After getting my pulley and Fipk on, see pwr numbers in sig, I knew I would get a 12 sec pass, but with only a 12.930 I was very dissappointed. I only made 3 runs, and the last one I missed third and let it cruise out. However a fellow Cobran whom Ive learn to know from the past two trips to the track gave me a few tips and how to on launching the IRS, I simply told him, here are the keys I want to know what she is capable of. He ripped off a 1.975 60ft time and a 12.616. My 60ft time leaves some to be desired but just need to practice more.
