Tires are some basic Dunlop Direzza street tires, 205/50/15. 45psi and all, I didn't lower the air pressure or anything, just went to the track and lined up. The 60 foot of the 15.02 run was a 2.265. If the pipes continue to be a problem I'll certainly look into those clamps. You can see from the engine shop up top that the pipe going into the throttle body is clamped before the bead roll, just completely slipped my mind to fix it before the track.
