Actually, the GM stock automatic trans is rated to handle much more torque then the manual. And there are very few manuals out there. The engine has forged internals, so like all the others, the pistons are most likely the weak link. But Hahn has run the engine in other cars to over 400 HP.

 

So the 2.2L project was scrapped, and Hahn went to the 2.4?

Was the 2.4L tuned with SCT? or was it still stock tune? If stock, that really was impressive!

 

They say the 2.2 kit will be out soon. message hahn

 

Not scrapped. They have the same problem we all have; no ability to tune the ECM.

 

As soon as this hits the front page for sale my computer and my finger is ready to hit the send button and get my conformation and Tracking number believe that. I will be calling places for the install price or I will just have my boss drive me to work and home for a couple of days and do the install at work. I would like to do the install in one day but Got to wait for the ecm to get back anyway.

 

i dont believe the install would be to complicated....other than the fuel system....i mean think about it....drain the oil.....install turbo/manifold....install intercooler....install piping....install oil lines.....install all necessary fuel components....slap the newly tuned ecm in....and your good to go.....o and put oil back in.....not to complicated really..as long as you have the tools and what not....could this be done on jack stands?...i imagine so i just think itd take a while....

 

halfcent how much can the manual trans hold tq wise do you know? cuz the SS im lookin at is manual.

 

Anyone know the thread for the 2.2 Balt's Hahn turbo kit... or the web addy?

 

No, not SCT, and no, far from a stock tune

I'd like to add that we've proven these manual transmissions capable of holding together even at low 11 second ET's with slicks, and will soon debut a new version of our turbo Sunfire with the manual trans and absolutely sick power. So far, so good on the Getrag manual!

Will the auto also hold 11 second power? Theoretically, as Geoff pointed out, it may be capable of it. It will take time and effort to get it there, but for now, we are pleased as can be that its holding up well to our current onslaught of approx. 300 HP and 300 ft. lb's of torque

 

Can someone answer once and for all WHY the 2.2 ECm has not been hacked or you have the ability to tune it yet. What makes it so difficult?? HP tuners has the 2.0/2.4 and just about every other GM engine unlocked...why not the 2.2?????

Sorry 'Lope still a youngster I got you by 5 years...but I agree, many in their 20s in here.

 

2.4 all the way....finally we are goin up....cant wait till the turbo goes on sale....even tho the BOV is a sleeper i luv the sound of it lol

 

The tuning issue has been answered in many previous threads. The simple answer is economics. The companies that make tuning software like HP Tuners focus their efforts on the most lucrative segments of the market. And the E16a ECM computer in the earlier L61 cars have a very small market share compared to a new Ford Mustang.

Here is the best news I have, but it is old as well. The forthcoming Garrett kit uses software made by SCT. So, SCT does have flash tuning ability for the computer. But until they actually release a product, we still have nothing.

As far as trans numbers go, all I do is qoute published specifications. GM says the Getrag F23 transmission is designed to handle a maximum engine torque of 155 ft/lbs, while the automatic 4t45e is rated at 205 ft/lbs. Now obviously people have put more the 155 pound of torque into the F23 and it has worked just fine. My only point is the automatic is rated by GM to be stronger.

 

Sorry I don't frequent the 2.2 threads-but I am doubting or wondering why the ECMs would differ substantively from the 2.4 or 2.0. I mean there should be some commonality of prgramming to facilitate an easier hack as opposed to a clean sheet o paper type of programming (compared to the 2.4 and 2.0). You'd figure HP would rather be the ONLY guy in town rather than an also ran when it comes time to get into the 2.2 ECM.

 

...but a lot of people are all talk and no action. There's no gaurantee you'll sell the product to enough people to warrant the time and resources spent on developing it... especially when you're talking about a car that's mostly sold as an economy car.

As for the track times, good times. It's very promising. We could see some really nice times out of a turbo 2.4L with a few more psi, some tires, and some more fine tuning.

This is all great news though. I just hope people actually follow through and buy the kit.

 

And there in lies your confusion. All three engines in fact have three completely different computers and operating systems. They are very much different.

 

The LSJ PCM has more in common with the colorado's than the 2.4 or 2.2 cobalts.

 

...x3

the video will be the icing on the cake to have everyone hooked on your turbo system and follow through, best advertisement to have would be a video

 

Haha... it's not my turbo system. I'm just saying "we" as a collective group of 2.4L Cobalt owners.

 

Just out of curiousity..What were the GXP's numbers? Or did I miss it somewhere in this thread?

 

The GXP ran a 13.72. It has a bit more boost than stock and a few more modifications in the reflash.

 

lol...no no i was still reffering to hahns turbo system! basically saying we are all eager to get our hands on the system and a video of it would just close the deal with most of us

 

I think if the ss/sc JUST had stage 2 on it...I would think the 2.4L would win, as I believe the turbo 2.4L has 240hp AND 240tq. WHich I believe is more than a stage 2 ss/sc.

So, if the numbers warranted it, and you guys released a stage 3, or even stage 4 kit, could we be looking at well over 400hp with your kits? It may persuade me to special order a 2.4L SS

 

We know that the motor is capable of over 400 HP, that is for sure. The variable here is what can the transmission take. But you are right, if the numbers and demand warrant a stage 3 and stage 4, I'm sure we will develop one.

 

Can the manual tranny handle more then the auto?

 

They say it will handle 11 second power. How much that is I have no idea
