Help me design my CO2/NO2 intercooler sprayer!!!!

[Jtultra]

ok, So I'm thinking of building a CO2/NO2 sprayer for the intercooler from a 20 oz Paintball tank. My main focus here is to use parts not intended for a car, i.e. Home depot parts! I have included pic of a rough CAD drawing of what I'm thinking of.

I want to run a long thin metal pipe, I'm thinking maybe copper across the bottom of the intercooler, I'm thinking the front of the intercooler is best. The pipe will have a bunch of small holes dilled into it to direct the CO2 onto the intercooler. I'm planning on attaching a fitting in the middle of the pipe so I can attach a braided hose line. (ones for refridgerators, much much cheaper).

now here's the kicker, I want that braided hose line to attach to some sort of purge solenoid so I can release the CO2 on demand with a push of the buttom. I was thinking maybe nitrous purge systems, but they're atleast $100 and I'm sure I'll be using like half of the parts, so in my book, its not worth it. So I'm trying to find alternatives, but I don't know what.

Everything after that is pretty self explanatory.

I'm at a complete lost with this purge system. I'm still doing my research, but this whole plan hit me yesterday while I was at work. I was playing with dust sprayer and I flipped it over and started frezzing stuff, then it hit me ! why not cool down my intercooler with CO2!!!!????!!!

I was also thinking CO2 or even No2 wouldn't be a problem if I just went to a paintball shop and got it refilled.

I'm a little skeptical about the gains, but if I'm able to get the intercooler to maybe close to 20 degrees or whatnot for maybe like 5 seconds, it might actually make a big difference. This is just one of those projects that I just want to attempt, I could by those nitrous intercooler sprayers, but they're $$$$$ and I won't have the satisfaction of making it myself.

but I really need input on how I can purge it on demand, I think it'll be a big hassle if Ihave to manually open the valve on the tank during a race at a drag strip.


Any thoughts? comments? suggestions? ideas? improvements?

harder than you think... Home depot parts wont work, my friend has already tried it. Just get a cryo2 kit like a 5 lb bottle. I am using it for the intercooler also.

well I have access to a Mill and Lathe machine if I need to make any threads or what not. I'm not expecting to just buy pieces that magically fit together in the system I want. But there is no way, I'm spending more money than I have to.

nice demo but ughhhh :ugh: they are talking about spraying nitrous on the intercooler

[blitzceli]

makes no sense since he is asking for a intercooler spray bar...

hmm... it will prob work. But I think that copper pipe should be infront of your intercooler not at the back.

yea I agree, that was just a quick drawing.

alright, I think I'm going to buy a Cryo2 selenoid valve, I found one for 55 bucks. Its the cheapest of selonoid valves I've found. so... :shrugs:

This thing will probably work, but probably not for long - i.e. it might be fine for 15s drag-runs, but it doesn't sound like something you'd be using much on the highway.

Also, what are you going to do about mapping for when the CO2 is firing? If it works, your charge air will be significantly denser while the CO2's firing, so I guess you'd need to adjust the A/F to compensate i.e. add more fuel.

Lastly, CO2, unlike nitrous makes rather excellent fire-extinguishers, you really don't want any of that going into your air-intake ;)
