There's another way to do it without messing with the fuel lines.
*****DISCLAIMER*****
The mod listed below is to be done at your own risk! I blew up a muffler cuz I left it on too long!
*****DISCLAIMER*****
Parts needed:
1 Spark Plug
1 Old style ignition Coil
1 Toggle switch
6 Foot Spark plug Cable
1"X1" chunk of 1/8in steel plate
What you do is:
1...Notch the end of your tailpipe 1"X1"
2...Drill and thread a hole in the Steel plate to screw in the spark plug. Weld this into the 1X1 Notch.
3...Mount the Coil in the rear cargo compartment and run the MINUS lead to ground.
4...Run a lead from the POSITIVE terminal on the coil to a toggle switch. Run another lead from the toggle switch (fused, of course) to your battery.
5...Run the spark plug cable from the coil to the spark plug in the tailpipe.
At a normal idle this doesn't work too well, but when your rapidly accelerating you flip the toggle switch to energize the coil, which fires the spark plug, which ignites any unburned gas in the exhaust!!!!
Roar's like a lion,too!!!! Just make sure you only use it for a short duration (see disclaimer above!) as the flames will eventually travel up the tail pipe and cause some major damage if left on too long!!!!!
Yes, the plug needs to be changed very frequently due to the carbon buildup, but if you change plugs and keep the old ones for this purpose you'll have an ample supply!!!!
Anybody else ever done this?
