Nitrous, Anyone use it?
 

Low cost, under 2K, only use it if you need it. 150HP. Will be installed with a electronic progressive controller, mapped to RPM and gear, WB O2 auto-cutout to protect the motor, and all stealth install. This would be a two bottle system remote valves at the bottles. All located in the spair tire area. Goal would be 400-450 RWHP in 4th ,5th , and 6th gear. around 350 in 2nd and 375 in 3rd. All with a smooth rise in power so as not to loose traction.


A guy at work has a 525 RWHP TT 350, and he can't get traction to use it. I want to be able to hook-up. I have been down the turbo road see bike in Avatar.

meh, i'll pass, only thing i wanna worry about refilling is my gas.

that fast furiuos crowd uses it.

The only Nitrous worth a damn is the stuff off the top of a Redi-whip can or from my Dentist.

Do it and post videos / dyno graphs.

Buy some drag radials you will hook

Nitrous is a renewable power-adder. You're going to pay for the system and pay everytime you press the button, hit the rpm switch, etc. If a person can save 2K for that system.... save some more and get a s/c. The power is always there, no need to refill a bottle, and no need to worry about bottle pressure/temp.

:rofl2: < on Nitrous

This is your brain on drugs....

This is your Z on Nitrous.....

I heard jnaut uses a small shot of nitrous.... :ugh2:

Last time I used nitrous, I was driving a slow-elica. NO2 is a waste of money if you ask me.

Stealth! At $25 a fill, and less than a bottle a month. SC is an option but I do not want to add weight to the front of the car. Fiberglass bottles in the rear is the plan. I drive this car 110 miles a day, on days I can't ride my bikes. I'm looking for the extra power to run up with the C6 vettes say 425 HP.

Is nitrous hard on the engine?

if you continue to use it.

It is all in the tuning. 150 shot sounds like alot for a not nitrous built motor. I am not that familiar with it on tight clearance motors of the import kind but on domestic v8's they set the piston ring gap pretty high. I little more blow by but much saver for the motor. My s14 had a chevy 327 what was gapped for NOS and all it had was 150 shot. I have heard guys with BB chevy's runing 500 shot, but those are dedicated drag cars. I guess it depends on the motor. I talked to a tuner in Ft Worth that recommended only a 50 shot and no more for a stock S10. The owner got bored and put the 100 shot jets in it. He blew his intake through the hood.

It spikes the cylinder pretty so quick that it jars your lower end pretty good. There are people they use all the time and have no problems. It gets a bad rap because it never messes up a little bit. If it only takes out a piston/bearing/rod you are pretty lucky. I got my S14 because the previous owner had a 406 (bored out 400sbc) in it. He was turning 10.90's w/ 10in drag slicks and a non lsd rear dif. It had a wet 150 shot of nitrous til it ran lean and "scattered the motor all over the track".

Nitrous is like drugs, the more they use it the more they want. Until they blow up the engine. ;)

Oh like drugs, then let's just say NO to NO2

Sounds powerful but not for me. It gives perspective to "enjoy it destroy it"

Go ahead give it a try and keep us posted, to see the 1st engine blown by NO2 on a 370Z! :ugh2:

No thanks to "give it a try". If I am going nuts for power, I'll put on the turbos. In the mean time I'm going to test those new coil overs. Yee Haw. :tiphat:

I was the same thing about turbo bikes and boost (I stopped at 15 PSI), the AVG was 2 motors a year for most of the user group. I ran 2 years and still have the same motor, NO BOOM! I'll take it slow and report back. Should start the build in 4 months. If anyone has some useful data please shoot me a PM.

I squeezed in my old Mitsubishi back in the day. My friends and I did the stealth install which I think is a must if you decide to do it. I got pulled over multiple times and the cops never saw it when they inspected under the hood. As long as its done right and you keep your ears and eyes open to any sort of noise or vibration you'll be fine. The key is an even distribution to the cylinders, so keep an eye on your spark plugs and make sure they look evenly smoked. It's not like you'll be squeezing all the time, maybe except the first bottle.

It can be if its not built, I havent searched to see if the VQ37HR uses the same pistons as the VQ35DE but the vq35 used hyperutectic pistons (lightweight, relatively cheap for production) There sturdy enough for regular use but nitrous is very rough on a engine. I have a friend that has nitrous in his SE-R altima with a hundred shot, he went thru 2 engines before finally building one with forged pistons. The #5 piston would always crack its upper ringlands on the piston. If I recall correctly he had it set for 100-110 shot, wet setup. After he put the third engine in he went to a 125 but made it direct port with throttle linked actuation for the lower gears like what the O.P. is talking about doing.

I could have used it last night. went to pass and the other 370z hit the gas thinking i wanted to race. I got around him and back into my lane as another car topped the hill. After he turned around and went back the other way. 75 extra hp would have solved the problem much sooner and at a much lower top speed....

Nitrous is like a tease. That's why I prefer turbo(s).

Dont let them scare you, I was heading down the N2O route with my 350Z and as long as you buy quality parts and take every saftey precaution and get a good tune you will be fine..... with a 100shot you should easily break the 400whp barrier.....

This is the key. Almost every nitrous engine blow is due to someone not paying for the safety parts needed or going too high with a dry nitrous system in the first place. Nitrous adds the extra oxygen to your setup, just like a TT or SC and you have to take at least the same precausions plus a few others. Many see nitrous as a cheap quick fix and don't do this. You need a fuel pressure safety switch, wideband, and a window switch at the minimum. This will probably double the cost of you setup.

WB o2 I have now. I am starting with the ZEX kit and the 75 HP jets. If I like it I will work up a computer controlled pulse modulated setup.

There was an article in either DSport or Modified Magazine with an article on the 3.8 Gen Coupe with NOS. Looking at their bolton set up, they have less hp than us but more torq... Anyways I think he was putting out 360ish to the wheels and 320ish torq.
That is amazing!

Yea it was DSport. They had a Gen coupe with the 3.8 - mods were intake header exhaust and a reflash. It made 301 and 280tq.
After the Ny-trex triple threat wet system was added (75 shot), the car made 373 and 384tq. Only supporting mods they had with the nitrous kit were colder plugs and a clutch.

I also went with the Zex kit on my old 350Z I also had the purge kit/ blow down tube /bottle warmer /window switch /NX switch pannel and bottle gauge and was going with the Uprev tune to make sure I was getting enough fuel for the N2O.... Tune is the biggest thing!


DAN

What????

NOS is like hot chick with a STD. You know it will be fun but are afraid of the outcome.

You remind me of this guy I know, Brian Spilner.

^lol WTH

Hahahahahahahaha
