very disappointed
sup org,
i hit the track last year and i went back almost exactly 1 year later. im losing faith in my max hopefully you can bring it back.
so this past sunday i hit the track.
byron raceway in byron illinois 66 degrees and sunny
mods
00 upper
00 lower no swirl valves
00 injectors and rail
00 rear coils
00 valve cover
adjustable fpr set to the 5th gen factory spec
summit rpm switch
custom cold air intake routed to the fender
shorty headers
unequal length y pipe
megan test pipe
magnaflow cat back
the whole exhaust is 2.5 from the collectors to the tail pipe
auto trans trango hd2 shift kit
i swapped my wheel to the factory 16s i didnt roll with the G35s
last year i ran a 15.3 at 90 with a spare tire, sub box, and amp weighing about 30 lbs
this year i removed all that stuff
15.1 at 89
im on the verg of selling my maxima

P.S. Not hi-jacking your thread, just trying to get more information tossed in...maybe it'll point out a specific problem you're having.

I had a '99 previously...5spd
I ran a 14.7@94 but that was without any of the de-K stuff.
I was thinking the de-K stuff might actually impede the potential due to the higher flow of fuel, i.e. running more rich. A tune would help that. But I haven't seen a dyno of a 4th gen with de-K items on it...nor have I seen many 1/4m runs from them.
(Running rich is an issue I'm sorting out on my '03 but for different reasons than de-K stuff.)
OP-Did you only run once? As said previously, post your slip(s).

Either the RPM switch didn't work or your power rod on the 00VI is broken. From what can gather from your track location and weather... DA was decent at around 1300 feet or so. A non working 00VI is worse than a 4th gen manifold. Lemme guess... your 60 foot was slightly better than last year.... but the car just didn't pull very hard once you got into second gear.

You are running very rich with those injectors.
Take a look at one of my older track threads, I ran similar times after I installed my 00vi.

ill get on that
i have a VAFC2 but im waiting on a wideband i dont want to tune blind and blow something up
thats what i was thinking
sorry i forgot to multi quote one more.
the car doesnt really seem to fall on its face but it doesnt feel any faster
with the old manifold i definitely felt it when it fell on its face this one not so much.
maybe the power rod is stuck open?

Check out my old thread also. After my 00VI swap I couldnt run faster than 15.7 then Jaypee_99 let me borrow his JWT ecu I instantly ran 14.9. Now I just swap 3.5's in all the maxes I buy and be fast before a tune lol.

I know the tune is important I just don't have that much faith in it I have a feeling I may give me maybe 2 tenths. I'm going to chech the knock sensor. But I checked the timing advance at idle and it was around 9.8-10 degrees BTDC

i was at byron that day. didn't get a chance to come over and talk to you because my buddy broke his 350Z's axle and other buddy was trying to learn to launch his GTR (drag racing noob) and my other buddy was trying to figure out why his mustang was running so slow.
as far as the tuning goes, being NA, you can do pretty much whatever with the tune and not have to worry about hurting your motor. since you are using 5th gen injectors at stock fuel pressure you are running way richer than a stock 4th gen, so your "tune" is actually worse than stock. you can lean it out a bunch and i guarantee your traps would go up. also, don't be too discouraged, DA was not bad that day, but that stiff headwind was probably robbing you of 2mph. also, you trapped 91 on one of your runs.
still not great, but that 91 could have been 93 without that headwind, and could probably have been 95 with a more optimal tune.
i noticed you were going in to the water and doing a burnout though (at least on the one run i saw). pointless on street tires, and possibly detrimental to your launch, it flings water all up in to your wheel wells which will then drip back down onto your tires and even a little bit on to the track surface in front of your tires, hindering your launch.

Yeah bro, you cant add all that extra stuff and not tune. Gonna run like garbage.....thus the poor times. I have a 3.5 and I had headers, intake, 3" exhaust. I did not add anything else because did not want it to run like trash. Once I got the TUNE...OMG!!! Car ran TOTALLY different. and only adjusting fuel is not going to get you that much more power. You really need a tuning option that allows you to advance ignition timing. Thats where you make REAL power at.....adjusting AFR will only get you a few more hp. Gotta pay to play this racecar game.

A tune really is important, I picked up an average of .6 of a second and 2-3mph from advancing the timing alone. I also picked up nearly .2 and 2mph from extending the rev limiter, though that was only from one pass with the extended revs working since my idler pulley failed shortly after.

In not really sure what net timing is exactly. But that's base there is absolutely no advance other than the ecu doin it's job. Plus it's difficult to get a "good" tune. My options are really limited. Not only do I have a 99 (depin and repin no big deal) but its an auto

9 or 10 degrees of advance at idle is normal. at WOT in the higher RPMs you'd probably see 22-24 deg.
with VAFC, when you pull some fuel, you'll indirectly advance timing, not a whole lot, but every little bit will help.

So the knock sensor is good. Unless it only will act up at WOT?

My first run they were at 35 I spun through first and second and ran a 17.6
Since a lot of people are emphasizing the "good driver" I'll just let you know what I do when it my turn. 99 auto
I have an auto
Pull into the water box and do a cool smokey burnout.
Pull up to the line until both the upper set and lower set of the twin yellow light bulbs on the tree light up so I know I'm on the line.
Wait for the tree and other racer
On th first yellow slam the brake to the floor an hammer the gas.
On the third yellow GO!
Spin once hook and run a sh!tty time
I've been to the track hundreds of times with every car I have owned. I'm confident in my driving. Plus I have an auto. All I have to do is mash the gas

Tune is probably the biggest issue because the bigger injectors. When I did 00VI pre-turbo with no tune I put down around 150ish whp and after SAFC street tuning I put down over 200whp with a collapsed flex section lol

OH MY GOD!
What did you tune with? Only the piggy back?
Well org I would like to say thank you. I believe my faith has been restored. Looks like all I need is a tune and then I'm haulin as$
