With a turbo engine you have a fuel pipe which runs back to the petrol tank right?

would it be possible to take the return pipe and attach it to the exhaust manifold? Without burning the car down? lol

[Wil_h]

What are you on about? I'm guessing you're planning suiside. Pipe from the exhaust into the car is easier.

[kada1980]

and you think that would be safe and legal

[MaryQuant88]

Just a thought lol
It pays to be creative sometimes

[kada1980]

what just like this guy

No, No, No. lol Rage Against The Machine used that pic for their album cover lol


Im just thinking back to the 80's when you would see a Quattro with huge flames comeing from the back, and it looks impresive, How would this be achived in a mini, I thought somehow of making the Return Fuel pipe flow into the Hot exhaust and flames would be achived

Havent tried it, thats why i asked u guys 1st:D

i think what you are meant to do is put a spark plug near the back of the exhaust attached to a seperate coil.

then you have a switch inside the car which switches off the normal coil and the other one on.

unburnt fuel then travels down the exhaust and is set alight by the "flamer" spark plug.

This is called a flamer kit.

thats roughly the way it works i think.

someone correct me if i'm wrong but that was a combination of things one of them was the duration of the cam where the inlets and exhaust where open for longer and quite a lot of fuel was wasted into the exhaust.

if you fit a dump valve on a fuel injected engine, it messes with the airflow meter and you get overfuelling and hence flames. there are flamer kits around, which is based on a kind of sparkplug in the exhaust, as theres some unburned fuel in there anyway.

In highly tuned cars you do sometimes see unspent fuel exploding in the exhaust, normally you just hear a backfire when this happens, but the higher the performance, the more unspent fuel can get through I guess. When you see flames coming out the back of a rally car, it is not done on purpose, it is just incidental with the state of tune of the engine (and probably the lack of loads of silencers to trap unspent fuel and high exhaust gas temperatures).

I don't see why people attempt to recreate this on a road car, flamer kits are IMHO a stupid idea! NO NEED!

And as for attaching a fuel return pipe to a source of ignition???? NOOOOOOOOOO!

I know about this its the ALS right?and that why it keeps banging & popping.

Ive heared about this, but i dont want just a flame, id like when id change down it would be popping and backfiring, Havent had a mini turbo before would anyone know if this happens anyway

[Ollie180]

just thought id add that when you rev my car up and then you eas off the exhaust pops and some minis down track do the same when slowing down for bend a flame comes out

[Bungle]

batman also goes for the flamer look

[kada1980]

before i had the westy tuned there used to be some big flames coming from the exhaust, it looked and sounded good but seeing as the exhaust was only 3 inches from my elbow it wasn't a good idea!

got the carbs and timing setup and its gone away now.

My old nissan 200sx used to pop, backfire and flame all the time.

It was due to the fact i removed the dumpvalve and instead of the compressed air being released through the dumpvalve it had no other choice than to exit at the air filter.In doing this the AFM (air flow meter) senses the air passing through it but doesnt know the difference with it coming in or out so thinks it is sucking in a load of air and hence dumps in a load of fuel in which is just flushed out the exhaust and if the exhaust is hot enough combusts and causes load pops and flames.

I think that is one of the reasons Fuel injected cars anyway have dump valvs fitted as standard as with out it u run a chance of running too rich and failing MOT's and emissions........ or so i was led to believe.
