what is the top speed/govenor set at in the cobalt ss 2.4l's?

 

i couldnt tell u for sure, but im guessing around 125-130mph... thats a complete guess so im not sure

 

i think the tires are rated to 126 and thats what i saw one time, then 130 but could have been the speedo off or the downhill

 

133 according to my handheld gps

 

i agree i cant seem to crack the 135 mark..always stops around 133 or so.
( i try once a week...sunday mornings around 5am on I85N)

edit: a tires speed rating indicates the speed it can safely maintain and not shreed or explode...if i took a 90mph rating tire and took it to 130 and backed off id be safe no prob.....but if i decided to make a run for florida from north carolina at 130 no way would i even make it out of north carolina without blowing a tire

 

Yeah about 130. But thats plenty fast enough!

 

Someone in a Cobalt SS just said he screwed up his speedo doin like 160 5 times in a row...... Thats Plenty fast!

 

The guy who drove my car from PA to have it delivered in time for my graduatin told my parents he took it 147 before he backed off. Ill kill him if i ever get ahold of him.

 

Then again, I have a fairly quick SS 2.4L. I took my friends SS/SC off the line and all the way through 2nd gear. He's stock except for a big ass muffler. Once he hits third though, its bye bye watchin his ass! Just need a better exhaust and I'll be outrunning him.

 

Damn Id be pisssseedd!!! I hardly let people drive my car.

 

I was pissed. They didnt tell me when I first got the car because they knew I'd hurt him. It was a graduation gift to say the least. A replacement for trading in my wrangler and civic.

 

Only if you have spray, and quite a bit of spray at that.

 

HPTuners says the first limiter is at 129 and the second is at 129 as well. Although there is a value of 140 set for the limit and resume in the speed limiter 2. Its confusing. I'll try and take a pic and post it. Something interesting I see though, the source can be calibrated or use GMLAN as a source.....whatever that means...

 

Nice Doc, that would be very cool! Goin to this sundays meet?

 

I've had mine up to like 115 or 120 but I think I read somewhere that the limiter is about 130. I've never had the need to go that fast so I couldn't be for sure.

 

well we can do at least 120 \/ \/

 

I dont know why but I can ONLY reach 121. It is REALLY pissing me the F off. Any help??? Shifting to 5th is practically useless too, I start to lose speed when that happens.

 

maybe it's all the drag from that SC wing???

 

This was done before the SC wing was put on.

 

My speedo only goes up to 120 and I have passed it a few times. So I know atleast 120.

 

but I thought the base models limiter was set to 105? i think they messed with cars from the factory for the hell of it.

 

what gas are you running in your car? i have gotten mine to 128 in 4th gear then went into 5th and i stoped at about 130ish a little over. the 2.4 goes thats for sure. rev up that motor and its happy.

 

No one here is going to believe me but i have hit 140 twice. 4th gear tops out when i hit 140.

 

I've yet to have a straight place to do it on.
