Propain injected stacks (flame thrower stacks) need info

[GreasyFingers]

wouldn't it ignite better closer to the top of the stacks and not so far down..... seams like it would be snuffing it out down there....

I'm with you on this. Down low there is fuel and spark but little to no O2. I've seen this on a few hot rods and the spark plug is within a couple inches from the tip and the LP is put in different locations for different affects. Closer with a nozzle makes it more torch like, further is more fire ball like.

I was rolling about 80 mph up a 6% grade and saw a SD in front of me putting out a 4 foot flame out the tailpipe. Turned out to be a messed up injector, but it looked wicked. Not stacks, just a 4" turbo back.

Must subscribe!!! Lol I wanna do this if I decide to put stacks on my truck! But might do it for sure on my 77 150 lol

Seems like it needs air. Like on a propane or butane torch there is an air hole behind the flame a ways, so it might all need to be moved up

I have seen a few kit that were installed really low like mine and they worked great

Nice big flames spewing out the top of the stacks.. maybe gas injection will work better :demon:

One thing to keep inmind is with the pressure and air flow of the exhaust. You will have to keep the igniter as close to the gas as you can... I wonder how well a glow plug would work????

A few installs I've seen used them.. im not sure how to do it

All you would need is a ground and a hot wire to feed the Glow plug..

Well all you need is a hot wire coming from a switch.. It would ground out through the Exhaust system so you would need just one wire..

I don't know if that would ignite the propane though. Some one needs to try it...

 

[Powerstroke Cowboy]

How about ether injection!!!!! that would work or you could use it to light the propane easier

Glow plug in theory should work. It would be just like a hot surface ignitor on a furnace. Personally I like the idea of adding fuel at bottom of stack and ignition at the top but that would require a spark ignition. and what about one of those multi spark ignitors off of a grill with a simple extension of the wiring.

Its a good thing I just don't give a s*it let's blow something up!!

 

[Mike For Mayor]

Glow plugs are like 15$ each.... damn... oh fyi im using marine spark plugs

I like your style

I think I still have a set I pulled out when I got my truck. They're packed away somewhere in a box. If I knew where they were I'd send a couple your way.

The spark plug should work if you have a good driver circuit. I doubt a relay is going to work.
Basically you use a 555 timer to drive a transistor, simulating points. Then the coil is running just like on a car.

My buddy is a mechanical engineer im gonna see if he will rig me something up

 

[schroederness]

I dont think a turn signal relay is going to fire fast enough as those are based on resistance. Turn signals blink faster when one bulb is out because their is that much less resistance. So in theory if the resistance was greater then it would actually go slower. Now assuming that a spark plug is greater in resistance than a light bulb I am going to assume that you are sparking slower.

That being said this shouldnt be to hard to do.. Move the fuel closer to the spark and have a faster/stronger relay.

this is awsome. i have been wanting to do this with duals.

Why is it so damn cold! ! Unfortunately since its getting colder im finding it more difficult to get this done..
