Some interesting stats about class selection. Last year, out of the 292 finishers, one hundred eighteen cars finished Drag Week with a five day average above 11.50.

61 of those chose to do so in SME, or Street Machine Eliminator, despite knowing they wouldn't make the quick 32.

57 of them chose to do so in another class of their choosing, despite knowing they had little chance of placing in the top three of said class.


Pros and cons of running a class vs running SME.

The first run session of the day is class cars, for about an hour and a half to two hours. So if you are an early riser who wants to be in the first twenty cars down the track, maybe a class is for you. The caveat is, you are in the lanes with 6-9 second machines that do long burnouts across the line, and often break stuff, so those sessions may leave you in the lanes longer, and severely try your patience!

The SME session is second, generally about two hours after the gates open. So, if you like to sleep in at the motel, and hammer their continental b-fast before arriving, SME may work out best. These cars are all supposed to be slower than 10.00, so by rule, don't do long burnouts, and these sessions go pretty smooth, which means less time in the lanes.

The whole mopar springs moved in things allows you a number of classes to chose from Pro Street even, if you choose a big tire. Possibly Modified with a small tire,but definitely Super Street.
The problem is, Pro Street and Modified do not split between BB or SB, it's just one class.

So for your car, either SS/SB/NA or PA, whether or not you add nitrous, or SME.
