Big silly rookie question

[Mike Carr]

The Sedan 4 door breaks at 16.50, making it a natural BF/S, meaning it can also run A and C, with weight adjustments. The Sedan 4 door SE, breaks at 16.86, and will fit the same three classes. It's factory rating is 146, with an NHRA rating is 160. So you will multiply 160 x the class weight break, add 170, and will give you the minimum weight for each class, as follows.

AF/S 13 x 160 + 170 = 2,250 pounds minimum weight (seems highly unlikely that your car could get to the class' minimum weight. Class Index is 13.85 seconds.
BF/S 16 x 160 + 170 = 2,730 min wt. Class Index is 14.65 sec. This is the closest weight to the cars natural factory shipping weight.
CF/S 17.5 x 160 + 170 = 2,970 min wt. Class Index is 15.15 sec.

Hope this helps.
