In my 13 year old stockish GT4 I ran a 15.85 1/4 mile @140kmh, on a hot night (29 degrees!) at Willowbank.
Given a cooler night, I think around 15.6 is normal.
0-100kmh is around 7.7 - 8.0 seconds depending on launch. Not that quick, because the car is so heavy. But the 3S-GTE has enormous potential and its easy to get around 300hp from it (205hp stock (ST185)) and drop that 0-100kmh time to around 6 seconds or so.
