70 shot NOS e.t....should i be disappointed?
OK, I just got back from E-town...
Wanted to do a few tuning runs before Sunday's event...
I decided to jet it at 70hp due to traction problems...
Todays Nitrous Setup:
.036 nitrous jet (70hp)
.090 bypass jet (yields 80psi fuel pressure)- too high.
Nitrous bottle pressure= 950psi
Todays Track Conditions:
Temperature- 67 degrees
Relative Humidity- 45
Barometer- 29.55
Timeslip:
60'--- 2.240
330'-- 6.126
1/8--- 9.283 @ 76.56mph
1000'- 11.985
1/4--- 14.252 @ 99.46mph
(each pass was within 0.01sec & 0.09mph)
My E.T off nitrous is 14.8 @ 94mph.
The following could be some reasons why I only dropped 0.6 sec:
Stock y-pipe.
Stock spark plugs (stock gap).
Running too rich.
Any nitrous guys have any input?

That seems about right to me, I have a NOS dry kit too, on my Mustang, and on the 120 shot I only netted 100 at the wheels, so on a 70 shot, you should expect to get 50-55 at the wheels. And by my calculations, you picked up 5mph which is equivelent to 50hp. So without some mad traction, I would not expect to see much more from a 70 shot. I picked up 1.6 secs, and 13mph on a 120 shot, with slicks, so you're gonna need traction to make it work. And if you think it was too rich, try a little more bottle pressure, I have run mine as high as 1200 wth no side effects, and I usually try to keep it at 1050-1100 regularly.

Sorry not a nitrous guy, but that does not seem right. I would think that adding even 70 shot would drop your time by at least 1 sec. Wow! According to 2K2_6spd's analysis/comparison, everything looks like it's correct. Maybe you should be thinking slicks. I know a guy with intake, headers, ignition, and exhaust on an integra GSR with slicks hitting 13's! Call BS if anyone wants, but I saw his timeslip. I think just converting to slicks alone shaves a second off your 1/4 time.

You should move to 1 step colder plugs with a 70 shot. Usually a 50 shot is the highest you should go on stock plugs
Yes I think you are running to rich, IIRC some guys running 100 shots were at 85 psi fuel pressure.
I could be wrong but I thought I would try

Sorry, I'm just wondering how it's done?

with a 2.24 60ft on a 50-shot in a 4th gen....aftermarket y...I ran 14.0@99
14.2 isn't bad for what you have done...and for an un-tuned 70shot.
Un-tuned (rich) 100-shot, stock y-pipe...and a 2.4 60ft got me 14.0@102 (no traction at ALL)

You are running rich...you should be able to bring fuel pressure down to about 72psi and be okay but of course, check your plugs...
A y-pipe will definitely help. Even on a N/A Maxima, a y-pipe takes a couple tenths off. It will help at least that much for your nitroused car.
However, most important - traction. When do you spray and how's traction?
Hey BriGuyMax - Did you fix your fuel pressure problem (rich) yet? Which bypass jet did you end up using? hehehe

#1 .036 is a 60 shot ...
#2 you suck as a driver
#3 5th Gen's are slow dogs
#4 i will whip your a$$ all over NJ
#5 did you put the parking brake down?
#6 you should be disappointed
#7 you need a SARD's FPR .. well thats if it works with 5th Gen
#8 80 PSI is fine
#9 you are married now
#10 you suck

Slicks for sure,gutted some interior and I heard a Y-pipe but not sure he wasn't around his car much. He parked close to were we had our setup but I never saw him and I was looking for him.But the 70 shot was confirmed by a friend of mine that spoke to him. Anyway it was a damn good run for a 70 shot.

This is why I prefer to stay off the Maxima board most of the people here are lame.. I have a reason why a dry kit sucks get a NX kit and a Zex kit and I guarantee the NX will outclass the Zex everytime. So whats your logic behind a dry setup??

BTW, a possible NOS "backfire" and cost of installation is why most stay away from WET kits. However, NOS/Holley have a WET nozzle adapter kit that may change all that. Too bad it's close to $1500. It goes inbetween the fuel injector and bore, so you can inject N20 AND supplemental fuel DIRECTLY without changing/affecting the stock injectors. Hopefully, the cost comes down with time.

You don't hang around here enough then to make that judgement.

#2 take a class on sarcasm
#3 i don't use Zex.. i use NOS
#4 dry is easier to tune.. safer to use.. and very easy to install. much cheaper too.. that and the dry kit is much easier to combine with boost

#1 if you don't fully understand how it works or if it isn't tuned right, don't bother running it at the track!
#2 Dry vs. Wet arguement is overplayed ... both have thier advantages and disadvantages ... dragging that into the arguement doesn't help
As for the question, you should be getting better times. Sounds like you are running very rich. Below are some tuning tips that should correct your problem:
1) Get 1, preferably 2 step colder plugs - This will avoid detonation and keep things running a tad bit cooler.
2) Regap your plugs ... between .035" - .045"
3) Get the right gas pill ... running rich will slow you down, but it is safer.
4) Retard your timing! If you have no way of doing this, run slightly rich instead to avoid detonation.
Remember, nitrous is as safe as you make it.
