This video looks like it shook the tires pretty good. You can see it on the track too. How was the clutch set up? The way it left, based on the spin on the hit, it could have been a little aggressive and that would cause the shake if you guys were running it rich causing the power to be down at the beginning of the day. With the funny car we learned it is better to be a little loose on the hit and set the finger weights to have it come in as the RPM and the tire speed get up. Another big thing that affects us is tire pressures in regaurds to track condition. However, either way, it is great to see you get it out there Jimmy! Congrats!
