Default convert 1/8 mile to 1/4 mile times? estimate?

I ran for the very first time last night. And even though the track was horrible and I couldnt drive i would still like to know what my times would convert to if it was a 1/4 mile instead of an 1/8 mile.

my 60ft: 1.92
my reaction was .9211
my 1/8 time 8.551
my 1/8 mph 85.564


Thats all i can remember. I spun 3 times during this run even with traction control on.

Most people use 1.55 as the multiplier but I use 1.57, I've found it's closer to my actual 1/4 mile times. 8.551 X 1.57=13.42.

1/8 Mile Conversion

Here's the link that will do both 1/8 to 1/4 and MPH

^^ that thing was pretty close for my car

Your 1/4 Mile ET is 12.76 seconds computed from your vehicle 1/8th ET of 8.141 seconds.
Your 1/4 Mile MPH is 103.97 MPH computed from your vehicle 1/8th MPH of 83.85 MPH.

Actual 1/4 was 12.783@105.65

When I had a stock stall that chart matches perfectly, but now that I can get out of the the better I'm a little faster in the 1/8 than the chart says based on my 1/4. Still only about .2 off, though.

Almost right on for mine too.
About .08 off the list above.

60 ft - 1.760
1/8 - 7.554@97.93
1/4 - 11.703@116.08

60 ft - 7.061
1/8 - 7.52@97.80
1/4 - 11.674@114.92

Apparently hurt the motor that day, pressure in the crank case and 5 and 7 @ 85 psi. Should run good on all 8.
