Hz or Freq Classes

Why not have a frequency class in dbdrag or any organization for that matter?


How much more fun is 30hz and under class??

I used to run a 30hz challenge alongside my db drag events. It was pretty cool but dominated by 2 vehicles. I had to start adding power classing to it.

No. Psychlone is a type of sq format that combines an RTA score db score and install score.

I can see that.. i put in 8 minutes of thinking into the variables that might need attending to, and that would be one of the biggest!

It might be nice to see a 30hz and under class in Each dbdrag class... just for fun even?
