Ok what im kinda confused about is that my 97 tbird lx (4.6l) ran a 15.3 at the track with no mods, and its supposed to run a 15.5 or so (rough estimate) and the supercoupe (89-93) apparently runs about a 15.5, but wouldn't it run a lower time than 15.5 seeing as how the 89-93 sc has 210 hp and 315 tq, and the 97 4.6l has 205 hp and 280 tq. Also i live in austin texas so that probably has somthing to do with it. but theoretically shouldn't the supercoupe run low 15's like 15.3 or even maybe 15.2 stock?
