nos on a rotary?
 

hey i recently aquired a 88 rx7 and i was thinking about putting nos on eventually and was curious if nos is a bad idea or not for rotarys i dont know much about them.... i am looking for a good turbo kit tho it has a new motor with all the turbo housings and shit so i'm good for that i know was kinda looking for a big turbo so if you know of any big turbo kits let me know

you really should have searched or FAQed this

and secondly, its nitrous oxide, not NOS. NOS is a brand and using that word will result in some serious flaming

that said, nos is quite possible ,but also quite dangerous, if oyu recall what happens when you encounter a sudden lean condition in a rotary engine (i know someone who blew up two engines with nitrous oxide)

theres a good write up on is somewhere

If you dont do stupid things, you dont have to worry about the stupid things that you've done.

Dont be stupid, make REAL power.

nitrous oxide + tired motor = POOF!

And the average 88 ain't too sturdy.

How is it dangerous? How is it more dangerous then a turbo being on the side of the car?

You're friend who blew up two engines must be retarded. I've built numerous nitrous setups and ALL are ok (all since 04 or later). And I'm not even a good tuner for shit takes. The lean condition can be caused by people hitting fuel cut. OR they do not supply the proper fuel needed for such a setup, when you add more oxygen (air) into a car you need more fuel, its common sense.

Racing is bring what you brought. How is nitrous stupid? Did you get owned by a Cavalier on the bottle? Or a Ls1 powered car? 75% of them are on the bottle btw ;).

And how many guys like Aaron Cake bolt a homebrew turbo setup onto their higher mileage stock engines and have it work out fine with regular spirited driving? A tuned nitrous oxide will be just as effective and will last forever.

Someone PM Scathrat, he knows his shit about nitrous.

To the poster: There isn't anything wrong with nitrous, just tune it properly and you'll be ok :).

i am running nitrous oxide but as a fmic sprayer in july....but i will not spray the motor anytime soon maybe after i am over 400hp on a properly tuned motor that can take an extra 50-75 ponies at a shot i will do

I think what they were trying to say is that one little mistake on NO2 and it is game over for your engine. NO2 on piston motors is just a tad different. I have installed NO2 on both. It is fun, but you should probably look for more power elsewhere. My turbo will never run out of air and I can use it whenever and wherever I want.

If he's asking , he has no idea how to tune it. not that I do or that he's claiming too. just saying man....dangerous stuff.

nitrous oxide is a poor mans blower. That being said in one way at all am I upset that I am using it on my car.

But that being sad though I am not running a rotary though.

Little mistake on N02 and this is coming from a guy named Boost Maniac? Do you have a turbocharged car? Any lean condition on a car can cause it to fuck up. Little mistakes = bad tuning.

More power elsewhere? For 1k you add 50-75 HP and a fantastic powerband.

Run out of air? O-k?

If he's asking he could have it installed at a shop or learn to do it himself. The forum to ME is a learning tool, maybe he's trying to learn by asking.

Have you had experience with nitrous EVER? On a rotary?

Dangerous is subjective, people here install Pineapple racing sleeves after they destroyed NUMEROUS engines by falling into the engine. At least nitrous has been around forever and has alot of knowledgable tuners behind it. If anything you should worry about the drivetrain. And people still install them for 2-3HP :rolleyes:.

Poor mans? My friends on this forum use it on his 10 second FC (DigitalSolo) and my other his 500HP Vette ;) (PianoProdigy). Both of them have put alot of money in their cars.

The sleeves fall off cause people are stupid when they put them on and dont rough up the surface for good adhesion.

I agree with you about the nitrous tho, its probably about as dangerous as the same amount of boost off a turbo.

Which would be more explosive if the car backfires or something and ignites the intake manifold?

You win jager! You win! everyone take a deep breath.

lol

There is nothing any more wrong with using nitrous than there is with using a turbo or a supercharger. All of them can blow up your engine if it isn't tuned properly and all of them can make you go fast if tuned properly.

my point was that unlike in a piston engine, if mess up nitrous even slightly on a rotary, you can have a nasty detonation and kiss your apex seals good-bye

that said, and if youre really serious about it, nitrous is a perfectly viable option, but its must be carefully and meticulously done

N2o is not a bad idea in small doses.If you are going to turbo your car you need to decide whether or not you are going to be driving this car daily or just racing the piss out of it.N2o is a great power adder but you need to research the effects it will have on your turbo setup.You can use it as a way to help spool the turbo at low RPMs or you can use it as a top end power adder.If you are new to N2o + boost I would recommend finding out how each is going to affect your air fuel ratios and accomodate appropriately.Start with basic mods to improve your fuel and airflow.A fuel cut defencer is highly recommended!

What I ment by that is compare a n2o set compared to a say roots style blower or a procharger. And I know I have a FC 388 sbc that will be running 11's this summer to (if I get it out in time) and it isn't cheap. Power = money I know.

ok ok damn thanks but geeze i'm pretty new to rotary's so i didn't know if it would be more dangerous than a piston engine geeze. now about the big turbo question? anyone know of big turbo kits for it?

you have to know what you are doing with nitrous. When to spray it. As in, at what rpms, what pressure, how long, and how much. If you know all this then you should be fine.

Hello dude. I have an 86 gxl that I bought not too long ago. It has 137000 miles on it. I have put a Nitrous Express kit on it. I am just running a 50hp shot. My only other mod is a racingbeat downpipe and presilencer combo with smog removed. I have went thru about 2 10lb bottles and have not had any problems out of it. The car runs as good as it did before I ever sprayed it. I did not have it tuned or anything (i plan to very shortly) , just hooked up the kit and went with it. I did check my compression before hooking the kit up, and I was at 110 on all 3 sides on both rotors. It seems to run better after spraying it, I guess it is burning off some carbon.
Hope this helps

Go re-read what I said and then shut up.

I would never recommend it on a turbo RX-7, imagine the boost creep!

Plus I have no experience with nitrous on a turbo RX :(.

not to sound like a tool.. but if you want "nawzzzz" on a rotary, buy a honda or a V8ed 7
IMHO N20 is a good performance enhancer... it makes the O2 burn faster and hotter... but when taking an engine that naturaly runs hotter and then push it further... it just a bad idea.

if youve got a shop and you dont mind rebuilding engines offten... why not? but performance wise why not just run a larger turbo with supporting mods? Turbos are bad enough when it comes to longivity...

out the damn n2o on if the engine blows learn from your mistakes and rebuild the engine. NIKE man just fuckin do it.
