i thought the compression was at 8.something:1 atleast thats what i've read about it. sure u didnt get the compression number wrong?

 

thats straight from GM i didnt edit it at all just copy and paste

 

yeah there ya go

 

I can't wait to drive one! Anyone have an estimated 1/4 mile time?

 

SCC only pulled a 15.3 with the ION Redline, but they had quite a few problems with their preproduction model, mostly a bad tack. Hopefully all these get fixed for the Cobalt and it can run mid to high 14's at least.
