I was told that for every tenth of a second you trim off of your 60' it amounts to two tenths off of your 1/4 mile time. Is there any truth to this?

 

I don't think it's an exact mathmatical equation given the other variables but I have consistanly seen 1.5 to 2 tenths at the big end gain from a 1 tenth gain in 60' times.

 

Thanks Dave. I kind of figured it was an estimate. That makes me feel better. I ran a 13.2 with a 2.4 60' on a stroker and was feeling like WTF

 

Yeah its a little over a tenth for me, for instance with a 1.98 60 foot my car ran a 12.5, but with a 1.72 I ran a 11.92. Almost 3 tenths off the 60 and almost 5 tenths off the 1/4. (this was the same night)

 

Our cars seem to follow the one tenth two tenth rule. Be interesting if someone actually did the math for a more exact correlation.

 

It depends a lot on how the car pulls up top. My LS1 car in it's current iteration is a .1 to.1 ratio.

 

my cars would usually see ~1.5 to 1.6 for a .1 change in 60'. the reason for this is, not only do you cut .1 off your total ET by running that much quicker in the 60', but because of the better acceleration through the first 60' you are moving at a faster mph when you start the next 1260'.
