Has anyone done one of these kits there self?
I was thinking of ordering the bar and just using a NOS purge kit and some paintball c02 bottles. What do you think?

Thanks Channon

Why are you thinking of using the NOS purge kit? Does it have an electric selonid vavle? If so then it should work great. Most people just use a ball valve connected to the bottle to regulate flow. Im not familiar with the NOS purge kit but if you can connect the CO2 bottle to the spray rail and have a way to turn the flow on/off then it will work.

I've built one, will be running it at the track by mid March.

Total invested.....<$60 including having my 25lb home tank filled.

just be sure you intake is in front of the bar

^lol that could be a nightmare... yeah the kit will work the most you gotta do is get a new connector for the C02 tank to hook up

Yep, I built one a while ago. Worked great. Original cost was right around $75. Right now I'm in the process of upgrading the system a bit... stay tuned for more info.

Thank guys, for those of you that have built one would you post a parts list so I will have something to go by?

Speaking for Faster7. All he used was some compression fittings, and some copper tubing that he drilled for jets.

btw im guessing a c02 spray bar is for the IC

I really don't have the time right now to write up a full parts list and instructions. A majority of the parts were custom made by me. The old system has been ripped out, so I can upgrade to a newer system for a slightly larger IC. As such, I don't remember all the specific parts that I used. Once I get the new system online (should be by spring time), then I'll post a better description of how I did it.

Until then, here's a brief overview of what I remember:
I used a 1lb CO2 bottle (I bought a couple of them, available at any paint-ball store), Plus, a needle valve to go on top of the bottle (allows you to turn on/off the flow). I bought some SS braided high-pressure lines to run from the bottle to the IC, and I built an adapter to connect to the needle valve. I also had an electric solenoid in the line, connected to a pushbutton in-cockpit. The solenoid was the tricky part, as most don't hold up to the extreme temps and pressures. All the nitrous distirbutors have usable solenoids, but they are quite expensive. I was able to snag a cheaper one out of my shop that seemed to work ok (I'll be upgrading this on my new unit). Lastly, I built a rail out of SS tubing (1ft long, approx 1/2in dia). I drilled pin holes on the side facing the IC, capped one end, and installed a fitting on the other to attach to the line.

That is the basic nitty-gritty. Like I said, I'll post a better description when my new system is on line

Will just any solenoid from NOS work or which exact one do I need? This is the most confussing part for me , everthing else I can do.

Thanks

saxyman990

I don't know. As I said before, I didn't use a specialize nitrous solenoid, I used one that designed for a less extreme application (it has worked so far, but I have only been using very short and small bursts of CO2. There is a possibility that this solenoid could malfunction. This is part of the reason I'm upgrading the system). The only reason I mentioned nitrous solenoids is that they will definately be able to handle the extreme temps without problem.

As far as I know, any of the nitrous solenoids should work (be careful, as companies like NX, and NOS also sell fuel solenoids. These probably won't work). They have different size solenoids available for use with different size shots of no2. You may want to size the solenoid according to how big of a sprayer you're going to build. Just a heads up, though: nitrous solenoids are usually $$$$. Try looking on ebay or something like that to try to find a used one. These are just suggestions though.

Like I said, I don't have experience with any nitrous solenoid. That was just a suggestion of one place to start looking.

Thanks, I guess Im going to call NX or NOS and see if they will suggest a solenoid. When I find out I will post so those who come behind me can benafit aswell.

Faster7 is using a purge solinoid.

93rotorhead

Ok, thats kinda what I had in mind but now that I know it will work I think I will use it.

faster7

Price was right.



Have a lead on some ~$30 solonoids designed for CO2. Fingers crossed.

fastcarfreak

what happens if CO2 gets in your intake?

Liquid Anarchy

You have a boost leak from your intercooler core?

faster7

Nothing detrimental. If it's more than a wisp the mixture would be richer than usual, as CO2 is not combustable.

Car will bog hard if you are moving and have a hot air intake. Best to use between runs or staging.

Great entertainment value for scaring the carp out of pedestrians crossing in front of you.

Purge valve works. Use a jet to limit flow. You don't need full bottle pressure to make FMIC into a FMICY!

They don't work, read this article...

faster7

They work....Just ensure the intake can't pick any of it up.

Spraying the heat soaked top-mount TII intercooler before making a pass will make a difference. Spraying again down the track, I don't see any way that the engine could ingest CO2. It's being ducted with the rest of the air coming through the hood scoop through the IC and then behind the motor at the firewall.

saxyman990

Cause if you read it on the internet, it must be true Saying "they don't work" is a very naive and immature statement.

I have seen a VERY noticible difference at the track. Of course, I don't spray while I'm moving. Generally, I spray before I make a run. This cools down the heat-soaked IC, and has the same effect as icing down your manifold. Works GREAT, and I have personally seen it take a few tenths off my ET.

i have been at a dyno and watched a factory turbo charged volkswagon pick up alomst 30 hp at the wheels with a intercooler sprayer.

but yeah your right they dont work. lol

faster7

I agree.

Heck, I believe that article 100%. I just get more out of it than a simple "They don't work."

Like this:

"When sprayed onto the intercooler, both gases netted a 9 hp gain to the wheels."
