Good news guys. I received a call from Bill Hahn today and they have my SS disassambled getting measurements for a bigger intercooler and intercooler pipeing. He also is going to look at the exhaust. They make the best replacement intercooler for the GXP so I know the one for the SS will be just as good. It will be awhile before he has the parts ready but it will definitly be worth the wait. My GXP runs really strong and it is an automatic so the SS being a 5-speed should be a real blast when he has everything compleated.

You guys are killing me with your new tune! I ordered 2 days ago and sent in the Vin# etc to HRC. I have an 07 Vette with 500HP to the wheels, but that in Vette terms is mild, however the HHR SS #'s are going to be far more fun to play with other peoples rice burners!

It's my specialty, especially when someone asks a question that's already been answered (sometimes repeatedly) without even bothering to read the thread and/or using the forum search feature. It's called spoon-feeding, and it's annoying to many.

just picked up our ss last night and just spent allot of time reading thru this post. has me kinda giddy to think of another 40 or so hp available. and in the tuning community a grand for 50 hp. is a huge gain. im going to spend double that to supercharge my sunfire this winter. for the same 50 hp gain.
my question is engine strength. i know with the 2.2 ecotecs at around the 300 hp mark some of the internals start to fail. how strong are the 2.0 internals. anyone know what the magic number is for things to start going boom? going to build the ss for street and show and want more power but i want it reliable as well as this is the wifes daily driver for now.

good little read. good start. be nice if they did a build book on the 2.0 like the did on the 2.2. its nice knowing how much power each part can handle before it starts to go. a good start to my learning though. the ss purchase was just a quick unplanned buy for us and since were starting with a new more powerful hhr i want to get my hands dirty on it.

We did several hand timed runs at mid 13's and 108 indicated recently. Judging by the well documented times for the Cobalt with the tune, I believe the 13.8 @ 103 is right on for the HHR with the tune. Upgraded intercooler, exhaust, track tires might get it close to the magic 13.
