View Full Version : 115kw DC2 running low 15's

Hi All,

Firstly I don't think my car is anything special. I know it's not a RB26DETT or v8 machine, but on my DC2 I've done the following mods and enjoy modding it, driving it and now I'm getting into the tracks (circuit and 1/4 mile):

Mods are from a stock 95 Integra VTI-R:

Custom 2.25" cat back into xforce twin loop
5zigen headers w/ high flow cat
Injen intake
Toda Lightweight Flywheel
Exedy HD Organic Clutch
Hondata S200 tuned by James (BLKCRX)
King Superlows.


180,000K's on the motor. 20,000K's ago, it was tuned at 114kw on the Dyno by James.

Everything else is stock, including rims. I removed rear wheel/sub/amp before I did the run and dropped front tyres to 20psi.

I only got one run down the 1/4 mile and ran the following:
60ft: 2.346
MPH: 72.42
E.T: 15.215

Now, because it's my first run I expect say, .3-.4s added on. So lets assume, 15.0 flat. Is this car a 15s flat car with it's mods? I thought DC2 stocks run low 15's? I'm not asuming myself as an ITR owner etc or anything, but doesn't a stock ITR run roughly 14.3 (http://www.ozhonda.com/forum/showthread.php?t=72716), and thats with roughly 102-105fwkw. Surely I should be in the mid to high 14s at least with my mods?

Would my suspension cause such a bad time? The king springs are shocking. It sits low and looks good, but is really bouncy, I often hit bumpstops turning a normal corner and scrape on hard braking and corners.

I'm not claiming I'm a 13 sec machine or anything. Just looking for a bit of advice on my setup etc. I would love to touch 13.9.

Thanks!

have a read of this thread....remember...dc2r has more power than dc2 vtir...

and half a second difference is a lot....

you'll need to strip your car so its really light, look at the tyres your using etc

114 disney watts? No way a car with that much power would be only getting 72mph.

either you are a super bad driver or your tuner has fooled you with some dodgy dyno numbers.

on a side note... b16 EG's with around 105kwatw run mid to high 14's depending on driver with 90-95mph.

the 114kw is on a hub dyno.

Yeh, it doesnt adds up here...
115kw atw should definately be close to high 13s, low 14s.

m8 ive seen numbers from people who's first run on the strip was 16s or 17s then when they had practiced there car was running 14s.
so practice makes perfect
if you do a couple more runs and ur car aint running any better but ur reaction times are good
mayb get the car tuned n dynoed again
it would make sense that if ur car has the pwoer claimed then u'd b runnign a bit better, but dyno numbers can be a fair bit out of whack at times.u'd b hoping to pull some good numbers as ur car has a bit down to it so by no means is it a sloucher
good luck with it

What's with all the arrogant replies? I'm asking nicely what's the go. How about we grow up a bit kids. I'm stating the facts and asking nicely for advice.

Thanks. Yeah, honestly I didn't think my first run would be good. And I'm keen to go back.

No, Last time I checked the dyno graph (which when I get home I'll post a picture of) it said atw kw in 4th, but I'll confirm for you it's not disney watts

FYI All, the hondata install and tuning was done at Springwood by James during the Hondata Mass Group Buy at Advanced Performance Centre (APC) in Springwood. You're in Brisbane barefootbonzai, what's there dyno? Maybe you've had a car on it or can confirm it spits out cheap numbers.

Ironically, I remember reading your post here (http://www.ozhonda.com/forum/showpost.php?p=1300211&postcount=17) which said "why do people think a couple more runs are gonna cut a second off". So you're saying I'm a shit driver, which I accept based on it being my first run, but I won't cut a second off?


i reckon it's either a typo or he remmebered wrong, a leopard can run faster than that...

Attached is the timeslip. I have good memory, thanks.

Thanks. And I completely agree with you. But if you infer what barefootbonzai said in his other post, 1 second which he said couldn't be cut down even with practise, would bring me into the rough expected range. This is one of the reasons why I started this thread, instead of just heading out. Well, Brisbane is raining and will be for another week so I won't get a chance.


the 114kw is on a hub dyno.
Umm, no. Dyno graph is coming. And as said above, it was on the Hondata Group Buy a few months back, tuned on APC's Dynos by James. You seriously think a hub dyno would spit out 115 for my engine with mods?

Sorry, my USB cable doesn't work so I'll have to go home and take a digital camera photo of the timeslip.

i reackon u came off your throttle too early
hence the lower mph speed ?

nah serious mate there's something wrong with your time. Give it a few go. Btw what rpm were you launching it @

23-08-2007, 03:57 PM
where is the attachment? 72mph is unrealistically low but, maybe 92 for your ET sounds more right...

Each dyno reads differently. Your 115kW cannot be compared to someone elses's DC2 or DC2R run on a different dyno.

Everyone has said, your 72mph number is wrong. 72mph is not a 15.2s trap speed. Why? An Accord Euro which gets 15.8s traps at 91.8mph.

If you are asking for help and advice, you are going to have to be able to accept any criticisms and to think why you have some dodgy numbers.

In my opinion, the device measuring your trap speed was malfunctioning.

Maybe I did come off the throttle to early.

Here's the full dump of the data until I take a pic of the timeslip. Maybe it'll shed some more light on the issue?

Reaction: 1.023
60ft: 2.346
330ft: 6.498
660ft: 9.889
MPH: 72.42
KPH: 116.54
1000ft: 12.770
ET: 15.215
MPH: 91.59
KPH: 147.41
Over/Under: 15.215

OOOH. I think I've quoted the wrong MPH!! There's two. The bottle MPH is 91.59 which sounds alot closer to what you guys are thinking!

Which brings us back to the original question!

Thanks guys!

well there you go buddy, should check before you go jumping to conclusions.

And yes i guaranty you that, even if you had another 100 runs with the same setup you won't cut off a whole second.

I'm assuming you are on real street tyres
best case senario...

you get a 60ft time of 2.0 which would equate to around 14.6-14.8

23-08-2007, 04:43 PM
tats more like it lol :) Still , room for improvement ! Thats stock DC2 territory.
So get out and practice more !

23-08-2007, 04:45 PM
sounds much better...

looks right now.. just improve your 60ft and your time will drop into high 14's without an issue.

Thanks. I wasn't disagreeing with you, just a mishap on my behalf.

Which brings this thread back to the original point.

I think without stretching this out any longer, I'll get my ass down to Willowbank again, get a few more runs and see how we go before I come to my original question of why the car is only good for this time.

Thanks

Kinda brings my back to my original question though. A 115kw dyno tuned DC2 with my mods, is expected to run high 14's? I didn't think this was the case?

every dyno is different... Some dyno's you might get 98kw some 130kw...
cant really base it on much..

what was your kw pre and post tune?

Moya
23-08-2007, 05:19 PM
Didn't say mate.

It's all good though, I'm gonna hit Willowbank another couple times (for experience), then have it retuned by DynoDave and see how she goes. Then I'll hit it again and see how she goes after Dave works his magic.

Cheers

Dynodave tuned my vti-r, it also made 115kw... it ran a 14.3@96mph


This was with over 250k km on the original, unopened motor too... Very similar setup to yours. Let dave work his magic, you will not be disappointed...

Also keep in mind your DC2 'VTi-R' 1176kg is heavier then a DC2R 1117kg

That is nearly 60kg heavier (one asian passenger LOL)

Also with your 60ft(your launch) being 2.346, if you managed to get that down to a 2.0 you'll be quicker by roughly 0.692 sec with the exact same setup.

So 60ft 2.0 = 14.5 approximately

How much petrol did you have in the tank at the time?

A few tricks you could try before you head out next is:
-Remove Spare wheel+tyre jack+tools
-Have 1/4 tank of fuel
-Lower your front tyre pressure to 25psi and rear tyres to 35-40psi
-Do a nice burnout

PRACTICE PRACTICE PRACTICE! and Good luck ;)

So many mods and only 91mph..
Im sure ull feel a great difference once Dave tunes it...
That same MPH that my GSI teg was running except i got a 15.1..
untuned B18B with Cheapo 4-2-1 and custom zorst, stock honda ecu..
Ur car should SPANK it!!!!!
GET IT RETUNED ASAP BRO

Your times/speeds are fine.

Just need a better start ie 60ft.

Its your 1st run. You'll get better with practice. :thumbsup:

no way a dc2 will do 2.0. 2.1 or 2.2 yes.

For dc2 with those bolt-on easy 14.5's.

I wasn't going to post this but i figured i may as well give you a similar comparison. I've got a 1988 CRX (would weigh aprox 920-950kg at the track) which i have put a JDM B16A1 in it. Its got a 2inch exhaust and a microtech computer, which we road tuned. vtec set at around 5,000 i think and rev limiter set at about 8,500rpm (which i used most of at the drags hehe). After 5 runs i got

reaction: 1.057
60ft: 2.265
330ft: 6.221
660ft: 9.567
M.P.H: 73.77
K.P.H: 118.72
1000ft 12.420
E.T: 14.851
M.P.H: 92.23
K.P.H 148.43
Over/Under 14.851

I would assume that your car would have more power than my car with the mods you have done. The weight of my car compared to your car would be a huge advantage though.
Next time you go to the track, muck around with tyre warming (If you are using street tyres you will probably find that a huge burnout probably won't make a huge difference, but i would do a little one at least to get some of the sticky rubber off the track onto your tyres.
Then muck around with launch revs, probably go around the 4-5 depending on how sticky your tyres are, if they are hard tyres drop down to 3-4,ooo rpm.
Then try droping some pound in your tyres, try dropping the front tyres down to around the 20-22 pound mark.

I am not an expert at drag by any means, I've only done it 3 times just to see what my car would do. This is just some thinks that i have tried which made made the difference between a low 15 and a high 14 for me. and also some knowledge that i have gathered from 5 years of hillclimbing and circuit racing. Give it a go and see what happens. As everyone else has said, practise definatly makes perfect.
