I have a 2011 Chevy HHR 2.2L LT, and I was just curious if you can easily install the supercharger kit from ZZP (for the cobalt originally) if not what are some options to give this ride a little more power. By all means I know this car is not going to be a speed racer but it could use a push! Is a trifecta PCM tune worth the$$?

 

Welcome to the site.

There is a whole lot of info here on the ZZP supercharger, including some How-to info - same with the trifecta tune. Just use the SEARCH tool at the top of the page and do a search for both of them. And be prepared for a whole lot of reading. :)

 

Thank you!

 

Welcome to the site! CJ had a 2.4 liter he super charged a few years back and he is very knowledgeable with the Trifecta tune. Maybe he'll see this and jump right in!

 

I can't give any advice on the install of the kit...I'm sure if you have the tools and are familiar with these sort of things that it can be done in a weekend. I can definitely say after this past weekend that it is definitely worth the money! The power difference between a factory 2.2 or 2.4 vs the Cobalt with the SC is night and day. I was really surprised how much power the supercharged Cobalt has. If I ever get a few extra thousand dollars I may just have to do this upgrade myself!

 

As cheap as you can buy an SS now...I'd skip the hassle.... and just buy one.

Here's a good example...this one is rare to boot, they only made 200 of these, less than the SS panel.

120k miles is steep especially if it has the stock turbo...plus for me I have a few custom mods on mine that would be hard to duplicate on a new one, ie...shaved tailgate. If I didn't already own mine and was looking for a new vehicle I'd definitely look at an SS...although if I didn't have mine and was looking for a new vehicle I probably wouldn't opt for an HHR at all...

 

I say Supercharge it. It may not be the easiset, and definitely not easier than buying a SS, but it's different. That's what I go for. I have the Blower, Manifold, and a few more bits nd pieces sitting in my living room, waiting on the rest so I can put it all on.

From what I've learned from reading and talking to CJ, these things are screamers with a S/C. Going with the rule of thumb that 1lb of boost = about 10hp, and the factory pulley on the m62 making around 8lbs, a 2.2 5spd should be putting down about 210whp with just the S/C. CJ was putting down 256whp and 313wtq on a 2.2 auto. By the time I'm done with mine, I plan/hope to be making around 300whp

SS Fan, we've been over this, for those of us that already own a LS/LT, if we put in what a SS costs, we could walk all over a factory SS.
