1st time at the dragstip
My best time
Reaction - .711, horrible, I know
60' - 2.245
330' - 5.873
1/8 - 8.855
1/8 MPH - 83.908
1000 - 11.395
E.T. - 13.517
MPH - 108.80
So if I wouldn't have had such a bad reaction time, my other runs were around .25, I would have been close to 13.00

For you to get a better run it looks like you gotta nail that 60ft. With the type of power you have you should be able to get closer to or under 2.0

+1, you'll need a 1.8-1.9 to get a better ET than what you have

RT is completely irrelevant...
The Best of Mercedes & AMG
It's surprising how many folks have the ill-informed opinion that somehow improving a RT will meaningfully improve the corresponding ET, or somehow change that particular run's trap speed.
RT doesn't affect ET or trap speed, period. Even if you don't go to the track, you can still see plenty of videos online where guys are trying to nail a good run with a car (not racing heads up), and sit at the line for a good 2-3 seconds after it goes green, getting their rpms up where they want for that particular launch. Does that add 2-3 seconds to the ET or hurt the trap speed? Nope.
The OP's run is a good one for a first time at the track, and I'd expect he'd measurably improve (assuming similar track conditions) with more experience and trying different techniques, tire pressures, etc. Improving the 60' will be the best area to improve ET, but will probably cost a little bit in the trap speeds. My $0.02.
Practice to increase your driver reaction time in a drag race whenever you get the chance. Most professional drivers will tell you that this is the most important step in improving your quarter-mile times. Every driver and every car is different, and they are affected by variables such as turbo lag, tire type and the type of fuel used.
Every 1/10th of a second delay can affect by one car length the final results.
RT is totally relevant and I have not seen a single instance where it is NOT??? This is why they use a Pro Tree and a Bracket Tree. This is why they use a tree period since it helps determine just how fast you react to get a launch and then the 60 foot measures your hook-up and how fast the car is getting out of the hole. A poor reaction time and poor hook-up (60foot) = slow times.
but certainly, RT does not affect your trap speed in any scenario i can think of

+1, but in his case, a 13.5 run at 108 shows me his car has some oats on the high end and is pulling hard after the 1/8th mile. His 60 foot and RT could BOTh be improved.
it is hard to cut 2.0s on street tires. i just looked up my best, and when i ran a 13.0 at 109 i cut a 2.15 or something.......and was really rolling into it. hopefully in a month or two, i'll be pulling some 1.7s with Hooley's DRs.

For example in a 13.00 dialed in bracket , you can not go faster that 13.00 , or you lose anyway. If two racers both dial in 13.00, then whoever car runs the closest ET to 13.00 WITH combined RT time wins.. If both racers RAN a 13.05 ET (tie) but one had a .10 faster R/T time, then he will leave the line first and finish first. Our time slips will still show are ET time and R/T time seperate. ET is what it is and R/T is still seperate.

To the best of my knowledge, bracket racing doesn't utilize RT in determining your ET, but it (RT) most certainly makes a difference in determining the overall winner - which is usually printed on the bottom of the slip. I've seen plenty of slips where the lowest ET car didn't win, because the driver's RT was worse enough to result in a slower overall (combo of RT & ET) time.
Where's cruzin when you need him...

EDIT: Exotic metal's got it right and beat me to it - well said. In your scenario where both ETs tie, however, if the one driver crosses first (due to a lower RT) it isn't a tie in the race - the driver who crosses first without breaking out wins.

All due respect, for purposes of analyzing his time slip and areas for improving his ET and trap, RT isn't relevant. Improving RT will only make him a better racer...
Agree that his 60' and RT can both be improved - but only one will improve his ETs. Also, his 108 trap makes sense in the context of his 2.25 60' - if he improves his 60' by a couple tenths, his ET will get better but his trap speed will likely go down. 13.5 isn't particularly quick for a car with his mods, which makes sense due to the 2.25 60' and high trap. Those three data points tend to move in concert, assuming no additional mods and similar DA & track prep.

I use "overall time" differently, to signify reaction time plus elapsed time - easy to think of, it's the total time from when the light goes green til the car crosses the line. Handy in racing to determine a winner, but as hooley correctly points out, elapsed time only starts once you trigger the beam - RT can be .001 or 10.001 and your ET can still be 12.5, as an example.
Great vid, BTW.

Also as 99.99% of us know: If you leave early and red light the tree that will not make you faster. If that was the case I would have -2.00 RT's every time. lol
vacuum.
Remember for every .1 second on the 0-60 feet that's .2 seconds on the end of the 1/4.
If you can make your 0-60 feet in 2seconds that's .48 seconds of your time.
Good luck!

Not sure what you mean, launch with the supercharger engauged?? How do you do that. I tried launching at around 1000rpms, but it would just spin the tires.

The next time you head out there give me a bump and my buddy and I will do our best to meet up with you. I'm no expert but I'm sure I could give you a few tips while out there.

I just realized i was confusing the overall time with the ET from my bracket racing time slips. i stand corrected. thanks guys
