SS/TC Upgrades from Hahn RaceCraft
It's official...we pick up our SS/TC today!
We are getting her from Lattof Chevy in Arlington Heights, Illinois. Those of you familiar with Crate Engine Depot, another fine vendor at this site, will recognize Lattof as CED's home base. We are pleased to work with such a faithful supporter of Cobalts in general and Cobaltss.net in particular!
As many of you know, Hahn RaceCraft has led the way with turbocharged Ecotecs since their emergence in the US with the 2002 Cavalier and Sunfire. Along the way, we've raised the bar repeatedly for Ecotec Turbo performance, while introducing hundreds of Ecotec owners to the sublime advantages of Turbocharged Power. Our very first Eco-effort won the prestigious GM Design Award at SEMA, an impressive 12-second, stock engine EcoCav show car that ran 12's with our bolt-on TurboSystem. We haven't looked back since, with more records and firsts than all others combined.
We're proud to bring our 20 years of GM FWD Turbo Performance to bear on this exciting new application of the LNF Turbo! We've had a great time with this engine so far in Solstice/Sky and HHR, and now it's the Cobalt's turn.
Products we'll offer include:
The goal? High 11's on radials, stock engine, just like we did with our SRT-4. This is going to be fun!

- PPC Tuner
- Intercooler Upgrade
- Piping Upgrades
- S20G Turbo Upgrade
The goal? High 11's on radials, stock engine, just like we did with our SRT-4. This is going to be fun!

Nice.. I sent your company an e-mail today wondering when you were going to start supporting the balt since you offer tunes, etc for the other 2.0L LNF vehicles already.
Yeah Haw...

I agree. The K04 is capable of pushing enough air to get the tq up in the low/mid 300's at the wheels. Hopefully the direct injection can be tuned effectively.
It appears (and I say this after only reading a couple of dynos) that the tq peak is being managed by the ECU. So maybe bolt ons will have a minimal effect without proper tuning. I could be way off base here.
Looking forward to your work Bill

Im looking forward to the turbo upgrade! The stock turbo is WAY too undersized - it runs out of air around 4.5k rpm...
I just got my car dyno'd this weekend and the speed shop was pushing hard to let them start messing around with trying to tune it.. uh... no.
They told me this was the first DI car they had dyno'd and were going to use my dyno charts as baselines to compare to other cars (AFR wise)

What a terrifying idea, the possibility of a privately owned Cobalt with a Hahn turbo system under the hood. This is terrible, Cobalts might actually become fast.

Edit. It was a statement and a fact, this is not my thread, so do not argue - send a message to me if you have a must to.
Have you not read? anything? i never once said removing a muffler makes you fast & have crazy power.
It is barley a 5hp gain and thats only above 4k from what i seen on dyno testing.
You should be banned for trying to ruin someone elses thread ' a paying vender none the less' like you did mine '

This isnt correct. For a 2.0L motor, the K04 is adequately sized. It's efficiency range is actually quite nice and could easily handle 20psi. Like I said, mid 350wtq is achievable on the K04.

Drove it home last night, and the wife's got it today. She'll be back soon, then I'll post some pics. I may be partial, but it's the best looking Cobalt I've ever seen!

Im not convinced of that until I see it - the dyno runs just show a nice torque level that steadily drops down from its peak numbers.. Maybe this engine just needs the correct supporting mods, but it just feels asthmatic at higher RPMs.. Low to mid its GREAT. Maybe thats the way GM programmed the computer? Who knows until some serious tuning gets started.

Essentially forever...we've run these transmissions up to ludicrous power with no issues in other applications. It all comes down to not abusing it needlessly:
Slicks or Street Tires...What's best for driveline durability?
