Who's running nitrous on their RB?

[jdmser]

Just want to know if anybody is running nitrous on their RB. What kind of system are you using and what kind of results have you been getting?

[Joe]

why?

its turbo.

why add a crappy poweradder when you have a good one.

[Andrew85cm]

I would have to agree with Kamin on this one. Why add nitrous to your motor when you have a turbo. Add more boost if you want or swap that ****ty stock turbo and get you a new one thats bigger and will produce the kind of hp you want. Turbo is the best form of Forced induction in my opinion. You dont need anything else.

[krayton]

ill probably be adding it soon. for some dyno runs and time slips.

i recall a gtst on the aussie boards running high 11s or low 12s in near stock form with just nitro.

i dont think its a bad power adder just damn expensive. (refills) but ive been seeing a few people selling their kits for a good price, so its tempting.

id be tempted to use it on the track, but id just want some different gear ratios.

come on joe. pir...coming around the oval at about 125+ if we change our final gear and hit a small button coming out of the last turn

plus now with aem its gonna make it cake to tune it

EDIT: dug it up for you guys:

it really dpeends what type of car you are trying to build. nitrous is good for the track/sleeper street. i don't think its a bad idea... nitrous and turbo complement each other very well. why not dual power adder if you can?

since you can consider nitrous a "bolt on", its less labor intensive than porting a head for example. if you've reached the max flow potential of your head, why not send something more potent through it (aka nitrous) so you can achieve more gains?

you can't always just slap on a bigger turbo and expect more power... not arguing w/ anyone, just saying its not a bad way to go. i would consider it for drag applications

im perfectley fine at ~105 on the bank at PIR knowing my engine isnt gonna pop

you know now that i think about it, i dont even know if NASA allows Nitrous on track.

"no no justin. thats co2 for my intercooler sprayer"

[Reignman]

If you have a larger turbo nitrous will help with the spool up. Other then that I wouldnt use too much nitrous on a turbo motor unless it was tuned safely for it.

[SeVa-S13]

Doing anything without a safely tuned engine is retarded, turbo, nitrous, whatever.

Why run nitrous on a turbo engine? Well, more power is nice, dunno bout you. Cooler intake charge temps. Better powerband for the same power than a ludicrously large turbo is also handy. But nitrous is bad, right guys? It'll blow up your car like in F&F and always destroys engines right? Just like 3" exhausts are too big for smaller engines, and backpressure is needed? Hahahaha...

nitrous is bad on an already boosted car because its not a bolt on affair. to do it properly and safley you need to tune FOR the nitrous, and without the nitrous. so thats 2x the tuning right there.

better turbo > nitrous+turbo car

[krayton]

^ better turbos for our cars can cost a lot of money though.

my next step off the top of my head would be like a t66 or something. thats gonna hit me with a bigger wastegate, custom manifold alone.

i think if your looking for anther 100hp to take on easily, that would be the way to go.(nitro)

[Carl H]

naaaawwwssssss is speed for retards......lol.unless you have a t88 strapped to the side of the motor forget it, like seva said it will be a pain to get it to work right without popping a motor.......a bigger turbo is a better way to make power, more expensive yes but more reliable as well.

[krayton]

im gonna disagree a bit.

a lot of people have it stuck in their head that nos is hard to tune.

strapping a t88 and tuning it can be reliable, but so can shooting 150shot of nitro.

both need tuning to run right and both can be reliable with tuning.

so lets just agree that tuning is the key here.

[TheOne]

hey 03 mustang cobra owners use 50-100 shots with either the stock eaton or the kennebell superchargers and it seems easy to tune for'em....should be almost as easy for a turbo.

also a 50 shot isn't so bad for those days when you just feel like shotin it, sideffect bein cooler air charge.

[onefastrb26]

If you have a standalone like the AEM, you can SAFELY tune teh shot.

Nitrous is perfect if installed and tuned correctly. Cooler air charge and help with spoolup. Just make sure it is a wet shot, it is running safe air-fuel, and adjust your timing accordingly.

Ona fully built engine, with aT88H turbo, and AEM EMS , I would use nitrous in a heartbeat.

Oh, and you DO NOT NEED 2 tuning files, just one file with the AEM ...

[krayton]

^yeah joe. its got a special NOS button.

you would know this if you spent more time over here!

[DriftingisLame]

why?

its turbo.

why add a crappy poweradder when you have a good one.

Okay, I am not meaning to be mean here.. but this is absolutely ridiculous. It seems as though your just being incredibly bias in this situation (as in others, but thats a different story..). What do you think drag cars use to spool their giant turbo's? Do you think they just wait until 5k when the motor would push enough exhaust gas to efficiently spool a giant turbo? No.. a lot of serious drag cars have resorted to the happy gas. My buddy rob for example has a KA-T, fully built motor from the oil pan up, running a pt-67. He has a nitrous kit that will be there purely to spool his huge turbo (roughly 125 shot).

Nitrous is a very good option for some people on certain applications, with the proper tune of course..

I'm sorry for venting but I'm not going to just listen to an RB *mod* say that nitrous is a bad idea or a "crappy poweradder". come on....

I definitely agree. While I'm not sure if I would use nitrous, it is still useful and shouldn't be discounted that quickly from use on an RB.

[klattr1]

some people dont use nitrous cuz they are scared of it (not understanding the properties of it, how to install it properly, how to safely use it and tune for it, and are predetermined a nitrous backfire will happen cuz they see a video on the internet).

certain applications can benefit from it and do well with it. its all about getting comfortable with your car and motor. there's plenty of SRT4 guys running stock turbo and 100-120 shot and running 12.0s at 119.

[Carl H]

ok i was a bit hasty in my opinion about nitrous on a turbo motor, but yeah it can be done right with awesome results.however i would like to expend all other routes to spooling the turbo faster than nitrous........i still have yet to dial in my cams, play with my timing map more and fuel to add.........and even then i have a water injection system that i can throw on for more cooling....no2 isnt for everyone, i know i cant afford to fill a bottle every week.

[Sil240]

I'm not a fan of nitrous but i think i would use it, cause i definetly dont want a huge turbo but to get some more power would be nicew/o huge LAG

[Wulfgang]

N2O. NO2 is poisonous, corrosive, and very stinky. N2O is just funny and fast.

IMHO the ONLY good reasons to not use nitrous are 1) you are doing road racing and 2) you cannot afford the refills. Other than that, it's perfect. It's like Red Bull for your RB. Adds power AND sex appeal. And when you unhook the bottle you can get a little high on the fumes.

[SeVa-S13]

And when you unhook the bottle you can get a little high on the fumes.

Somewhat comical, but untrue. Most automotive-use N2O has a small amount of poison so it can't be used to get high, sorry. =\

Oh, and Carl, I was being sarcastic and arguing the pro-nitrous side. How else do you expect me to keep up with your big budget 20 with my moderate budget build?

[Wulfgang]

Yeaaah... but who buys automotive grade? The industrial stuff is much cheaper (and sniffable). And if you have a nice welding shop in town (like we do here), you can take out a lease on the bottle and never ever pay rental fees.

Still, the refills are too expensive for me, so I will stick with turbos.

I had a bottle in my Nova that my friend huffed. It doesn't contain poison. It has sulfur in it and is suppose to taste horrible.

[Andrew85cm]

I'm sorry but your friend is a ****in retard if he huffs on nitrous. Car grade nitrous contains sulfur dioxide which if you know anything in any subject that is some very bad stuff and is definately harmful to your lungs. I wouldn't touch that crap. Get some whippets if you want to huf on n2o. Otherwise it is a very very bad idea. Also in car grade it has other trace amounts of chemicals that are generally okay for an engine to burn but that doesnt mean it belongs in your lungs. Bad call man bad call.~ANDREW~

[s14 2510's]

Nitrous is for cars with Big turbos. I dont need that crap. The way I am building my swap I will have power all the time.

[krayton]

NAWZZZ is for more power. you dont use it just to spool up big turbos. you can use it for top end when you have small turbo/turbos. and you can use it when you have power all the time.

[Wulfgang]

Krayton, not to be too picky, but "nitro" usually means nitromethane.

[240Z TwinTurbo]

Speaking from first hand experience nitrous can be very beneficial for drag race applications on turbocharged cars. I routinely ran 125shot on my twinturbo 240Z to get the car up to boost instantly. At 28psi my car dynoed 451hp/509ft-lbs @wheels, with 17psi and 125shot it went 10.6@134 which worked out to ~490hp@wheels.

I could literally foot brake the car at 2400rpm(powerglide transmission) making not boost and cut 1.65 60ft. Why? Because the nitrous gave me instant 125hp and instant boost. Some stick cars that run large turbo's have trouble launching because they bog due to excessive turbo lag. Just adding a 50shot will cure this in many cases.

I never really used the nitrous on the street, only for track use. I believe it has its place and I will be using it on my new setup, RB26 power 240sx. To each his own.

BTW, as far as tuning nitrous. Just tune you car to the desired AFR without the nitrous. Perhaps 12:1 AFR. Then jet the nitrous until you again reach the desired 12:1 AFR. You have to tune them seperately and you need to tune off the nitrous first.
