it would be just a couple of wires to run and a propane line right?

 

yeah what exactly would be involved in this set up

 

You will need two relays that work on the same switch to ensure that the propane valve and coil light at the same time. Just use a standard coil you can pick up from any autoparts store, a regulator with solenoid, propane line tapped into the the stack with a bung, spark plug with bung, and of course the propane tank. Regulate the propane to 30psi and you're good to go.

 

how big of a tank would be best? a little torch or a fryer bottle like 30 lbs or what

 

Oh no...you're going to need a 5 gallon tank just to blow some flames for a couple of minutes. At 30spi you'll drain that tank pretty quick.

 

i c $$$ money being spent in propane

my truck is a gasser and has single in out muff, and a Y pipe behind it. inject the propane behind it and run the spark plugs behind them before the tips or what? could i get a muffler shop to run the bungs in so i don't screw any thing up, what kind of nozzle should i use to inject the propane? oh and what kind of relays?

 

Yep, its going to take lots of propane. You will want to run the lines and plugs as close to the tips as possible for safety. If the engine stalls or dies you dont want gas being trapped close to the muffler and then ignited. I would be a good idea to tie the relays (Bosch 12V/40amp) and switch to an ignition source in the fuse block in case the truck dies so it will cut off the ignition source and propane. Any muffler shop will be able to install the bungs in a matter of minutes. No need for a nozzle, just run a standard propane line and screw it into the bung. You'll want as much saturation with the spent exhaust as possible because the airborne carbon will try to snuff out the propane. Keep in mind that this system is only going to allow you to flow flames while you're sitting at idle. Any throttle acceleration is going to snuff out the flame.
