What follows is a re-statement of an old post I know many of you will find interesting.

Many times as we discuss our drag racing interests with non-racing friends and family, their eyes glaze over as we mention quarter mile times, 60-foot times, and other truly important numbers. All they usually want to know is the 0-60 MPH times. No doubt because of automakers and auto writers focusing on this, it has become the de facto yardstick that the general public uses to compare different cars and setups. Of course, our racing timeslips don't provide a 0-60 time, because it's not relevant. But what if we could back-calculate that?

As an engineer by training, I thought about that long and hard. I decided that if I made some simplifying assumptions, it wouldn't be hard to get an estimate of the 0-60 MPH time from several numbers that timeslips do provide. In particular, the 60 foot time, the 330 foot time, and the 1/8 mile time all bracket that interval during which the car accelerates through 60 mph.

I created an Excel timesheet and uploaded it here. Clicking on this link will download the spreadsheet. Open it up in Excel. then just enter the 60-foot time, the 330 foot time, and the 1/8 mile time from your timeslip, and it will do the rest. It's not exact, but it's pretty darned close.

For the mathematically inclined, a discussion of the calculus behind the calculations can be found in this old thread on CFOT. Enjoy.

My Excel is corrupted and I haven't used in years anyway, so here's some numbers you can punch in from 3 timeslips and I'll look on my HPTuners scans to see how well they match.

Slip 1
60' - 1.515
330' - 4.414
1/8 - 6.892 @ 101.39

Slip 2
60' - 1.484
330' - 4.477
1/8 - 6.969 @ 98.56

Slip 3
60' - 1.542
330' - 4.449
1/8 - 6.913 @ 101.27

Pretty cool says I'm ripping of 0-60 times in just under 5 seconds. Not bad for a stock 22 year old car on street tires. As far as street cars go that is still quick.

0 - 60 time: 2.65 sec
0-60 dist: 145 feet
1/8 Speed: 97 MPH

0 - 60 time: 2.81 sec
0-60 dist: 158 feet
1/8 Speed: 99 MPH

0 - 60 time: 2.70 sec
0-60 dist: 146 feet
1/8 Speed: 98 MPH

Thanks Gary.

So here's the 0-60 times from the scans.

Slip 1 - 2.73
Slip 2 - 2.81
Slip 3 - 2.75

Now a little more info to either clear or muddy the results.

Slip 1 and 3 were both at Sacramento with -536' DA. I was having trouble with mis-fires due to bad plugs and KR pulling timing either early or late on every pass. I also believe their 1/8 MPH lights are off slightly, since I consistently trap over 100 there, but only occasionally at other tracks. The 1/4 ET and MPH for those slips were 10.80 @ 124.87 & 10.80 @ 126.84.

Slip 2 was at WHP (Firebird in Phoenix) 2 weeks later with new plugs. The DA was 989' and the 1/4 ET/MPH was 10.94 @ 125.35.

So the 0-60 calculator was dead on for Slip 2 when the car was running correctly, yet still pretty close when it wasn't.

idk probably the same as some of these 10 second guys.... 2.5-2.7

I get asked that all the time and have no clue. I do go 0-113mph in 6.00 seconds though.

Mine is 2.6 seconds 0-60 per my HP Tuners scans when I cut a 1.4 60 foot time, so similar to Hoxxoh's time.

Launch the car at frame 2999 - 1:33.685






Hit 60MPH at frame 3073 - 1:35.994





1:35.994 - 1:33.685 = 2.309 seconds.

I guess my little pump gas Camaro is around 2.65 as well...1.49-60'....6.81-1/8 mile @ 100 mph...not too bad for a 3740 lb. car...
