Drag Racing

[Brenton 86]

Anyone into drag racing there ae86??

Went to my first test n tune drag racing event last night and had a ball!

What times have people got? I was pretty stoked with 12.965

[Rice86]

Car modification specs? whats the power at the wheels? etc etc

[Adsie]

Taken mine down a few times, best I ever got was a 15 flat.

What times have people got? I was pretty stoked with 12.965

fuck 12.9, thats pretty solid! what was the trap speed you got mate?

60 footers not bad, that can be worked on, but 12.9 @110 (175km/h) seems like its got some good top end! with that trap speed and average 60ft (1.8-1.9) shoould clock about 12.5 @ 110-115 (175-185kph) easily enough.
maybe try some less crap tyres or borrow some semi slicks of someone and see how it goes.
also maybe drop a couple of PSI out of the tyre (around 20-25psi is usually pretty good) and set you rear shocks to the softest setting.

[Gunner]

^^^On the money xero.

Don't be scared of using a retread either, best budget drag tyre you can get, just don't cook them, when doing your burnout (they will get greasy). Going back a few years now, I ran a 205/60/14 retread on the back of a vl with a little less power than you are making and ran 12.6@112 consistantly. Also if you want to step it up look into drag specific shocks for when you go out to the drags, like a 90/10, provide awesome squat, will make them bum sit nice and flat on the launch. Suspension is good for alot of time on the strip, so worth looking into if you want to go quicker.

[xero]

more of just an FYI than anything, but was it a just a weekly meet (like we have a WSID every wednesday) or a proper group 1/2/3/4/5 round?
the reason i ask is that usually when its a weekly street car meet they will set the track more for slip than grip. so a that normally launches at say 4000rpm on at points round will grip (due to better track prep) most likely will spin the wheels this time. they track officals do tis so there is less breakages and oil downs and can keep the cars moving through qiuckly.

as gunner said, a few minor things can get you some big gains. but if you dont want to go to much trouble just do the basics (soft shocks, tyre pressure) and just work on your launches.

[LittleRedSpirit]

Been out to test and tune 3 times now. In my NA stock 20v silvertop ae71 my best was 15.511 at 90mph or so.

I enjoy walking around and picking races with people driving similarly matched cars. Its a shitload of fun. Its great on those iffy nights with a few clouds in the sky because nobody shows up. Last time I went (with Timbo) we were literally driving straight to the front of the cue and racing over and over, and some dude brought his sexy girlfriend and since I was racing and chatting with them in between runs she decided to give me full driveway timeslip service, which takes away the one annoying thing, sifting through 200 slips to find yours.

Im keen to go again and see how my motor is performing at the mid to top rpm range, now that I have done some further tuning.

[Gunner]

what are you 60ft-ing at?

With a trap speed of 90mph, you should be able to crack a 14 as it is. Don't be scared of wheelspin, learn to use it. (not saying ou are, but dont be haha)

[xero]

60ftrs are the key to drag racing, got that right and its worth up half a sec at the other end.

and no wheel spin is not a bad thing, you dont break shit either...

[Brenton 86]

I was just at a wednesday test n tune. It was deserted, got 13 runs including breaks to cool the slipping clutch.

Its addictive tho! I'm throwing a new clutch in and re-tuning back to 280rwhp.

With your tips and some practise hopefully can get into the low 12's or dare say it the 11's.

[LittleRedSpirit]

I intend to break into the 14s before getting over it with this vehicle, Im waiting for winter before I get too concerned. I have dropped time each time Ive gone out and progressed each time, almost in a linear fashion each run. My best reaction time was 0.06 seconds. I was real happy with that.

I haven't yet tried any real weight reduction or used the little trick I've been told about to get an amazing 60 footer.

I'm 60 footing around 2.25 seconds.

[Gunner]

Could be going a bit quicker than a 15.5 with a 2.25 60ft.

Going through the traps in 4th? if you are shifting just prior to finishing the run, you may be loosing a fair bit of time. I'm not sure what gearing you are running so I can't give any real help there, but if you are shifting on the line or just prior, hold the gear prior, loosing half a second of drive on a shift at the line can cost a bit of time.

Also, although it is fun trying to pull a good reaction time, focus more on launching the car, rather than when you want it to leave the line. after all at a test and tune, a reaction time is worth exactly nothing, its the ET you want, and your reaction time is never going to affect, so spend that second or two in staging making sure it leaves the line right.

Not meaning to sound like a know all or trying to tell you how to run your car, just trying to offer my knowledge :))

[LittleRedSpirit]

Yeah you're just kind of answering a bunch of questions I never even asked, since its all more or less stuff I know or have been told before and continue to work on, but go nuts, whatever makes you happy.

I've got lots of things to try and I'm doing experiments as I go.

The best 60 footer was under 2.2 but it wasn't the quickest et or trap speed. I've tried hitting the traps in 4th but it was quicker to bounce 3rd off the limiter a moment at the end (4.3:1). I reckon the most important thing is that the car can pitch back and plant the diff as it goes off the line, eliminating as much wheelspin as possible and forcing it to lurch forwards. Secondly, quick shifts with a lot of revs behind it.

[LittleRedSpirit]

PS, I enjoy getting good reaction times, I go there to race people and test my car, I'm not some serious drag racer, and it doesnt count on test and tune of course, but If i know I just have to add 6 one hundredths to my time to make it official, Im happy. I am competitive and as such want to have perfect reactions each time if possible, more so to try and beat whoever I'm racing at that time.

[Gunner]

Not a case of answering questions you haven't asked or you already know, I'm curious as to what is holding it out of the 14sec bracket. And it may help the other fella too.

But you are correct with planting the diff (squat) as I said before suspension is where it is at. But the front end, and how it lifts plays a big part so don't just concentrate on the rear end.

One other little trick to keep in mind is not going deep into stage, that way you aren't loosing time when the car squating/lifting the front, as most of it has happened in the couple hundreths of a second before you actually trip the clock.

If you can't tell I do love drag racing haha.

[Gunner]

Heres how my reactions are going.

[Gunner]

Good shit man, looks like you got it down pat.

[ae71]

noted both cars had front missmatched panels.. what are the chances.

btw i was just trying to stir, didnt get a nibble.


my old man was into this stuff. had a old XB ex-bathurst falcon that had been converted to a drag car (owned by a speed shop!) full tubs, big N/a ford V8 on methanol, shoot, was a fairly serious bit of gear. used to run low 10's

[LittleRedSpirit]

Yeah I know you were just teasing but I try not to feed the trolls.

I used to write drag racing off hard until i actually did it, its a lot of fun, all the people who do it are up for a chat and a bit of tongue in cheek competitive slander, its a real laugh. Its something everyone should do at least once in each car they own.

I think those 2 vids show my 2 best reactions ever, 0.99 against Timbo, and 0.06 against the commodore. I broke one once that night but only by 0.1 or so. Got a bit excited.

[timbo]

oh man i bogged that one down well and good haha

[LittleRedSpirit]

Yeah but it was your first visit, you did fantastic for a first visit.

[DX20VT]

I went back to the drags with my car last week, first time back there for 4 or 5 years.

Reaction .612
60 foot 2.049
660 7.679
1320 11.548
mph 128.4

That was best time of the day, best MPH for the day was 129.9.

Need drag type tyres to go any better.

[cri_ag]

12.4 @ 117mph in my sprinter. cheap shit tyres, heaps of wheel spin. need to go back with better rubber for hopefully an 11sec pass.

Would you believe me if I tpold you with the right tyre/suspension set up. you could reel of a low 10sec, maybe even a 9?

[johl]

brenton was that you i was talking to at the last servo before qr a few wednesdays ago? kouki trueno coupe with sr?

fuck me 129mph! that s fairly moving along!

gunner, possibly in a perfect world might get to a high 9, but repeatable mid 10's he'd piss it in!

[Gunner]

VHT, atleast 26x8s and some proper strip suspension, 9's would be doable, hard, but doable.

[xero]

oh yeah definately, but would it be worth going to all that effort for maybe a single 9sec run, where as you could run mids 10's all day long?

[Gunner]

no not really, but he would be one of thevery 9 sec 86s world wide haha

[xero]

what about C&Y sports with the 2J/RB26 or the peurto rican rotary AE86?

[Gunner]

yeah, but they are hardcore drag cars, 3/4 chassis in the rotor, not sure on the specs for the other cars though.

I must admit this thread has started that itch, I would love to go buy some drag worthy, and thrash the ass out of it, oh how I miss my vl haha.

[xero]

C&Y are full chassis.

but i know what you mean, i keep dreaming of a full sized chrysler E-body with a TT 426 or a 500ci TT wedge motor...

[Brenton 86]

brenton was that you i was talking to at the last servo before qr a few wednesdays ago? kouki trueno coupe with sr?

yeah mate! was on the way out there.

[PRIMRK]

My dad used to drag in his FJ holden, i think he was sitting round the 14 sec time, bare in mind this is 40 years ago now.

I think once my track car is done ill have to pop down to have a go at drags at least once or twice, do more torques help at the strip? or is it in top end power?

[Gunner]

you need the torque to get to half track, and power to drive it the rest of the way.

[LittleRedSpirit]

Hey guys.

Test and tune is on again soon at Willowbank.

Ill be going out again the next Wednesday, 9th of March. Im going with a mate who has a datto 1600 with a ca18det. I just did some dyno tuning so Im keen to test it out.

Be nice if there were more NA twin cam cars there as Timbo is off the road and he usually comes and races me.

[brutus]

went down to Perth Motorplex on Wed night and this is my slip:


Time slip says:
R/T.....0.364
60'.....2.175
330....5.962
1/8....8.962
K/mH..132.78
1000..11.465
1/4....13.572
K/mH..173.03

Mine is an Ae71 with a Sr20det. Clutch is starting to slip and a bit of wheelspin at the start. This was also my first time on the track.

[LittleRedSpirit]

Just a reminder, Willowbank raceway tonight people.

$40 entry.

Long sleeves and pants, covered shoes and an adr helmet required.

Im going, so is my mate with his CA18det 1600. I think maybe a few others too.

Just hope it doesnt rain!

shoud be able to dip into the 12's, as mentioned earlier drop a couple of PSI out of your tyres, work on your launch and 60ft and you'll punching mid to high 12's easily.

[Brenton 86]

Damn missed your post littlered..

Would of come, might head out next wed's

[Gunner]

Good stuff man, what times did you run?

Should stick a wet 50 shot of gas up its ass, just run a fat fuel jet to keep it away from det. Could run more, but I'm not going to tell you to do that :))

[LittleRedSpirit]

Basically exact same times as last time, but with a better 60 footer. I have just had a retune and it makes a lot more midrange power but it peaks earlier, so although the 60 footer is 2.1 flat now Im still pulling the same ETs. That said it was a lot hotter, 22C and 80% humidity.

The guy in the GTS 325 got a bit of a fright! makes me lol.

[Gunner]

see you need gas, you need more top end haha. Seriously though, you could easily drop .5 of your time with just a wet 50 shot. Gas is really good to help make torque, so it is well suited to little 4 bangas. That said if you do go that path ($800 for a simple kit) I know you probably wont, but if you do, just make sure you do some research on how to use it right, can do some serious damage if you don't.

[LittleRedSpirit]

Ive considered it but Im not too fussed. This car is no fuss daily driver style. its not going to modified in anyway to really make a it a race car as such.

[Gunner]

but thats why gas is a good option, because its only there when you want it to be.

[LittleRedSpirit]

Yes but simplicity is the key, if I can do more with the hardware I currently have installed Id like to do so. Even if it takes time.

[LittleRedSpirit]

Run - 1 - 2 - 3 - 4 - 5
60' -2.203-2.157-2.165-2.104-2.112
1/8 -10.10-9.994-10.03-9.943-9.970
1/4 -15.77-15.62-15.64-15.58-15.62
MPH -85.86-85.53-86.14-86.30-86.09

Here are the 5 runs, was pretty happy with the 60 footers compared to last time. I never got below 2.2 before really.

Im pretty sure my fastest run was against the GTS 325. Run 4. It wierdly was the run after the oil down. I guess they had just resprayed the track with PJs.

[Gunner]

Atleast you guys get a prepped track, our $55 wednesday night meets are an ice skating rink, and as a consequence, iff you go quicker than 9.0 you cant run, its bullshit. But there is monthly prepped runs, but not bloody cheap.

You are pretty consistant dude, if there is a bracket you can slot into you should compete, puts a whole nother spin on things haha. Also a set of M/T et streets would be good, and they'd last a lifetime on your car.

[xero]

i concur, slot into a dial your own bracket and wind up some of the big boys :lol:

[LittleRedSpirit]

Hi guys.

Just for the Brissy locals, Im going to the next test and tune this wednesday night. 20/7/11.

I plan to data log a couple of runs and make a few changes in between to try and go quicker, plus I havent been back since i set up the 4.5:1 rear end, it was 4.3:1 last time I went there.

If you can come out, its a lot of fun.

[s14seriesII]

11.75 et on old drift tyres.. turbo was buggered and rather hot and humid day (even my fuel was boiling hot)..
should be heaps better next time..

had a quick search of your posts... but just quickly what set up to get the times you mentioned?

[LittleRedSpirit]

http://www.youtube.com/user/MJBOGAN

Just the stock 20v 2way lsd trd and t50. Adaptronic, 1zz cops and 4.5:1 final drive. Street tyre and pressures. 205/50 r15.

[slydar]

ok nice. thats a great result then :)

[lappy]

Do you run a T-series? what did u get the 4.5:1 final drive from

sorry for the hijack

[LittleRedSpirit]

T series, bought gears from japan.

[LittleRedSpirit]

Hello again. Im off to the drags again tonight, so far we have a turbo 318I 2 door coming, and a springter (timbos panda) and myself in my AE71. Another guy I know is bringing a Nimbus to race, should be hilarious!

[LittleRedSpirit]

So the beamer didnt make it but Timbo didand he did some PB times now that he has been rebuilt.

Also got to race another 71 (Ash was his name, Trevs old car from rollaclub), and there was a ke70 sedan that looked to have a carbed v8 in it doing some OK times.

Had a run at the drags a few weeks ago, ae86, 4agte, gt2871rs turbo, w58.

ran 11.7 @ 119mph, got kicked out.

[xero]

how can you get kicked out for that??
unless you did a half track burnout or something else stupid they generally give not much fark...

[Gunner]

Need an andra license when you run an 11

[cri_ag]

yep, went 11.9 they warned me and said to turn the boost down. lined up, turned the boost up, ran 11.7, day was over. Need super street andra licence. 26206
passenger side in the air!

[xero]

shit! yeah forgot about that... i kept thinking you hadnt run a 10, so "the fuck is going on" but you need a cage if you run 10.99 and the licence to if you run an 11.

usually they give you the option of buy the licence at the meet if you run something like that, or have they changed that too?

[Gunner]

Nah they will allow you to buy the license and keep racing.

[ke_70]

lol turn the boost up haha

They gave me the option when i ran 11.9, the option was not given after i went under 12.0 a second time. it was day over.
