Ok, all this talk of dynos and theoretical rwhp is nice, but who has taken their Z06 to its speed limit? If you have hit the rev limiter in 5th let's hear about it. When I did it, speedo read 177, but I've been told that at 6600 rpms I may have been going about 181. Not bragging-- much-- but I just want to know who else is as whacked as me, I mean my wife (she was in the car both times that I took it to an indicated 177)! These cars are AWESOME!
