Odd ? about N2O

[Chris Wood]

I was wondering if any nitrous company makes a "digital N2O injection system"? Is there one on the market that "fires" each N2O and fuel nozzle in the same sequence as the downstroke of that cylinder.

Wouldn't this greatly improve efficiency, and lessen the chance of a nitrous backfire.

If it was a true digital system, the tuneability would be incredible, no more lean cylinders etc.

What do you guys think?

No, I don't think there is anyhting like that on the market.

In theory, that would sound great, but the precise tuning of it would be terrible. I don't think the solonoids would hold up to that type of abuse, especially at those high RPM's. I doubt that each solonoid would even open & close fast enough to keep up either. You would need 16 REALLY HEAVY DUTY solonoids to do that. That means 16 totally different systems & components. It's probably impossible, but who knows. I personally wouldn't experiment with it, LOL!

The best & closest thing to that is a fogger system plumbed w/ seperate jet levels for each cylinder. This is done on pro stock type racers with hours & hours on the dyno and a dozen motors to spare.

Solenoids, we don't need no stinkin solenoids!

What I was thinking of was something along the same lines as a fuel injector for the n2o.

You'd DEFINITLY need solonoids!
Your injector has a normal capacity to handle the fuel pressure at about 45psi. Nitrous has a normal operating pressure of around 1000psi. Not to mention it has to be able to handle the below zero temperatures & must be teflon coated.

SOLONOIDS ARE A MUST!

Captian, did you see the new nitrous set up for the mod motor stangs? The nitrous is injected in the same port the injector sits in, the injector looks like it mounts on the nitrous like and the whole assembly mounts to the intake. I'd like to find a picture of it for you. I don't know what the deal with it is, but it might be something to look at. It could somehow be what this guy is hinting at. I don't know if it is or isn't computer controlled.

I just went to the NOS site & checked it out. It looks like a clean system w/ tons of jetting capabilities. Basically, they took their Fogger injection system & matted it to a fuel injected intake. The best part of this kit is that you don't have to drill & tap the fogger nozzles into your expensive intake. This saves tons of time & costly mistakes. You can also jet each induvidual cylinder seperatly for rich/lean conditions. It's not the digital system you were referring to, but I like the concept.
Their fogger system is quite pricey as it is, so I don't think this is an outrageous price, especially for the first company to come out with it. Others will most likely copy it (or have a close spinoff) & be out on the market shortly.
I would invest in it if I were starting a fuel injected race project. Well worth the dough!
Kudos to NOS!

Why do you need solenoids?

Where's Curt when you need him?

Anyway, I know my old 6.9L diesel had diesel injectors, and the fuel pressure on a diesel is incredible. A diesel has a fuel "distributor" instead of a spark distributor, in a gas engine. I don't know how the new power-strokes are timed (injectors firing), but this same type of technology could be adapted to a n2o system.

I beleive it can be done!

Anything can be done with enough $$$$$$ and time. Of course if you have enough $$$ you would have the time..

 

[CAPTAIN]

Anything can be done, but to what extent?
You mean to tell me that the fuel pressure on a turbo diesel is around 1000psi?! The actual fuel pressure is nowhere near that, but the injector impulse is around 1000. There isn't much volume coming out of that though, so I don't think this would hold up for a nitrous application. The nitrous will eat that injector up, even if it was teflon coated and prepped for nitrous use. There is NO WAY the injector could withstand the constant pressure of the nitrous in the feed line, around 1000psi. This is why a solonoid is used. It's not a question of actual injector impulse, it's a matter of strength. And if it could withstand that pressure, could it hold up to opening & closing at an enormus amount of speed for each cylinder firing? I SERIOUSLY doubt it, but yes......It COULD be done! Anything CAN be done with time & money to play with.

Maybey my original post was misleading, I wasn't saying that I wanted to make this set-up. I was merely speculating that I feel that this type of system is the next step in N2O technology. Obviously, the first place we will see it is at the track, not on the shelf.

I just thought that it would be a very tuneable system, and several of the problems associated with current nitro systems woud be eliminated (lean cylinders, nitro backfires, etc.).

I understand we were speaking theoretically. Sorry if I came off like a *****, I wasn't trying to be. I was just trying to discuss the possibilties.
