I'd say low 13's or high 12's.
My car STONE STOCK except for cone K&N and 17 lb. street chip went 13.30 on drag radials. It did have a flowmaster exhaust too, but I'm pretty sure it sucked. I pulled 1.8 short times, can't remember the mph, but I remember launching at 17 psi!! The only advantage I had was it was about 45 degrees that day.
