Cobalt SS Dyno
I recently went in for a free oil change on my SS cobalt and a service tech asked me if i had dyno'ed mine yet. I replied no and he then went on to tell me that I should because he has seen them dyno showing 240hp and that the 205 hp listing was for inssureance reasons. Has anyone dyno'ed and can support this claim or is the tech just full of it?

240 wow i think thats a bit off. I got mine around 225 and a few others also got it into the 220's (stock obviously) like MarcS said most get it in the 210 region

You lose some power through the driveline.

the loss in horse power is largely to to the loss in the drive train, but the amount of loss is mainly dictated the the amount of Torque the engine produces. so the more torque the engine produces to lower the loss through the drivetrain will be. but the general idea is correct the whp will be lower the the crank hp.

there was a show on speedvision and they were haveing a competition with a ss, a VW and skyline ( don't ask me why they included the skyline) but the point of the comp was to tear down and trick out the car. the cobalt team consisted of a couple of guys from GM racing. getting to the point they Dynoed the ss and it only put down 199 at the wheels straight from the factory. So I wonder where all these 220 numbers are coming from. I have to imagine that these professionals would have the best equipment. and they would know what they were doing.

A dyno is a tuning tool.
