Mid to high 14s, probably high. It's 10 hp down on the dual cat car, and it has the 2.77s vs the 3.27s. I'd say low to mid 14s for the dual cat car... That is assuming a decent driver/launch, a good low altitude track, and a car in decent tune.

I've got the same car (single cat), I'd lean towards high 14's, low 15's in stock form.

 

Like a ROC,

See my answer on the TPI board to this question. Car was completely stock, with no timing changes when I went 14.6. Could have gotten more out of it with a good tranny and adjusting the timing, but I broke 5 teeth off the 2.77 ring gear and it was cheaper to buy a 10 bolt with 3.23 gears so I never did find out how fast the 2.77s would have gone.
