well looks like its becoming a reality, saturn performance devision is making an lsd option of the 05 red line, thats sweet. i'm lovin it.

 

I just bought an '04.

Hopefully they'll give me a good deal to install an LSD on it.

 

yeah that would be sweet if they give u a deal. maybe incorporate it in to your payment plan.

if you drag, you should definatly do a before and after 1/4 run see your times before and after the lsd install. that would be awsome.

 

i'm hoping that with an LSD, we can get MUCH closer to 13's! considering the 14.5 recently run was with a launch of 1500rpms! if we could launch a little higher, with a 2.0 60' time, i think we'll be seeing at least 14.2

 

I agree. These cars have good factory tires, they just get shredded with an open diff. An LSD will help the hole shot considerably IMHO. As someone said, the trap speeds are high, so once the traction issue is dealt with these cars should really get good numbers.

 

yeah i mentioned traps being high and those mph numbers where good for low 14's 1/4 times. and w/ a lsd i think 14.3 is possible, 14.5 is allready wrx times which is respectable, add that lsd and you'll be hunting srt-4's

 

I don't know about hunting. =) 2003 SRT-4's (minus LSD) were running around 13.9 (with a good driver). The 2004+ have LSD + stage one. I've heard of them running 13.7 or better (again, with a good driver). I do feel, however, a lightly modded Cobalt SS...say, intake, exhaust and perhaps some ECU mods (redline or fuel mapping) would easily drop the SS into SRT-4 territory, or...better.

 

i agree, now if gm makes that option for 270hp than that would be srt-4 hunter. please gm make that a freaken option.

 

As much as I hate to say it, I don't think it will be an option. At least not for the 2005 model. If sales go well, and the general response to the Cobalt SS is favorable in GM's opinion, I wouldn't be surprised to see something similar in the 2006 models. But..one can hope.

 

i believe you are correct sir, or they will offer it as an upgrade that voids warranty late in the '05 my

 

its kinda hard for something from gm to void the warranty, its a gm performance part so they kind of have to keep the warranty.

 

If the lsd you are referring to is limited slip differrential, your times aren't likely to be any better with it, unless you are using tires that have no grip. A set of slicks or drag radials aren't likely to be breaking loose with 200hp, even without lsd.

 

Header is already available, check the redline forums for details.. or my site.
I just don't want to say it's for the SS until I have installed and tested it for fit.

 

SRT4>SS

Stage 2 SRT4's are trapping around 108 in the quarter mile.

Going to take a few major boltons to hit 108 in an SS

 

As I recall, the SEMA SS had 270hp. I'm sure that's more than enough to trap 108, considering the 04+ SRT-4's with LSD and Stage 1 included are rated at 230. And from what I remember, there wasn't anything too major about the modifications.

What do you think it'd take to get an SS into 'SRT territory'?

 

Rated at 230? Stage 1's put down over 230 to the wheels. Stage 2's are putting down 260 horsepower and 290+lbs of torque to the wheels.

The SS is going to need a bigger blower and it's ECU hacked to contend with those numbers.

 

after proper break in, hope that the car gets into the 98-101mph territory stock.our SRT4 got 13.91 stock at 101 mph and a 2.01 60 ft.

the best now with the larger turbo is 12.39@121.41mph. That was with a 2.1 60ft. There is more left in it with LSD and slicks. 11.5x's shouldn't be a problem.

Hopefully the Cobalt SS can duplicate this if i decide to go with one.

 

Would you happen to have any dynos proving that? I'd be interested in seeing some. - I know the SRT-4's were under-rated. The 2003's were rated at 215-220 crank, but were in actuality, putting down 215-220whp. I saw plenty of proof to support that. I'm not saying it's impossible, but you also have to consider the fact that the Ecotec platform is a proven engine. It may take a bit extra to see the same or similar gains as an SRT-4. But if that's the case, it's only due to the fact that Dodge is putting them out with more factory power.

 

our car made 215/246 stock.

with a $150 wastegate actuator our car put out 241/254.

our best dynojet numbers were in the 264-269whp range with the stock turbo and intercooler. we still were able to attain 110.99 traps with this tiny turbo, stage 1, 3" turbo back and intake system. actually now there are a few SRT4's with stock turbos trapping 110-114mph. Hard to beat that.

Hopefully the performance shines on the ecotec 2.0. would have been nice if it were a 2.4L S/C though

 

You may have the SS beat performance wise for stock capabilities (for now, perhaps that'll change later). I never denied that...but, what about quality? I've sat in a few SRT's..driven a couple...and I wasn't very impressed. The seats were also very uncomfortable...and the interiors very plain. What I've seen of the SS interior and such, it looks worlds better.

Anyway, not trying to start a war. I don't deny the obvious performance capabilities of the SRT..but, as this is a Cobalt forum, most members are bound to be a bit bias. Time will tell.

 

Yes, and the 2.0L SC in the Cobalt SS has put down 210hp to the the wheels stock in the ION Redline. SCDyne performance has built a header guaranteeing a 10% increase in wheel hp, bringing the 2.0L SC to 230 to the wheels. This is before working on intake and exhaust. The 2.0L SC also is still building power at redline, and if the ECU can be reflashed to increase redline we should see a great increase in power.

In essence, I believe this was all that was done to produce the 270hp Cobalt at SEMA. I/H/E and reflash to raise the revlimiter. Stock S/C, stock IC, stock internals, bolt-ons only other than the reflash.

And as Silver said, I still believe the SRT-4 is a better straightline performance car as far as we've seen. But the Cobalt has a lot of potential, and IMHO is a more well-rounded and premium small car.

 

things are hard to tell when the real car is not out yet.
I like the SRT4 since i have worked with it and was able to extract 413whp at 24psi with room left in fuel and boost. Our SRT4 sit just out side.

I am here just as you are. we are looking forward to the release of the Cobalt SS.
I actually like the support in the SRT4 seats. Quality isn't as bad as one thinks either, there are somethings i can pick on coming from a Japanese car buying/modifying background. so far we have had:

196 passes down the track
148 dyno pulls
51,000 miles

And thus far on the stock internals, only thing that has broken was our drivers side axle. well it's not broken yet but it's on its way out.

I am here to read and know more about the Cobalt. I am not into 4DR cars. we already have an SRT4 that we have to play with but it's hers. I am looking for a "NEW" car.
I am weighing my options and I keep my eyes open for my next thing to build up.

I am not done with our SRT4 either....

 

that's great, hopefully the 2.0 will be as bullet-proof as the 2.4 in the SRT, should be, but we'll see!

also, the computer seems to limit boost to the 12 or so PSI, when the headers Adam produced were on the dyno, he said the boost pressures stayed the same, which is why the power increases were so great (boost should come down with freed-up exhaust). so with the headers, a 3" exhaust, free flowing muffler and intake work, i bet we start to see some serious numbers on the dyno from these cars. hopefully by opening up that much, we'll really see the potential of the m62 in action, as it is the most efficient version yet.

also, i'm hoping it can keep up with the I/H/E and still put out the 12psi once all that is done, then we'll really know that these cars are detuned from the factory!

 

call me wierd but i like the interior of the srt-4. its simple not wow amazing but simple and simple sells. just like the cavalier, not the best interior but its simple easy to get used to and fairly comfortable, srt-4 seats are comforable.

 

Ugh, I hate the Cavalier/Sunfire interior, and I sell the things! I actually think that the interiors in the 3rd gen j are worse than my 2nd gen. Not that my car is anything to write home about.
