need some HP
 

i need more power! i have an 86 n/a and i was wondering maybe i could drop a turbo in or something, anybody know a cheap way to bring up the hp?

You could try the 200mph leaf blower idea... Other than that, anything that adds serious HP in an N/A is going to cost lots of $$$.

NOS Nitrous #5132 kit - $499 (Summit Racing)

Install information is on my site:

www.fc3s.org ---> How-To's --> NOS (wet system)

That is a 50hp mod. By changing out the jets, you can make it 100hp upgrade without any other mods.

You seem like someone who could answer this question for me:

How does NOS actually work? Like what's the difference between a wet/dry system? How long does the 50HP+ spurt of NOS last? Seconds? Minutes? Do you need to upgrade the fuel system for a 100HP shot of NOS, or does the car run completely on NOS after you activate it? How many "shots" are in a bottle of NOS, and how much is it usually to refill the tank? What if you need to brake or stop after you've activated the NOS?

Hey, if you could answer some of those questions, that would be GREAT. I don't know anything about NOS, and hopefully you can clue me in. Many thanks.

Dave

I can surely try :)



NOS, or Nitrous Oxide correctly stated, is comprised of 2 parts nitrogen and one part oxygen (36% oxygen by weight). When the nitrous oxide is heated to approximately 572 F (on compression stroke), it breaks down and release extra oxygen, However, it is not this oxygen alone which creates additional power, but the ability of this oxygen to burn more fuel. By burning more fuel, higher combustion pressures are created and this is where most of the additional power is realized. Secondly, as pressurized nitrous oxide is injected into the intake manifold, it changes from a liquid to a gas (boils). This boiling affect reduces the temperature of the nitrous to -127 F. This "cooling affect" in turn significantly reduces intake charge temperatures by approximately 60-75 Degrees F. This also helps create additional power. A general rule of thumb: For every 10 Degrees F. reduction in intake charge temperature, a 1% increase in power will be realized. Example: A 350 HP engine with an intake temperature drop of 70 Degrees F, would gain approximately 25 HP on the cooling affect alone. The third point, the nitrogen that was also released during the compression performs an important role. Nitrogen acts to "buffer or dampen" the increased cylinder pressures leading to a controlled combustion process.

I got that from a webpage :) Faster than typing it all out!

---

Wet systems use the injection of fuel with the NOS into the fogger nozzle. Dry systems just inject NOS through the fogger. Typically a dry system needs to be tuned by someone, where as the wet system adds that extra security of more fuel to prevent killing your engine.

---

The shot lasts as long as you have your foot floored. As long as the throttle is at 100%, then the NOS is on if you have the system turned ON. When you release the pedal, the NOS cuts off.


If you are running a wet system, then that is as far as I would go without fuel upgrades. With a dry system, I would not go above 50 without an upgraded fuel system. The car runs as it always does with the NOS on, it is just injecting NOS while it runs normally. The NOS is what makes the additional HP gains.

How many "shots" are in a bottle of NOS, and how much is it usually to refill the tank?

---

In a 50 shot wet system, about 20-25 full 1st, 2nd, 3rd, 4th gear pulls. In other words, 20-25 1/4 mile runs. NOS usually costs between $1.50 and $4 a pound. Bottles come as 10lb versions, but you can buy other bottles to suit your needs.

What if you need to brake or stop after you've activated the NOS?

---

Just let off the throttle and brake as usual. Doenshift if necessary.

hey good stuff man, that helped me out alot! my buddy has a purple haze NOS system in his celica, he said he'd sell it to me for 200$ seeing as his car was mostly totalled by vandals. think thats worth it?
and the real question, i visited the fc3s site and i just wanna know, in "project 86" what are they doing to the tail lights? it looks supe cool, ive been looking for tail light covers and whatever they are doing looks slick! let me know
thanks

hey
 

I will buy it next week. Give me his number if you decide to bail out of it.

that website makes me nervous. first off, i thought that nitrous was NO2, which would mean two parts oxygen, one part nitrogen, instead of the other way around. since N's atomic weight is 14 and O's is 16, that would mean that O is 70% of the weight. now, nitrous oxide even tells me that it is O2 because oxide is O2 with an oxidation number of -1, although i don't know what N is.

correct me if i'm wrong guys, but this is what i thought it was

As an alternative to adding power, you may wanna try making the car lighter.. going with the lotus elise theory.....

Oh no, Ive gone cross eyed.

NO!

Nitrous oxide is N2O. Two parts nitrogen!!! It is stored in a liquid form. When pressure is released, it turns to a gas and expands RAPIDLY. The main function of N2O in an engine is to burn more fuel in a lesser amount of time. That extra atom of oxygen does just that. the NITROGEN is what can imbed itself into the metal and slowly deteriorate it. If you use too much N2O, the unused oxygen will super-rust (yes) the internals. Imagine RUST inside your engine. there is a lot of shit to go wrong. The energy required to break the bonds between the 3 atoms requires masive amounts of heat (it takes this heat from its environment). That's why N2O will ALSO lower the intake temperature. This RAPID cooling and heating of the internals can also fuck up an engine! :eek: That is why you hear stories of kids sniffing N20 and freezing their trachea or lungs and dying.

BOOYA!

Sounds like FC3S.org KNOW wtf he's talking about...

Ya dumbasses pull it straight from the can. Same with any compressed gas. That's why smart people use balloons. Or used to :D

Uh....

These are mutually exclusive terms.

Smart people + inhalants = no compute.

n20=laughing gas=used at dentists :-D
i think its the same thing. Could be wrong, but dunno

Yup. You get it in a mix with normal air, by no means is the body meant to be taking breaths without any oxygen. That's when lightheadedness and such kicks in. I've done tons of shit, never anything that would do true harm to myself. Ya, I'll do 135 in the country, but I won't do 135 in traffic....BTW i quit most everything bad i've done...smoking most recently...

I highly suggest that you do not use N2O for inhaling. The stuff they use in doctros and dentists office is medical grade, and the stuff they use for cars is a lot stronger and fatal.

The car-grade N20 also has trace amounts of sulfer to deter inhaling. it will taste horrible, and probably wont feel nearly as good as pure N20.

I have a lot of mods on my FC, and I was thinking about NOS. How much of a shot could I go before I start really messing things up. The engine is recently rebuilt(8K miles), and I have a very long warranty because the company I got the engine from messed it up and I had to fix it. They tried to make me happy by giving me a very long warranty.:D I was thinking about a 100 shot. Can I do that on 93 octane pump gas?

Cheapest way to get mucho horsepower is NOS kit. It's cool if you're looking for mostly straight line performance, but there's also the supercharger route and also the turbo addon route. I'm hesitant on the NOS idea just because of my own fears about NOS. Superchargers are extremely expensive albeit reliable. So I'm decided to go the turbo route. VtekEater is currently making a kit for a good price, just search for his name and you'll get his email. It's arriving int he mail within the next two weeks so I'll let you guys know how it turns out after it's finished!

Peace,
AJ ^_^

how much does a turbo addon run for a N/A
and what more than engine ecu and turbo and piping from tII engine to swap into N/A with blown engine would It need to work nicely

*edit*
Oh yeah is there any sort of reliability difference with using NOS on a charged (super or turbo) and a N/A engine. Like does it hurt the turbo or anything?

I dont' see why it NOS would be a problem with turbo since the turbo is mountain on the exhaust manifold and NOS is hooked up to the intake piping. But superchargers is another story. I have no clue if superchargers would be ok. i assume it should but then again, I've never done it so I don't know! As for the turbo kit, it'll cost around 1200USD with installation. VtekEater will know more information about this so contact him about it. Swapping a TII engine COULD cost more or less depending on if you do it yourself and what engine you get. Jspec is probably the cheapest and it would run about 1000USD to install everything yourself. And this is after getting the other parts for it like ECU, etc.. Well, good luck with whatever route you choose! OH BTW: hooking up NOS is extremely easy. The only hard part is probably the wiring and even that wasn't too difficult. Just a few splices here and there.

Peace,
AJ ^_^

Check out www.fc3s.org for more information. They have a really good description and writeup on how to install NOS either wet OR dry.

damnit i just want a project car. tII or GTU/GTUs (89+ preferrably) with no/blown engine and a nice interior for $600-$1300 or so, just pop a tII engine in it and some simple mods and be off !@$#!@$ great way to learn about rotary engines with some hands on experience. DAMN ME BEING BROKE lol
So far for this I'm lookin at books at the library (which suck) and I'm gonna get a newer (mid 80's-90's) RX-7 book and repair manual and that one video, hayes i think. Anywho that should help me do this :-D
