I've been looking at a CSVT and I'm a 3.8L freak and I have alot of experiance with V6 stangs. In the real world here is what they typically run BONE STOCK.

94-98's
5speed = 16.2-16.5 @ 84mph
Auto = 17.0-16.7 @ 81mph

99-04
5speed = 15.5-14.9 @ 90mph(yes, I've personally seen TWO crack 14's stock in good air and a good driver)
Auto = 16.2-15.7 @ 87mph


1996 Thunderbird LX 3.8L V6 with "bolt ons" -13.87 @ 98.9mph-
