    is that the only way you could do it if you remapped your ecu to overfuel?

    highly tuned cars do it also dont they? and turbo cars?

    right when you let of the throttle the car is still injecting fuel but it does not ignite in the cylender
    so you get unburnt fuel going into the ot exhaust
    this then ignites and comes out the bak as a flame

    ususally some level of tune is present to get it to flame

    flames are from unburnt fuel, why you want to drive around with flames all the time i dont know.

    de-cat + straight through normally causes flames on a VTS if you sit and rev it.

    i laughed a few times with my vts when coming into junctions roundabouts
    car behind comes right up close so downshift and get the little pop and see the flash on there headlight
    they soon back off haha!

    also funny to do it past a group of chavs and get a nice big pop and hear them shouting about how that was phat and i must have a butane kit lmao!

    yes i know its chavvy behavior but i guarantee im not the only 1 on here that likes a laugh with it

    As people have said it can be done but to get flames you need 3 things, fuel, heat and air. The fuel will be unburnt fuel from the engine, the heat can be supplied by the exhaust system but on a saxo a spark plug is normally used and the air you get from erm, well the air. It's a normal occurance with turbo'd cars as the heat from the turbos causes the exhaust system to heat up, and when you lift you foot after hard acceleration then most fuel systems will allow a little amount of fuel through the engine, then when this fuel hits the very hot exhaust system you get flames. Lots of flames.

    what benefits is there between a 4-1 and a 4-2-1, would a 4-1 give better performance?

    anyone know what this may of been?

    If you use a standalone ECU, like the Predator from RCD Performance, when you reach the limiter it cuts the spark (standard ECU stops injecting fuel) which generally means when you change gear and put your foot down there is a whole load of unburnt fuel in the exhaust waiting on a spark

    The flame will not go back, if the engine is running exhaust gasses are leaving the engine and will stop any flames going back into the exhaust and to the engine

    you can usually tell if your getting flames when it's dark the back end will light up yellow/orange. Only time I've seen it happen, never been able to tell in daytime

    You'll find it difficult to make a TU N/A flame naturally..Even the hugely high strung and high revving S1600 engines dont flame..You may get pops etc but not a proper flame and imo, flames out of the exhaust suck big time unless its natural because your car is 1 million horsepower and is turbo'd etc..

    turbo it and build your own anti lag system! not a rev limiter or launch controll a proper anti lag lol

    Valvers tend to flame easily with a decat, the 8v dont as much I've always seemed to notice from people trying/talking about it.
