Actually there are several z06 owners that have run 12.0x @117mph, with only drag radials! They typically dyno around 360rwhp. My 03 cobra dynoed 372rwhp. but the problem is my car weighs 600lbs more! But with a $100ish pulley My car is capable of zo6 times. Most z06's are running 12.5's at 113mph, Only the good drivers are able to pull the low 12's. this is the 02 zo6 405hp car not the 01 385hp zo6. the 01 zo6's comes down to drivers! jmho. But hey I'm happy, i spent $35K for the car and $1400 in mods and have 440rwhp! I think my car will give any stock z06 a run for it's money
