I have a friend who has n20 on his rotary powered corola. Its a non-turbo motor though. Anyway, his car runs awsome for what it is. Nitrous is not bad for an engine at all, its nitrous and a bad tune that tears **** up. You can spray a couple different ways, full throttle activation which means that when you put your gas pedal to the floor, it clicks a switch beside the linkage on your throttle body that starts the nitrous spray.
Or, you can have a hand held button, and when you want to spray it, push the button.
Nitrous is the easiest to use power adder of them all. Oh, and someone said "Nitrous is for wusses, get the power like a real man", you do realize that n20 makes power the same way a turbo does right? All any power adder, even turbo's, do is add more compression. So, maybe adding more boost is not "adding hp like a real man"?
To end this, in the end its up to you. If you want to pick up some power for a little bit of money, get n20, just make sure its done right.

 

A guy on one of the boards I frequent was wanting N2O for his FD, I advised him not to but if he was really interested to look over here on the rx7 forum for help getting things right. Well he didn't listen to me and so far has used his 50 shot 3 times. Currently his nitrous kit is for sale and his car is in the shop getting the engine rebuilt. Just be very careful if you do decide that you want to spray.

 

i read somewhere that when an engine was running nitrousoxide and the rings failed. . . uh, LETTING OIL PASS BY INTO THE COMBUSTION CHAMBER. . . the injection of n2o into the combustion chamber would cause detonation. the n2o would come in contact with the oil that was stuck on the surface of the piston or wherever it was and detonate a freaking whole into the piston. not very fun if you ask me. everybody knows that a rotary engine injects oil blahblahblah......... its probably not enough to make too much of a difference, but what if you side seal gets all chopped up and you start leaking oil. the "NAWZ" is gonna like that stuff a whole lot. i may have read some bogus info, but it was enough to keep my anti-n2o fire burning. im with dont be a rikki. . . stay away from "the fast and the furious" (whick is possibly the worst car movie ever). its a street car!! i have found that my fd is more exciting on curvy roads than in a straight line. turbo and n2o are a gonna be hard to tune. you need A LOT of fuel. im being way to wordy arent i. i need to stop that. i have a problem with that. is there a forum for wordy posts. hehe.

I think people that hate n20 either don't understand it or are sick of civic guys going nooossss. Can't stand the second myself. N20 is simply 2 parts nitrogen and on part oxygen. The n acts as a buffer, in that injecting pure oxygen would cause and out of control burn, more like an explosion. All nitrous does is get more oxygen into the combustion chamber, as a side effect of going from a liquid at a gas, it is very cold. The cooling effect also raises hp levels, same principle as an intercooler. Problem with n20 is that people add it and think it pure power, wrong. That's like saying you can just turn up the boost and make more power. In both cases all you are adding is more air, which out the fuel to match you run lean and pop. Another problem is it drops all the power in at once, very hard on engine and trans components. If you know what you are going n20 is a great cheap way to make power. Everybody is right it's not a practical way to make power on the street, but for drag racing it's great. I used to have a 100 shot on my old 94 3000gt non turbo. That thing was a slow tank but with when the n20 hit it felt fast (really it was still slow sold it to by and rx7, go me) Once my current rx7 engine goes I plan on putting a 50 shot on the new one. I would rather run 15psi and a 50 shot (probably worth 75 with the cooling effect) , than 20 psi.

Off subject but propane is almost the opposite of n20, propane is like injecting more fuel and getting the cooling effect. With propane you need to add more air, which is why you can raise the boost when running propane.

I could be wrong.

So for who ever asked the question, yes n20 is great. When I asked dave at kdr about it he said rotarys respond very well to n20. just be carful, it easy to think I'll just change the jet and get more hp.

 

One thing to remeber, a nice little shot of NOS can cool down those intake temps..

 

I agree 100%, but you can buy a mastermind and not get the full "hit" at first. You can go from lets say 15hp- to 25hp to 50hp and so on, that way the engine, tranny rear and tires dont get such a sudden jolt of power.

 

N20 is a great way to increase HP if done correctly. However it takes a great deal of knowledge to do this right. and i dont mean knowing how to hook up an N20 system, im talking about fuel delievery,timing etc...so you dont detonate. N20 (like Mkoch1 said) is 2 parts nitrogen 1 part oxygen. The chemical bond splits at 565°F and causes very rich oxygen mixture. The reason N20 makes for such great HP gains is because the oxygen in it is much denser than atmoshperic oxygen (the stuff we breathe). Actually i believe it is somethign like 50% more dense (?) anyways, yes it adds hp and is safe, but ONLY if done CORRECTLY. make sure you got enough fuel and cold *** plugs.

please dont call it NOS. That is a company (Nitrous Oxide Systems). It is called n20 or Nitrous. Thanks.

 

i agree with him
and 1 thing thats funny is when you say nitras is pos or what ever you guys are saying take your 350 hp fd up to the track and race a 315 hp rx7 with 55 shot of nitras and see who takes home the win
and when your crying to ever1 about how he cheated and used nitras ill sit back and laugh and tell you that you cheated when you beat that honda becouse you had a turbo
