. But to the best of my knowledge there hasn't been one done sucessfully for a turbo.

nice...tuning is not bad and you can tune via 2 bar that should be fine just need to make sure you ahve the right size injectors for the application :)

ok i got a few questions
#1 since all this is done in Colorado, how will this be adjusted for cars located in lower elevations? in my head im thinking the elevations will mess with he a/f ratio but i could be wrong with that
#2 havnt 1 or 2 cobalts with this kit blown up already?

SoCal, you need to give Bill Hahn at Hahn Racecraft a call and tell him that their Solstice with the 2.4 LE5 and E67 ECM turbo (same as the HHR) tuned with HP Tuners alone will not work, let alone turn 12 sec. quarter mile times! 
While you're talking to him, please also inform him that the EcoTec "likes" hot intake air temps and backpressure in the exhaust to make power, too!
If he can get off the floor from laughing, please let us know what his response is.

Once again JoeR; you are showing your ignorance. The HHR does not use the same ECU as the Solstice - it is coded differently. Why not spend some time on the HP Tuners forums yourself and find out just how many problems people with STREET LEGAL HHR'S are having getting their cars tuned. Then get back to us with YOUR findings!
Better yet; - find us a few turbo HHR's so we can talk to the owners...

I guess that a MSME degree with post grad courses in thermodynamics, etc. makes me ignorant..... 
From your past posts, it is obvious that I've forgotten much more that you know.
The E67 ECM used on the 2.4 HHR is used on many other later GM engines, a total of 36 at last count, including inlines, V6s, V8s, ect.
When you talk about HP Tuners, why don't you email the owner, Keith Prociuk, who can vouch that mine was the very 1st HHR tuned with HP Tuners a few months ago after working on beta tests with them. I wrote the 1st configuration file to scan the HHR E67 ECM parameters soon to be incorporated into standard programming, which are very different than past ECMs in many aspects, the 1st configuration for the NGK wideband that is already incorporated into the setup files and have been working on further beta tests related to the E67 ECM, the exact one used in the Solstice. The only differences between applications are minor programmed tune differences and they are very minor. The same applies to the Cobalt 2.4, Saturn 2.4, Pontiac G5 & G6.
On the stock HHR 2.4, just the various parameters that control PE (air fuel enrichment under load), when dialed in, will result in 12 / 14 HP alone. The CGS intake will result in about a 4 HP loss. Unlike you, I've got dyno charts.
As for the HHRs on HP Tuners, you won't find much there. Unfortunately too many have believed that a hot air intake and a restrictive muffler are all that can improve the HHR for power. Wonder why?

SoCal Says: Read my post above - I said it was CODED differently. Which you verify in this next section:
...I wrote the 1st configuration file to scan the HHR E67 ECM parameters soon to be incorporated into standard programming, which are very different than past ECMs in many aspects,
SoCal Says: Exactly what I said above.

Load of crap. You need to re-dyno because you got a bogus run. We dyno'd ALL the intakes 3-times, then averaged the results. I dod not do the dyno-ing; it was done by the owner of West Coast Vipers - who happens to dyno 1000+ hp Vipers all day - but I guess he doesn't know how to dyno (hood up).

The main TOPIC of this thread is Turbo's on 2.4L HHR's - and even STS has failed to bring a kit to market. Eventually it will happen, but to date, there are no turbo kits available. And if you check with HP Tuners - you'll see that they do not support 2-bar, and aspirated Ecotecs are currenlty out of the question.
BTW: Grow up. I'm done responding to you.

DAMN!
ok back on track...all i can say is AD has a kit for the HHR as for production...it is a matter of getting a few kits out there and getting the word out just like any other kit and mass producing them...why mass produce when no one will buy them so they are sold as orders are being placed up to a certain demand.
