We are going to be seeing fewer TF and FC entries if they don't get a handle on the ever-increasing engine explosions. The cost for the "average" explosion, especially for the FC class, is really eating into the car owner's budget. Sponsors will not be able to continue their support of the teams if every other run tops $50K-$100K over and above the normal cost per run due to an explosion. Also, just a matter of time before the insurance companies make the premiums so high that NHRA will be forced to charge the spectators more for tickets.
I'm not for slowing the cars down, I'm for finding out how to reduce engine explosions. Survival of these 2 categories depends on it, IMO.
