How many have Nitrous

[ QUOTE ]
[ QUOTE ]
why use nitrous????

[/ QUOTE ] [ QUOTE ]
Because just like supercharging it works, period

Fixed it for ya, /forums/images/graemlins/whistling.gif

Nitrous is cheaper than supercharging and doesn't put additional stress on the motor like nitrous does. The biggest reason street driven vehicles run nitrous is that you can shut it off, drive the car every day, and not worry about it. Then ya hit the buttin and go baby go!!

That said, I'd rather be blown on a road vehicle. For a 'wheeler I'd rather have a shot on it.

You lost me there. Are you saying that supercharging doesn't put additional stress on the motor?

I have a supercharged Camaro and I don't care for it, I would rather have nitrous. Much cheaper and easier and on today sports cars, the compression is too high to run much boost with a blower or turbo, that is why many use nitrous. If a motor is built with low compression and the blower setup is done right, I think that they are great, but on stock motors I think nitrous is better.

No....I'm saying it's only temporary. It's not putting stress on the motor ALL the time like a supercharger is. Only when you use the additional cylinder pressure. /forums/images/graemlins/smile.gif

Nitrous sucks

[/ QUOTE ] Actually it cools incoming air and fuel to help squeeze more in. The engine is actually the part that does the sucking.

[/ QUOTE ]
Nope actually it allows the engine to burn more fuel, it might be a little cooler also, but that isent what makes the power /forums/images/graemlins/waytogo.gif

[/ QUOTE ]Actually no. IIRC(I could be wrong though) but nitrous is not flammable at all. All it does is cool the air and fuel so the molecules compress leaving room for more cool fuel and air. It does the same thing a supercharger does in the end which is to stuff more air and fuel in the chambers. BTW, cool air and fuel makes a big difference in power. Hot air and fuel detonates prematurely very easily.
 
well yes your right nitrous by itself isent flamable, but is dose contain quite abit more oxygen, than the air we(and our engine's) breathe, wich means you can put alot more fuel into the cylinder wich equals more power. Adding nitrous actually makes the engine more likley to detonate, wich is why you have to retard the timing so much to run nitrous.
 
this is a quote from the NOS website:
"Nitrous oxide kits make large amounts of horsepower by allowing an engine to burn more fuel. Burning more fuel creates higher cylinder pressures that will push down on the pistons with greater force.

When the nitrous is injected into an engine and the initial combustion takes place, it creates enough heat to separate the nitrous oxide into its two components, nitrogen and oxygen. Once separated, the additional oxygen is then free to react with additional fuel.

To run nitrous successfully and safely, you have to introduce precise amounts of additional fuel with precise amounts of nitrous oxide. All of the extra oxygen provided by the nitrous oxide must have fuel with which to react or you may damage your engine severely. When the amount of nitrous and the amount of supplemental fuel is controlled precisely, your engine can safely and reliably generate exceptional power increases."

I am probably gonna spray a 100 shot and it will handle it just fine. I have a better fuel pump, and window switch and fuel and nitrous gauges. So many people think that nitrous means instant death to a motor, not true, most people that say that have no experience with N2O, they are just repeating what they have heard.

[/ QUOTE ]

Yep.. only one more thing i'd add to your list there...
I wouldn't even think of running nitrous without an adjustable FUEL PRESSURE SAFETY SWITCH!
With injection fuel psi at around 40psi.. id want that safety switch to kill the power or ground to the nitrous/fuel selnoids at 32-35 psi or so.. This is so you don't blow your engine if your fuel pressure cuts out.. your nitrous will be disactivated before you hear the knocking and a rod going through the block..

If i'm at 1/4 of a tank and i get on the gas real hard it will surge for gas for a split second.. If i were squeezing on my engine while this happens.. Instant lean! /forums/images/graemlins/ignore.gif KA BOOM!
My buddy has ran a 100 shot on his tpi'd camaro and it works awsome.. I have future plans to do the same... /forums/images/graemlins/whistling.gif
If i take care of my fuel surging problem.. i'd rather have some boost on it all the time, and the nitrous 'just in case'.

[/ QUOTE ]One mis-conception people have with a Blown motor that it is not stressing the bottom end like people think it is. I can set up my blower for 12# of boost and drive down the road and even off road. The blower is not putting out 12# untill I romp on it.Under normal driving conditions there is very little stress on the motor. Yes at that point When I'am stomping the skinny pedal there is alot of stress on it but that does not last for long. You have to build your motor to compensate for it. The biggest advatage N.O.S has over a Blower is that it is free horespower compared to a blower which comsumes power to produce boost. The bad thing about N.O.S is extreme cylinder pressures. The reply to several p.m's about Horsepower, My motor with 14#s of boost will produce over 1100 H.p on 113 race gas /forums/images/graemlins/thumb.gif

Actually TBI motors run around 14 psi. A lot of people have had problems with FPSS. I have a mechanical fuel gauge that I am going to mount somewhere, maybe on the cowl if I can get it to fit, that I will watch closely. There is always a chance something could go wrong, but with a good fuel pump I believe that I will be alright.
 
Nitrous does cool the intake charge because it is boiling from a liquid to a gas as it is discharged into the engine. This process takes energy, which is why heat is absorbed. The primary reason is boots power, though, is that it is a much denser source of Oxygen than air is. Once the cylinder pressure comes up, the N2O splits into N and O2. You can only burn as much fuel as matches up with the Oxygen you put in. So on the squeeze, you have more gas and O2 in the combustion chamber and less Nitrogen and other inert substances (after all, the displacement of the engine hasn't changed).
 
I was refering to the fuel pressure for my tpi setup.. I'm not familar with tbi.
What are the problems with a FPSS? It seems like you have it adjusted for the psi you want it at... you could bench test it.
Then it either works or it doesnt.. opening the circuit when it drops to that pressure. /forums/images/graemlins/dunno.gif

I would be using nitrous racing up comp hill in the sand dunes... A steep angle, mixed with whoops and bouncing the truck sloshing the fuel all over the place in the tank...
You can have the best fuel pump in the world and if it surges for fuel at the pickup in the tank for just a split second.. /forums/images/graemlins/whistling.gif I know, only hit the juice on a full tank of gas, right.. maybe a hose clamp came loose or you got a crack in your fuel line at the worst possible moment?
My thoughts are, you can't be constantly looking at your fuel psi gauge while hitting the button and if you are, you aren't looking where your driving.
Even if you saw your fuel psi drop on the gauge... it probably only takes a fraction of a second for things to go bad in a hurry with enough nitrous. Hopefully you have quick enough reflexes to let off the button.
When were're talking about blowing your engine here, i'd rather have the safety device built in knowing it'll shut off the nitrous before it leans out...
