Ran a 14.1 N/A this weekend in my 4th gen... still in the hunt for 13s NA.
As some of you may know I made a few passes saturday on my slicks for the first time. Launching from 3000rpm and then 4000rpm, I bogged badly both times, running 14.45 and 14.35. After these passes it was clear that I wasn't risking my tranny, my clutch doesn't grip hard enough to do that, so I decided to give it a bit more on Sunday.
First run of the day, at about noon, I made a solo pass because the rest of the cars in my group had already done their final qualifying pass. I warmed the slicks up a little bit and then staged. I was feeling daring so I dumped the clutch from redline and wow did it slip. Instead of engaging like it usually does quickly the RPMs slowly dropped from 6500 to about 4000 at which time my forward motion and RPMs matched and I was off. I ran out 1st gear and tried to powershift 2nd, which didn't work very well since my clutch was now way too hot from all the friction. It slowly slipped from redline back to where the RPMs settled and I was pulling through 2nd. The shift from 2nd to 3rd was uneventful and I ran out the rest of the track in 3rd gear, hoping and praying my huge clutch slip launch had gotten me off the line well (it felt really good but I wasn't sure).
Here's how the timeslip turned out:
RT .835 (pro tree, takes some getting used to)
60' 2.002
330' 5.882
1/8 9.022
MPH 76.18
1000' 11.818
1/4 14.177
MPH 95.87.
This was my slowest trap speed of the weekend. I backed the 14.17 up with a 14.224.
RT .665
60' 2.100
330' 5.929
1/8 9.122
MPH 76.23
1000' 11.887
ET 14.224
MPH 96.72
This pass was only about 30 minutes after my 14.1 pass. I wanted to avoid so much clutch slip this time so I dumped it from 5500rpm, but that was in vain. The clutch was still hot and slipped down pretty badly, only netting the weak 2.10 60' time. Same story into 2nd gear, nice and slippery. 2-3 shift was uneventful. I got to watch an all motor Civic Hatch walk away from me which is unusual hehe. He ran a 13.17 @ 106mph. So I lost and was out of competition for the rest of the day, which is fine because I don't think my clutch could have taken any more 5500rpm launches today.
Today the weather was beautiful for racing except for the STRONG headwind. There was a stiff wind blowing right in our faces at the track, probably affecting ETs and MPH a little. It was about 65 w/ 50% humidity, but the headwind was direct and strong enough to blow my CF hood back against my windshield in the pits, and it had the flags extended to their fullest all day.
At this point it looks like the weak link in my quest for 13's NA is my clutch. With an ACT I wouldn't need to worry about clutch slip like I do with my OEM clutch right now, but I might need to start worrying about shattering the differential. So, still on the to do list are ACT clutch, JWT ECU, UDP and exhaust. With the ECU I might be able to power it into the 13s N/A, but I think I'll probably get my driveline locked down first and pick up an ACT 2600.
So, the moral of the story is, slicks do hurt your trap speed a little bit, but they are pretty effective at getting you out of the hole as long as you can keep from bogging in an underpowered car such as mine.

Nope VQdriver unfortunately I was unable to come up with the funds necessary for the ECU in time. Thus my run was made with my mods only, no borrowed mods hehe.
Details of my car are
MEVI set at 4600rpm
JWT POP
Cattman SS Y pipe
WSP Test Pipe
CF hood which sticks up in one corner and creates a nice drag effect
15" Mazda Millenia wheels with 6/26-15 M&H slicks.
Passenger seat, rear bench, spare and jack removed.

I was hoping for a 1.999 60 and I was only .002 away from that as well... weird huh.

Err well.... I was trying to keep this under wraps till after I pulled it off. If too many people anounce they're trying for that time then everyone will jump on the bandwagon.
Congratulations Neal on your accomplishments. Keep prying away at it and you'll eventually get that time.
And why on earth did they stick you with the pro tree??

Nealoc- I dyno tuned my MEVI this weekend and found that for my car 5100 was the best switch over for me. It is seamless.
I was wondering if maybe yours is set to low. I had mine set at 4800 and it was lagging the car a little. Just trying to help put you in the 13's

we're getting very close. i can probably only think of a handful that are actually within the realm of running that time. i'm still sort of far away.

Congrats Neal. Those are some pretty heathly ETs and MPHs (for slicks). I'd venture to say that the ACT clutch, ECU, cold weather, and no headwind (maybe a tailwind 
) will get you DEEP into the 13s. I'd say 13.8s with 2.0 60's is quite possible if you can round up those mods before the season is over. I've run in 15-20mph headwinds and it seems that my MPHs are most affected. Maybe it's because drag becomes an issue above 80mph? Same setup and the same conditions except for the 20mph headwind resulted in 2mph+ in the 1/4 mile. When I got my 97.79mph trap speed I had a 15mph tailwind.

As for the seats, I doubt it makes much difference (maybe .05-.1 seconds). We're only talking about 50lbs.

For the past few days, it's been in the 70s and the 4600rpms switchover feels absolutely seamless. The only thing I notice is the change in pitch of the intake on the switchover. I think the best reason for the 4600rpm switchover is that when you hit 3rd gear at WOT, you land right right above the switchover. It sure feels stronger with no lag anywhere. Hoepfully Neal will share his experience.

I was just curious if he tired any other switchover points?
I am sure neal and you have experimented with it and judging by his current times and MPH it seemd to be working WELL.
Just curious if he tried any other switch over points at the track.
thanks for the input.. need to file that in the brain housing group

SR20- I think that most people on here who are dedicated to drag racing (and close to the 13s) don't need others to prod them into getting mods in order to lower their times. They usually do it of their own accord, I know I sure did, and I'm sure you do too. The people that aren't dedicated to drag racing just don't care, so they aren't going to put forth the effort it seems to be taking to slide into the 13s. As for the reason for the Pro tree... I don't know. It was a heads up class called Street Performance, consisting of NA cars with both 4 and 6 cylinders, engine swaps allowed, slicks allowed on FWD vehicles only. All the street classes this weekend were on Pro tree, as well as the pro classes obviously. The only class that ran Sportsman was the sportsman (bracket) classes and the Fun Runs.
I've tried some various RPM switch settings and though I havent dyno'd myself, I was going by what the other people with 5spds have shown to be the best switchover on their dynos. My thinking is that in 1st and 2nd gear, you are winding out the RPM so fast that the small lag time it takes between when the set RPM is reached and when the valve actually OPENS is magnified, so hopefully with the lower switchover it will end up opening close to the ideal switchover point. For each car, the ideal switchover can only be determined on a dyno, if you haven't dynod yet, you have to go with what others have shown on the dyno, which is what I did.
I've only been to the track 3 times since having my VI. The 1st time I only got 3 or 4 runs, and my launches weren't very consistent so I comparison between runs can't really be made. The 2nd time I did try different switchover points, but something was wrong with my car and my traps were fluctuating 3 or more mph so I'm not sure that data is accurate either. The 3rd time was this weekend, and I only made 4 runs trying to figure out how to launch these slicks.

NICE
congrats on your new best time... who knows... maybe you will motivate me to start drag racing again... I think I need a new clutch if I want to race... it does not slip, but I just don't have the launch and shifting power that I used to have.

Re: Ran a 14.1 N/A this weekend in my 4th gen... still in the hunt for 13s NA.

Awesome numbers. I just noticed you don't have B pipe or even upgraded muffler, like a 5th gen muffler. Why not do those upgrades before the ECU?? It's cheaper and bound to set your Y pipe free
Also , it might be a better way to gage the benefits of the JWT ECU over the Nissan ECU on a VIMed NA Maxima.
Just a suggestion,

Details of my car are
MEVI set at 4600rpm
JWT POP
Cattman SS Y pipe
WSP Test Pipe
CF hood which sticks up in one corner and creates a nice drag effect
15" Mazda Millenia wheels with 6/26-15 M&H slicks.
Passenger seat, rear bench, spare and jack removed.

I think the ECU in conjunction with the VI will provide more significant gains than the exhaust will, but right now I have an exhaust leak so my exhaust sounds horrible. It sounds like an 89 Lumina with an exhaust leak, its really bad. I don't know what I'll be getting next... exhaust, ECU or clutch.

Sweet time! It's good to see a max like your representing out there.
however, you might want to change your sig quote. Just because someone doesn't post on the .org, don't assume that someone on this planet doesn't have an all motor sub 14 maxima.
