Nitrious on the Alpha

[WytchDctr]

Like I said even if YOU are getting away with it, dont tell others its 100% reliable or even a good idea, lol. That would/could/will gernade most engines to double there output with crap for supporting mods.

Im on the bottle too, only a 35 shot though

For the record I have never said it is reliable, safe, or advised. I just said I am doing it and I have been through 5 bottles now and still no troubles. I'm sure at some point I will encounter issues but so far so good. When I had a wideband hooked up for testing it ran rich while spraying. A little rich when not aswell. I think thats the RAM air though. The ARC-1 will fix that.

I hear you though Doc, and I have never said it's reliable. Just fun.

I know Grim has his doubts but Fins seen it. I run a 110 on my LC2. Usually just at the track. Been through 4 bottles so far at the track plus one for tuning. I know the Alpha can handle it. I'm sure...

Not to start an old thread but I'm spraying a 110 in my pretty much stock LC2 and i have been for about 3-4 months now and it still runs great

newbs are going to read that and think. I should do this.

Regardless of how much Hp shot the Alpha can take isnt it relevent to feul pressure? so on a stock Accent? how much HP shot?

On a Stock accent with increased Feul Pressure?

And what part does a Walbro 255 play in this game?

Okay...

Think of Nitrous as a temporary turbo. A 35cc shot of Nitrous is roughly the equivlant of that much of air. In order for you to compensate for that much more psi, you'll have to tune the extra air into the equation.

F&F fans before, Nitrous is not a combustable gas. It retards detonation so you can pump more fuel and air into the same piston w/out premature detonation, which means a little added umph.

A Walbro 255lp pump isn't really needed for small bursts of No2. With a stock fuel pump, you should be able to do under 50cc's and be able to tune it out. Its not an HP shot Asperllia, it's a CC meaning the volume of gas injected into the intake. Fuel pressure is a direct corelation with the amount of gas, so fuel pressure would also increase.

All in all, a small amount of ntirous used occationally should be alright on stock internals. You would have to have the right programing to ensure the right fuel/air combination at higher levels, but that isn't really recommended with stock internals. Upgrade, or add a turbo. It's cheaper in the long run.

That’s not how I understand it. I know its not combustible on its own but it is an oxidizer. Its 33% o2 instead of the normal atmospheres 21%. (the N20 breaks down during atomization). Allowing you to add more fuel without needing use a compressor to push more air in, it’s a chemical turbo. Ha. That and the fact that when it changes from liquid to gas state it gets really freaking cold dropping the intake charge down adding some power. Ive heard estimates of 20% of the “shot” increase comes from that drop alone. BTW its not a 35cc shot. The shot rating is suppose to show the amount of horsepower you are going to make with that amount of nitrous and fuel (if it really is 1hp per cc over some amount of time ill take that back, lol)

Throttle in a Bottle

Thats the basics of No2. You're right that it is denser than Air, and I tottally forgot to add that. But it does retard premature detonation. When used in turbo apps, you can literally blow up your intake mani because it pools up.

I always though tthat the 110 and whatnot figures were from cc's of nitrous introduced into the intake. There is a minimum horsepower that SHOULD be made from it, but I thought that it was just a correlation.

Retard Detonation: I have heard that the 1000Bhp Skyline's only use nos when the car Begins to Ping....

[Asian_907]

They use Nitrous on drag racers for the same reason...

It cools intake temperatures and helps to retard detonation. Kinda nifty eh?
