Its amazing how Chevy just catches up to the horsepower that a V10 is making with a V8 and good fuel economy.

Haha. Of course it's better than all the other domestics. Besides the S7 that is...

But i never pawned my car off as being greater than anything, so I don't really understand what you're trying to get at...

I heard somewhere, I think it was from -Jayson- That the 2.0 ecotec has no break in period, So wromping on it shouldn't hurt it a bit.

[-Jayson-]

no any new engine has a break in period, thats a given. What i said, is this. A rumor was going around that the car limited the RPMS/PSI/HP for like the first 1,000 miles. That is actually not true at all, it was something the dealers started saying because people test driving them said they felt slugish.

I like the Cobalt SS S/C, but the first thing i would do if i got one would be to sell that supercharger and slap on a turbo. I think Gm really hurt the potential of that car by putting a supercharger on it thats designed for up to a 4.0 V6 engine. That charger has got to be taken alot of HP away from the engine. An eaton M62 on a 2.0L engine? Come on GM get your head straight. That engine screams to be turboed, if it makes 205HP with 12 PSI on an oversized supercharger, just imagine what it could do with a turbo.

Sounds like a great ride, but once you get the mod bug and get the smaller pulley/bigger injectors, your fuel economy is going to go to shit.

If this is your commuter, better take it easy with the mods, it might start to get annoying to drive a race car to work....

Then again, I wouldn't mind....

Ahh, I missunderstood you then.

That could very well be...but, the car puts down around 200-205 to the wheels stock, which means something like 225-230 to the crank. GM has them underrated a bit. And they are a little sluggish untill broken in a bit. It's got just under 1000 miles now and it feels much more lively. As a matter of fact, I destroyed a new Acura RSX type S lastnight from a 1st gear roll while I was in a 2 car length deficit at the start, and I had 3 passengers as opposed to the RSX's 2 passengers. The driver of the car who is a friend of a friend went with me for a little ride in my car after we did our little run. He confessed to me that it pulled much harder than his throughout the entire power band. And my car cost me about 3 g's less than him

You can all put this thing down all you want. But Chevy did a great job on these cars...they are no joke.
As for my modding...I'm going to stop at around 300-320 BHP. Once I have that I'll be satisfied.

I'm not stating that this car is in any way better than any other cars out there. All I have to say is that I love it as a daily driver and that Chevy hit the nail on the head with this car. You'd have to drive one to know why.


Oh, Jason...you'd go ahead and void the factory warrenty on a brand new car by spending 4500+ dollars putting a turbo on it thinking that will solve it's problems? Common man, I know you're not that stupid.

[-Jayson-]

yes i would, i did it with my cavalier. I voided the warranty on my 2300 dollar supercharger and the other warranty on the car. Its not stupid, i just enjoy trying to make my car as fast as possible. And no GM did not under rate those cars, lets think this over for just a minute.

Who is more qualified to tell you the HP rating of your engine? A guy who works at a dyno shop making an hourly wage and has a GED? Or a GM engineer paid hundreds of thousands of dollars a year with prolly a master in automotive engineering? Yeah i think GM is right. DYNO numbers can easily be manipulated. And its also a fact that insurance companies do not rate a car on its HP rating from the factory. Sorry for those who think it does.

Nice kill on the RSX i believe you beat it pretty bad. Considering you have a very flat power curve as opposed to the extreme HP spike that RSX has. Also last 2 times ive been at the track ive seen 2 different Saturn Ion Redlines running, neither one of them could touch the 14's.

Dont get me wrong, i love the Cobalt SS and what GM is doing with it, its about time they made a good fun sports coupe. Im jsut a realist, im not gonna stare at all the glit and glammer and ignore the obvious flaws. I love the 2.0 Ecotec engine, who wouldnt love it? When they come out with the Cobalt SS with the 178HP 2.4L Ecotec with VVT, i might actually buy that. I think that car could easily destroy a SS S/C with a good NA job.

Nice car man, have fun with it. If you dont like someone elses opinion or dont agree with it, just ignore it or accept that not everyone feels the same way you do.

I've recently found out that Chevy has in fact NOT underated the Cobalt SS. They did something even sneakier. They posted the 205 bhp @ 5800 rpm, which is correct. The thing is, the Cobalt gets it's max power after 6500 rpm. Guys are dynoing these things bone stock @ 215-225 whp when doing dyno passes up to 6800 rpm(and have the dyno sheets to prove it). When you calculate drive train loss that's close to 250 bhp. I'm assuming this is Chevy's ace in the hole with the Cobalt SS.
I've also heard that many ppl are taking their stock cars into the low 14's as opposed to high 14's. I've yet to see this but will find out for myself in a week or 2 as I've figured out how to launch with my open front end.

it is kinda hard to cheat your way with a boosted car to get it read a higher from the factory when its bone stock.

i know that performance parts companies likes to exagerate their claims by dynoing a hot or worn stock car to get a lower base line number, then get a fresh and cool car with the parts installed to get exagerated claim numbers.

but this is the exact opposite, unless chevy is putting their cobalt SS's on the dyno in 90% humidity at a 105 degree dyno room to get their engine dyned, i don't see how the numbers would read 20 whp less then what everyone else is getting. people do underate cars you know, the LS1 is a perfect example, its trap speed to power to weight ratio shows that the engine does not make 315 crank hp but more like 315 whp.


why do companies underate cars? no clue.

edit:
and yes bulldog is right, i forgot that if you look at the powercurve for the supercharged ECOTEC's they don't stop making power. the power curve is a straight 45 degrees all the way to redline, it never drops. if the engine can rev to 7000 rpm it would probrably still be making power. so them rating the engine @ 5800 rpm is just weird.

Just Chevy's honest way of cheating the system is all

what system are they cheating?

[BullDog71ss]

What reason do auto companies have to underate their vehicles other than for insurance reasons?

none, like i said before, insurance companies dont rate cars on there HP rating. Thats why it seems dumb that GM would under rate the car.
