Well as was going to wait until i ran a better time but took the 2000 vi to the track for the first time along with my BF goodrich drag radials these are my street tires i drive 60 miles a day back and forth to work with and in the rain and i love them. I have about 2500 miles on them. I had jack and spare out and passenger seat out.

2.090
5.804
8.896
79.55
11.574
13.823
100.26

This time is slower than it should be, like i said. i wanted to wait to my fuel problems are solved i'am running rich because of the 290 cc's injectors. I'am going to dyno tune it with a e-manage and set the best switchover on the dyno. it switches now at 4750.
But i was spinning my tires alittle if i can get a 2.00 60ft and maybe i should lower the tire pressure lower than 20 psi?
Also i want to add that after the swap the car has been running very hot the car fights to stay under 200 degrees for water temp there was about only 30 cars at the track so there was no cooloff time. Next track i go to will have about 500 ft lower ele and i will have a lower thermostat and be tuned .
I do love my maxima

 

still nice times

 

Do you have the eManage already installed?

 

No not yet ,thats why i havent dynoed yet.

 

so what were yout old times with the stock IM? 13.8 is just sick!

 

Well my best with stock IM was 14.600but without the drag radials. My best i could get with the jwt ecu was a 14.69. Wheelspin problems .

 

what are all of your mods?

 

Kris, I'm going to try to get you the pulley. Hang in there brotha.

I've been working tons of hours to finish up some on going projects at work.

 

I'm curious too, even with the new drag radials a .8 second drop is still huge. I'm considering this as my big mod for the summer, so I'm really anxious to hear any more results. Again, congrats on pioneering this...

 

I believe his mods are pretty typical and not terribly extensive. He has a VI, intake, JWT ECU, y-pipe, exhaust plus drag radials and some gutting of the car's sound deadening and other things. I believe he's removed about 100lbs from the chassis and his car weighs in around 2750lbs without him in it. 13.8s@100mph are very respectable and I'm very happy to see that the DRs hook very well. I knew all it would take was someone who knew how to drive to prove that DRs really can hook, especially the FWD DRs he's running. If I get DRs and get my 60 foots into the 2.0s, I should be very close to 13.9s@99-100mph @ 1100' with an ungutted chassis and 40lbs of SFCs hanging below.

Thats my mods plus underdrive pully and pathfinder TB.
My car weighed 2755 at the track ,ive never taken out the back seat so next time i go it will be out and ill have the carbon fiber trunk on by then. It will probably weigh about 2685 next go at the track . To bad i weigh 250 myself

My best 60 ft was a 2.088 13.91 @100.21 this probably would have been a 13.7 but i only took first to about 7400 rpm.

Deezo thanks one i get that pully hopfully that will be another mod for all of us.

 

13.8? thats insane

 

I'd love to see you go head to head with Neal. I believe his best on 17" street tires is a lower 13.8@101mph with a 2.1X 60'.

Dave

 

May I ask what you removed in order to achieve this weight? I am always interested in what other's have done as far as weight reduction is concerned. Thanks.

 

You removed sound deadning material?? Yuck.......with it I can hardly stand all the noise now much less without any. More power to ya though bro. Now just have the 3.3l stroker with the vi.........and lookout.

Does that website answer my question? I couldn't find any info on krismax's weight reduction. Thanks.

 

I think we need to all chip in and get krismax to a dyno.

 

No doubt! 13.8, that's crazy! We should have a pool on what whp he's at! Crap, I wouldn't be surprise if he in the mid 200whp range with those numbers!

S

 

Mid 200whp?

I don't think so...full bolt-on 2K-2K1 DEKs don't even put down 210whp. His JWT ECU isn't going to add much peak power, just allow him to take advantage of area under the curve.

He's got light weight, gearing, and lots of rev-band to make a quick 1/4-mile pass, which is more impressive IMO since he's maximizing NA performance.

Once he gets JWT cams/HD springs, I'm guessing low/mid 13s. Don't forget...this is all on a 200K+ mile VQ.

 

Good point. It's funny because I know a few boosted maxima's that don't run that fast...and they are pushing like 270whp or so...but are also heavier....so this is just amazing to me.

S

 

Thanks..my goal on street tires this year is 13.4-13.6. Without any major mods. Next track season im hoping for 12's thats what all of this is for

 

Man, what I would do to get my 2nd gen to go that fast!

S

 

those are some awesome times. i'm guessing he's putting down about 220-230 whp. you are my role model.


oh and whats thise about a cooler thermostat?? I would definitely like to hear more about that.

 

Why is 210whp hard to believe? I made 204whp, so there is no reason to believe that he couldn't make 210whp with a better designed intake manifold.


Um, there is no way he has 220-230whp, that is a little optimistic.

 

jimes cooler thermostat mod.
my thinking is ill put down 210-215 fwhp. i hope

 

i want to know how did u get your car at 27** pounds?

 

cool. i think i remember seeing that thread. i'll have to go search for it now.

 

krismax

beautiful work and amazing time !
what size rims on the front ?

 

Not to discredit Krismax's 13.8s@100mph one bit, but let's not forget that Nealoc has run the same exact ETs (low 13.8s), but with a worse 60' (high 2.1) and trapping nearly 2mph faster. Neal also did it with just the MEVI, JWT ECU, Y-pipe, intake, catback, no real weight reduction other than a passenger seat and rear cushion out, and on 17" street tires. The key here is the 2mph quicker trap which suggests a bit more power over Kris' Max. Neal's race weight with this combo was 3005lb with him (150lbs) in the car so Neal's car is heavier too.

http://forums.maxima.org/showthread.php?t=299895

I'd estimate Kris' Max is putting down right around 200whp because he's trapping only marginally quicker (.5-.7mph) than many of us that are making around 200whp. Hopefully he will dyno soon though.


Dave

 

Just saying mid 250s isn't realistic when typical bolt-on factory DEKs can't even break 210whp. Add a JWT ECU, bigger TB, and some lower intake manifold improvements, which adds what 10whp NA maybe?

I don't think he's over 210whp in the current state of tune, however using a 1/4-mile calc, it says he's got ~224.5hp for that ET.

 

Krismax trap speed is deceptive though, since he's running a 5% smaller wheel/tire combo then stock. That helps the 60', but hurts his traps.

Their weight is equal with both in the car, so the big difference is wheels and krismax super pig rich state of tune. Once he fixes his AFR, he'll pick up 5-10whp easy.

 

15x7 kosei k-1's my street rims all the way around. Thanks for the compliments

 

Impressive

 

I don't think the shorter tires make that much of a difference. You can already see that his car doesn't quite have the topend even in the 1/8 mile. I'll let you know what I find out when I get my 225/50R15 DRs. IMO, if he'd set his rpm switch for ~5000-5100rpms and shifted around 7000-7200rpms, I think he'd probably be quicker. Opening the valves earlier is pretty deterimental to performance.

How do you guys know he really is running "pig rich" if he's never dynoed? I'm not saying you're wrong, but how do you guys know for certain?


Dave

 

VG-T that sucker.

 

Dynos and track times are a funny thing. My dynos say im putting down 185whp and 174ft lb but the track would suggest I'm putting down more. I don't put any stock in dyno numbers they are sortof ephemeral to me. It's like "wow I got great dyno numbers but at the track my car doesn't do what it should". You can only compare your dyno numbers to yourself, comparing them to other cars unless they were dyno'd on the exact same machine. Tire size is not a factor here as my tires are 6% shorter than stock. 235-40-17s as opposed to 235-45-17s.

Kris did you try any other shift points other than shifting right at redline?

 

My first run was a busted run i spun pretty good 2.296 60 ft 14.29 @98.92 i knew it was a bad run so i took it only to about 6500 rpm in any given gear. Second run got alittle wheelspin felt good but didnt go any higher than 7300-7400 rpm in any given gear. 2.088 60 ft 13.913 @100.21 . Third and final run and best 2.090 60 ft 13.823 @ 100.26 I took first to around 7700 rpm second 7600 rpm (i think this was to high) and third gear to finish.

Keep in mind that my 2nd to third shift is a granny shift my third gear synchro is all but gone.

I dont want this to become a ****ing match between me and neal. I respect his times and he gives me a goal to shoot for. And thats one reason why i continue to mod my car and love doing it.

Neal what are your plans for the future? Are you still going to boost?

 

Amen to that

 

You're probably correct. I've just always heard Jime and others say shorter tires help the 60', which does help ET, but traps suffer.

You're assuming the MEVI power curve, which from the DEK dynos isn't the same as a MEVI. Opening at 4700rpm requires a 4600rpm switchover. I'd bet he'd gain a minute amount by a slightly earlier switchover, but definitely wouldn't go past 5000rpm with the DEK manifold. However, his 70mm TB and port matched IM neck effect is something no DEK dyno has shown.

The MEVI and DEK are very similar in approach, but somehow the differences make a somewhat different curve. At least with a factory DEK vs the few MEVI dynos I've seen.

An extra 50cc and I believe he's mentioned cold startup richness.
