computer controlled nitrous, lots of questions

[zspturbo]

so I have been laying in bed for an hour, unable to fall asleep, and some ideas popped into my head. none of this will come true, Its just information I would like to have, and have been unable to aprehend alone.

I want to find out about diffrent companies nitrous kits, specifically computer controlled ones, i.e. something that comes on as a 25 shot at 4k rpm, then ups it to 50 at 4500, and 100 at 5000. Do you know what I mean? the step function things, I dont know the proper name.

anyways, does the venom 1000 kit do that? how about zex wet? and the NX "V-6 GASOLINE EFI DIRECT-PORT"?

Perhaps you don't comprehend...
Anyhoo, shoot an email to JWT. They have a nitrous control system that's popular on Zs (spools the turbos up mucho quicker), and they probably have a quite a few tricks up their sleeves and would be willing to offer you some answers.

I meant aprehend, i.e. obtain :D

anyways, the JWT system looks good for what its meant to do, but it doesnt sound like it does what I want... I want a little nitrous at low rpms, and more and more as rpms climb, eventually reaching a terminal amount, somewhere between 75 and 125. it seems like the jwt system is basically on/off, with on at low rpms, off at high.

I called venom, and they said that what I was looking for was a linear feature, but thats on the VCN 2000, I checked some more, called them back, and that looks nice, but phew, 1200 bucks?

then I called NX, and there was some interesting stuff going on over there, apparently they are working on a new gen of computers, which could be run by palm pilot ( I dont have one :( ) but just the computer is 700, and then the actual nitrous kit he suggested was another 700, so 1400? awwww, mannnnn.

so then I called NOS. they suck, they dont have a system like that. what else do you expect from a company founded on carburation :rolleyes:

Now, I'll be honest, I dont like zex, but this call was just funny. first I get put on hold, then they make me listen to alanis morisset, for 15 minutes then I find out they dont make anything like that. and they have purple everything. and their name is Zex.

I dont like Zex.


so looks like Im gonna be spending plenty of moo-lah on my nitrous, but it should be worth it, because there is absolutely no way Im gonna blow up my engine with a cheapo nitrous kit.

In that case, you're trying to say 'apprehend'. :D :D :D

Good. Make sure it's a nice expensive kit use to blow your motor up!

[zspturbo]

im gonna show you, I'LL SHOW YOU ALL! CURSE THIS CRUEL WORLD WHICH SHUNS ME! I SHUN YOU BACK! SHUN, SHUN! SHUN!

sorry, I've had a little too much coffe today, heeh, *twitch*

[zspturbo]

anyways, what do you guys think about the VCN 2000?

[misnomer]

Correct me if I'm wrong, because all I know about nitrous I learned from watching zilvia.net tech talk. . .

But!

Isn't a "shot" of nitrous all fired at once? Most computer controlled systems fire it at WOT, as it takes time to shoot it, time for it to cool the intake charge (and whatever else it does for you). So, in order to fire just a little at lower rpms, increasing as rpms rise (wouldn't be different shots, 'cause that'd be a lot of nitrous), you would either need to change the pressure through the jet, use some sort of adjustable jet (if they exist), or use several different jets.

That was all me thinking out of my ***, to help your apprehending of information. Here is some more. . .

Furthermore, isn't the most common nitrous system intended to boost lower end power? Or is that just for the purpose of spooling a turbo?

Anyhow, if you are going with nitrous, be sure to build your engine appropriately. Most horror stories you hear about nitrous are because folks try to push it when the engine can't take it.

So are you gonna have the laptop setup next to you? That way, you'll be able to control the nitros flow and stuff, and then, all of a sudden, your computer sends you a warning...DANGER, DANGER, DANGER, and then, this metal plate brakes off and then flies underneath your car!!! Dude, i saw that in The Fast And The Furious!!! It's the coolest thing i have ever seen in my entire life!!! :eek: Hahahahahahahahahahahahahahahahahahahahahahaha

[Jeff240sx]

JWT can do it, I'm sure. Also, your RPM variance isn't wide enough. 500rpms is worthless.
Many companies do make a 2-stage, or even 3-stage nitrous setup. They are simply that. Stage 1 = 100hp, stage 2 =200 or 250. They also usually launch off 100hp, kick up around 2500rpm, and if there is a 3rd stage, it'll happen around 4k. That's mainly dragster shiet though.
Either way, you're gonna spend a grip of cash on nitrous to do what you want... when you could have a turbo for the same price. And, the turbo will ramp up power based on rpm, just like you want. On top of $1400 or so for the kit, $200 remote bottle opener, $200 bottle warmer, $150 purge valve, $200 gauges, and a fill before you should even think about running a N2O-based car. An N2O-supplimented car won't need all that stuff.. but then again, it won't need a dual stage, either.

As someone who has owned a nitrous system in the past, I'm gonna agree with Jeff on this one. Nitrous is quite an expense on every level, no to mention how much stress it puts on your motor. Just save up your money and get a turbo instead of wasting it on a tank of traction killer. I don't think most people realize how difficult it is to control a car shooting any decent sized amount of nitrous. That's all I have to say about that.

well, its 1200 for the kit, dont need a remote opener, I can get a used warmer and nitrous pressure gague from a friend (super cheap), and all I hear is that a purge valve isn't necessary unless you want to do this:

but if Im wrong, please tell me, cause I have only recently started looking into nitrous, and I probably am wrong.

And it wont be nitrous based, I'm not even going to be doing THAT much drag racing, just the occasional all night test and tune at the track, and maby shutting up some retards that I know :D. you know who you are :D

Purge valves aren't just for ricers. They allow you to spray out old nitrous, and the water that gets in the lines, before you spray it into your engine.

Was that picture of the Prelude purging taken in Oakland by any chance?

just a thought - could you manually spray a small small amount into the engine at low revs instead of getting a purge valve? I figure it couldnt really do any damage a small amount at low rpms.

That's totally unrelated to anything. The purge valve releases air and water and some nitrous that's built up in your lines so that when you actually spray, you get pure nitrous in your motor. How would spraying small amounts at low rpms do that?

[Jeff240sx]

It's not a good idea. My friend (KA s14, N2O) has his nozzle stuck in the intake via a rubber grommet, and he pulls the nozzle out, and revs the car to WOT via the throttle body. But, all this requires you to know that you'll race someone, purge the lines, open the bottle, ect. It's a waste of time, and pretty much the reason turbo people buy turbo timers.

The point is that when you "clean the lines out" you're cleaning them out into your motor, so you're solving the problem of delayed delivery of pure nitrous, but you're still shooting water into your engine, and I'm sure you know that's not good news.

this isnt really related to the nitrous question exactly but, arent turbo engines built the same way NO2 engines are?

email me at bovesauto.com i have a vcn-2000 for sale for 600.00 i installed it once but never got the chance to use it

that's a *really* bad idea. low load & rpm mean your engine is turning slowly, so each cylinder has a chance to get a much bigger gulp of the quickly expanding gas before the valve closes. i've heard of V8 guys cracking their blocks that way... and anyway, even the basic NOS dry kit includes a switch that you're supposed to mount next to your throttle body so the system is only active at WOT; so if you install it correctly, you won't be able to do that.

if you're gonna do this piecemeal, do it right. get a purge valve, a remote opener (unless you *really do* wanna be running to the trunk every time... it gets old), a bottle warmer, and have a look at the Jacobs Electronics Nitrous Mastermind; it's the closest thing i know to what you were originally asking about.

I don't think so. I think NO2 engines are built using higher compression ratios, and turbo engines benefit from lower compression ratios to cram more boost to it. Just my $.02

[Red]

Is not NO2 just Air/Fuel in one??... So it does the same thing as a turbo. (kinda) So you can lower your compression and get more in there...

I hear they have nitrous coating for your valves and pistons so they can stand the heat better.... i'm sure this would also work for turbo cars.

I have looked into Nitrous a bunch... I think Turbo 1st. Then if you need any extra help on your powerband you can spray some NO2 in at some key points...
