I know, practice, practice, practice...

My question would be has anyone found practice trees, or software http://www.startingline1.com/ any help?

Just starting in bracket racing, and still working on the car, but I know the car is only 1/2 of the problem.

 

If you are not red lighting try adding a little more air to the front tires. Should help a little bit. Like you said though, main thing is practice!

 

The online reaction timers are nothing like being at the track. Even the good handheld reaction timers are good to practice but you also need to know how your vehicle reacts. If I had a handheld unit and plugged in my vehicle reaction time, if you practiced on it then went and ran your own car you would probably get a terrible RT because your car reacts so much slower than mine.

Reaction time is broken down into vehicle reaction time (VHT) and driver reaction time. The only way you can find out VHT is through lots of practive. If you used a practice timer, set the VHT to .000 and got consistant .000 - .010 RT then go to the track and get consistant .150 reaction times then you know the VHT is roughly .150.

You'll notice a difference in RT between normal and LED lights. You'll also notice a difference in RT between daylight and night racing.

The best that you can hope for is to get consistant lights in the .000 - .050 range (.500 - .550). Even better is if you can keep them all less than .025.

 

Thanks for the replies...

Was at the Pro Hot Rod and Muscle Car Nationals at Bowling Green this past weekend.

Nearly every single index race was lost at the starting line. Just goes to show how important RT is...

 

It's kind of like bowling - do the same thing every time until you get the same results every time. Then change one thing at a time to bring the results where you want them.

The hard part is - doing the everything the same every time.

 

That's one thing I tried doing this weekend, try to cut a better light which I failed to do lol. Only one I remember off the top of my head was a .470 red light

 

One thing that suprised me was the amount of people coming in under their index this weekend. A lot of races lost because they broke out.

Part of that was the drastic changes in weather. The temp was varying by 15 degrees from day to day and even from morning to afternoon. The humidty kept varying as well.

I can see why some people use a computer to keep track of all the variables.

The other thing that suprised me was a Viper that did a wheelstand for at least 100 feet.

 

holy crap!!! a wheel standing viper?!?! thats pretty damn cool. a ton cooler than the 13 second ones at my track!

 

I'll post a picture after I get them developed.

There were a couple of cool 3rd gens there to, as well as a bunch of early Firebirds and Camaros.

 

Cant remember where i picked it up...maybe on old how to dragrace article in CHP or something....but with my auto tranny i stage and get the car all loaded up...then focus solely on the third yellow light....the instant i see that baby light my left foot comes off the brake....been a while since i have been to the track but that technique seemed to help last time i went.
