My question is how does the acetylene gas regulator work with the propane bottle when the threads on a propane valve are left handed female threads and the acetylene valve is male with right hand threads? (Yes I did just take the regulator off my acetylene bottle and look at it to be sure, plus the bottle is in the back of my truck.)

propane burns at 3254 degrees F flame temperature and acetalene burns with oxygen at 6000 degrees flame temperature F.

There's an adapter you can buy at a welding supply store to hook your regulator up to propane, I used it for a while when I was scrappin alot of steel. Still prefer to cut with acetylene. :c:

.

What about propane with oxygen? If I'm not asking for too much.

3992 F degrees propane w/ oxygen just about 2/3 temp of acetalene /oxy

Back to the subject, I found another valve. This valve has a solid yellow brass lower body and stainless steel inners. The other guy couldn't tell me what was inside his valve but he new it wasn't stainless. This is a better valve for less money, 26.90+4.95 shipping 1/4" or 3/8" from " valves4projects " on EBAY. Valve does fuels and gases and hydraulic oils, 12v DC.

I'm interested!! I definately need to put together a system on mine.

"Propane article"

for the idi guys. feller had no mpg increse.

OK, I got mine done !! The valve I told you all about last only took 3 days to be in my hands, and I ordered it on Monday the holiday. I took a pic of it laying on the invoice if it's readable. I only took it for a short backroad ride after finishing it but I definately felt it when I hit the switch. Yippee !! Thanks Guys !!!!! By the way, I had everything but the valve and the switch so the whole thing only cost me about $33.00. :jump::jump::jump:

hey im a long way from being done enough with my build to get this info built in ,but i enjoyed the info and the practical expanation-thanks for putting this up-i will be leaving room for a propane tank when i get to bodywork for sure:tu:

dave59.......do you have an up date on your set up ? im thinking i like it. :pca1::pca1:

:tu:Thanks. It's working great !! Thats a really sweet valve I found, works really well and with the stainless guts it'll outlast others. There's a pic of the invoice in a past post of mine showing the valve, got it off EBay. Good luck with your install !!! :tu:

dave, thinking about building this setup, I've got everything lying around except the solenoid's and the adapter to get my Regulator to the LP tank. Question, what PSI are you feeding your engine? I am thinking about running 2 solenoids, One on the tank side, and one in the engine bay. The arming switch will power both solenoids, but the Solenoid close to the engine will be activated by a 2-4 psi Hobbs switch that way there is only 2-3 feet of hose to fill when the solenoid opens, and once armed it will only kick on when i hit 2-4 PSI (have to decide where ill set it)

I'm only feeding ! 1 to 1 1/2 psi cause I want the mileage improvement, but even at that it's still a nice little power boost. Some guys talked about 5 psi for power but then complained that they ran through propane too fast (go figure !!). I don't really see the need for two valves, but if thats what you want it'll just add a little more cost to the project. It will hold some gas under your hood too even when not used if thats a concern? I think it's pretty much instant with the one valve, your pick. Good luck Ryan !!
