The small track up here in Victoria is only 400' long, so all you get is a 60' and a 330' time to go by.
On one run today, my Pink Pig laid down a 1.51 60' and a 4.392 330'.
What does that 330' time equate to as an approximate 1/4 time? I'm thinking in the 10.80 range.

All cars are a little different, the Easiest and most accurate way to figure it out is to compare it to your timeslips from a 1/4 mile track, like the info you got from pinks here at pacific.

Now that is a good piece of info to have. It'll get you in the ball park of were you should be. Now that I find I'm .3 off in my et per 60 ft. vs mph , it's back to work
