Track time from last night

[240ondrugs]

Last night I went to test and tune night at morosso motorsports park. Mybest time was 15.566 @96.76 mph. My r/t was 1.716 and 60 ft time was 2.612. This was on street tires and letting the automatic transmission shift itself. I think it sucks, what do you guys think?:help

With or without nitrous? Did you hold down the brake and rev the engine to 1700-1800 rpm? The auto 240sx's have a 1800 rpm stall speed so you can rev to that mark without damage.

[240ondrugs]

that was with the nitrious! launched car at 2000 rpm (held gas and break) squeezed nitrious at 3000 rpm. the 1st time I squeezed off the line and couldn't get tracktion to save my life.

[91nis240]

wow if i was running a 75 shot id be running a 14.0 flat very easily, sorry lol. but yeh that is odd to be running that time even in an automatic. I dunno man.

[Structure240sx]

thats is kinda slow. my auto 95 with cold air, headers and exhaust was hittin 15.6-15.7. are you sure the nitrous is goin through? wait the venom 400 might be *****in up the timing alot with the nitrous shootin.

[XCrunner19420]

Just look at the r/t, 1.716!?!?, did you fall asleep or something? you can drop a second off that and be in the 14's I believe

R/T has no effect on your times.the timer does not start until after you react (wheels must un-light the first of the stage bulbs).

I would go through and check the timingm, the O2 sensor output signal voltage, and probably rethink the nitrous nozle placement.

To atomize correctly you want the nozle as far away from the throttle body as possible on a dry kit. On the wet you want it 6 to 8 inches away.

What ti sounds like to me is that your O2 sensors are keeping your injectors open to 100% all of the time, and the venom module is trying to advance timing on top of that. I would switch the venom module of, and try again after checking everything.

nobody seems to notice the nearly 97 mph speed. looks to me like there is a severe traction prob, at this point I would concentrate on my driving with those r/ts and the time vs the mph that you had. Traditionally 98,99 mph is high 13s

good point. with ur list of mods i definitly think you should be in at least low 14's

still think u should turn off the venom

[nlzmo400r]

yea a problem is obvious, pinpoint it, fix it, and get ATLEAST low 14s, nice set up u have going, cool

[240ondrugs]

thanks for all the input im going to go to the track again and try some of your suggestions. on the street i feel so much faster than my times, but i know the track is diffrent.

[Structure240sx]

it was already said that reaction time has nothin to do with 1/4mi time. the clock doesnt start until u leave the line.

[Structure240sx]

its the bomex eye mask for the 95-96 240's. bomexusa.com look up s14

Yeah RIGHT,

[Structure240sx]

i have the timeslips from intake and exhuast which was 16.055. after i put on the header i beat every brand new stock V6 Camaro and Firebird i raced. They run 15.7's

so Automatic S14's are just as fast as 5spd S14's...

what where your 60ft times and 1/8th, trapspeed?

so your judging your 1/4 mi times but what you've read V6 camaro's and firebirds run?

[Structure240sx]

ok heres how everything was. i think i had about 116,000mi on the car at the time. injen cold air intake and custom 2 1/4" exhuast. i ran it twice at the track. it closed before i put my header on and opened after i started pulling it apart.1st run everr/t 1.28060' 2.472330 6.8921/8 10.490mph 67.42990 13.5471/4 16.295mph 82.76

2nd run that same nightr/t .83760' 2.405330 6.7631/8 10.323mph 66.66990 13.3451/4 16.055mph 83.91

and yea i've read that stock v6 camaros the ones with the 3.8 run 15.7's. i have two freinds both with 97's that i've beat and a brand new camaro on the street. i just barely beat them but i still did.

[Sygerwulf]

hmmm, maybe they just couldn't drive the camero's correctly? I've said it before, and I'll say it again. It's professional drivers that lay down the factory specs, not everyday people.

[Structure240sx]

good point. but these were auto camaros all you pretty much have to do is floor it. now someone will prob say that they will be slower than 15.7 so i'm an ******* again. but taking .3 sec off my 1/4mi time with the header is beilveable. it makes more power than any other bolt-on. look at technoman he has intake, header, exhuast, 5spd, maybe a pulley, iginition wires hes broken into the 14's. but no more aruguing about this its gettin too serious to me

[Erik]

I wasn't trying to argue about it, i was just curious, because,

i've never seen a automatic 240 mod for mod keep up with a 5spd, so either you have one exceptional automatic transmission, or those times are bogus..

[Structure240sx]

ill email u a pic of the timeslip if you want. i was tryin to attach it but im having a hard time resizing it.

[Erik]

it's all good man, i mean doesn't really matter what i think or say.....

every stock auto 240 i've seen has ran high 16s to mid 17's

[Structure240sx]

the guy i bought it from siad he took it to the track once and got a 16.5. i think he couldhave done better. i dont see how intake and exhuast could take off .5 sec but it was about 35 degrees out when i ran.

[Nismo_Freak]

With a low trap speed of 83 mph I dont think you will run 15.7s with a header. I gained 2 mph with a header and some shift point changes.

[96_S14_SE]

^^^ He wont... I have an s14 auto and have a decent amount of mods more then you. I have never gotten a 15.699 and a best of 15.70x at 65f. I mustered a 15.702 a half-year prior with about the same mods as I have currently (few mods where modded as well as some other things) but it was 45f out... Also I swapped from 205' to 225' rubber so I had to have gotten faster as my times dipped after that, plus Im pulling the 15.7 at 20f warmer... I also run about 87 - 90 mph traps...

Headders wont shave .3 Im sorry to say, especially in an auto. I didnt and I would have to say that with an auto, I gained very little from stock mani, precat, test pipe (had 2 cats) N1, to stock mani gutted pre and test pipe, to HS header secondary cat and N1... I noticed no speed increase with a test pipe and headder so I left it off, and run the single cat to save my ears.. With a manual I might have gotten more / something, but if I gained .05 seconds with it on I saw it as none for the god awfull honda sound it emited...

I dont mean to sound rude but its just not there. You also have to think about the transmission as it ages becomes even less efficient. Its like adding parts makes up for the loss of efficiency at times. Or the more power you put down on an aging transmission the more it slips, and the more you loose. I meticulously change the fluid with mobil1 synth atf as well... With a fresh transmission im sure I could be a bit faster, much in a the way a fresh clutch vs an aging one will. I have 111k on mine and have owned maintained it with mobil1 since 28k in 99'.

I may run again soon, but I lost my taste for the strip the second I punted a cone at the auto-x... That was back in sept... Ive remodded some things like the ram air (much better flow but its all internal smoothing ), and soon to be cams again so I may go back wed or so...

My mods:EI ram-air intake coupled with a jwt popcharger (see cold air post)Thermally wrapped HS 3" intake tube91' or 240-248 (soon to be 248-232 friday) cams.Dual Altima electric fans (one of my fav auto mods as it gave me .1-.2 and +2-3mpG avg)Accel wires (cheaper then oem as I needed new ones and less resistance)HS headderSingle turtle (cat, 2.5" TP netted nothing in current state)Apexi N1base timing of 22 - 24 depending on conditionsTB coolant lines removedEGR disconnectedupgraded grounds (if you call that a mod)

Then there is the suspension which doesnt really help but still:Koni yellows / progress 1.5" springsES poly LCA / Tension rod bushingswhiteline 29mm / 22mm swaysTanabe / Cusco, F / R STBEI tension rod bracket brace (replicated nismo power brace)EI subframe spacers

EI - Enigmatic Industries, or custom / rigged Probably something else but oh well..

[I30tMikeD]

Uh....sorry to butt in here but look at that 60' time. 2.6!!! that is what is making you slow. You can pull close to a second faster if you lower than to a 2.2-2.3. 96mph traps indicate a mid 14sec car.
