Well some body i know in my area was talking to my brother the guy drives a stage3 srt, but him and my bro got in to it cause this guy said stage 2 only ads 10 hp to a cobalt. this guy is full of it right.

 

Stage Ii Adds 45

 

This is from the GM website:

Supercharged Stage 2 System
Take it to the next level. Get the performance you need out of your 205-hp engine with even more power through the midsection of the power curve. The Stage 2 System includes a two-piece performance pulley, performance calibration, four injectors, belt and fasteners. It increases your engine to 241 horsepower and 218 pound-foot of torque.

 

He could be referring to the fact that it adds about that much over the gm stage 1 kit... not a stock cobalt

 

I have GM Stage 2 and here is my dyno. Show him that!

 

is that stock + stg 2 on it?

or did u have the injen cai installed as well ?
