I know what you mean, I wish there were some in my area too.

 

Yes, this is why experts say a turbo's power delivery is peaky and a SC is linear! Plus every stock SRT-4 that I have seen running at the track are going about 14.1! The last time I checked that's faster then 100% of any stock SS/SC on this forum!

 

I have both, the Cobalt SS is slower then a SRT in stock form. I am at a high altitude and
maybe this hurts a blower engine worse then a turbo, but whatever the reason, the
Cobalt SS is slower then a stock SRT.

 

Here's a side-by-side test from Motortrend...Cobalt was a little quicker out of the hole (linear delivery - no lag), but the SRT caught it on the top end, passing it right around the 1/4 mile mark. (both ran 14.4, but the SRT had a 1.5 mph higher trap speed)

Many people don't like "magazine racing", so to say, but when 2 cars are compared head to head at the same time, and same conditions, I think a magazine is a great source of info.

 

Be careful what you ask for.......


Bobby-o!

 

When our 2004 Eblue was SRT was stock it was cutting 2.0 - 2.1 60fts with street tires and 1.8's with slicks. Anybody that would say a SRT has lag in 1st gear hasn't a clue about these cars, probably has never owned one, let alone launched one.

I can assure you that lag isn't what hinders a SRT in 1st gear.

 

^^ oooo thats good lol

 

Sorry, I don't know much about them. Just an assumption based on the numbers. What exactly is it then? I'm curious, because 2.0 is a great 60ft time, epecially with stock tires. Could potential turbo lag actually help get off-the-line traction where the Cobalt's instant boost causes the tires to break loose prematurely?

 

Turbo lag isnt a concern in 1st gear. Lower tire pressure and a 3500 rpm or greater launch, the SRT is into its powerband...

As far as the instant boost on a Cobalt, on my stock 2006 SS, that 'instant boost' equates to no power quite honestly, now I hope my opinions change as I upgrade to the point where we can get 17+ psi out of the blower, but I find stock this car is just down on power up here.

It is far and away easier to break the tires loose on a stock SRT then a Cobalt.

I have owned 3 stock SRTs at one time, now the Cobalt.

 

that is the worst article ever.

cobalt quarter mile time: 14.4 at 99.3 mph
cobalt 0-100: 15.4

neon quarter mile time: 14.4 at 100.8
nein 0-100: 13.8

this makes no sense. it takes the cobaltan entire second to gain .7 mph? and the neon runs over 100 in the quarter at 14.4 but it only takes 13.8 s to get to 100?

 

Perhaps it is the gearing itself, then...I dunno. Or perhaps they had traction issues and couldn't get it to hook right.

 

The 1 second gap for that .7 is because there is a 3-4 shift there. And since the Neon take 14.4 seconds to get to 100.8, naturally it will hit 100 a little sooner...

 

It will not take a SRT 6 tenths of a second to pick up .8 mph, this simply proves the fallacy of this article and the fallacy of putting stock into the magazines as a whole....

 

Defenetly true. The article is weird. I see a lot of articles putting the SS/SC and Redline at 14.9 stock. Then I see the SRT-4 at 19.9 stock. The best stock run in an SRT-4is 13.6, but that has happened a few times, what is the best time for a stock Balt?

 

Yeah lol, 1st gear is so short in the SRT4. Thats what people say is a con in the car when daily driving. When you are decelerating and droping into a gear, you can only shift into 1st when you are at a damn near stop.

 

I agree that it shouldn't take long to get from 100 to 100.8. I don't *think* there's a shift there on the SRT. That would mean a 6500 rpm shift...I didn't think they revved that high. Not stock, anyway. But still, all the other info seems accurate to me. I see no reason not to put and stock in it. The SRT, despite being slower out of the hole for some reason, still caught the SS/SC at the end. I don't know the weather / track conditions, but we all know both cars have ran faster than 14.4 stock. Obviously the SRT has more people that have done it.

I know putting stock in the June article of a Vette versus, say the December article of a GT500 is not close to an even comparison, but when they run head to head tests, the numbers, if not accurate, generally share the the same margin of error between cars. That's all I'm trying to say.

So how long until your Cobalt is in the 11s?

 

I don't know of anyone that's broken into the 13s stock with a SS/SC...close, but not quite.

 

I just want a 110mph trap 1st, then worry about 11's later...
a 110+mph trap will be very diffulcult up here....

As with the SRT world, I am going to have to make more power up here then somebody at a lower elevation to trap that high...

 

I know the guy here that hit 110 in his traps had a 2.5in pulley, among other things, but I thought that was really pushing the limits of the blower. (I read somewhere that a 2.8 or 2.7 redlined the blower at 7k rpm) Are you plannnig a swap for something different?

 

What kind of tuning did he have for the 2.5?

 

It was Fast06SS (or FastSS06...I get them confused). Anyway, he's an HP tuners wizard and did it himself, I believe.

Edit - from another thread.

So it sounds like anything below 2.7" can be potentially dangerous to the SC, but then it's running over the SC redline for such short periods of time that I'm not sure it really matters. I'm still learning here.

 

hhmm...well my friend 06black is wantin to do a custom HP tune to my car...only thing tearing me from doing it is the fact that i wont have him and his tuner there in AZ in 2 weeks when i move. So it's really comming down to either the stage 1 or his custom tune + my 2.9 which is goin on this week, then i find someone down there with his knowledge on HP tuning incase i need help.

 

Both cars are fast. Maybe the stock SS/SC can beat a stock SRT-4. Maybe the other way around. I got two friends over here that have SS/SCs and I love the looks of them. My SRT-4 is my first Force Induction car so I am learning all about tuning and all on it. Hopeing to learn more about your guys cars too so I can help them out.

Anyway, the reason I was posting is one of the biggest problems I have with my car is traction in 1st and 2nd when launching at the track. I get none. I will spin my tires from 1st all the way through the beginning of 3rd. Then I finally get traction and I am off. With the stock turbo there is basically no turbo lag. The small stock turbo spools up instantly. So we have all that power immediately to the wheels. If we upgrade to a big turbo then that might be when we get some lag. I am still running stock tires/rims (deflated to 25psi at the track). Stock turbo, Stage 1 PCM, 75psi FPR, W/I, AGP Wastegate, MBC, boosting about 18 psi, MAP clamp (I think it is like your MAF clamp, something like that). I haven't been able to run the SS/SCs yet but want to to see how I match up. Either way I think they are great cars. It would have been a very difficult decision to make if the SS/SC was out at the same time I got my SRT-4.

Anyway good luck with your cars. Hopefully I get to hang with and race some of you guys when I get back to the states.

MT, show these people some of those damn good pictures like you do over at .com

 

Lemme tell you first hand, Dtec/FCBC is MONEY!
The boost/gear option is so freakin sweet. It's like total computer control over boost again. Now to figure out if i should change wastegates to one with a weaker spring so i can get back full traction in first. (still boosts like 13-14 in 1st with AGP WGA)
