stock lxi, shifting at 5k, launch at about 2k (not full clutch drop)

what have u guys been gettin cuz i saw an 86 listed at 17.3?

[A18A]

i THINK i seen a stock carbed 3gee on here with 16.9

[MessyHonda]

lol next time red line it....well that is a lil high but alot of stuff affects our cars...like tire presure....launch ....wide tires.

[snoopyloopy]

shifting at 5k could be your downfall. the lx-i makes it's torque at hp at 4500 and hp at 5500 if i'm not mistaken. so point is, rev higher next time.

[Oldblueaccord]

I can run 17.0 with my g tech. that going thru the 1/4 in 3rd at about 86-89 mph. I have an 88 lxi its alwasy been pretty peepy accord compared to the others I have driven.

I go like 7k rpm in first and second or what every your car feels like it will go. Mine always pulled real good right up to the fuel cut in 1st and second.

[A20A3quippedbeast]

how many miles u got blueaccord?

[Oldblueaccord]

269K 205/50/15 tires as well.

but i havent g-teched it this year at all.

No mods other than a K+N filter cone on the TB prolly hurts more than it helps. Origianal exhaust . Elevation has alot to do with 1/4 times as well/ When I went to Montana I ran like 5 18.0 back to back do to the 5k' elevation.

I'd look at tuning . Timing /plug/ maybe your timing belts off a tooth its easy to do.

I take off a little less rpm as well. any spinning and your loosing ET in a big way.

Just for referance I have an International Scout II with a chrysler 440 motor run 16.0 and the same speed 89 mph. same G-tech same strech of road. So our cars are just slow 0-60.

shift higher, like shift at 6k instead of 5k and youll drop about .5 sec off your 1/4, and dump it at about 2600 rpm after a short burnout. You might get into the 16s if youre good

[speedpenguin]

When was the last time your plugs were replaced? How're your compression ratios hlding up? You can run lower times, but not if your car's in poor condition.

[A20A3quippedbeast]

update:

launced at 2.5k, shifted up at 6.2k, held 3rd thru tha 1/4 mile=

[Oldblueaccord]

See there dropped .5 of a second Nice.


Do you here the intake change over after 5k rpm ? that might make a differant as well hp wise.

Its mostly a clutch slip/feathering deal on start up to get the fastest launch one reason I dont really do it to much 1/4 anymore my clutch is going well over 125k miles.

[A20A3quippedbeast]

yeah i did..i think...tha sound changed slightly--i did a pretty fast slip since i have a new (broken in) oem clutch and she held

[EX-ileAccord]

My intake sound changes A LOT after 5k. I thought it was just me tho lol

no its the car hitting V-TECH, jk its the secondaries opening up.

[AccordEpicenter]

lol, i called it, .5 sec faster. On 88-89 lxi the secondary runners in the intake manifold open at 5000 rpms, that is probably the different noise you are hearing, it is usually quite a bit of difference in sound (i call it Pre-Tec)

[lostforawhile]

one thing is the horrible factory exaust. if you knew how loud these things were with a glasspack you would see how restrictive the factory muffler is to keep the noise down. in the eighties there wasn't a lot of tech with how to make a muffler flow good and be quiet. they just restricted ithe hell out of it. also one thing in older cars that restricts your performance is years and years of buildup on the grid in the converter. thats pretty universal for all older cars. a new converter or not having one will make a difference.

pre-tec??? lol is that pre-historic vtec :dunno:

[Gemini2003]

LOL @ Pre-tec

[AccordEpicenter]

taking the muffler off alone will net you a noticeable gain in this car. That, combined with a cai, weight reduction, and some other mods you should run mid-low 16s.

if i take the seats out in the back and the panels out in the back, will i see a big difference?? doesnt seem like its much :dunno:

hmm im thinkin about a muff cuz i dont really like tha sound

[gfrg88]

cut the fuker off!!! cut between the header and cat, that shit'll sound fukin mean and you could prolly get to 16s there :D

[AccordEpicenter]

when i did my 5 speed swap, my lxi ran 17.3 with the auto, pretty much stock. With the 5 speed swap, cai, no muffler, no ac, no back seat, no spare tire, bypassed coolant lines to the tb and intake manifold, other than that everything is stock, pulled 16.2 but after some tuning the car was running high 15s (was taking down accord 200hp v6s with ease)

[BITESIZE]

<---16.3. Clutch dropped at 3,000, shifting at 6,200 rpms, 20 lb.s tire pressure in the front, 40 lb.s tire pressure in the rear. Before 5 speed swap I ran a 18.3. :)

[A20A3quippedbeast]

no its the car hitting V-TECH, jk its the secondaries opening up.
so how does this 'secondaries' thing work? ive heard of it before but never really paid much attention. what is it? hows it work?

[Oldblueaccord]

theres a vacuum(drivers side) pull that opens a second set of butterflys inside the inake at high RPMS. Those runners are longer and hence make a little more power in the hi rpm range.

sorry, the secondaries need actually vaccum to stay closed, hench the vac charge canister to close them when there is no vac available at higher rpms.

when you hit about 5k rpm the ecu opens the vac line going to them letting the spring open them.

if you disconnect them they will stay open all the time. make sure you plug that vac line tho, i will leak constantly lol. you may lose some power in the lower rpms.

the distributor works the oposite way, it needs vac to advance at higher rpms. so it uses vac from the charge canister as well. not sure actually at what rpm the ecu does this.

[A20A3quippedbeast]

yea i get how they need vac. to stay closed, since at WOT, manifold pressure is close to 1 bar but...

how do u disconnect em?

[Vector]

how do u disconnect em?

you will see a vac pod attatched to a wheel on the drivers side of the intake under all vacuum hoses, just unplug the line from the pod and plug it with a screw. the line i mean.

[A20A3quippedbeast]

ic ic..thanks man

[AccordEpicenter]

leaving them open all the time youll notice a def tq loss under 4500 rpm, having ran the car both ways id say keep it hooked up so it opens at 5k, its much more optimal then leaving it open all the time imo

[A20A3quippedbeast]

yeah thats true i guess

This one I must add to no disrespect to you lost,,, but have you seen the size of those new factory muffflers, some are as big as a ford c4 trannny., however I have not been under a 06 acura or mistu evo. so maybe they get by somehow. I was looking for a new design glasspack that wont start rusting and spitting out chunks.
As for cutting your (NOw speaking to the thread poster)
times, yours dont sound bad for almost stock four banger fellow, practicing and perfecting your launch, shifting and concentration on keeeping the car in the staightest line possible to the finish. when your shifting dont start bad habits like looking around, moving the steeering wheel, ,:rolleyes: and you can cut another .5 or 1.0 off your time.

[Oldblueaccord]

well I made some runs

18.3 and 78 mph that was last week at night 54 degrees F

pretty bad


I went ahead and got a new cat exhaust and muffler since the old one was Original :) got my money outta that deal. I noticed little driveabilty differance but :

I ran a 17.61 at 81 mph same strech of road to near my house as well which helps.

somewhat of and improvement.I might mess with the timing a little and see what I can get outta it.
