I went to the track this weekend for the first time and was able to hit 14.7 at 96.12. As you can imagine my 60 ft sucked. (2.39)
In fact my first run down the track was a 14.9 @ 95 with a 2.5 60 ft. not very impressive for my mods but it was a great learning experience. (I learned never to race 96sleeper and expect to win)
I think if I learn how to launch a little better and do some basic weight reduction my car has a 14.3 in it.
On average I gained about 21 mph in the last 1/8th mile. I don't know if that is normal for MEVI + JWT 5-speeds.
What do you guys think?


Intake, Y-pipe, UDP, MEVI, JWT ECU 7200 rev limiter.
98 SE no weight reduction and about 50 lbs junk in the car. I weigh about 215 lbs.

 

Yeah you could hit a 14.3 or possibly a 14.2 with a good launch, like a 2.15-2.18 60'. 21mph is what I usually gained in the last 1/8. Anywhere from 20-22mph.

 

Post the slip details so we can get a better feel for the run.

What's the altitude of the track, and conditions?

Time seems slow for the mods, but you had a lot of crap in tehere..

What tire combo?

21 mph in final 1/8 is typical of a VI'd 3.0L. (pretty good actually) 2.39 is not good

Work on your 60ft and I'm sure you wont be dissapointed..

Where did you launch at, and shift at?

 

i think this run was interesting it looks like the mods you did are giving you anywhere from 40-50 extra horses. the trap was consistent of a 14.3 , 1/4 mile run. i think with practice you can see 14.3 easy with maybe the same trap.

 

im looking at some of my timeslips and i avg 21-22 mph the last 1/8th.

 

Yeah your time seems a little slow for you mods.

 

It's those 60 fts.. +3

 

What tires were you on?

 

Wow. VI and a tuned ECU upgrade make a massive difference.

14.7s is nothing to be disappointed with.

 

ok well my reaction time was hideous as well because I really didn't know what in hell I was doing lol. (1.333)
1/8th - 9.654 @ 75.99

It's the track in Steele Alabama. I looked for the elevation and couldn't find it http://www.alabamainternationaldragw...hevillage.html
As far as weather it was damn near perfect.

I have 240sx wheels with kumho ecstas 225/50/16 set at around 30 psi all around.

I launched between 2.5k and 3k and I shift right above 7k because I am paranoid of hitting the limiter.


It's crazy because on one of my runs I pulled a 15.1@96.79 with a 2.778 60 ft. So if each tenth off of the 60 foot equals about 2 tenths in the quarter I would have pulled a badass time if I had matched 96sleeper's 60 ft. in the lane next to me(that was his 13.7@102 with a 2.1 btw!)

 

hey good run, its my experience that a .1 off your 60 foot is worth .1 at the other end, thats how it works for me, but i do hear other people saying .2 at the other end but I personally have never seen it happen with my car and about 200 passes.

looks real good though 14.5 should be cake once you go again, maybe even 14.4 with a low 2.1 60 foot, just takes some practice. i mostly see 20 mph more from 1/8th to 1/4th and sometimes 21 mph with USIM.

will be exciting to hear what you do next time, you will definately put a hurting on 14.7 next time out, first time is always the worst time , lol !

way to go !!!

 

A good 60' for street tires is anything under 2.20. IMO anyway. 2.1 or 2.0 is ideal.

 

Practice, practice, practice.

The R/T will not affect your time, but it may affect who wins.

I use to launch at around 3,000-3,500 when I had my first Maxima, that ran 14.4's with Y-Pipe, JWT pop charger and custom exhaust.

 

not bad as everyone else already stated 60ft times.

 

Yeh I can't believe how bad you beat me in that GTP. What are some other good tracks that are a little closer?

 

How long does it take to get from Atlanta to Steele? I'm moving to Atlanta within a month or two and I want to run at Steele and also Silver Dollar down by Macon.

As for yout times. They'll only improve. Your ET and traps are a little slow for your mods, but I'm certain things will improve as you become accustomed to racing at the track. My first few times out with my Maxima, I landed mid 15s@91mph. With a no changes to the car and just a lot of practive, I got it down to 14.7s. With MEVI/JWT ECU, the car went 14.3-14.4@98-99mph with upper 2.1s/low 2.2 60 foots. With a low 2.2 60 foot, you're car will easily go 14.4s.

 

my guess is around 2 1/2 - 3 hours depending on how hard you push the g35. mapquest says 2 hours 27 minutes from atlanta to steele, but have to consider traffic now.

(steele)
map below: 145 miles


(macon) 1 hour 30 minutes
map below: 87.8 miles

 

other interesting facts:

Macon, GA : Elevation: 400 feet
Steele, AL: Elevation: 582 feet


are either of these tracks lower (elevation) than the Kansas drag strip

 

hey I appreciate the input. Steele was about 3 hours away for me. (Gwinnett County)
Yeh a 14.4 would be great.
There is going to be a Test and Tune almost every weekend in February at Silver Dollar raceway in Reynolds. If you happen to be down here by then it'd be nice to run your G even though I'm sure you'll kill me!

 

KCIR is like 1100' elevation, but even more importantly, Steele and I assume Macon as well are open all winter, whereas KCIR is not.

 

Yep, but I must admit that when I ran the 14.3 in my G, the conditions were pretty dang good with the calculated DA being almost sea level. However, like you said, Steele and Silver Dollar does stay open in the winter and they run even if it's 25 degrees out. KCIR is only open from March to November and that's only if it's 45 degrees and sunny. I've calculated the conditions at Steele and Silver Dollar in the winter and sometimes the DA is in the -1,600' to -1,800' range which explains why both these tracks can be rather quick.

We'll have to see though because KCIR got significantly quicker after they resurfaced the track and added new timing equipment back in 04.

 

So what would I have ran at an average track? 15's?

 

I looked up the conditions and when you ran the conditions (density altitude) were close to or just below sea level. So yes, the conditions were quite favorable, but nothing like the crazy DA the track sometimes sees. Running at -1,500 DA would mean you'd be a solid .2 seconds and 1.5mph faster.

Regardless, if you would have gotten a more realistic low 2.2/high 2.1 60', which is very possible with some practice, you'll be looking at 14.3/14.4 and I'd bet you'd improve the trap speed a little. 14.3/14.4@97-98mph is still REALLY good for any NA VQ30 4th gen.

 

Does improving my 60 ft raise my trap speed as well?

 

so, what trap speed could you see with the 00VI' accompanied with i/y/e/ecu/w 7200rev/ instead of the MEVI? Possibly hit 100mph ?

And, if you look at my time in my sig, why did i get such a low trap?

 

Probably not unless you got a really bad 60 foot like a 2.5 and was spinning badly into the 2nd. With my Maxima, I remember running a few 14.5-14.6@98-99 mph with low to mid 2.3 60 foots and then getting back in line and pulling 14.3-14.4@98-99mph with a low 2.2 60 foot. With my G35 I did a 14.6@98mph with a 2.35 60 foot and then did a pass 1 minute later and pulled a 14.4@98mph with a 2.20 60 foot. As you can see, trap speed really doesn't vary much. Trap speed indicated available power and ET indicates how well you can utilize that power through the run.

I had said your trap speed might improve simply because your shifting might get better. Are you shifting 4th or holding 3rd? You need to hold 3rd to the finish line with the ECU.

 

I'd think 100mph would be possible. I saw as high was 99.5mph with the MEVI/ECU/Y/hacked stock airbox/02 Max muffler.

It could be so many things. If the Key Value clutch slips on shifts, it's definitely the cause. Just a little clutch slippage can suck out a lot of MPH and ET.

 

I'm a pretty fast shifter and I hold out 3rd till the end. I mean 96 mph seems more like what a non-VI'd max should run.
oh well, 2 mph here 2 mph there I just wanna hit a low 14.

 

ya you could do better but unfortunetly its not a cake walk launching the maxima I ran 14.9 for my best but I can keep up with cars that have run faster times
