A little help from those smarter than me

Mr Jeff, you are a funny guy, and also correct. Laid out below shows the problem is strongest @ 6#/hp class.


6.0# FSS/C 9.65 & FGT/A 8.80 = .85 Difference in index @ same race weight

6.5# FSS/D 9.90 & FGT/B 9.20 = .70

7.0# FSS/E 10.05 & FGT/C 9.55 = .50

7.5# FSS/F 10.20 & FGT/D 9.90 = .30

8.0# FSS/G 10.25 & FGT/E 10.00 = .25

The difference in FGT is crazy strong. For those who are not understanding or aware: The numbers above are basically a penalty for switching a motor into a different body with the same race weight. Now, I have switched the same drivetrain from a 3rd gen Camaro into a 05 Cavalier, and I believe it is .08 to .10 better. Unless you are switching from a 60's full size wagon, I do not see how it is possible to gain more than .15 by just switching bodies given the same weight.

Jeff had shown the problem from a weight perspective, and I have it in an index perspective. But anyway you look at it, it's not right.

Hopefully someone @ NHRA will see that there is a problem/mistake here, and fix it.
