weight n reaction time

SmBlkFord · 07-18-2014, 08:23 PM

Anybody ever play with weight and reaction time ? Have tried front tire size,air pressure don`t do much, but have not had time to mess around with weight. Although I did take out 35 pounds and made a pass, thought it was -.020 off the reaction time, But track was closing and have not tried it since.

Unless you have a device to measure rollout (like the modules at Lebanon Valley Dragway) it is hard to say how the change affected your car. Removing 35lbs should only lower the reaction time by 0.003 to 0.004. Check out the rollout article on the Portatree website and if you have any questions, you can always give us a call
