This was my first time with any car. Not to bad, imo, wasn't really sure what to expect.
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

not bad at all. nice trap speed. sounds right on par. traction appears to have been a slight issue for you.

what were the track conditions? DA and temp and such?

chamm

Not sure on the DA, it was at Sacramento Raceway, so pretty low. Temps were around 75, traction was an issue, tires were pretty worn dunlops

Dingleberry

are you serious? are people not running low 13's with at least 105mph traps on a completely stock car?

Newzchspy

Not necessarily. His trap of 108 is really good GIVEN his ET, so it shows 1. He's not hooking or has a really bad RT and 2. He's making some HP up top (meaning he's pulling harder at the end.). If he had a better digg, he'd be in the high 12s for sure and this was his FIRST TIME(drag strip virgin). I think he did a good job, just needs practice. Most C32s running 108 or more Trap speeds are in the high 12s.

thegreatfnr

Good run, but RT does not directly affect ET. Now if you were shallow staging itd be one thing but thats not what your talking about.

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

Newzchspy

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

this is how I know you have no idea what you're talking about. no offense.

RT is completely irrelevant...

c32AMG-DTM

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.

Newzchspy

Why is RT irrelevant and if so in your opinion, why is it on every time slip I've ever had???

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.

jturkel

in his (Newzchspy's) defense, bracket racing does utilize RT in determining your ET. i've done this and it has affected my ET. however, this was when i was bracket racing. sometimes tracks are setup for different occasions and with different settings. most drag strips i've gone to do not normally use your RT in calculating your overall ET, but i have done a run or two (non bracket racing) where my RT WAS incorporated into my ET...

but certainly, RT does not affect your trap speed in any scenario i can think of

Newzchspy

+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.

jturkel

yes. i agree 100%. thats why the first thing i mentioned was that he was having traction issues with his 60' and his trap speed was on par. sounds like he just needs a little more practice learning how to launch the car and/or getting better tires for the drag strip....

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.

Dingleberry

You have no idea what you're rambling on about. Please stop spreading information that is not accurate...

I have raced in a lot of bracket events, some major and some local. RT, still does not effect the ET on the time slip, just effect who wins the bracket in most cases.. So, R/T is still not relevant to the topic of this thread or his posted ET time..

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.

c32AMG-DTM

jturkel - never been to or heard of any NHRA track that does it that way... would love to see the time slip of the run that incorporated (i.e. added, right?) your RT into your ET.

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.

c32AMG-DTM

Agree he did a good job, and there's no substitute for practice. I don't see him shaving 6/10ths off his ET just by nailing a better dig, unless he considers additional mods (DRs probably being the most useful in this context). He's already got a pretty good 60' for a modded car on street tires - most he could expect here would be about 2/10ths without switching to a really grippy street tire or DRs.

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.

Reaction Time has nothing to do with over all time at the track. you can cut a 000 reaction time and it will do nothing for your over all time. When the light turns green the clock only starts when you go. You could sit at the green tree for 30 seconds and still run a blistering time. If your going for your best time RT means nothing.

Watch this vid of our good friend Blackbenzz racing. You will see what we are all talking about.

c32AMG-DTM

Agree 100% with hooleyboy, assuming his usage of "over all time" means "elapsed time" (which I think it does).

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.

hooleyboy

I never race for reaction time. its the last on the list of important stats for me. Granted If I'm up against a car I want to beat. I will do my best to smash my gas peddle before the other guy does.

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

neihouma

I would suggest you to get a boost gauge and try to learn to launch on boost and not on
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.

bassn_07

Agreed. The next best mod for him would be to get into a good set of DR's if reducing his ET's is a high priority. Take it from me, Sacramento has some serious traction issues on Wednesday night drags when admission is $10...no VHT at all, and street tires tearing up the track. The only time I raced at Sac on a Wednesday night I couldn't get below 2.0 with my DR's. Never again will that happen.

Don't worry about your RT when starting off. Each time you get up there just concentrate on you launch and in time it will improve. I ran plenty of low 11's with my RT's at .5-1.0, do I care...no. I have my own agenda and I could care less what anyone might think at the track. Now if I was bracket racing or going heads up that would be a totally different story.

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

Newzchspy

That car is just brutal !! Thanks for the video!! That's the car that beat the Black Series!! Nice run BlkBenz. He barely spun, just hooked and went!!
