wow wow wow one preatty slow maxima
so i was looking at the true stock number in 1/4 mile stickies and i noticed that auto get high 15's. i assume high 15's is like 15.8 15.9, i went to the track and i got best 16.4 and like 83mph. thats alot of powerloss. i litterary need like a Y-pipe to even come close to stock numbers. what is happening here. NYPD arnold sugested that it could be my VIAS, but besides that can it be anything else. and if it is my VIAS does broken vias really able to cut your power like that. i'm like ready to cry here. i don't want to spend money of after market parts just so i can compete with stock maximas. please suggest some fixing for me. thank you.

arghhhh, one of my coils went out like 2 weeks ago, i replaced it. as for the maf i'm really not sure. i was thinking of getting an updated one just to have an updated part in my car. the car sometimes feels like its slugish, but other times it feels like a true performance car. so maybe it is the maf.

IMO it's MAF because all coils can't go bad at the same time and with broken VIAS you would not get even these numbers. Check the stickies on how to diagnose VIAS though.
BTW: Are you sure that it's not an old air filter?

oh wait i lied, i just found my time slips. my best run wass 16.234 and my r/t was .662 i don't know about rt, is that good or bad. but still, even with that, supposedly i should be hitting high 15's. and its not the filter, i change my filter like every 10000 miles, i figure 11 bucks like every 8month isn't a big deal at all.

there are always factors though...the timers on different tracks may be "off" be a few hundredths.....the wind on the track (tailwind or headwind) has an effect. The temperature and humidity on any given day can affect engine performance and power....the tires you use can affect your traction.
All in all, I wouldn't worry about it. .5 second give or take is pretty standard unless you're positive you are launching at the correct RPMs, have a perfect R/T, etc etc....
not likely anything is wrong with the car though...

Why not post your slip or the numbers.
r/t doesn't really matter - I've redlighted and been asleep at the wheel - it happens. You can have a consistently great r/t and be doing something else wrong that kills your times.
More important is your 60' time. What was that?
How did you launch and at what rpm?
How many runs did you take?
In any event, a trap speed of 83 mph is not good.
there's a lot of variables to consider.

Well, if it was 2.8 that explains a lot.
I don't know what autos typically get but a good 5spd 60 is 2.20 or less. I think average is 2.3s.
From what I recall, a general rule of thumb is every gain of .10 on your 60 ft. equates to a .20 gain at the end.
I'd look to see what the average 60 is for autos - if you are .2 or .3 above then that's the difference.
Before you worry about vias, I'd work on launching or go to a dyno.
Heck, I've had some pretty good times but I've had plenty of bad ones that are directly the result of poor driving!

are u running 92+ gas?
what were the condiditons at the track/temp humidity?
what kind of tires/ wheel spin?
are u up to date with all your retine maintance?
theres alot of factors that can add up to a bad time.
i only took my car to the track once, it was stock esp for better tireas and maxspeeds which kept popping. 96degrees out full take of gas and my system in +100lbs. found out later my maf was semi blown, didnt knwo it could do that. ran 15.7 was the best i could do. i was decent at stick then .i had good r/ts and 60foot, but i dont remeber the exact numbers, i was too upset about my 15.7

Only had my Max at the track once, 100F track temps, full trunk of krap like tools etc, bad VIAS, and brand new clutch/flywheel setup with only few hundred miles. Only power mods where Greddy catback, Ypipe, CAI, flywheel and ACT clutch. I ran 15.1@94MPH, I was severely dissapointed also. I havent been to the track yet, my car is more less a dyno queen and autoX car. I suck at drag racing.

oh man i just got happy my car was ok and now i'm worried again. my time slip goes like this
Temp F. 60
Relative Humidity 96
Absolute Brometer 30.07
r/t .662
60' 2.443
330 6.863
1/8 10.492
mph 67.91
1000 13.589
1/4 16.234
mph 84.88
maintenece was done a little before i went to the track. my tires at the time had very little thread on them, so i din't get like insane wheel spin but i did get a little bit. and i also have 17" rims. i hope this helps, i'm gona go dyno my car hopefully like next week. i live in nyc and just recently found a place where i can dyno. what are the numbers for a 2000 auto se sopposed to look like.

what does everyone think he should be running?
like 15.5s or does that seem too fast for the stated mods?

thanks i'll def will look up old threads before i go to dyno. it just makes me sad, how a great car like a maxima can have this ghetto problems which are so complicated to figure out. american cars are so much more simpler, you know when something breaks becuase it falls out.

at the track i launched at like 2500-3000, u can launch higher cause the track is, or at least should be, much grippier than any street. at 1500 u have to wait longer for ur power to build, which can lead to slower times

r/t has nothing to do with ET, trap speed or launch technique.
as stated, a 60' will be much more indicative of how well he got out of the hole, but even then 83MPH is pretty bad, AFAICT. even on a bad launch, you should still be able to play catch up.
a half second off the 60' time is worth about a full second off the ET, however.

if you have 3 runs at that trap then I would say maybe.
But if you just have just 1 run then it could just be a bad run.
My 1st time at the track I trapped 96 MPH at 14.8 and 14.3 so I don't figure
Last time at the track off the bottle on street tires and all the other Bolton's I trapped 89 MPH with 15.50
and my best so far is only 2 mph faster trap and 1/2 sec quicker.

actually human reaction is .2 secs and i heard "see the first, hit it on second, be gone by the third..." at least thats what the older guys @ gainesville raceway told me. i'm gonna stick with that seeing that they were trapping .002-.005 on average and i dropped mine to .011 this is especially true for auto's. i wait a little longer b/c i have a 5spd. good luck though, for some it just takes time.
