Barnstorm has a very good point, the MPH change is probably relative to the aerodynamics of the car..




one would think frontal area would play a big role?? and now that I look at it I guess it does.

69 Dart aerodynamic as a brick 132mph to 163mph = 31mph gain

4link dragster 149mph to 182mph = 33mph gain

2002 Firebird 140mph to 177mph = 37mph gain

guess I should edit my last post!
