made from different rubber compounds , and the way the inner carcus is made


GM and several other companies have done the speed govs for alot of reasons , safety is 1 of the biggest reason , but its limited to just that reason , brakes , not making 1 car in the line-up faster than another example the corvette and the caddie counter part , the caddie is goveren lower , to set certian customers to either the caddie model , or move them to the vette


that sucks GM limited the 2.4 ss to 130 , cause i hate the wing on it , and i hate the 18" wheels

maybe ill wait for the sky redline , cause im not gonna get the ion redline , i hate the center cluster , LOL

and the center cluster is the only reason i hate the ion's


oh well cant win them all

 

The sky redline may be my next car after the cobalt

 

well i have a 2005 ss/sc and i have had it at 120in 4th gear at only 5700rpm and still had all of 5th gear to go... so i know the car goes faster than a buck 30

 

Congrats on the car! Where are u in WA?

 

I will assure you that the car is a 2006 SS/SC. I also assure you the car in it's current form (stock) will not reach 150 mph!! Maybe down hill with a strong tail wind. What I think my Fience was really asking was is there any PCM's released yet to allow a faster top speed, or top end power. I know about the future staged upgrades from GM but they are not out yet.

I will assume since no suggestions for an after market PCM or controler have been mentioned none are avalible. So what is avalible right now? Pullys and a shorty header? Maybe a CAI? Looks like the aftermarket is sleeping on this one. Thanks for your helpfull answers (the few) and to the rest............ get a life.

If your new car is truly a "supercharged Cobalt SS" the only upgrade that you will require to exceed 130 mph is the " ***** " to do it. If your car in its current form will not do this may I suggest that you take it to an authorized GM dealer for warranty work. I am going to go get a life now.

 

Yes, if the car absolutely cannot exceed 130, there is something seriously wrong with the car. It has the gearing to go WELL beyond 130 and as others have said, there is no electronic limit on it. GM claims it is drag limited to 144 but others have had it up in the neighborhood of 150, so only hitting 130 to me says there's something wrong with the car.

 

Agreed.

 

it would be break in new car mode
ease off your car for awhile

 

I didn't think of that. HAHA, I am slow.

 

That is some funny stuff. Is that a GM trade mark? "No more worrys with our cars thanks to BINCM. Yes you can get the new Break In New Car Mode in your new Chevy".

So at what mileage does this "break in new car mode" shut off? The manual says 500 miles for break in right? So at say a 1000 miles the car should be good to go. Believe me both she and I have no problem going faster than 130. I think the "few" people who claimed to have went faster stock were 1. going down hill 2. over exited and exagerated 3. got a good freak. My buddy has a freak car and has always been faster at the 1/4mile than cars with the same mods. So i know it happeneds.

the car could......... just not under it's own (current) power.

I don't know....I'm pretty sure my car is capable of high 130's low 140's haven't went that fast yet (don't have the guts to yet) only like 125 so far. However if I were you and this car is new, i'd keep it easy just until the car gets to like 1500 to 2000 miles.

 

BULLSHIT, AN ss/sc WILL DEFINITLY DO 150, I'VE DONE IT SEVERAL TIMES ALREADY AND I DO 140 TO 145 ALMOST EVERY WEEK, STOCK!!!!!!!
NOT DOWN HILL EITHER.

IF YOU CANT GET TO AT LEAST 145, SOMETHINGS WRONG WITH THE CAR

 

Give it a little while. Get past 2000 miles before you do anything drastic.

 

Like someone else asked, can you post pictures of the car and engine? 130MPH is not the top speed of the SS\SC.

 

Well i got hit 150 with only 700 miles on my car haha!!!

 

1. going down hill
I hit in the neighborhood of 140 on a stretch that was if anything slightly uphill

2. over exited and exagerated
165mph in an ss/sc is exaggeration. 130+ is expected. I know I've seen my speedo needle WELL past 130 at the track on more than one occasion

3. got a good freak. My buddy has a freak car and has always been faster at the 1/4mile than cars with the same mods. So i know it happeneds.

Depends on how much faster in the quarter mile, at that it could be maybe a difference between a couple mph. Being able to reach 144 in a car that's designed to reach 144 doesn't sound like a freak occurance, it sounds like what the car is meant to do. It's definitely got the power to hit 144 and there's still more left in 5th so gearing isn't an issue either. If you're not able to get over 130, I'd be worried. Obviously, it's not a situation that would be suited for calling up the warranty department, but if you've got a car shop you deal with regularly, I'd get another opinion on it there's no reason why the car shouldn't be able to get to 140+
