Anyone running a CO2 i/c sprayer?

[turbowrenchhead]

I was looking into one of these. Looks like it can make your i/c more effecient and more consitant at the track. I am thinking of making my own kit. I just am wondering what kind of on/off solenoid I need to turn it on? Do I have to go with a NOS solenoid? What pressures are these putting out? I think with a on/off switch and a hobbs switch and an optional bypass so you can spitz it when sitting still would work real good. I think the hardest thing would be to make is the actual tubbing that would mount in front of the i/c. That might take some time drilling a bunch of holes in it. But I gots lots of time. What do you guys think about this?

Well I did some running around today. I think I can make this work. The only thing I'm still waiting on is the on/off solenoid. There is one place doing checks for me. I hope it doesnt cost alot.
I know where to get a hobbs switch cost is $22 and it has a knob. I alos am going to use an ashtray plate to mount the switches. I found a 20 pd aluminum tank for 105 dollars with the first refill free. Then they are $17 after that. They opperate at 800 psi. I can get the braided line from there too and a regulator if needed but I dont think I need it. I can also get a psi gauge to keep a check on the tank pressure. I found some 3/8 straight copper tubbing and I bought some 90 degree fittings. That cost me appox $20 with the silver solder. I have to draw up a plan for a sprayer and custom fit it to my i/c. I think it will work nice and better fit my i/c and have a much larger tank for less then what the kits are selling for.

Good idea using the copper with 90's..pretty easy to use with a propane torch..your done.

How are you going to adapt the braided line to the copper pipe??

AN to compression fittings are available.

Saw some today at NAPA.

Should hold a few thousand psi. but you should double check the rated specifications.

Isnt it cold enough in Wisconsin that you dont even need an intercooler?

Wonder how much pressure would be on those copper sweated joints? I know it would be drilled full of holes so it would probably be OK.

I have a copper piece that has 3/8's pipe thread on it. I have to sweat it to a tee. I am still trying to find a cheaper solenoid. If I can't find one I will have to wait to buy the NOS solenoid. I have to finish my car first before I can spend any money on this project.

Cold enough in Wisconsin? Last week it was 95 here with high humidity. I love when its 20 degrees out and no snow on the ground yet. The car runs really good. The coolder the better.

I also thought of the pressure on the joints. I got some high tensile solder with silver in it. I think they will be ok becuase there will be a dramatic pressure drop. I have been debating to run a smaller 1/4 line from the trunk to the i/c. I think 3/8 would lose some volocity. I am just guessing. I really don't know witch on would work best. The NOS outlet is 1/8 and inlet is 1/4 so whats the point of running larger hose.
