Magnuson has posted that the 1900 rotor set is good to 800 horsepower, so there's still a fair amount of headroom and you gotta' know that GM isn't hardly leaning on it in the 9 psi boost it is with CTS-V.
I'm sure he's just speaking out of the Eaton promotional info that goes into the advantages of the TVS design vs the traditional like still found on the GT500's. I don't think its going to be making any more hp then the CTS-V
I like most everything about it, but couldn't they save the gold bow tie on the steering wheel for the cobalt and put a ZL1 logo on the steering wheel just like they use to so with the first gen SS, RS, ect?
