I still have a few more things to try with the Caltracs to see if I can get a little more improvement but I am curious if a vert change would help me? I currently have a 10" TurboAction vert in the car. For a couple of years I ran an 8" ATI (before advancing the cam). With the 8" ATI it ran a best of 11.817 @ 112.89 w/a 1.657 60'. Do you think going back to the 8" vert now would be wise? I just hated the 8" vert on the street which is why I took it out. Maybe a 9.5" Dynamic vert would be worth a try?
