went to the 1/8th for some n/a times - Honda Prelude Forum

99Prelude_LC · 04-26-2003, 12:36 PM

ok at the last minute me and my gf ran up to the 1/8th mile, i only had 30 mins to run before they closed

CONS:
weather sucked, pressure was reallly low, humidity high
track was like a skating rink
back to back runs no cool off period, running at max temps
no tire pressure gauge

i was at 36psi in the front, i borrowed some mustang guys gauge but it only went to 20psi haha, stupid slicks

so i just randomly let some air out it ended up going down to 32

(i checked when i got home) i was hoping to get to 27.

PROS:
NOBODY THERE!, i got to run consecutively, got to the end of the track did a u turn and tried again lol.

The track was so slick, i ripped 3rd gear everytime and i barely could do that w/ the sc, never done it till now on the jdm motor. I did some long burnouts in 2nd gear which netted me my best 60 foot of 2.367, without a burnout it was 2.5s.... like i said, driving on ice.

60ft: 2.367
1/8th: 9.666
mph: 76.3

i was really happy with the numbers, thats a high 14 for that run, which puts my car at a mid 14 on that night with a good launch, which puts my car at a low 14 on a good night + good launch. just what i expected from the cars i've raced and just what i got

Well, not trying to rain on your parade or anything but with a 2.35 and a 9.666 1/8, you will be hard pressed for mid 14's. I ran a 14.3 with a 2.35 60' and a 9.32 1/8. Just tryin to put it into perspective for you. Even with a bad launch on my run pulling the same 60' as you, I was over .3 faster in the 1/8, and still only went 14.3.

i didnt' say that was a mid 14 run, i said that was a high 14, as in 14.8-14.9.

if i had pulled a 2.20 lets say THEN it would of been a mid 14 with a 76mph trap. probably around a 14.5-14.6

now if i went w/ better weather, let the car cool off, and got a 2.20 all like i've done in the past, then it would of been a low 14 as in 14.1-14.4

with the sc i ran 9.1-9.2 with 2.2 60 fts last summer @ 77-78mph only at that track.

Fast&furiuslude · 04-26-2003, 08:28 PM

LC's right,he could hit low 14's with a great launch. i ran a 9.890 with a 2.4 60 ft at 73.53 mph sp id say im a mid 14 sec car. nice 1/8 LC.

4bidden · 04-26-2003, 10:46 PM

Well say what you want but from those times the car doesnt appear to be putting down that much power.

So you are saying you'll drop .7 by dropping the 60 to a 2.2?

And you do realize that letting it cool off doesnt really do much, right? You would have to let the car cool for about 2hrs for it to make a significant difference. Once you make a run the motor is pretty damn hot and will not cool off to where it was for a while.

I'd say 14.3-14.4 is the best you can do unless for those runs you were racing minutes after it got done raining on the track.

99Prelude_LC · 04-26-2003, 11:35 PM

actually youd be surprised. i've been able to drop a few tenths and gain a few mph just by letting the car cool off before a run. i've done this many times, on many tracks, under many conditions and yes it always works. lol maybe you should try it

60'-- 2.310
330--6.377
1/8--9.661
MPH--74.87
1000--12.476
1/4--14.859
MPH--94.89

60'-- 2.263
1/8--9.466
MPH--75.77
1/4--14.570
MPH--96.05

2.27
9.385
76.31
14.510
95.34

just some random timeslips for your reading pleasure

PreludeRacer023 · 04-27-2003, 12:51 AM

hmm, very intersting, i was looking through my old slips heres one for you

60..... 2.340
330.... 6.316
1/8th.... 9.526 @ 77.04
1000.. 12.284
1/4.... 14.622 @ 96.39

to reach the 14.3 range your gonne need a best of 9.3 in the 1/8th..thats according to my slipsof course i have a slip thats a high 9.2..9.289 to be exact, an ran off a 14.0..of course you can see the power top end through my traps..80 plus 1/8th an almost 102 1/4... so id put your car in the high mid 14s..14.7 to 14.6..possibly a 14.5 with very good traction, but your traps will need to increase in the 1/8..still good though, i was there, slowly kept pushing forward and now im in the 13s..i havent beeen to the track since jan, im going this wed to play around just chillin, well see what i run..if i run, havent decided yet ill let you know, if i do run my GF will have the camcorder, but i still cant figure out how to load them onto the comp, maybe i can get someone to help if i get the footage..good luck though..peace

xratedSH · 04-27-2003, 03:54 AM

interesting.. just came back from the tracks, here is a typical timeslip

60: 2.328
1/8: 9.666@76.52 (same as LC on that one.. spooky)
1/4: 14.942@93.54

I had horrible traction tonight, may have to do with my alignment and tires. I rotated tires front to back since my front left had inner wear. car had mild wheelspin, until I hit the highcam and it turned into wheelhop, I backed off but this seemed to be a recurring them for the night.. also, where the hell is my topend? my best trap is 94.15mph, nowhere near LC's 96 there, and we have similar 1/8ths... oh well, I'm sorry, kinda babbling, but it's kinda late... lol

99Prelude_LC · 04-27-2003, 09:37 AM

maybe i should of rewritten this post, i must not of been clear, people are just repeating exactly what i'm saying...

a mid 14 with good traction IS what i said that puts me at that night. obviously i know im faster than a mid 14, the reason being that none of the things that night were ideal conditions. even with bad weather if i had let my car cooled down i could of easily hit 77mph, and if i went with good weather i could of easily hit 78mph.

so a good launch w/ a 78mph trap is.... a low 14! thast what i was saying i COULD run, so i now have a ballpark for comparison when i put the sc on.

i wasn't going there to get a good timeslip,i just wanted to know a range of what i can run n/a to compare

UZ 2 B AUTO · 04-27-2003, 12:13 PM

..:New SS=>5Spd. 1/8 mi. time:.. what mods do you have? why am i running this w/ 2.2 60 ft. times. i have aem cai aem pullies apexi n1 cat back koni yellow, neuspeed sports (set soft on front and hard on rear to keep suspension play down[as it was explained to me...this is good to do]) i do have drivers side motor mount broken (rubber insert) and auto ecu from my 5 spd swap and CEL is on..if that would even effect power...what can i do to get faster speeds and better times.????

4bidden · 04-27-2003, 01:43 PM

I guess it depends on what you call a low 14.

Neither your 1/8 trap or your 1/8 et indicate you are putting down that awesome of power. Since you had "no traction" I would imagine your traps would have been on the high side for the 1/8, but they are not.

Fast&furiuslude · 04-27-2003, 01:49 PM

whats the big deal what he runs. Its a pretty decently fast car in the 14's. blah. Hurry up and put that sc on.

with a 78mph trap that indiates a low 14, i trapped 78 at sanger w/ the sc and when i went to the 1/4 the next week at ennis i ran a 14.0 so yeah to me a low 14 is 14.0-14.3 see what i mean?

and its really not that much of awesome power considering my mods, its average power at best. if it was awesome power i would be running 13s lol

99Prelude_LC · 04-27-2003, 02:46 PM

Lewis: thanks

Tony:
I'm impressed you managed a 2.23 with a broken drivers side mount. when mine was broken the wheel hop was horrendous. All I can offer you for your better times:
1. weight reduction, take out your sub, spare, jack etc... if you have them
2. Raise the rear tire psi to 36+ it usually helps reduce the amount of parasitic drag.
3. check your weather that night, go when the barometric pressure is in teh high 29s, and if its in the low 30s run your ass up there. it makes a HUGE difference.

for example, the night on these runs the pressure was below 29.6 and 2 years back with just i/e and the pressure above 30 on the us motor, 14.7-14.9s!

also my mods are a little drastic for comparison, my old car you could compare and i'd probably be runnigh high 14s low 15s at best n/a like you, no worries, you're driving well! get teh cel fixed

JDM H22
Akimoto cold air
DC SS Header
Testpipe
Greddy PE exhaust
VAFC - lightly tuned (no dyno)
magnecore 8.5 wires
ACT HDSS clutch
Falken Azenis balding tires hehe
Front + rear sways
OBD II workaround
AEM Pulleys

this should be about 190-200whp tuned, at least 190 butt tuned the way it is now. in a car that weighs 2950lbs w/ out me in it its going to run a low 14 at best.

with the sc and 220-230whp mid 13s were at best. good luck post your times as they come

No way!?!? No way that car weighs in at 2950 without you in it. Have you actually weighed it before? My 4gen VTEC with everything but spare tire in it was 2750 without me in it. So that puts it at 2935 with me in it. You have some lead hidden somewhere if that car weighs 2950lbs without you in it. Don't go by what the books say. They list my car at like 2866.

99Prelude_LC · 04-27-2003, 07:08 PM

lol you'll have a hard time convincing most people a prelude weighs under 3000lbs (5th gen) my car weighed in at 2936 w/ 1/4 tank and no spare, 2950 is about what it weighs with teh sways on there. most 4th gen vtecs weigh around 2800.

4bidden · 04-28-2003, 03:05 PM

Wow, I'd have to see that with my own eyes. 2950 with no driver for even a 5gen is insane.

the reason they weigh more aside from the larger size, is that the body is a much thicker/solid. Its one of the reasons why the 5th gens handle so well.
