Title: Idiot guide to 1/4mile?
Post by: s3dubbin on July 26, 2011, 03:53:20 pm
How can you have a poor reaction time but still run a quick 1/4mile? Does the computer do its sums and work it out, if it doesnt count then whats the point? I know at inters you break the beam so really you could be sitting there for 2secs and still run a PB. Also this 60ft time is this just another measurement to record other than 0-60? Why so many variations, i like the 0-60 this 60ft time means nothing to me really? What is recorded with you boys/gals down south york and at the pod? Stevie.

Ignore the other car at the lights and leave when you are ready. As I understand it, a NHRA approved quarter-mile will time you individually.

Modern day 1/4 mile tracks only record your time once you have moved and broken the beam (same as @ Inters). So (like you say) you can sit there and go when you are ready and still record a good time..
60ft times are all to do with your launch. People who are into drag racing will concentrate vastly on this, as it has a big impact on your final ET (time). Every 1/10th second gained on your 60ft time is generally doubled by the end of the strip (so will be 2/10th quicker).
4WD cars and best with 60ft times, then RWD then FWD (same as on the road). But once slicks are involved, they can all take massive amounts off your 60ft time..

HTH  :happy2:

Best is when you let the other car leave first, but still beat it across the 1/4mile...

Cheers for the replies. So reaction time counts for nothing? My quickest time was my worst reaction time. Need to practice 60ft if it counts as much, would like another 0.2sec in my pocket. Stevie.

Reaction time needn't be your first concern when still learning. You can focus on that later.  :happy2:

Still wondering where the point of it is though? You can sit there for 1.2secs after light goes green and still run a 11.8sec run? Dont get it??? 10.6sec run, no? At inters there is no reaction time is there? What about pod/york, whats recorded?

reaction time doesnt say anything about a cars performance though, hence why it doesnt count.  All that matters is how long it takes you from stationary to the 1/4 mile

Ok got it, forget the reaction time. Cheers. Stevie.

Reaction time is all about racing the guy next to you/first across the line (ie Top Fuel boys).. For us mere mortals who want to see what our every day cars can achieve time wise, it's not really an issue..

No probably not but if you run once you will be addicted!!! Love it trying to knock 0.1sec off. Stevie.

Get that launch control ramped up and give it a go! Got to be done.  :happy2:

Stop it!! This hobbie costs enough as it is with out braking a DSG box!!!

All part of the fun! Learning curve. Even better when you get to rub it into the blue oval and griffen boys!

That is a very good point!! These K04 TFSI engines really are quite potent!!

You'll do well to do that mate.. I must of done over 200 launches with my DSG (most at Pod) on my ED30 and it never broke..  :rolleye:

That's a fair point! I remember when I first had it mapped I was sh*tting it about the DSG, two years on and the car does get driven its still A1! Even VW prob didn't think it would be this good! That's why the S3 only got it later on!

Reaction time indeed is not included in the elapsed time. 11.8 et is 11.8sec 1/4 mile.
Reaction time only plays a part in elimination rounds. There is when you set a time for your car to run but not beat, and the guy next to you does the same for his/her car. The lights go off corresponding to those set times and the winner is usually the driver with the best reaction time.
For example;
If I run pretty consistently at 12.8 and you are at 11.8. Those et's are selected and put on the glass of each of our cars. When you pull up to the line the lights are set to go off for me one second before they go for you. Then the first one to cross the finish line without beating their selected et's win the race. So this is when Rxn times come in to play.

24 DSG launches in one day is my record at Santa Pod  :rolleye: :driver:

The DSG can take it easily at stage 2+, it is when you go beyond stage 2+ that the gearbox can start to slip on the clutchpacks. :happy2:

I set off when I'm ready, rather than when the lights go green. The reaction time may be longer, but generally the ET time is better  :star:

Certainly will Dave..  :wink: Got a lot to live up to though  :scared: It does only have software though, so not really a fair comparison..
