Tommy- Are you Dan's attorney? If so, I'll bet it's a full time job keeping that guy out of trouble! LOL.
Ernie- You're right. In a Cobra it's all about getting the power to hook up and that usually doesn't happen until 3rd. In a drag car it's all about the launch / reaction time because they're running slicks.
Dan- Make a small investment and go out and purchase some BFG Drag radials. You can get them in 15" and go with the 325's (although the 305's would be fine too). I've driven with both Billboards and drag radials and trust me, there is a big difference.
If you haven't been able to post anything better than 12's so far (and that's without a xmastree start), I highly doubt you're going to get into the low 11's without swapping out the tires and PRACTICE. Do you know what your rear is? You may want to think about launching in 2nd gear. If Tommy gets you off the line (which he will) don't panic and mash the pedal to the floor. Your car is much lighter and you have plenty of HP to get you caught up and pass by him by the time you reach the end of the 1/4 mile..........you just can't panic and spin the tires - and don't take your hand off the wheel to flip him off on your way by.
Both of you BE SAFE and have fun.
