2015 Mustang Ecoboost K/SA?

If I'm reading it right, the 310-horsepower engine is factored by NHRA at 264 horsepower for Stock Eliminator. At 12.78 pounds per factored horsepower, it would be a natural J car, but I was looking at the K (13.0 pound) class because I'm wondering if the combo is one of those turbo combinations capable of making index without too much work.

13 pounds times 264 horsepower, plus 170 pounds, equals 3,602 pounds minimum weight for K.

The K/SA index is 12.65, and the record (which I would not be shooting for) is 11.39 @ 114.02.

Is my math right, so far?

Lund Racing has been 11.03 @ 122 in one with stock engine/turbo/manifolds/trans/converter, on street tires, in what appears to be a full-weight street car with air-conditioning and a license plate.

Does this combo look like something worth exploring?
