I enjoy jumping into bracket racing mostly in the sportsman classes or no box in my 2012 Dodge Challenger 5.7. Is anybody having success with late model cars being consistent? I try to heat soak and keep the car hot before each pass but it’s still moving the dial around 2-500ths. Car has headers, 3800 stall, 4.30 gears, drag radials and skinnies. Usually the 60ft is very close but around the 330 it’s moving around. Any input would be great.
