High 17's - low 18's
best bet is gut everything possible, run bald tires and small light rims. doing so and providing your car shifts well will get you into the 16's unless you have a freak of an engine and even more of a freak tranny.
Best bet is to get as many runs as you can and try different things to net the best time. just dont neutral drop.
Good Luck and post your results!
