Turbo Injection

[Urban Ninja]

I have been toying with the idea of how to get an air and butane mixture through on pie for a mini easily. I was playing with a turbo jet lighter and thought that the reason that it is so hot is that it takes in air before igniting and mixing it with o2. I was thing maybe you could use this for rambos auto but for a mini? After all it must make a good fuel and air ratio. Its just an idea but the picture shows the air inlets. Think itll work? I want to make my thompson gun fully auto without having an air tak on my back or somethink.

Good idea.I didn't try it, but i suppouse it will work.You need a big flow of fuel from a smal hole.
So you will put this on the back of your tompson.Just remainding that it can turn in to a torch.

Yeah or worse a jet engine! Also my thompson has a small chamber and if I adjust the amount of fuel going out of the disposable lighter I can adjust rate of fire. Lets just hope it provides enough o2.

I think you will have a hard time, whenever I have my butane lighters hooked up to my mini's, and I try to leave the gas flow on, it usually just stays lit, and doesnt provide any force except for the one shot.

just a little tiny bit of butane and a lot of air puts out much more power the a heavy butane mix, found that out by accident -- i took a butane refill bottel and put 2 tiny squirts into a water valve cover, (man hole cover) it had about 2 1/2 cubic feet of space, and lit it up through the little hole, omg it let out a awsum ball of fire, im glad it had a little hole to excape from, it singed all the hair off my friends left side, so power full for 2 tiny squirts A-freak-en-mazeing

same concept as a propane torch there is a venuri that sucks air in from the holes, but you would still need a way to vent the spent fuels.
I don't think that the butane will be forced through a large hole fast enough to suck enough air in.
You can fill your mini off a propane torch just have the little holes exposed to the air.

If you put the ignition close to the nossle of the torch, it shoud ignite easer.

[Urban Ninja]

Yeah and maybe have one of those keyboard mini vacuum cleaners set on low power to suck up th spent fuel?

The gas needs to be moving pretty fast to suck air in. I've made big propane torches with a burner tube of 3/4" pipe, and to get it to actually suck air from the back requires the air to be moving pretty well. Look up venturi. I think that a mini vac would work but you would need to have it on a timer or a button so it wouldn't suck out the new fuel and air.
I don't know what i'm talking about with electronics but here's an idea.
You have a turbo gas injection thingy (torch may be a bit slow on filling but its worth a try) with premixed air in it on a small solenoid valve. Then you make a circuit that opens the valve, fills the chamber with fuel, closes the valve, fires the ignition, then it turns on the vacuum and then shuts it off again. That could be hard i don't know electronics just an idea.
