100lb rule of thumb
Is the old "rule of thumb" of 100lbs to a .1 still close. I have used the "Wallace Racing" type of calculators, but was looking for someone with actual testing. I know there are many variables, but so were there years ago. My application is approximately 3400# low hp auto SS. Looking at moving up class by comparing weight for class and difference in indexes.

You need to try it. My car will pick .010 for removing 125 #. 3170 to 3045.

Re: 100lb rule of thumb
The Wallace Racing formula is dead on for my car. 100# = .1 seconds I way off.

Re: 100lb rule of thumb
My 12 second car picks up .30 with a 225LBS removal. My BBC S/G car picked up .08 with a 100LBS removal.

Re: 100lb rule of thumb
Depends if this weight is rotating weight, or dead weight on the body.
