707 Hell Cat, what does it mean?

So an 11 sec 2014 srt with an add on supercharger has to have a roll bar, but a 2015 hellcat running sub 11 does not? Genius. I guess in the NHRA some things are more important than driver safety.

I hear ya. Have you ever been in a discussion with someone who runs in a "stock" class in the NHRA? Nothing makes sense!
