I went to my local drag strip tonight and ran an 8.69 at 83mph with a 2.04 60 ft. What would be a good guess for my 1/4 mile time?

13.4 All you have to do is multiply your 1/8 mile time by 1.55

I use 1.57 seems closer on a streetcar.

With your 60' time, I'd bet your conversion factor is closer to 1.55. It varies from car to car but most fall within the 1.55-1.58 range. My car hooks and 60's fairly well all things considered so my conversion factor is ~1.575. 7.66x @ 88.5 turned into 12.07x @ 111.82 on a 1.59x 60' time.

I really need to get that 60ft time lowered. It was my first and only pass of the night on a track that I've never run on. I staged a little low for fear of spinning. I'm pretty sure it's capable of 8.5X's or maybe even 8.4X's. My reaction time was .337.

My 8.69 turned into a 13.36, so 1.53 for my car.

I'm thinking this is closer to my car as well. I hit 13.4 at another track before I put the Headers on. Granted, that I still need a tune, I still can't imagine getting no gain on longtubes.
