Nitrous Questions, Got Experience?

[95auto]

how much nitrous have people run consistently on KA24de's?

i have a 95 auto, that id like to spray, i was thinking a hundred shot would be fine, as i know these motors are strong.
who has done this before, and what kind of results should i look for?

my car is probably about a 16.0 car. bone stock.

Your auto isn't a 16.0 stock. Mine was in the 17's. Race a manual that runs 15.9-16.1 and you'll see.
Also, 75 shots have been run for a while on stock everything. I personally wouldn't do it w/o tuning, but my friend has been doing it for 6 months now.

i will sell you a venom vcn-2000 for 500.00 never used this thing cost me 1295.00

why would u buy something for $1300 and sell for $500?

[ni*2*ss*4*an*0*]

i need money to finish my project and you know you can never get what you paid for something after having it for a year. the kit is in perfect condition..all i did was put it on my car in the winter, and by the time summer came around i took the engine out for a rebuild and never reinstalled the kit..i never even got a chance to use it.

actually, i have beaten 16 second cars on the street, and i run right with a 15.9 truck.

Post a timeslip from a track. It's sad. An auto is an auto is an auto. There should be no difference between your '95 and my old '96.. except a system and another person. But still.. it is so much slower than a 5-speed which are rated at 15.9. If you can hang with a 5-speed s14 (which you won't.. I'll be $20 on it), then I'll shut up.
Also, I would not get a Zex or NOS or Venom kit. They all run extra fuel through your injectors, whereas the Nitrous Express kit takes fuel from your high-pressure fuel line and adds it through the nozzle. If you upgrade the pump, get ignition and cold plugs, I'd be surprised if you couldn't run 100 or 125 on the stock internals.

I am interested in buying your vcn 2000 kit from you if you still want to sell. My email is [email protected]. get ahold of me if you would like.

for some reason, you e-mailed me instead; I don't have a nitrous system for sale...

Hello, I am running a 80 shot of nitrous. I paid about 1,100 for my kit. I'm running it on stock internals with no problems at all! I've had it for about a year now and I don't really like it. I would much rather have a turbo, but that is just my opinion. Hope this helps-

[syco3d]

did you tune it any pinoydrifter? ...or did you just set it up and run...

[pinoydrifter]

No, we have pretty strong engines! I just got a good set of plugs/wires, and made sure my injectors were clean (although they are fairly new), and make sure your fuel system is in good condition! Although if you want to run any more than an 80 shot, you better upgrade your fuel system. And make sure your running a "wet system" (i'm running NOS wet kit) that way it pushes extra fuel with the nitrous. Also you are going to have to upgrade your clutch/flywheel, for they won't last to long! Let me know what you think.
ps- NOS has the best accessories!

[95auto]

okay, fyi, i raced two s14 5 speeds, and both got me by approximately a car to a car and a half.

Wet kits suck. Dry kits are good if its a good type of kit.

Direct port is the bestest

Excuse me? Dry kits suck. How can you (without JWT ecu) add a 75hp nozzle to a car, and instantly go from 155hp to 230hp w/o any additional gas injected somewhere? And don't say that the MAF meters it, because it doesn't. Dry kits suck. Even the $1500 Venom computer kit sucks, becuase it gives a signal to the injectors to fire more fuel, but you're running on stock injectors.
The best N2O system, IMO, is Nitrous Express. It takes fuel from the pressurized fuel line and injects gas through a nozzle next to the n2o nozzle. No instant-lean condition upon activating nitrous, no power limits based on injectors. NX is a wet kit. NOS is a dry kit, and it blows.

Any dry kit that isn't crap uses a fuel line restricter to increase fuel pressure like in bolt on turbo with FPR system. They also either include, or ask you to buy an upgraded fuel pump. And the JWT system which lets you upgrade to bigger injectors is annother example of a good dry set up.

Wet kits don't distribute fuel evenly to all cylinders, unless they are direct port.

So you drive around with a higher fuel pressure than stock, leaving you running very rich for the time that you are not on the bottle. I don't like that. Upgrading injectors is a very expensive thing to do, also.
The NX kit uses the fuel pump to supply the fuel, and with a Walbro hi-pressure 255 L/hr pump, you can max out 72# injectors and still have enough fuel for a 150shot of nitrous via the line.
To go with the "wet kits don't distribute the fuel evenly," well... if that holds true, then dry kits don't distribute the nitrous evenly to the cylinders, which will cause hot spots in cylinders. I'd rather have a 50/50% atomized mix of fuel and nitrous floating through the plenum to distribute kinda evenly than have 100% nitrous floating around to get to the cylinders how they see fit.
Do you understand that last statement? I can't put it any better.. and it sounds funny.

I don't really understand that last part. And the fuel regulation goes on when the nitrous is on, not all the time. It's like a FPR that only goes on and off.

I think in the simplist of terms, he means that a mixture of nitrous and gas (wet) is better then just nitrous(dry).

[DuffMan]

Ok, but I don't see why. 4 fuel injectors can ionize and distribute fuel better than 1 jet.

You said that a wet kit won't get to all the cylinders evenly. The wet kit is nitrous and gas, atomized and mixed in the correct ammounts. If the wet gas/fuel mixture can't get to the cylinders evenly (which they will, based on preportions) then 100% nitrous from a dry kit won't. But the problem is that if 100% nitrous doesn't make it to each cylinder in equal ammounts, since the injectors are providing the "correct" mixture, you will run lean in some cylinders with too much nitrous, and rich in the cylinders that didn't get the nitrous. With a wet kit, the mixture can get to each cylinder differently, and still have the correct ammount of fuel going into the cylinder with it. Wet is better than dry.

So you are trying to tell me that a somewhat ionized liquid is going to disperse as evenly a gas?

If that was so, there would be no multi port fuel injection, just throttle body.

What I'm telling you is that neither one will disperse evenly. But, a pre-mixed fuel and nitrous mixture not dispersing evenly is better for an engine than pure nitrous not dispersing evenly.
N2O not dispersing evenly causes detonation in the cylinder that gets the most nitrous, while the gas-nitrous mixture not dispersing will not do anything harmful, since the mixture has the correct ammount of gas to combust stoichicly.

you can't shoot big HP dry nitrous kits and expect your car to last very long.
My friend tried it on his teggy with a 75 shot and blew the engine after he made a bunch of passes.
Go to shop that runs a lot of cars on laughing gas at the track, ask them for advice. They will probably tell you that a wet shot is a good idea because it doesn't lean your car out like a dry kit.
A guy that actually races his cars told me that you should avoid those venom kits, that they are known to fail...

[SRKperformance]

man what a dreamer your auto will run like high 17s at palmdale, prolly mid 17s at fontana with no air filter, CALI tracks btw, you need to get a cheap nx wet system and run a 75 shot setup with the nx fuel injecotor, hide it under your intake pipe and tape or zip tie the lines behinde the fan shroud or somthing, get creative!

No the gas will, the liquid wont.

what about runnin a 50 shot on my 93 ka with 100,000 miles on it?
would that be safe, advisable or what would i need to do to accomplish running nitrous safely on my car?
