well, we all know the pro's for NOS in a rotary engine....but is it safe...i need alot of input for this one...anyways, thanks boys

SirRX7

NOS should work as well as the other brands. Pros and cons should be similar.

N2O or Nitrous Oxide, not NOS
like calling all rotaries a 13B-REW.

www.fc3s.org has some stuff about different setups of nitrous oxide. Both wet and dry systems

sublimeracing

As long as you don't over do it. A well tuned/running rx7 can take a 70-100 shot, with minimal wear to the engine. I've read that 13b's as classified with 6cyl. engines when it comes to NOS. The kits they sell are vehicle specific are the best because they are set up to not kill your engine...

Josepi

Beat me to it.

Pro: HP, cheap.
Con: Need a good fuel setup to make sure you don't lean out. Refer to the link that Node posted.

Actually, I also remembered that NOS was N2O, but after checking the table, N has +3, +3,5, +4 and +5, while O has a +2 or +3 oxidization states, with 3 and 4 electrons in the outer 2p orbit. So their most common molecule should be N2O3...dont remember so...

Just out of curiousity, what are you talking about. Nitrous oxide is N20, not N2O3.

He's talking about molecular make up, but I don't know exactly what he's talking about.

Nitrous oxide is called N20 because it's TWO PARTS NITROGEN, AND ONE PART OXYGEN. If it was N203, it would be called nitrous trioxide. The whole Oxide part means it is a binary compound containing only one oxygen molecule.

Gimpdiggity

Sorry, forgot about the question at hand....

Pro of N2O - It makes your car fast.
Con of N20 - You have to refill the bottle when it's empty
Pro of N20 - You only have to use it when you want to.
Con of N20 - If two Asian guys on motorcycles shoot at your car while you're driving around with Dominic Torreto, your car will blow up...


But yes, check out the link that Node gave, that's where I found the best info about Nitrous Oxide on a rotary.

Def get a wet system. My '89 vert rock with n230 or no5 or n20 or something. What ever it is the car is fast.

thank you.. i cant stand when people call it NOS...it sounds so ignorant like "i-just-came-out-of-fast-and-the-furious-ish" i dont know if other companies make nitrous setups for the rx7's, but in my opinion NOS is the most low tech nitrous system out there. i would get a ZEX kit if there is one available for it. thats just me tho.

Nitrous:

Pros:

1.Easy
2.Cheap
3.Makes your car alot faster

Cons:

1.Most people don't know what other mods to do to make it safe
2. " " " " " " " " " " " " "
3.See above

NOS #5132wet is a nice system, set at 3/4 throtttle and 4k RPM it is very easy to install and fun to drive. I also setup a turn off switch to kill the system during daily driving, to easy to get on it sometimes

fastrotaries

RX7.com recommends Nitrous Express and so would i. those guys are dedicated to their work.........I'D HATE TO **** ANY ONE OFF BUT.... The industry has been referring to N2O as NOS for over 25 years. It's a slang term. So for all of you Engineer, PhD types on this forum, quit having a cow everytime someone calls it that. Yes - you know it's molecular structure, i'm so happy for you. Write it down, and give it to mom, so she can put it on the refrigerator

amemiya

Thats just because it is a house hold name like xerox. Its just easier.

Yelow RX-7

if it was me, i would go with Venom...

DC350

I dont really care about the molecular make up, i just wanted to know if NITROUS OXIDE f*ks over the rotary engines!!!! and is it safe over the long term, or what exactly happens?

T2monster

I hate to bust alot of bubbles, but......you have to be more precise in using "NOS" to mean "Nitrous Oxide" in general, mainly b/c
NOS, Inc. is the largest manufacturer (not for very much longer) of nitrous oxide kits in the world and have been building systems since the late 60's. Personally, i think NOS brand kits are extremely well designed, mainly b/c they will not sell a dry system w/ more N2O than a stock feedback EFI system or carb. jet kit can accomodate for, and they sell wet kits that installed correctly are designed to hang the A/F ratio in a certain spot on the scale, a safe spot.
No, N2O will not make you spit apex seals, IF INSTALLED CORRECTLY, with additional good grade fuel. It is no harder on a rotary engine than intercooled turbocharging; they're both all a/b cylinder pressure.

Would N2O be easier on an engine because it is not used all the time, true that your not always running at max boost with turbos, but they are always forcing air into the engine. So wouldnt turbos be harder on the engine?

Actually Oxygen can have an oxidation state of -2. If I remember correctly in order for a element to be at the back half of a compound (i.e. the oxygen in N2O) it has to have a negative oxidation state, so with nitrogen having an oxidation state of +4, and oxygen having an oxidation state of -2, N20 would be able to occur. I think?? Correct me if I am wrong.

RX-7Impreza

NOS is NO5 that is why it looks like NOs on the bottle. the 5 is in subscript like in chemical equations. just clarifying. the reason Nitrous oxide is used is due to the large amount of oxygen it releases into the mixture. thus..... NO5

Justin

PlayinW/Wankel

That would make more sence because oxygen sometimes carries a 1- oxidation state, making a highly reactive element, that is also why it is used in oxy/acetalyne torches to increase the intensity of the flame. Metal shop and Chemistry all coming together

Gimpdiggity

NOS is NOT NO5...it's N2O. The numbers DON'T refer to the charge in the system, they refer to the NUMBER of molecules present in the compound.

Nitrous oxide is N2O, because it is 2 PARTS Nitrogen, and 1 PART oxygen...

It's BASIC chemistry, and not that difficult to follow.

http://www.webelements.com/webelemen...-10024972.html

Go there, it will show you that nitrous oxide is n2o. The CLOSEST compopund to NO5 is N2O5, which is dinitrogen pentoxide...hardly the same thing.

fastrotaries

The Vemon kit is nice just too pricey for me when i can do the same thing for less. Just remember one thing. It's not the N2O that makes the power. It's the fuel. Running Nitrous in your motor will only allow you the capability of running more fuel, thus the power increase. So without proper tunning you're pissing into the wind. Hence why motors go when under the influence of the bottle.

THIS THREAD IS NOT ABOUT THE MOLECULAR MAKEUP I WAS WONDERING IF IT IS BAD FOR THE ENGINE OR WHAT MAKES IT MESS UP! I DONT CARE ABOUT THE N20 AND THE N05, CHRIST
