Hahn '08 Cobalt SS Turbo 13.2 @ 104

[happy and angry]

I knew this thread was going to have a newly registered name posting a +1 show up in it somewhere.

If you've ever driven or ridden in a cobalt, it's an econobox that they threw a more powerful engine into. Still ugly and uncomfortable, IMO.

So what? Is this a thread about performance numbers or a thread about how the car still doesn't measure up on some arbitrary scale so you can feel better about your car? Here, let me help you out:

- "We're a hatch, I can haul a big screen, SS/TC FTL!"
- "UUUUUUUUUUUGLY FTL!!!"
- "GM build quality FTL!!!1!!!!oneone!!1!"

There, now that that's over with can we please focus on the damn numbers of the car like this thread is about?

Besides, a tune and upping boost (what he did) can get our cars going like that no problem

It has already been mentioned that upping boost does not automatically mean it's putting out more power than we are, as not all turbos are created equal. A catback and a reflash putting up low 13s and traping 105 is impressive. That's maybe $1500 of work on the car.

Little econo-boxes putting up good numbers and getting good tuning done on them is a good thing for all of us. It just serves to get more people interested in turbo 4-bangers and makes the after market for us grow.

Man, I hope that cobalt ss doesn't run into an ms3 with a couple bolt-ons ....LOOKOUT!

[Hyun]

hate to break it to you but both ms3 and cobalt is based on econobox. If you bought ms3 because you thought it was best bargain for performance.. your year and a half too late.

If your insecure about your car and what not, go buy evo and be done with it. You will be set for next 4-5 years.

 

[nvmsp]

oh no something is faster then my ms3.(poke)

You still don't know s*** about 1/4 miles, do you.

Chevrolet lists the curb weight as 2700 or so. Add a driver and a tank of gas, say 3000 pounds, take a guess at the WHP, around 260, you get an estimated run of 13.2 and a trap of 102.

Or go here:

You will see the 13.3 and 13.2 runs ranging in trap times from 100 - 110. 105 sounds about right to me.

 

[tsunami]

wow there is some decent discussion here and then there is some other bulls***... lets keep the bs to a minimum and continue to have a discussion so a cobalt ss put up some good numbers as most of you said congrats to chevy and sport compacts as a whole... stop whining cause now you feel that your car is threatened... who gives a rats ass? if you enjoy your car then enjoy it... if not well that sucks trade it in for an sti or evo or something and be happy again...

 

[controlo]

very nice...guys you need to remember that 22 psi on 1 turbo is not the same as 22 psi on another. You need to compare compressor maps to get a better idea of how the turbo is doing and making power...one thing does anyone know what tuning software they are using, because i thought the ss/tc's ecu would pull power at redline to stock hp/tq #'s...?

yeah, that's a good point. does anybody know what kind of boost they run stock? there's no doubt that this is a good time. i'm sure there are a lot of new SS owners that are stoked right now.

 

[shucky]

Yeah guys, this wasn't a thread about which car is "better." Or "just wait till a MS3 has mods.." I'm a major car nut and get excited about this stuff and since its a DI platform I'm curious and looking forward to see what Hahn's approach will be with extracting some big horsepower from it. I've never had a superiority complex regardless of what I drove, folks like that give the sport a bad rep, especially on the street. If I see a nasty quick SRT4 I give props, but it could be a Cobalt, or whatever. I'm not a hater of other platforms at all, its all for good fun. Keep it on topic please. The new 'Balt looks like a great platform for all around performance and some nasty power. Again, its not for everyone, not even me, but I think its badass with only 2 mods.

The car has a reflash using the BSR PPC tuner (which is like the Cobb AP). With the reflash it dyno'd 289 whp. I dont know where 22 psi came from but nowhere is psi mentioned, nor is it quoted on Hahn's site. For a reflash and catback that is DAMN impressive. Their plan is high 11's on street radials. Although I'm not a fan of the car itself, my MS3 is more practical for me, it is pretty badass. Highest mph of that night was 105. The launch control is greatly helping with lower e.t.'s. 60' ft on the 13.2 run was 2.0 on stock radials. Remember, having a pioneer in turbocharging like Bill Hahn himself taking on a new DI platform is exciting for everyone. Products and technology developed on this platform will only help anyone running a DI vehicle.

cobaltss.net forum, Hahn posted it himself..

I can't wait to see if their cars run into some of the DI quirks we are seing on ours so far. I wanna know if our issues are screwy mazda engineering, or if chevy hits some of the snags we've seen so far ie fuel pump, turbo seals, etc...

 

[Shane5425]

correct me if i am wrong, but dont they have the same turbocharger we use, the ko4

 

[Super Unique]

could possibly be, I am not sure re: same turbo.

One way to look at this is think like a car design engineer, the turbo we have was chosen primarily based on package size and volume pricing. They determined the amount of boost/cfm they needed for the application, then sough an early spool up, along with small dimensions to fit easier in the engine compartment. These factors alone could lead chevy engineers to precisely the same turbo as ours. If you have a high volume product the price can come down, so with chevy and mazda using it the economies of scale increase.

Notice this run is done with launch control.... Hmmmm, if only the mazda could harness it's power in 1-2.. Oh the possibilities!! Impressive none the less, props to chevy.

 

[shucky]

Thanks Shane for the link. Honestly, I could care less if its 21-23 psi. Its corked up to hell with everything stock except a cat back. I'm still impressed. And from reading the cobss forums, Hahn said his quickest runs were made w/out using the factory launch control. He said stock boost is 15'ish, and at that power level its "about" 10hp for every 1psi.

The turbo on those cars may be of K04 variety, but they are twin scroll units, thus not same as our K04-022.

 

[slo03.5msp]

Wow! It can go in a straight line! That's cool. Okay now someone put up a video of it against a speed3 on a road course.

it apparently turns better too. Sad?

 

[montrealms3]

All this gets me excited . . . I am happy with my car but I am also stoked that the cobalt is now quick as well. This means Mazda and others will have to step up if they want to keep their title's atop the sport compact world, which means better things for us consumers . . .

Congrats Chevy . . . now I gotta go get some go fast parts for my car . . .

that's some good info. these cobalts seem almost identical as far as stock horsepower/specs go. i wonder what's going to happen when he puts a cold air on it. 10s? lolz.

WOT BOX baby (gossip) Because it's on another forum, simply add "www." to the begining and ".html" to the end of the link below. Not only launch control, but also no lift shifting
