Does anyone know if the same principal works on the Chimaera (have the sports exhaust allready) as I would love to melt the front of all those idiots who sit on my tail in their euro box's ( how anyone thinks a a 1.6 rep mobile is going to keep up with a even a lowely 4.0l chim is beyond me) on the M25 in the mornings how satisfying it would be to watch the panic on thier faces !!!!!!! He He !!
the car i had before was an e/cozy
tuned to 400bhp,and to spit flames,i fitted a spark plug 12"from the end of the exhaust and had it sparking via a button on the gear stick wich i pressed in between gear changes..and 4foot flames were there in my mirror...god i miss that
there is a web site on this some were,and how to do it

Was recently in Aus. and what the hot rod boys there do is to cut a thread into the tail pipe near the end, insert a spark plug fired by a 2nd coil and feed from the LT side of the ingnition (so you have a pulse for the plugs) then attatch a fuel line and nozzel to the exaust just behind the plug,fed from an electric pump and dash mounted switch and hey presto you have the ability to belch fire at will!!!.sounds extreme i know but looks awsome at night!!
Or just lean off the mixture and retard the ignition alot.Won't be much fun to drive though........
p.s be carefull they are made of plastic......

That sounds *fantastic*, especially with the upswept exhaust of my s3!
Given my cavalier attitude to safety and over enthusiasm for building splendidly childish things like this, what are the chances of...
1) Blowing myself to kingdom come [1]?
2) Melting the back of my car [1]?
3) Being locked up?
4) Simply dying from excessive giggling?
[1] When you turn the fuel flow off does the pressure of the exhaust gases effectively extinguish the flames rather than let it lick up the back of the car or suck back into the exhaust?
Pressumably this would only work without the additional fuel flow to my exhaust on my s3 if there was unburnt fuel exiting from the exhaust. How do I find this out (without hanging off the back of the car with a disposable lighter while someone accelerates through the gears)?

CAUTION......MATE
just try the plug with out any fuel......MEGA DANGEROUS ......my cozy flame'd well with just the plug ,using another coil and powering it up via the engine ,by a switch mounted onn the gear stick wich i press in every gear change ,as the button goes in the power supply is reduced to the engine,becouse the other coil is being fed,this richens the engine up while the switch is in ,,resulting in flames...the switch must be released after the gear change becouse the engine will suffer mega power loss,and resulting in engine damage...sorry i can't spelll.

a mate of mine told me that he'd achieved the same effect on a Bedford van by drilling a very small hole in the exhaust manifold. When you back off the throttle it'll pull air in through this hole and allow any unburnt fuel to ignite in the exhaust system, resulting in 2" long flames from the tail pipe....well that's his story anyway.
MikeE - the land rover has a dodgy manifold gasket anyway so this does happen on the over run. However, the exhaust is so long that all you get it a lot of back firing and, as far as I know, no flames.
Theneed4speed - Don't worry, I wasn't going to route fuel to the exhaust as that does sound a bit insane. When you rigged up your spark plug to the second coil, did you have a constant feed to the coil when you pressed the button? I was thinking of having somehow an pulsed feed to it (like a normal spark plug feed) so the effect on the engine wasn't so pronounced. I was planning to do this pulsing on the low tension side but don't know if the coil will be able to handle it or wether I'll just get half the output from the coil. I'll have a play and see what happens. Thinking about it I could rig up some sort of recycled points from a single cylinder motorbike on one of the pulley wheels and then it would pulse once per revolution on the high tension side which should work better.
Don't tail-gate any green ex-military land rovers with over sized wheels in the Newbury area :-)
