Flamer
Turbo Mini Forums

I have a twin pipe exhaust and will be looking to fit a flamer kit to it in the coming months. I am sourcing a Citroen 2CV coil as this has 2 terminals and can therefore run 2 plugs (one for each pipe) rather than a standard coil with just the one terminal which then requires some form of alternating current from one plug to the other.

My question is this - I've seen an "ignition coil driver for flamer kits" on ebay and don't quite understand what this is. I was thinking that if I piggyback from the original coil's power feed to run the 2CV coil, and insert a switched relay to control the power feed to the 2CV coil then all I'd need would be the leads, plugs and the whole lot mounting at the back end of the Mini. Am I missing something here???

Jim

nooooooooo please dont fit one!

"Am I missing something here??? "





Yes.
You are.

Oi oi! Less of the nastiness

The reason I'm asking is because I'm thinking about fitting it as part of a conversion for show purposes only. I only need some techincal help - besides which I think it'll go really well with my fluffy dice, backwards-baseball cap and burberry pants (NOT).

So c'mon - someone must be able to help me out here? (other than by putting a 9mm in the back of my skull, thank-you-very-much before someone else suggests it).

WEll I can speculat... but as its a pointless mod I wont :p

Its far to "kev" for me I must be getting old!

why not get mapped ignition with your money instead, then you can have it happening for real, I know mine does, when changing down when hot, pops, bangs and flames out the back.

How much does it cost for mapped ignition?

your looking at around ?800 for ecu with sensors, then you need to make a loom, and get it mapped

Knackers to that!! ?800 is waaay too much for my poor humble wallet!

So c'mon - someone must be able to advise on the original question of setting up and running the coil???

http://www.kustoms.com/bbc/garage/flame/ <----- there is quite a bit of into there mate, even some diagrams further down the page, hopefully it might help

ok Jim, Each to their own i guess! It was just my sense of humour, you'll understand when you meet me!!!

As regards simply putting a 'spark plug' in the exhaust... i've never understood how this makes flames.
Anything coming out of an exhaust manifold (ie, even before the tailpipe) should not be flamible if the engine is well set up!

You need to get excessive fuel coming out of the engine, in order to have something to ignite.
A few ideas - either put an injector into the inlet manifold, such that it opens at the same time as you are triggering your 'flamer' coil; or try messing about with the choke, such that you pull the coke out at the same time and have it flood the engine with petrol. Any variation on either theme will do what you want - maybe a few other tricks aswell?

From what I've read you fit a switch intercepting the power going to the engine's coil which, when flipped, switches the power to the coil powering the spark plug in the exhaust. The engine gets no spark but inertia causes the rotating mass of the engine to carry on turning, meaning plenty of unburnt fuel is put through the exhaust and onto the sparking exhaust plug

You then release the switch before the engine stops completely and that's about it. Engine coil restarts and everything is running as usual again.

ewww Flamer kits :(

Fit an anti-lag kit or something instead


I know a guy who's ripped holes in exhausts trying to get his to flame, so its probably not the best idea..

thats uncanny!!.... i fitted one last night... was realy bored so knocked one up as a bit of a laugh!... dead simple really

the control boxes basically pulse high frequency from a NE555 timer IC. the is is then fed into a fast switching NPN power transistor. this feed is then fed into the coil input and voila!

dont buy em off ebay, unless really cheap. as you can make them for about ?5 or less. (mine come to ?11 for 2 kits as i have fancy boxes and heatsinks.)

got circuit diagram from here

you get some nice flames on overrun...

BIG problem is the plugs... as they have a M14 x 1.25 thread, and its EXTREMELY difficult to find these nuts (you need to weld them to your pipe.)

I ground the thread off and re tapped with a 1/2 UNF thread.

other prob is designing the circuit small enough,,, but i now have one to copy.!!

dont bother with relays, they wont last 2 minutes.

dont bother switching power to coil of either, not a very clever idea...

need more info etc, let me know.

and yes, i have to agree, they are a Very Kev!
