Well the Cobalt ss/sc are having their front ?axels? brake with stage 3 set ups so there pushing like 300hp+ easliy but there also drving it hard at the track it doesn't seem to be happening on everday drivers but on the dragsters. As far as the clucth it should hold with the kit stock but past that i would upgrade but you shouldn't have n e problems. The brakes well no one should be drving 90+ then slamming on the brakes n e ways.....

 

Ya I brought it back from from the dead, but was on Hahn's website says HHR turbo system is in development. I don't if it has been that way or when it changed but hopefully it will be released soon. Xmas is around the corner

 

so is tax money season

 

sure, you don't have to have an intercooler up until about 6/7 psi when your engine starts knocking...

getting an intercooler will help keep everything safe - even if you're not looking to build a huge monster.



hahn has been in this game a long time. they make some big turbo kits for the srt4s, subbies, etc... and they did the first add on turbo kit for a ptcruiser and they are still running fine 5 years later. you do need to have at least a working knowledge of fuel systems and basic tuning to keep things safe but it's nothing you can't handle with asking a few questions and not being stupid...

go for it when it's out.

 

Still doubtful about this, with such high compression in the 2.4L I would be worried about blown gaskets. Hahn would probably address this but, I wouldnt add boost to such a high compression motor, just not a good idea.

 

Seems to me that if this was so easy to do, it would be done by now. It's not like they just started working on this; it's been in developement for at least a year.

 

id rather a company take their time choosing the right turbo, plumbing, and tuning components instead of just throwing something together...

throwing a turbo kit together is what blows gaskets and heads... not r&d.

 

I'd say after two years of R&D we don't have to worry about them "throwing it together".

 

Nope quote from the cobalt turbo kit:
After 2 years of extensive engineering and testing, Hahn RaceCraft has achieved a turbo system with a fuel management system that works exceptionally well. Coupled with an ECM re-flash (included) and a TCM re-flash (for A/T vehicle) is Hahn RaceCraft's exclusive field-adjustable, boost-proportional fueling system. Hahn has conquered the difficult 2.4L ECOTEC tuning with the development of Hahn RaceCraft's BoostFueler. Conventional tuning procedures do not work well on the 2.4L ECOTEC motor. The Hahn RaceCraft BoostFueler makes performance tuning an easy reality. Your vehicle will maintain excellent drivability and civility. The beauty of
this system is that it works for both manual and automatic transmission vehicles and creates more horsepower per pound of boost compared to the 2.0L supercharged Cobalt SS. The horsepower gain is impressive! Create a
vehicle with super consistent bracket racing potential ..today!

So that means any day now it will come out

 

So why is everyone jumping on me for merely pointing out that this has been R&D'ed for sometime and there is still nothing on the market, Neither of you really stated anything that changes what I said.

I said it wasn't easy and that no one could accused them of throwing it together. What's was wrong with saying that. If it's not in production, it's not in production. Pretty simple. Just becuase it's in development and they SAY it coming soon, does NOT mean that it is.

I hope it is. Since I won't be getting an SS, this will be my best chance at anything close to a high performance HHR.
