Cold Air Intake that works!!
Knowing that most of the available intakes for the HHR only add looks, I decided to do a custom designed cold air intake that REALLY works. 
Actually, you can't see the intake. From the throttle body, it turns down, over and back up under the headlight. The system is a full 3" setup with an AEM dryflow filter.
The rest of the intake "system" is an Eaton M62 supercharger off a Cobalt SS/SC. It's mildly ported and runs a 3.0" drive pulley, vs. the stock 3.35". The manifold is ported and has the dual pass end plate system for better charge cooling. The heat exchanger radiator is a large CXRacing unit that required the stock A/C and radiator to be relocated for clearance. The grill opening below the bumper was enlarged for better cooling.
This thing MAKES POWER!!

This is very impressive. More photos please. Is yours an automatic? If so, do you forsee any problems with the added power? I ask because GM turned down the HP for the auto tranny's. Your setup could be the start of something big. There should be a lot of Cobalt SC's in junk yards, so parts should be available. Personally, I never liked GM's idea of adding forced induction to their smallest motor. If the 2.4 makes more power naturally, then why not build on it?
I am certain that this should generate a lot of interest!

Can you fit a larger intercooler and up the boost?? Or is the intercooler already THAT large. If so, dyno it. That would be a great upgrade for the 2.4's
I forgot to add, is the SS bumper better for airflow, maybe you could get one?
