Jayson's car is roughly 500-600lbs. lighter then your car sportsb4life7. Not to mention that it is well known that the Cobalt SS is underrated. They've dynoed them to 217whp on more then one occassion. They did this to keep up with the SRT-4. Though I really think that Jayson should've waited for the turbo model that is rumored to come out.
All in all he should enjoy the car though, as it has more grunt then his former car. Now he needs to learn how to drive it, as a manual car is much harder to launch then an automatic one.
