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.

The Wallace Racing formula is dead on for my car. 100# = .1 seconds I way off.

My 12 second car picks up .30 with a 225LBS removal. My BBC S/G car picked up .08 with a 100LBS removal.
Your mileage may vary............... |

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

Re: 100lb rule of thumb
According to T-Ped on last night's broadcast from Pomona, every 10 lbs is worth a tenth!! If I could quit eating Taco Bell, I'd be 1.20 under in no time.

Re: 100lb rule of thumb
That was close for my old Jr Stocker. Depends on HP levels. I think Tony should do some research, instead of quoting 40 year beliefs. My car, 100 = 6 hundredths, in decent air, seven in like 4000' + DA. 50lbs is a pretty consistant 3 hundredths any time..
