Last night, I raised my best mph to 89.80. The cool air helped, but it was humid. Traction was really bad. On that pass I had a 2.5 60' and ran a 15.5. If I could have pulled a 2.2 like I did the last time, I think I would have been really close to running a 15.0. But not yet. Mabey next time. There was also a s10 there with a powerdyne supercharger, huge tires out back, and skinnies the front that only ran a 15.3. But that could be because he just bought the truck.
