Has anyone ever used a nitrous kit and simply filled it with propane instead? The propane injection kits seem pretty ghetto and I dont want that big *** tank in my cabin. As long as the propane wont harm the solenoids I see no reason why it wont work.

 

I have never heard of using propane on a gas engine. But, I have seen it been done to a Dodge Ram turbo diesel engine on tv. They installed a NOS with propane injection. It worked awesome for instant power. Don't really know how it will go with the gas engine.

 

People do it all the time, I just need to know if it will work with a nitrous kit.

 

You can't fill a nitrous bottle with propane, gas stations just won't do it. The nitrous bottles are built with a siphon to get the liquid nitrous out of there, propane bottles are built for gasses. The threads and fittings on nitrous bottles are apparently different, too.

 

Actually this is something I have been researching for some time. I believe you may have oxidizers and fuels confused, but willingly or not, you have touched base on my pet project. Nitrous Oxide is an Oxidizer whereaz Propane is a Fuel. Replacing Nitrous with propane will not do you any good, but injecting the two together can produce most impressive results. Propane averages (depending on the source and testing facility) around 104 octane (MR/2 method). Imagine a fuel that is 104 octane in a "wet" system that has NONE of the problems associated with a liquid fuel such as fuel fallout (aka puddling). Ideal atomization, increased octane, and (in theory) 50 state CARB legal. It's closer than you think.....

 

yeah, impossible to fill the nitro bottle because its a liquid, so just get a propane tank and hook it up, the purge system will be funky cuz its just air, and it will SMELL like ***

 

im putting together a propane/nitrous kit.110 octane from the propane should add that safety margine im needing.

ill be using a propane tank,smallest i can find.then running hose from front to rear,to a air compressor regualtor,then through a nitrous fuel solinoid and then to the intake right along side of the nitrous line.

propane pressures are only about 130 psi,so you can use fuel injection hose and clamps,and you dont need to jet it if you just get a regulator and adjust it accordingly.you should use a nitrous fuel solinoid vs a nitrous gas solinoid because the huge difference in pressures and a fuel solinoid can handle up to 250 psi.

both propane and nitrous are stored in liquid form

 

one thing that isnt mentioned is the energy content of propane in relation to gas. propane has only about 74% the energy content of gas, so 25% more propane will need to be burned in order to get the same power of gas and probably more nitrous as well.

if air/fuel ratios w/ propane/nitrous are near the same as gas/nitrous, a 12lb nitrous tank would be needed to get the same # of runs as a 10lb bottle. NX makes one.

 

So you think I can place propane in a nitrous tank?

Im getting conflicting answers, does anyone know for sure?

 

propane is stored at a lower pressure than nitrous so the tank itself would be ok, its the valve that i'd be more concerned w/ since propane is flammable the valve on a propane tank probably has something to prevent any kind of flame from entering the tank.

are you trying to just spray propane into the engine hoping for somekind of performance gain? cause you're not gonna see any unless you getting more air into the engine too.

 

Try not to get into any serious fender-benders with a propane tank on board.

Why do you want to do this? Propane tanks are cheaper than nitrous tanks. Propane is stored at less than 200psi. Nitrous is stored at 800+ psi. Air/fuel ratios need to be 12 parts air to 1 part fuel. Your propane tank doesn't need to be that large. The smallest one you can find is going to out last even a very large nitrous tank. Propane pressure varies, even more than nitrous pressure, with temperature changes. You will need to devise some method to regulate the pressure. You cannot regulate the pressure of liquid propane.

 

So if we know propane has a higher octane rating than gasoline at the pump and is supposedly cheaper than gasoline why hasn't anyone converted their turbo gasoline car to a propane fueled vehicle?

You could have high octane and a cost less than low octane gasoline!

 

It can be done! I run it on my TALON and let me tell you it is badass. Here is how you do it in a nut shell. The easiest way to do this is run a wet nitrous setup and replace the fuel side of the nitrous kit with a propane injection kit. I run a propane injection kit from http://www.importpoweronline.com they are cheap and work great. You set the propane to inject with the nitrous. So you are injection 108 octane fuel with a nice big shot of nitrous and the car loves it. If you want a more detailed description of how its done check out my site in my sig

Actually there are a **** load of REGs on the market for liquid propane! And you are correct a 5lb propane tank last me about 3 months in my car

its 104 octane

cause mileage would suck, and it costs alot to convert the whole car to propane.

 

Ya its not worth it really to convert the car over, but very worth it to inject when you need it!

Actually the regulators are for vaporized propane, not liquid. You cannot regulate the pressure of a liquid like nitrous or propane. Thats the whole reason people use heaters on their nitrous bottles. The pressure is directly proportional to the temperature of the bottle. Other than changing the temperature, there is nothing you can do. Otherwise people would have nitrous regulators, but they dont.

I have a (vapor) propane regulator. Its a dual stage heavy duty regulator used for brazing with propane. One thing that hasn't been mentioned yet in this thread is a component called a vaporizor. If you hook up liquid propane strait through to a regulator you can freeze and damage the regulator. In an environment like a car where the liquid propane is sloshing around this can be a problem. You want to tap the bottle from the top so you only get teh vapor, but if some liquid gets in there, you may have problems.

From everything I've read, all of the conversion kits to switch a car away from using gasoline use a vaporizor. In countries where gasoline is $8 a gallon this is popular. Having a vaporizor may not be a necessity, maybe its just a safety thing. Still, I would hate for my regulator diaphram to freeze and burst, leaking propane into the cabin of my car. Not good.

I've never tried, but using a simple air compressor regulator for propane may not be a good idea? If you try be careful.
