I have a 392 Challenger that has 465 to the wheel and brand new nitto infos 275 in rear manual tranny. I ran the car about 20 times not hot lapping the best i could get was a 12.9 @ 111mph. My reaction time was between .2-.4 all the time. I did everything I could think of most of the time traction control was completely off my best time was with traction control partially off. This was in VA at 60 degree. What is going on? What am I doing wrong?
