0-400m tech for ITR owner

[edw-R]

I find a good post for 0-400m tech for ITR owner. It's a little bit long. Hope can share with you.

Part 1.


All times mentioned are in regards to racing on true street tires.

1. What does a bone stock ITR run?

A normal ITR in ideal conditions around sea level Generally traps in the 94-96mph range. The ET is going to be up to track condition and the driver. With a good driver and track under the same conditions a stock R is capable of SOLID mid 14's, easily dipping into the lower 14's on the best runs with an experienced driver.

If your car is trapping in that range and it isn't running the times you want it's either the track or the driver, sorry but the car is running just fine.

For your first time at the track be content if your R breaks into the high 14's, don't worry, its not the end of the world. My first time at the track I had to struggle for a a 14.7@93.5mph


2. I have a stock R and want to pull mizzad fast times to impress chicks, what do I do?

Buy a Z28. Seriously, the key is PRACTICE, PRACTICE, and more PRACTICE. Do not substitute mods for driving skill.

A: Learn to read a time slip, as in the whole thing. You don't know how many guys I've met, that are at the track regularly, that still don't know what it means when I say "yeah, but what did you trap, or what was your 60'?", all they are concerned with are the numbers at the end, not the ones in between which are far more important. Sit down and break apart a good and an almost as good run, see the differences in time and speed at each point, try to think why the car would be doing what it is at the point where things don't match up. Your own noggin and that little slip can tell you alot more than what Joe Bob thinks you should do on the next run.

B: Pull a good 60' THAT IS IN THE POWER BAND! If you can't do this then a fast time isn't happening. 3rd gear VTEC, mad fast shifting skillz, lucky underwear, or a picture of your girlfriend covering the tach doesn't make up for a bad launch.

LAUNCH IT HIGH AND MODULATE THE CLUTCH AND GAS. This is how I've pulled my best 60' and 1/4mi times. My best launches were around 6-7000rpms ON TRUE STREET TIRES. Those that say that is too high for street tires just haven't practiced enough, or don't know what they are talking about. This is why I say practice is the key. I hold my revs at the determined rpm and bring the clutch part way up, to the point that I know it is going to start engaging. When I launch I do not apply more throttle, the throttle foot stays the same, if not releases some, as I smoothly but still quickly engage the clutch, when I feel the car will have traction I peg it the floor. The goal is to gain as much traction off the line as possible but to keep the car above 6,000rpms in the process.

Dependant on track conditions this will not always be possible, I know it wasn't for me. This you just have to learn. Start from a lower rpm and work your way up.

Now some of you are saying "but can't I pull good 60' without having to launch so high?". Yes I use to do it all day long, but then guess what, that makes our high strung cars have to pull through the dead spot of the power band, which is just wasted slow "hurry up and get to VTEC you torque less POS" yelling time. http://images.honda-tech.com/set1/smile/emwink.gif

Example: Some guy hooks a 2.2 60' from 3,000rpms, another does it from 6,000rpms...... guess who wins. http://images.honda-tech.com/set1/smile/emwink.gif

Oh and for all of you wondering I have pulled 2.0 and a bunch of 2.1 60' times on true street tires (not drag radials) with such methods. That should be enough evidence that it works.

C: Learn to shift fast. No not how you think you've been shifting. You banging the shifter at lighting speed means diddly squat. A four year old spaz power ranger wannabe could out shift us all if that was the requirement.

Fast shifting is all in FAST FEET COORDINATION. You can press the clutch in, then 3 days later snatch the shift lever at Jedi speed into second gear (thinking you're shifting fast), go to sleep, eat, whatever, then slam your foot off the clutch. Your hand speed was fast. The actual shift took three days, a nap, and a meal.

Right now sitting at the computer fire off the fastest front snap kick you can muster with your left leg. None of that pressing down letting off crap, a nice sharp kick, fast as you can there and back. Congrats, you just did a really fast shift. Now time that with your Jedi hands, learn that you can actually miss gears now because you really weren't shifting that fast before and subtract a touch from your ET. Don't get too happy though your 60' is FAR more important

[edw-R]

PART 2:
3. It's my first time at the track. I keep peeing my pants, crying uncontrollably, and for some reason I seem to be driving like crap, what gives?

Yeah I thought it was going to be a piece of cake too. Then this crowd of people appeared, 600hp drag cars started showing up everywhere, this announcer started talking, and this blasted flashing light starting thing apparently cast a spell which erased all knowledge of my ability to drive my car. Lights flash, brain goes dead, right foot down, left foot up, did I shift back there?, what did I launch at?, did I even launch?, have I even ran my car yet?, what's a car?

It happens, called being nervous and distracted. The first thing I learned is to FORGET THE STINKING LIGHT AND THE GUY BESIDE YOU, until you get the hang of it. Remember your reaction time HAS NO EFFECT ON YOUR ET. You can sit at the light for a week if you want and still pull the best run of the night.

Don't worry about reaction times your first night. Just focus on a good launch and not missing shifts.

Did you get paired up with John Force this run? That is one of the most annoying things ever. Let the 600hp open header Camaro launch ahead of you, it makes sure you don't get creamed, and you get to focus on your run once he is done sliding around the track.

Remember it takes practice. Get the jitters out then start having some real fun.

4. Tire stuff.

Run high pressure in the back to keep it from squatting/unloading front. Lower the front pressure just enough to were you are getting good traction. Don't drop it down to 3psi or something. Remember you are on street tires. The lower the pressure the more the rolling resistance. Find the proper balance. A stiffer sidewall tire will generally be run at lower pressure for obvious reasons. Check them right before runs for consistency, pressure can change throughout the night.

Tip: For us without compressors fill them all the way up at a gas station and work you way down during the night. Don't bleed them low from the beginning because if it's too low you are stuck with it all night.

I generally ran around 20-22psi.

DO A DRY BURNOUT. Notice I said DRY, not a wet. Go in the water box and you might as well make a run on ice with street tires. Some people will argue about this, when they pull better 60' times than me I'll listen. Driving between runs you pick up dirt and other crap, doing a dry burnout will clean them off simple as that, and depending on the street tire a little heat might actually help. I usually pull the ebrake, but not necessary.

5. Do your normal maintenance, such as spark plugs more frequent if you want the best times. Mine always loved a fresh set of plugs. Little story, I was at the track one night car was "only" trapping 96mph, I knew something was up, check the plugs, they were fouled out. I ran to the store and picked up a new set, installed them in the parking lot, and my trap speeds bumped back up to 99mph I kid you not. A well running car means everything.


6. What's some simple stuff I can do?

Easy. Take out your seats and spare tire, remove the power steering belt, and unhook the exhaust. All free and they worked for me well.


7. Ok I've got everything down, launching good, and taking care of the car. What should I expect?

We are now saying you have a well running R, you know it by heart, and can launch/shift the fool out if it. You are also blessed with a good track and location.

Bone stock- 14.2-14.4
Free mods-13.9-14.2 (weight reduction)
Bolt-ons-13.6-13.9 (depending on weight)


Some personal times of note.

14.03@99.35mph- AEM CAI, free mods listed. This was before I had ever landed a 2.1 60' as well, but was due to the fact that I launched in the power band. It does
make a difference.

14.3@97mph- AEM, full interior, 115lb passenger.

14.3@96mph- Full interior, AEM CAI, JDM DC header modified to fit stock exhaust, 200lb passenger.

14.4@95 in 80 degree heat with extremely high humidity. Just AEM CAI and no exhaust.

13.8@98mph with a 2.0 60'. AEM CAI, JDM DC, running on 22lb CRV rims.

and the big 13.7@100.42mph. Same mods as the 13.8 listed above just a better night.

End notes: These times are not from some mizzad driving gift on my part. It came from simple practice and figuring out what works and what doesn't.

Who's it by?

[vtir22]

:confused: :confused: :confused:

If this guy is so serious about drag racing, he's in the wrong car.

[Xenon]

That first post sounds like from the USA.
For some reason, they always get AMAZING quartermile times in stock cars...
hmmmm

[bumography]

Right now sitting at the computer fire off the fastest front snap kick you can muster with your left leg.
Great.. i almost knocked the table down..

[Savant]

Great.. i almost knocked the table down..lol


If this guy is so serious about drag racing, he's in the wrong car.maybe he likes the type r and wants it to go fast

short people can play basketball and enjoy it

Can you do it with your stock car??
Type R isn't only give you good cornering and also give you good acceleration.
When you are in traffic light or start on the track, you also need good starting method. Something like the post. Need practice, practice and more practice.
Sorry. Maybe i am little bit rude. But i am serious. Tyre R is the best FF with 1.8L engine.:)

[Mugen boy]

NAH HONDA 1.8L TURBO.......GOES OFF, but i would like a type R

[vtir22]

...short people can play basketball and enjoy it:confused: You don't choose to be short! you're born with it. But you choose which car you buy. I'm just saying he seems to put a lot of emphisis on the drag strip... The R was and is always about having 'the' optimised package for the track - one with corners :D.

Sorry. Maybe i am little bit rude. But i am serious. Tyre R is the best FF with 1.8L engine.:)Dude you don't need to convince me, I own one. You're preaching to the converted. I'm just saying this person spends so much time getting tenths out of his quarter mile seems is kinda pointless to me. If you're serious about drag racing that you do it so much you might as well get a RWD car with a turbo or a big motor. The laws of physics state that acceleration is the forte for RWD/AWD cars. Accelerate -> weight shifts back (front gets light) -> rear tyres get even more traction = better launch... Work that out with FF.

Can I do it in my car? I don't know, never been to a drag strip and never will with my car. Why would I want to wear out my clutch and gearbox gaining tenths off my quarter mile? Traffic light sprint... so what if you win? so what if you lose? I can get much better kicks and enjoyment out of my car in less destructive ways and really enjoy the car the way it was designed to be enjoyed. :)

I just find FF drag racing pointless. Just as I do turbos on a VTEC motor. To each their own.

[Civic Type R]

Id like to see a stock ITR get those times !!!

[edw-R]

Hi, vtir22. You seem very angry. I agree with you. Most of integra owner usually concerns the handling. Not concern with drag racing.
In my point, we are not a drag racer, but we still need to learn how to control our car in any situations. I also love to race on the track. Hope you can understand!!

[Javed]

If the fellow wants to drag his car that is his own perogative. Shit, why tell somebody to get a turbo car or whatever. Maybe this guy likes the challenge of getting a NA type R down the 1/4 the quickest he can. Maybe he likes cruising around in the R than any other car? Sheesh!

[tinkerbell]

Id like to see a stock ITR get those times !!!
go to a drag stip and watch someone who can drive run.

14.7 is easy for stock ITR on a proper strip...

(anyone remeber what Charles Kha ran in his yellow ITR at Drag Combat in Feb? i think it was a 14.6? it was pretty stock...)

sounds like the guy doing high 13's has had LOADS of practice.

everytime i ran at EC or WSID i got better and better.

i reckon my LS was capable of mid 13's but only managed 13.7's due to me not being able to crack a sub 2.0 60ft

practice is the key.

[Civic Type R]

tru dat !
I can go out and buy a piece of shit Nissan silvia for $5000 or a VL commie and get 13's all day.
Us Honda drivers will kick their asses on the track and i have proven that with a 400HP Supra and a 400HP R32 GTR - where i came within 2 seconds on a full open track. I beat the supra by a few seconds tho. Not bad considering this GTR pulled a 12.2 1/4mile ...

[bluebird]

I agree with almost all the stuff posted about how to race at the strip, and it was exactly what I did (although I figured it out from my last car, so it wasn't brain science).

However, in my VTiR, the main problem I find is stock clutches handling 6000rpm launches... hence my 2.3 60FT times (although an LSD would be nice too!). Not sure if ITRs have stronger clutches from factory?

that tells me that you are a better driver than the blokes you were playing with more than anything :)

now, if you yourself managed to beat your own gt-r time in a civic i'd really dip 'me lid to the civic, but realistically, unless you run out of nutsack, it's not going to happen. ;)

[vtir22]

edw-R: no not angry at all, just saying the R is not a drag car. A series 1 RX7 with a worked rotary is (all under 20k)! Just seems a waste of a great car to concentrate on 1/4 mile :).

They have stronger "springs" to give more grip than Vti-R but not much i think....

[Sp3rMz]

Dam it was too long to read. Just wanted to add quick comments. According to Honda, the dc2r was released with the results of high 14s as a 1/4 time. Yet reading alot of other magazines they claim dc2r can only pull 15s. In the end i believe Hondas results, thing is Honda would have like pro drivers to push the car to its limit and spend their life time runnin 1/4. Shrugs. Just take your car down the 1/4 and do time test your self. Just keep on practisin and see if you can break 14 seconds.

[tinkerbell]

no you cant.

[Civic Type R]

or until the RB or SR block overheats, blows a coil pack, or throws a turbo bearing your correct ;)

[tinkerbell]

a serious comment overheard from a nissan driver at the 'creek in summer 2002...

"geez, lucky i bought my spare coils!"

[euGeR]

Dude, should really include the link - respecting the guy who wrote it (from honda-tech by the way)

but what's more satisfying than gaining tenths in the same car, track or drag? means the driver getting better yeah? :)

[My-B18c]

damn i CBF reading it!! but true that wrong car your in!! so serz about drag racing! you should ask croydon racing 4 a spot 2 drive 4 one off their cars an get sponserd

[tinkerbell]

but what's more satisfying than gaining tenths in the same car, track or drag? means the driver getting better yeah? :)
i found the drag strip to be more 'fun' when not racing, especially at the big competitions and other competitiors were pretty freindly regardless of their vehicle make...

and circut racing is more serious and there is a degree of eliteism depending on which event you are at...

but i love both, and get a different type of satisfaction from either...

it is also a challenge to build a race car that is both good on circut/hillclimbs and drags :D

but these comments are sooo off topic ill shut up now.

[edw-R]

Anyone can start at 6000rpm?? When i started at 6000rpm, spin all the way. I think i need to practice, practice and more practice.

[tinkerbell]

that simply means you are not slipping the clutch enough dude...

[type one]

hahaha vtir22 is an angry boy...but a drag strip is not a situation you find yourself on rarely unless u put yourself there... i own an R as well and believe me its much more fun around the corners than down a straight line... having said that i could run flat 14's on street tyres - never stripped but raced against turbo counterparts who easily ran low 14's and wooped em.

you get bored going fast in a straight line after a while...having said that i used to enjoy taking Nisholdfords down occasionally.

[connorling]

i think american always have a lower 1/4 mile time than us, my b18c EG can only clock 14.74 with street tyre before tune.
and my car beat stock dc2R, some says the gear ratio, but he is saying around high 13sec, i really dont know how it works!!!

[hisoka]

thanks for posting it up

[midnightdood]

Wow.. that a decent time. What was the trap speed ?
Was the run with the stock dc2r from a standing or rolling start ?

the post say someone can do high 13sec in dc2r stock, i really cant see that happening.

despite my efford, i did 14.70sec, improve 0.4 sec.
my reaction time is 0.009sec, 60ft: 2.4sec

[RR-04-RR]

A stock DC2R cant do high 13s

A DC2R with I/H/E can

You can easily run low 14s with a B18c in an EG

whats your technique?
I ran a 14.6 with a stock DC2R with only intake

[aaronng]

You need more practice with the launch. On my first time on 1/4 mile, I got 2.4 second 60' time on my very first virgin run by launching at 2000rpm in a fat heavy Euro.

[SHI-FTY]

check this out guys its the vtec.net vid with the silvia n typeR racing both stock not to change topic but its showing the stock jdm dc2r on 1/4mile im not sayin you cant do anybetter than the time achieved in this but its interesting, top post tho found it very interesting to read but still cant believe the times he got

http://www.youtube.com/watch?v=KHI3fYqvYGY

[Nepolian]

This must be one of the oldest back from the dead threads.....12/04 to 05/09

I've seen JDM headered, cat back and intake do 14.1's.

[Zilli]

ive done 14.3 with mine, all it has is an intake, light fly and hd clutch... from an engine perspective... bald rt215 tyres and coilovers....

[ewendc2r]

I can understand why people want to drag race their cars -- I personally have never had the urge to see how fast I can get a car down 400m of tarmac. This impacted massively on my purchase. The only time I give it a bit is when someone asks me to or moreso, I want to see their car go hard (I don't care if I lose, get laughed at.. I still got to see that <insert crazy fast car> go bananas down the street).

P.s. to the guy who commented on the r32 400hp beating the honda, I'm a realist and generally I would agree. When I have gone out to the track and beaten some 500hp HSV R8, or lapped equally with an M3 I have generally just thought, what are they doing here? Maybe they aren't prepared to crash their car, maybe they've had little track experience. But at the end of the day, their smile was just as big as mine when we got out of our respective cars at the end of a session.. Mine was was only bigger when the lap times came out :P

The CRX at QR (You know the one) cracked a 57s lap on the sprint circuit, which is out of control. I think its a lap record for registered vehicles? Well and truly faster than any GTR I've seen on the track and as quick as GT3 Race Cars.. V8 Supercars only do a little quicker again, so there is potential for a Honda to to be seriously quick but it takes an ex-F3000 driver, a 700kg car and big balls.. (Respect man).

Keeping it on topic -- Has anyone noticed a difference from putting pizza cutters on the back? (i.e. similar to space saver spare tyres?)

I might go out to Willowbank one day, but if I had the choice (due to time/money constraints) I'd go to the circuit hands down each time..

keep it real.

[4age8u]

no you cant.

get a vl turbo for 3k then 2k on mods 13 allday easy as that..but hey its a vl :p

[denrie]

When YBOOST had his B18C7 in his DC2R before his K20, he done 13.9 with just intake and catback I think.

[Red_EG4]

get a vl turbo for 3k then 2k on mods 13 allday easy as that..but hey its a vl :p

where are these 3K VL turbo's?
do want.

[jords]

where are these 3K VL turbo's?
do want.

There all in Auburn.

[ninzee]

LAUNCH IT HIGH AND MODULATE THE CLUTCH AND GAS.

GAS=AMERICAN lol
