I went to SIR and tried 1/4 miles once. I have a 99 G20t manual, stock but a sport muffler at that time. The best result I had was 16.9...something. And I had my friend (110 lb)sitting on the passenger seat, with don't know how many lb of stuff in my trunk, and motor oil with 3000 miles on it. So I think it wasn't that bad. Oh...I beat up a Civic on that race.
