My Mystique, bone stock (O/D was on too

) ran a 16.8 @ 83mph. Unfortunately, it is an auto too...

As I found out after I went to the track, turning O/D off makes the car go into a "sport mode" I've played around with it a little and it does seem to help. This spring we'll see how much better it really does.
Your car stock would run about that...
As Russel said, a mid to low 15 with those mods wouldn't be too hard.
Someone posted a while ago and said their ATX/V6 contour put down 155hp to the wheels (Or somewhere around there) They had similar mods as you suggested.
