Well I went to the track again yestserday, I removed the front and rear seats, same 2k2 titanium rims on street tires, my bottle pressure was at 1050psi.
I still have the same setup with the rpm switch, nitrous comes on at 3k and off at 6k (before the auto shifts)

For my 1st run, i berly had a chance to brake torque so i basically launched from almost idle or lil below 1000rpm. I took off without any spin but since nitrous dosnt turn on till 3k i had alot of lag between launch and 3k, and thats where im loosing time. here is my 1st run slip.


For my 2nd run, I launched the exact same way, i held the brake but the light didnt give me a chance to rev a lil higher (always gets me by surprice).
Also this time I removed the 6k pill from the rpm switch so that I could spray inbetween shifts, it turns out it didnt make a difference wats so ever, the previous run was better by a few hundreds.


For the third run, I put back the 6k pill since it didnt make a difference. I also switched to the other line without knowing that it wasnt as properly prepped.
This time since my 60' wasnt great (2.3) in the two previous runs, i got a lil more ready at the light and brake torque passed 1k maybe about 1500 or so, but as soon as i took off i just spun alot off the line, and since i was closer to 3k I didnt have enough momentum for the nitrous and didnt get great traction with it, also as i was going down the track in 2nd gear it felt as if occationally the tires would slip, this was my worse run in every aspect, 60', trap, and 1/4 time. Only if i could launch the same but actually hook, i would definitely do alot better.

 

WERD! now get to the tree before the other guy and you should have enough time to launch right.

 

Nice times. Get off the line better and you'll be close to 13's. If you want any tips in that regard for auto, talk to Jime.... but I don't have to tell you that I'm sure...

 

He has a shrine of Jime in the attic, with candles and lil bottles of Mobil1 ATF around it. Nah j/k LOL. But yea DRs or slicks are a MUST at this point.

 

Nice times man. Now you need to install that pump, 2 step colder plugs, cutout, slicks and afpr.

 

actually, jime, grey99, n couple others have helped me alot and given me great advice. basically everything i kno iv learnd from asking one of those guys or reading their threads. hopefully my next visit ill be with slicks.

 

Nice time man. I can see you going 13's very soon. Your not running on colder spark plugs?

 

thanx, yea I always have 2 step colder plugs on my car, even for n/a

 

Cool I'm going to be watching your times and mods because I'm thinking about getting nitrous sometime soon. Are you still on your stock tranny?

 

nice job what shot was you running. i ran a 14.4 @ 99mph with a 75 shot with street tires back in the days.

 

ajcool, yea its on the stock tranny with mobil1 fluid, drop resistor, and cooler

CMAX, it was on 75shot. 14.4 was my previous visit to the track, this time i improved to 14.2 and 97. hopefully next time i can get into 13

 

i couldnt get that low, maybe because of my system and 17 in chromies at that time,lol. good luck with the thirteens, your probably gonna need better traction for that one maybe drags or slicks.

 

nice job! keep it up!

 

YAyyyy 13's are right around the corner!

 

Have you done any runs with your current setup with no nitrous?Or close to your current setup with no nitrous?

 

nope, iv never ran all motor.

 

What are your mods? I am hoping for these numbers right now

 

00VI, ypipe, catback, CAI, UDP, cant think of anything else, i always miss something lol. if it matters progress springs with gr2's lol. and ofcourse the 75wet shot. I am still untuned though so my a/f is probably all over the place or very rich.

 

Ya, AF tuning will help, what are you gonna use?

 

well i dont have plans to tune any time soon, but when i do it will be VAFC2 to tune and control my VI

 

Do you try the Shift_Fast mod at the track ???

 

nah im to scared of using it with nitrous incase i hit rev limiter, and i didnt get any n/a runs cuz alot of peole were getting there and i didnt think i was goign to get enough runs.

 

i have the same problem with my extended rev limiter, i move so fast that i cant catch the shifts and hit the red line really hard. so i just leave it in drive and go for it.

 

do you have the Shift_Fast mod done? because if ur using the shifter, thats pretty hard to use that quick. jime and grey99 max already working on an automatic version of it so that it shifts using the MSD rpm switch at w/e rpm u want. look into that.

 

i've been reading up and watching but i havent done it yet. its a p.i.t.a to try and manually shift when you red line in seconds,lol.

 

Get some slicks and spray off the line and you should run low to mid 13's. I have been using the automatic version of the ShiftFast mod for the last couple of weeks and it works great but I wouldn't suggest it unless you have headers and maybe cams. All my best nitrous times were using the stock shift points in D.

 

Thanx for the advice, wont spraying out of the hole at low rpms with 75shot hurt the engine a bit? since NX recommends not to spray below 3k.

I wont be going to the track unless i have slicks, hopefully soon. I am also trying to find a test pipe to remove my gutted cat and put a cutout on that pipe, maybe that can help a little bit since the more freeflowing the exhaust the better nitrous will work.

 

Nitrous can be engaged at any time in 1st gear. Most nitrous company's will generally tell you not to spray below a certain RPM to cover their ***.

This is what NX says in their install manual.

"Never "lug" your engine and hit the nitrous
system, use the system at wide-open throttle only,
nitrous should not be used below 2000 rpm's. If
you do any of the above a serious "Back Fire"
could result in engine damage."

However they clarify it with this statement.

Q. How high must the RPM's before activating nitrous?

A. The RPM level is not as important as is the motors ability to rev freely when the nitrous is engaged, I.E. If the vehicle is in low gear, nitrous can be engaged at any time, but if the vehicle is in a higher gear moving at a slow speed when the nitrous is engaged the engine will detonate and damage will occur.

I have always used nitrous in 1st gear from an idle and never had any problems, just don't do it in any higher gear because of the inability of the engine to rev freely as stated above. I have sprayed out of the hole with a 150 shot many times, traction is your problem not blowing up the engine from spraying.

 

werd, i spray out the hole with no problems i just dont do it because of traction issues. you definitley need slicks for that, plus with a auto as soon as you stomp the peddle your at 3,000 rpm's anyway.

 

cool, now i feel safe spraying out of the hole. Ill go back as soon as i get slicks, already orderd a cutout im going to put on the cat's place. Maybe that can help me out a lil bit but im not depending on it 100%.

thanx for the info.

 

hey all these nitrous guys are running 12's with slicks? Streetz the vid your boy saw when i ran a 13.00 i had like a 2 second 60 foot on street drags, and the car was pushing about 338 whp. I think that the location and track has alot to do with the times. I have seen some vids of maximas running low times in a cold *** place and some of the tracks look like they are on a slope??? has anyone from up north ever came down to south fl and ran their cars before? just wondering?????

 

Well yea thats true, we also picked the hottest month to go to the track lol. most of the org nitrous guys are from up north with nice cool weather. im sure by the time cold season comes ill have slicks by then, I could have probably ran a 14.0 on a cooler weather. Or perhaps weather dosnt really affect FI(or nitrous) as much as n/a. either way like jime said i think i can expect mid to low 13's with slicks and spraying from the line.

 

Hey, who has a software to calculate 1/4 times based on wheel diameter n stuff.. i am curious on wat 1/4 time will I get with 22" slicks. considering my 60' of 2.3, trap of 98mph and 14.2. If i was able to pulls off a 1.8 60', with the same power as i did previously and 22" diameter wheels, wat would be the 1/4 time?

 

Up north in Kansas, it has been at 100F or over for a month - the last time I was on a strip was July 5. It's been way too hot - yesterday it reached 105 F.

The brave fools that went out anyway have reported track temps of 150-160 F. I'm not spraying in that kind of heat...

We might get a break in 2-3 weeks, about when the rains start up again.

 

yea, sometimes it gets so hot here that i think we are the only city that gets this hot lol. when i open the cars door it feels almost identical as when you open an oven after preheating lol, u feel the hairs on your face burning.

 

Yup, when it's too hot to breathe, it's time for a margarita - inside, somewhere ... Daymn, this heat is getting old - I've got things to test! Like the automatic Shift_Fast - it's now tied to the Tach output on the ECU. Heh.

Most of the country is too hot this summer. Of course, when the ice caps and glaciers finish melting, Florida will be under water...

I'm putting street tires back on the Max and driving 550 miles to Denver on Friday, for a family thing. Hope it's a little cooler there. Maybe snow tires ??? lol Still, 28 MPG makes that a one-tank trip.

Still thinking about the new tires, I see. How well do your local tracks prep? Lots of VHT and scrubbing? If so, you could really hook up better.

 

i think i was on the track that day. you have a white max?

 

nah, i have a green maxima, there were two green identical 4th gens, one turbo white 4th gen, and a white 5th gen.

 

The one missing all the gears was me.

 

BTW golie iv been told the track has been repaved n stuff and wasnt in great condition, so i probably wont be going back till they put new rubber on the ****
