Ran a 14.20 on a really hot day in August. Car was run as I drive it everywhere, 351W, C6, 3:50 gear, 27" radials, full tank of gas and the stereo on. In this configuration, it's gone from Cleveland, OH to Boston nonstop except for gas and Cleveland to Charlotte, NC only stopping for gas.
My wife wheeled it to a 14.7 her first time ever seeing a dragstrip in person. I even had to explain to her how the tree worked!! Once she was able to catch her breath, she said it was a blast!!
