One tenth reduction in 60ft equals.....? On average, what does:
one tenth
two tenths
three tenths
reduction in 60ft times equate to in et reduction. I know it's more than a 1:1 ratio, but does anyone know what it'd be ?
Say you ran a 1.86 60ft en route to a 11.37 ET, what whould a 1.76 60ft get you? A 1.66 60ft? A 1.56 60ft....you get the picture.

So , does that make it .1=.2, and .2=.4, right....so , where is the point of diminished returns? Is there a point where no matter how low you get your 60ft, you won't get a lower ET? I guess thats a hp/aerodynamic question,there.

1.86 with an 11.37 would be a super bad 60ft, 11.37 should be about a 1.5 50ft. around 117 mph. If you ran a 1.86 with 11.37 et you'd be running like 130 mph
i need for 60 in my dies and 10s NA here we come

Suppose a stock F-body has a 2-second sixty and a 13-second ET. A Pro Stock car has a sixty time near one second and a 6.8 second ET. Can you therefore conclude that one second off your sixty is more than 6 seconds off your ET?

It only works on the same car & engine. You can't change 1000 variables & get an accurate result.

The first 60 ft takes more time to travel than any other measurement in the 1/4 mile and is the most important, obviously if you gained .05 in the 60ft and only went .05 fast in the 1/4 it wasn't as good of a run after the 1st 60ft.
There is no set number .1 60ft = .2 1/4, but all things being equal any improvement in 60ft should produce a gain of more than 1-1 in the 1/4 ET.

If you improve .05 in the 60ft you should always gain more than .05 in the 1/4 mile.

If the 60 ft improvement is due to more power I can see the theories working but if it's due to just better traction , as it was in my case, the improvement will be linear.

Looking at the time slips, the intervals between the 60 ft and 330, 330 to 1/8th mile and so on all stayed more or less the same on the runs which means the runs after the 60 ft were more or less identical. The only difference would be the 60 ft time and that exact difference would show up in my final ET within a 100th of a second or so.
If the 60 ft improvement is due to more power I can see the theories working but if it's due to just better traction , as it was in my case, the improvement will be linear.

If you pick up .05 in the 60ft and run the same ET at the 330, that meant it went .05 slower from the 60ft to the 330 mark, which without a doubt means the car went slower from 60ft to 330.
60ft time with all things working will always be greater than 1 to 1 for the simple fact it takes the longest to travel the 1st 60ft so the gain at the end of the track will be greater than just the gain at the 60ft mark.
Take two cars that run the identical ET down to the .00001
Have one run a 60ft .1 faster, if you think you'll just have to run .1 faster in the 1/4 to catch him you're wrong.
