You’ll see more power adders in the no prep or heads up classes than in the bracket classes. It tends to add even more complication to the whole battle for consistency.
In many of those classes you have to run 5.0 and quicker so yes power adders are needed. I even spent thousands on a nitrous kit in preparation to run that class. With the small tire limitations you need the power adder to make up for pulling power off the line. My dislike for power adders is probably a big reason I never ran the class.
