Now, I never dream, or if I do, I don't remember them. But this weekend I dreamed that I had installed a NOS system in my car, and loved it!

So, most of the day yesterday I rescearched NOS (read almost every thread on here that I could find...and some of those where damn long!) and I have a few questions that I couldn't really find an answer to:

- Is a A/F guage needed? Everyone says yes, but then goes to say that it will not be that accurate.
- EGT guage. Where can I get an Apexi one? Is that the "best"?
- Guys with NOS installed, can you post some pics of your interior setups? I don't mind guages, but I don't want switches everywhere. I was thinking that I would make a custom panel to go inside of the armrest.
- Can you unhook the bottle and take it out, if you're going on a trip or something and need the trunk space.
- How is the bottle mounted? Is it on the wooden floor board in the trunk, or attached to the body (metal) of the car?
- Can you get a guage to indicate the amount of gas left in the tank? I haven't seen anything like this, so I'm assuming no.

That's it for now...I'm sure I'll have more questions in the upcoming months.

 

its not accurate unless you have another O2 sensor put in the y pipe.. and if you have a EGT its not neccessary.. i don't even have mine installed..

i have an Autometer one and it works fine..


i don't have any recent pics.. i have one on the left hand side of the steering wheel.. and i have my bottle heater switch right after the shifter.. before the cup holder..



yes.. its real simple to remove the bottle.. i drive around with a 9/16 open wrench in my car.. if i need to swap a bottle or take it out real quick.. or go for a refil..

i have a custom floor board in my car and i hooked it up to htat..



yeah.. its called a Nitrous Pressure Gauge.. and recently they have the in car gauge also.. but you would have to run a nitrous line in the car..

i will be here baby

 

You are an asset to Maxima.org.

 

thank you Craig.. that is a real sweet thing to say

 

 

So if I had a EGT, Fuel Pressure, and NOS pressure (on the tank) that would be all the guages that I would "need"?


Pic? I've seen the Apexi one on Matt's page, and I like that one, its purdy..

Cool, that's what I figured

But that tells you the pressure. Now, I understand that pressure goes down as volume drops, but isn't that the idea behind a heater...to raise the temperature, and therefor the pressure? So, if you had a heater, wouldn't the pressure be close to constant?


thanks sweetie!

 

 

Sprint knows his stuff, trust him. Here is my interior setup.

Thanks for the pic. I've seen that one in another thread, but I don't think I want to take up my entire glove box. I would like to do the same kind of thing in my armrest though.

 

Why not in your window corner so everyone can be like Damn sweet!

 

Where? Window corner? I don't know what you mean.

I was thinking the armrest for two reasons:

1. I don't want to put holes anywhere there aren't any already. I like where sprint put his, but I only have 1 spot around my steering column.

2. I want to be able to hide them easily. If by chance I get pulled over, I don't want to raise any suspension.

 

yup.. thats all i am using with 100 shot.. my A/F gauge is sitting in my room.. if i decide to get another O2 Sensor


I think the Apex'i comes with a warning light.. i also think thomas said that the Apex'i will shut your NOS down if your FP gets too high or too Low.. kinda what the Fuel Pressure Saftey Switch does.. these are top notch gauges my friend..

these are pics of what my gauges look like..




they were cheap .. what can i say.. and the still perform..


yup yup..



well see the pressure will drop no matter what if the gas is low.. so if you have a heater and its on.. if you have no Nitrous in the tank the pressure will be low.. so when you are out of gas.. the pressure gauge will indicate this...




any time baby

 

My armrest is taken up by a fire extinguisher...I have no room in my car for anything!

Good luck,

Erik

 

oh when you ride in a car with a 100 shot.. its unfreaking believable.. and i will tell you what.. i envy the SC Owners because the boost never runs out.. as oppose to Nitrous..

BUT..

because SC cars have at least 50 ft tq less than Nitrous Maximas with both pushing the same horsepower.. its freaking crazy.. the first time i fired up 100 shot.. i got off the gas immediately.. because i got scared.. the car just picked up and went.. it was freaking scary i tell you.. the feeling i tell people.. its like God got behind your car and started pushing it.. its a terror.. ask dmbmaxima88 who tried to race me on Merritt i was pulling away from him easy.. and this is a 6spd maxima .. ask my cousin in his GS 400 who was getting walked when i was only at a 80 shot.. ask xsuperjoex (GS400 owner) from Clublexus.. who took off on me at 70 mph and by time he had 3 cars.. i took off.. and by 120 i was at his bumper.. i had to pull over in the next lane because i was coming down on him too fast.. then i pulled away.. granted i was on Empty on my gas Gauge when i raced him and the other two races were full tank races..

ask Synki.. he will tell you how scary 100 shot is.. as you see thomas racing Andi (BPU++ Supra)

 

You think you could handle a Lightning ? Too bad you can't hit the NOS off the line.

 

Why do you need another O2 sensor? Placement? Or is the signal not strong enough to supply the ECU and guage with info?

Also, if I'm not mistaken the Apexi has a Peak memory. That would be nice for when I'm at the track and can't really watch the guage. Any idea on cost? I haven't found one on the 'net yet.

What's involved with the install of each? I would imagine that FP would be pretty easy, but what about EGT? Do you have to go to an exhaust shop and have them modify your y-pipe?

Gottcha. I suppose that makes sense.

I just noticed that images name is ky.gif. Nice.

Anyone have experience with remote bottle openers?

Does using colder plugs hurt NA performance?

 

I have a remote bottle opener...NX brand. I like it because I don't have to get in and out of the car, but it is kind of a pain to remove it and put it back on....taking out my bottle takes about 15 minutes...its worth it to me...

I can def say a 100 shot is jsut damn nasty. Its sick in my *auto* but i can image what its like in Sprints car when he sprays too. 100 shot gives me wheel hop in first and just spins through all 2nd gear and some spin into third. This happened ti me @ Island Dragway. Im know a few of the guys saws it.

I know your most of your answers have been answered but i like to throw my .02 cents in as well.

Gauges needed arre EGT, FP, & NOS pressure. Why not A/F? The A/F is mainly for looks. Dont get me wrong, it serves a function but its not accurate at all. By the time it tells you that you're running lean, its too late. This is where the EGT comes into play. The EGT is more accurate based on exhaust heat.

Now, regarding the o2 sensor, if you want a A/F gauge, i woudl get a Tomei (spelling??). It is accurate buyt costs a good amount of $$$. It comes weiht its own o2 sensor. The reason why its better to have its own o2 sensor is this... the o2 sensors that youa re suppose to use off of the y-pipe isnt as accurate b/c the forn o2 sensor is for cylinders 1, 3, 5 and trhe other o2 sensor (*rear bank) is for cylinders 2, 4, 6. This means if you tap off of either front or rear bank, your only getting the reading of 3 cylinders. This is why having its own o2 sensor is better and mroe accurate.

I can give you some pics of my install. Sprint also has some of mine as well. You can PM w/ your e-mail and i will up them for you.

As for where my switches are mounted, they are mounted on a little black box i bought from Radio Shack. I wasnt too found of drilling holes around my arm rest.

I have my bottle mounted on teh driver sides trunk. Its mounted right down to the metal. There is a big gromet you use to stick the main tube down and run to the front of the car. Just run the main NOS line w/ the fuel line.

As for the EGT, you will need to buy a probe for it. You can take it to a mechanic or exhaust shop and ahve them drill a hole and weld it in. It is as simple as that.

To remove the bottle, all you avhe to do is disconnect the main NOS line and unbolt the scrwes that clamp the bottle down. I usually turn them hand tight so i wont need a wrench to take out the tank.

Make sure all your gauges are full sweep. Full sweep are easier to read.

I think using colder plugs hurts my car NA. It def doesnt run as fast but until its dyno proven, there is not definite answer. I personally use 1 step colder Plat plugs. You can also use teh Denso Iridium plugs. 1MAX2NV uses them wiht his direct port. He has no problems w/ perf at all.

The hardest thing about the install is tuning teh FPSS. Also, make sure the mozzle is facing the right way and facing dead on face to face w/ the trottle body.

 

my brotha stynki has answered your other questions so i shall sit back and wait for more

 

yes.. only after 80 mph though

 

i vote for making this thread a sticky. i must say i learnt quite a lot so far...

 

well matt did a thread like this once before.. it was a sticky.. but then it got taken down..

we should have a Force Induction Forum also.. where people should be able to ask Nitrous, Turbo and Supercharger Questions

 

I looked through Matt's thread, and found most of the answers that I was looking for...these were just ones that I couldn't find.

I agree about a FI Forum. No real reason not to.

 

That would be nice. I wonder who would moderate it though.

 

who else.. you know how we recycle moderators around here.. kevin of course..

thanks sweetie! [/B][/QUOTE]

 

All this talk makse me want NOS more and more everyday. Sprintmax it looks like you installed it exactly where I always though of having mine done. Was uit a pain running wires there or anything? Did you install it yourself or you and your cousin, or did you get it professionally installed somewhere?

SuDZ

 

Okay, next question...

What is the point of a purge valve/system. What's the cost? Worth the money?

 

from article at http://www.seas.ucla.edu/~cheston/nosxplained.html

"....A Purge Valve is just another solenoid that goes before your first nitrous solenoid. The purpose of a purge valve is to release or purge out the air in the line between the bottle and the solenoids. It bring fresh nitrous up to the solenoids so when you engage the system the nitrous will flow immediately.... "

 

Has anyone ever tried hiding your nos bottle so you dont get busted by the Police?

 

Yeah, I read that. I guess I was wondering about cost, and if it was worth it.

 

my cousin and i did the install .. it was pretty simple.. with a couple phone calls to synki here and there.. a couple instant messages to sx7r and Mardigrasmatt .. i was able to do it myself.. it was easier and less painstaking than changing spark plugs.. the hardest part of the install i would say was mounting the bottle.. that was it.. and thats simple.. i just couldn't figure out where i wanted it

 

the purge kit is a great tool.. i havn't gotten one but synki has one.. its great for getting your first hit of Nitrous to hit very hard... i usually just do a quick run and then thats my purge.. the NOS doesn't hit hard.. but its cheaper yes i am cheap the only reason i would get a purge kit to be honest with you is to taunt rice boys at the stop light

 

So basically its a BOV for NOS?

 

not really.. BOV releases boost pressure during shifting so that the boost isn't allowed to enter the combustion chamber during periods of low fuel delivery which could potentially cause too much leaning out of the A/F mixture and spark detonation. A Purge Kit releases AIR that maybe in the Nitrous line .. you don't need a Purge kit as the air will come out on the first hit.. but you need a BOV.. or you could see your engine go bye bye

 

No, I meant in terms of its "taunt rice boys at the stop light" use. I know what a BOV does. I ain't that dumb!

 

That is why i have mine.

They fear NOS.

 

didn't say you were dumb E.. but we are educating everyone with this thread and i wanted to look smart for once yeah.. same concept if you look at it that way

 

i have a question... i keep reading about upgrading the fuel pump to compensate for the fuel pressure while using nitrous, what happens if an upgraded fuel pump is used on a car with no nos in it? is it going to to run rich all the time?

 

no.. because if you think about it.. i hardly use my nitrous and i still use the pump.. it still goes to 50 - 55 PSI at WOT just like the stock pump
