Well now, seems GM liked this little idea of the Stage kits to add power to their sport compact cars. I guess they have to do this to try and help keep up with a STOCK SRT-4. I almost put this in war stories.



"GM Performance Parts is adding some extra juice to 2.0L Ecotec-powered Chevrolet Cobalt Coupe SS Supercharged and Saturn ION Redline by introducing two supercharger kits that generate significant power gain at the wheels. The Stage One and Stage Two performance upgrade kits provide an additional 31 and 36 horsepower respectively. “These stage kits are aimed squarely at the hard core enthusiast looking to boost the power of the already charged-up 205-horsepower 2.0L Ecotec engine of the Chevy Cobalt Coupe SS Supercharged and Saturn ION Redline,” said Nancy Philippart, executive director, GM Accessories. “They deliver increased horsepower and torque throughout the operating range of the engine.”

The Stage One Kit with a manufacturer’s suggested retail price (MSRP) of $500.00, includes higher-flow fuel injectors and an ECU calibration to provide a 31 hp boost to the Cobalt Coupe SS Supercharged and ION Redline Ecotec engine for a total of 236 hp and 205 lb.-ft. of torque.

The Stage Two Kit (P/N 17803229), with an MSRP of $750.00, yields more power through the middle section of the power curve versus the Stage One Kit. The Stage Two Kit includes the parts available in the Stage One Kit and adds a smaller supercharger pulley and drive belt, pushing the engine alive with 241 hp and 218 lb.-ft. of torque across a broad engine speed range.

A Stage One to Stage Two Upgrade Kit (P/N 17803230) is also available for an ION Redline or Cobalt Coupe SS Supercharged with a Stage One performance upgrade kit already installed. This kit converts the Stage One to Stage Two, increasing performance from 236 hp to 241 hp and has an MSRP of $400.00."



Hmm, they even have a s1 to s2 upgrade kit, just like we do.
I like where it says "These stage kits are aimed squarely at the hard core enthusiast looking to boost the power of the already charged-up 205-horsepower 2.0L Ecotec engine of the Chevy Cobalt Coupe SS Supercharged and Saturn ION Redline"

Now that's some hardcore enthusiasm. Even with stage 2 they are only at 241 hp. Although 36 hp for $750....

yeah, but remember, our stage kits werent realy that spectacular until S3R either....stage one was a whopping 10 hp and S2 gave you like 30 some more....granted, yes,we STARTED at a lot higher HP than the Cobalt, but still the stage kits were kinda overpriced considerng the gain....shit, a wideband and a map clamp and WGA can be had for nearly the same price as S1, but it can get you S2 numbers....lol

Here's a link to what the PowerWorks blower kit is putting down on a built up 2.0L Zetec engine in a Focus. They're using the same Eaton M62 blower and it's also intercooled.

If they bumped the rev limit a little more it might be putting down around mid-270 hp to the wheels (torque is going to be lower than a turbo because the supercharged is belt driven and eating up some of that power). I had guessed it before and I'd bet it holds true, but unless they go really wild with modifications and upgrades I doubt many of the current S/C Ecotec's will get over 260 whp, which is still fairly impressive for a small blown four.

very pricey for what you get. Has anyone heard anything from a SS owner? Are they excited about this?

The difference between Stage 1 and 2 is $250 and you only get 5 hp that kinda sucks.

Chevy is going to have to change something around, because until they do, people will get stuck on the math of the extra $250=5hp. What person in their right mind would pay that?

yeah, but your just talking about PEAK hp gain.....PEAK doesnt mean shit. it made substantial gains across the board.

hell, i could make the same argument with map clamps on our cars....a clamp and a good dyno tune and a wideband to keep tabs on it will runs you a total of around 400-500 bucks, but people dont complain about it, cus they see the graph and it makes more sense to them...when i got my map clamp installed, it only gave me like 10 HP peak gain, but in most of the dyno graph, i gained like 15-20 hp and 35 ft lbs of tq compared to the old graph.

so if you ask me, what GM SHOULD do is stop marketing the peak gain figure and start marketing the rest of the powerband and the unit's response.

:rofl: You don't spend too much time around people with small naturally aspirated four-bangers, do you? :lol: I get you though, and they should push the total power curve rather than peak gains. I could dyno one of their S1 cars and bounce it off the rev limiter and it would show a bigger gain from the spike than their S2 kit, but that doesn't mean it will be faster.

agreed. i love seeing the turbo civics have HUGE spikes in power for 500-1000rpms (1/8-1/9th of their driving range) but on either side torque and hp is mediocre.
