Get the car dynotuned if you haven't already. You don't wanna have problems with engine failure later on. The mph is easily good for 13's. You just don't have any traction. I'd say that your car is capable of a high 13 sec. pass with DR's and decent track prep. You may even get a mid 13 sec. pass out of it. It's definitely got the power with that sort of trap speed.
