I have access to some solenoids, theyre used for the ether injection on industrial equip. I'm thinking they run the same threads as say a benzomatic or Coleman propane bottle. Any idea how much pressure is crammed in a little Coleman? It has to be 45 psi at the least to over come boost. Would I need an actual nozzle if I mount the cans upright (I know liquid propane in a cylinder is a no no) I wanted to run two bottles/solenoids. Each solenoid has 1/8" npt port. I was thinking of running plastic air line. any cons? I could get a braided nitrous line if needed. Unfortunately they're 24volt solenoids which wouldn't be too hard to resolve.

The pressure on those bottles is 150psi. Yes, they would overcome the boost pressure, the problem is that they would only last about 20 minutes if your system is always using it.

What are you trying to do with the propane?

More power or fuel mileage?

 

Didn't expect them to last too long unregulated, not that they'd need regulated bc of the orfice in the solenoid. Just wanted it for a bump in power if I go to the occasional sled pull

propane injection goes in the intake tube before the turbo to help atomize the propane. I believe you only use about .5 to 1.5 lbs to push it in and it usually runs off of a boost reference regulator. I have a power shot 2000 but haven't installed it yet. (been thinkin the same thing) there is a lot of mixed views on this subject

 

I wasn't sure if you ran it pre turbo or not; but at any rate propane in a gaseous form won't need to be atomized, hence installing everything up right. Dunno if I'd feel comfortable shooting flammable liquid at my turbo anyways .

The biggest problem if read about is getting a gulp of liquid in your system that's why i chickened out and went with the kit stuff, instead of a home made one. hopefully some of the guys that have ran these kits will chime in. these out fits brag about 75-100 hp gain but i haven't seen it yet. that much gain for 200.00 bucks sounds cheap.

 

I though about propane myself, but too much to go wrong and your carrying around a flammable gas everywhere you go in a pressurized container... There is a reason alot of guys quite running it and you don't hear much about it anymore.

That's why I chose to go with Nitrous, you can build a kit cheap, its easy to tune, and much safer. I loved spraying my truck, INSTANT spool up! You can even get a progressive controller for it to tune how much you get at different boost levels.

 

Nitrous is turbo in a bottle though, propane is a fuel system in a bottle.

It works, I don't think there's any reason to put it in after the turbo. There's no reason to use an "orifice", you're not worried about atomization since it's going to come out as a gas. My "propane kit" I did a science project in high school with was a barbeque bottle blowing into the air box through a rotometer. Noticeable power increase at around 2-5 LPM of flow, above 10 LPM and it just started to blow eye-watering raw hydrocarbons out the exhaust.

It doesn't matter what you use to control flow rate of the propane, you just want to use SOMETHING so that you know how much you were flowing yesterday is the same as what you are flowing today.

 

BEGLE1, did you drive this science project around to get some mileage numbers or just noticeable power, I have a (kit) just kinda discouraged from the things i have read. I would like to try it though. I get about 15-18 mpg (depending on how i drive it that day)I also realize my rig is jacked all out of proportion.AND (propane isn't cheap) I'm thinking for extra power with the better fuel mileage as a bonus.and no you are not responsible for your thoughts, I would like to hear them though, haha

 

The science project was all doing the same run on a smog check dyno, each run at a different propane flow rate, while measuring emissions.

And I managed to lose all the data at some point through the years, unfortunately.
