Hi all, newbie here.
I've been racing with my kids since around 2017. We started with stunt tracks and then got a super 6 lane raceway. Drag racong is what really got me hooked into the hobby.
I recently completed my first custom drag racing setup. Its been in the works since 2022. The final piece was a digital timing system, the Slanman Customs dts-2.
I already had a functioning start gate with wireless release so I opted to only use the finish gate. I fabbed a bracket to mount the micro switch from Slanmans start gate to my existing setup.
I was so excited to finally be able to accurately compare my cars and establish time based rankings.
Unfortunately, from day 1 I've gotten a lot of variance in the times. As much as +/- 50 thousandths on back to back runs. I originally thought it must be shortcomings of my start gate or track and set about improving anything I felt was a weak point. After covering all my bases I tried it again last night with the same results.
I contacted Slanman and he has been responsive, but we havent figured out the issue. Hopefully someone here can help.
I recorded 3 consecutive runs last night. The first two races I used the pro circuit funny cars as my test mules. I got 2.111 (King Kenny lane 1) and 2.119 (John Force lane 2). Then 2.140 to 2.145 no lane swap. The last race I swapped John Force for the Back to the Future 3 time machine. This time King Kenny ran 2.097 in the same lane.
I can't understand how its varying by 43 thousandths on back to back runs, same car, same lane. This is using a spring loaded drop gate with a door lock actuator pulling the release trigger.
