We did this on saturday, my friend with an 86 went from 16.4 down to 15.8 by the end of the nite. how i dont know. It was a fun day, cant wait to go this year.

Your R/T needs help. I hint: Go when the last yellow light comes on and deep stage.



Ken

Yeah, i kinda noticed that. Ive been going to race tracks since i was like 6. My dad used to sand drag a baja bug back in PR. So, ive seen how the tree works for a while, so i thought i had the hang of it. Wrong. Its completely different when you watch someone else do it.



Some guy told me to rev on the 1st yellow, to like 3k, the let go of the gas and immediately rev up to like 6k. By the time i do this the last yellow would be on, and just dump the clutch. havent tried it. cause i need the car to get back home, and go to work, etc...



Deep stage?? Whats that??

Thanx

Damn, your 1/4 mile times got worse and worse. I can't wait to get my tranny fixed so I can see what kind of times I can do. Your RTs look like mine did last time I took my car racing, except mine were under 1.00. :smilewinkgrin:

here is how i launch with the GTU. big smokey pro drag burnout in waterbox(gets street tires *gummy* ask silver93tt) then stage when i stage i hold the gas at about 7000-7500 rpm. once the third yellow hits i drop the clutch. my best RT was .516 i think only..... https://www.nopistons.com/forums/pub...IR#>/smile.png launching you will see your biggest improvement. my 60ft's also dropped from 2.5 to 2.2 not bad for crappy street tires https://www.nopistons.com/forums/pub...DIR#>/wink.png just gotta keep praciticing

I got a question for all you drag racers.



Last time I went to the drags at Cecil Co. , I had the car sideways quite a bit. More than when I'm on the street. Then I strated to think about how I did my burnout in the waterbox. Do you guys drive through the box or go around it and back into it? I think I was pulling water out on my front tires and leaving wet tracks for the rears to run in (No one told me how to do it.). It just now dawned on me that this may have been my problem. Am I right?

HMM. Sounds logical. Ive never used the water box, went around and did a gay burn out. But, Ive never seen or noticed anyone going around and backing up to the water box.

Ya know...I never thought of that. That's a really logical question. I always went through it. Its a waste on street tires though...it won't "gum" up a street tire..the compound is too hard. It only helps on drag radials and a few Z rated tires.



Vosko..you launched at 7K+..are you mad? LOL! I launched at 5K in my NA...my best RT has been .65 which was my first time ever...go figure.

that's not your problem. your not doing a big enough burnout. my bridgestone re92's will guy SOFT and grip hard after i do a nice long burnout to heat them up. makes a WORLD of difference.

ask anyone that went to the track with me, turborotor, silver93tt. my RE92's were gummy after doing the burnouts it was GREAT. made a huge diffence. i always launch at 7000 sometimes 8000 . the higher i launch the better my 60 ft gets and the faster my time gets. i haven't broken anything yet soooo. i'll keep on doing it https://www.nopistons.com/forums/pub...IR#>/smile.png

I have trouble doing a good burnout and keeping the car in one place. Since the pedals are so close and set up for heel-toe, I find it difficult to get my size 13's to power brake the car. I can bo a burn out by just letting the clutch out semi hard at 2500rpm and flooring it. The last time at Cecil, I dropped the clutch and the damn thing went right to 8000 in a hearbeat, so I shifted into 2nd, went to 8000 again but the car started to go real sidways (track workers started to move https://www.nopistons.com/forums/pub...IR ) The car only has an 80" wheelbase, so it makes it tuff to keep straight. Anyone do their burnouts in 2nd?



I even dropped my air down to 15psi, but it just made it real squirrely. I'm running Kumho V700's. I hope to have some new treads for Atco https://www.nopistons.com/forums/pub...IR#>/smile.png Anyone ever try the traction goop they sell to make your tires sticky?



Vosko - have you ever taken tire temps after your burnout?

when i do burnouts i heel toe you really need hold down the brake a good amount then punch the gas to get the tires going and keep the car still my open diff will spin both tires. i don't have a temp gauge for the tires but they get warm if i was guessing about 70-75 degrees after doing a few burnouts. they get to the point where they grab so hard they won't let me do anymore burnouts that is the point where i don't do anymore.

So do you burnout in 1st or 2nd gear? I could do it in 2nd if you think it would help. Kumho's work best around 190-210*F, so I would bet you are a little hotter then you think. If I make it to Atco, I'll bring the temp gun.

Ohh - I just had a great idea! I can reset my brake bias valve to get rid of most of my rear brakes for the burn out https://www.nopistons.com/forums/pub...IR#>/smile.png Then crank it back down for the run. You can see it in the pic while I was building the car. It is just below the shifter (which is now 5"shorter https://www.nopistons.com/forums/pub...IR )

i do burnouts in first gear and just hold rpms around 7000. a temp gun would be cool https://www.nopistons.com/forums/pub...IR#>/smile.png i have no idea what the temps were just guessing on when i touched them https://www.nopistons.com/forums/pub...DIR#>/wink.png man that thing looks cool nice work :thumbsup:

Vosko - It's a shame that they won't let you take passengers on the 1/4 mile like they do for Solo II (auto-X). I've got a matching passengers seat and harness https://www.nopistons.com/forums/pub...#>/biggrin.png . If this Atco thing pans out, I'll probably stay the weekend up there and hope to go cruising around in the beast. Oh, wait. I hate NO LEFT TURNS!!!! https://www.nopistons.com/forums/pub...IR#>/devil.gif

i would love to see your car run. i think it would be cool to have a passenger down the 1/4 see him go OH MY GOD WE ARE GONNA DIE!!! https://www.nopistons.com/forums/pub...IR#>/devil.gif

I need to mount a fake steering wheel and brake pedal. Most people I take out on the auto-x course start to pump the imaginary pedal and move there hands like they are trying to steer https://www.nopistons.com/forums/pub...IR#>/smile.png The best part is that there is nothing to grab onto on the passengers side. You have to trust the 5pt. harness, and most people don't https://www.nopistons.com/forums/pub...#>/biggrin.png



I just laugh and go faster. My wife hurt her neck last time she rode with me. Lets just say the brakes work well...

They let people ride here at the drag strip. :tounge:

yeah. you are just what i like to see driving a rotary vehicle https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

best r/t =.51

worst r/t = .8x I forget

first r/t = .64

just go as the last yellow comes on...

They let you have passengers at MIR..but only if your car is 13 or slower I believe...any faster..and its your own life, lol.

Hey, I didn't know that. Bring your own arm restraints....

About the response times,,, I let go of the clutch a milli second after I see the last yellow light goes on. This has worked for me, my best response time was .309 However, my best quarter mile time has been a 16.7 in the fall. I'll be back in 2 or 3 weeks though, and we'll see my time after the mods I've done. Oh, by the way I have a 1980 gs.

I've just been informed that I couldn't have gotten a 3.09 response time. I have the slips at home, I will check them out tonight. :dontgetit:

I'm not sure how burning out with street tires helps your traction but more power to you. From my own experience, I've always gotten actually better 60' times by avoiding the burnout box when racing on street tires. Slicks are a whole different story. You may want to try just a small burnout (to get the stones and crap off) and launch at around 5K with some clutch slip to limit your wheel spin....you need to feel the tires hooking up......just offering my experience.......... and keep in mind that reaction time has nothing to do with you actual ET (so don't rush it if your trying for a good ET). Your R/T is important in winning a race and critical in bracket racing but the timer doesn't start until you cross the line.
