what would be a good delay box starting out number,i know a lot plays into it,where you put the car in the beams,tire size,tire pressure,rear end ratio,rear tire size,how you see the tree,left lane or right lane,

How fast is the car and the 60ft? Hard to guess cause everyone reacts different and not every starting line has the same roll out but might be able to get ya somewhat in the ballpark.

A lot goes into this but with my car doing 1.25-1.27 sixty foot times I'm set at 1.055-1.065 but everyone car, tire size, and suspension is different. Test n tune is your friend for getting it zero'd in.

I need 1.10 in mine, torqueflite, 1.26 60 ft, 24.5 tall front runners, leave at 5200 off a 6200 stall, 8.90 ETaverage, 3065 lbs, 33 x15 slicks. car weighs 3065.

Set it at one second and go from there.

What kind of car, weight etc and what amount of power. No matter whats said here you will need to make laps to find what works for you. A lot of factors as you say from car reaction to rollout to the human reaction a ton of factors. FWIW my Cuda was 1.140+- usually the dragster is 1.170+-

Are you switching from leaving on the bottom bulb and going to letting go of the button the top bulb?
If so what was your average reaction times on the bottom bulb?
It is decent(winning some races) try adding 1.0 and go from there
I'm old and slow so I have .985 in my box with tall front tires

thats how I started out.

10.50 car, .965. As has been already mentioned, all combos are different.

I set mine at ........
oops shouldn't say anything

I only run 1/8 mile,1.25 to 1.32 60 ft,28 tall fronts,i suck at foot brake or bottom bulb trans brake,trying to maybee go to a box or get out of racing,car runs 6.30s

When we were pro tree racing, we would be at a different place every weekend. I would roll some numbers in so it would be real green for time runs/TnT and leave it alone. We were looking for consistency, difference in the lanes, lighting, sun and shade, etc. For first round we would roll numbers back out to try to get the light we wanted, based on that information.

If you go to the same place every week, it should be easy to get a baseline number.

you don't have to hit it perfect the first time out, put it at 1 sec make a pass, do the math using your R/T adjust the box accordingly. it is going to take more than one weekend to the thing set

Buy a practice tree. Biondo final round is a nice one. I have a full size practice tree but haven’t used it in years

What is the problem on bottom bulb?

I have a practice tree im 58,so im getting killed at the track by reaction times

Doesn't matter what car, et, 60 ft, gear, nothing! Set it at one second and make 4-5 runs, doesn't matter if red or you set there, you're getting a baseline of what you and the car does. Add or subtract the delay to get to an .01 light, then work on consistency.
While setting in line, practice letting the button go on the cars lights up ahead of you.
I had a practice box hooked up in my car that worked off the delay box, blowed everyone's mind. I would do it ten times in a row, wait a little then do over. A lot of double 0s

thanks cudaman and all,i have to try something

I'm 65 and bottom bulb race. Adjust the car to you, not you to the car. Just react and then there are lot's of ways to get the car to react faster or slower to get your rt to where you want it.

You need to concentrate on focusing for the starting line
I've been through this more than once, I've raced at the track since 1964, wait until you get old and have to worry about age related brain issues FOCUS,FOCUS, FOCUS on that bulb, no matter which one your using

didnt go racing this weekend but was reading all racers was under .010 and a lot was .00 lights,and that was in pro class,these days if you dont cut a perfect light and run dead on your just a sitting duck.dont want to be a sitting duck or known as a easy win,i will only tnt till I see results or be like the other old mopar racers in my area selling there race cars and theres a lot of old mopar racers here selling there race cars

You could always turn it back into a street car, buy one of those chairs with a cup holder and an umbrella, and start going to car shows.

I don't think you should listen to that. I have time slips with soft lights from every racer around here. Buy a one weekend to Nhraallaccess, and see for yourself. Everyone's heroes, going .163. There are great lights, but mostly average lights. The better racers always prevail. As was mentioned, change the car, not you. Also, when you go delay, things really tighten up big time, so get ready. You either spend the cash upfront on the delay box equipment, or one bite at a time buying parts (mostly tires, converters and gearing), until the car is right for where you see the tree signal. Been there.

thanks leigh,car has a delay box

I've seen guys with .880 in the box and others with 1.140. Lots of variables. I have around 1.100 in mine.

Had a buddy, dead now, who would show up just before race started. No time runs, knock the tree down in first round, if red light just rebuy and adjust the box. He said why waste his time, he was there for the money. Many year track champion at different tracks. Had a rail and car. Was also very good before the box came about. So you either have it or you don't, the cream rises to the top.

At #2330 with a 23" tire if I leave on the launch control 3800 I have 1.080 in the delay...off the converter at 5800 I have had as much as 1.165.....front end is tied and I run the front tires at 45psi.

Magic number for me is always .986 in the box, if i go up or down it almost always ends up back there in eliminations. Turbo action brake in the 904 and a Moroso adjustable button with as little travel in it as possible.
