Well, first off whatever the NHRA does it will be stupid and wrong, like make the add weight to the cars. That will slow them down for a minute, until they figure out a way around that, then they will be heavy as fuck and fast as hell.
I really don't know how you can slow down a class like this, the only rules are the safety rules, that's it. You meet safety and besides that its run what you brung and hope its enough.
So right now they are legal to the letter of the law so the NHRA is going to look like a fool no matter what.
If they don't find a way to slow these cars down by the Shakedown at Norwalk in October you could see these guys hit the 5.30s because Norwalk is a better track than STL...
