V8 Supercars

The fire coming out of the exhaust of V8 Supercars looks really really cool and i was just woundering if anyone could tell me how the flame comes out and if so how can i make my car do that

thanx

Cant anybody tell me.

Come on this is a Ford forum and knowone knows about the V8 supercars.

The motors are 650hp, it is excess fuel. Run your car stupidly rich, and you *might* get flames.

The flames out of the pipe are the result of the "overlap" that the camshaft has.

That means that the intake vale and exhaust valve overlap, meaning that they are open at the same time for a short period.

As the exhaust valve is closing the intake is opening meaning that fuel is being sucked straight through the combustion chamber and out the exhaust, where it ignites when it gets oxygen as it exits the pipe.

They use the "suction" of the exhaust gasses to "suck in" the intake charge (air/fuel mixture), this in effect gives a small "ram effect" allowing more air/fuel to be "rammed" into the combustion chamber. More air/fuel for ignition = more power.

man do it the backyard way. get an Ing. coil and run one wire to the Batt. then the other end to a spark plug and drill a hole in the exhaust and weld it in there. the get a small bottle of propane like the camping size and run a line dwn before the plug. rig up some switches for everything, turn on the pwr, and turn on the gas. it sounds really really stupid i know, but it sure as hell looks good

Ummm... I'm not sure whether the flame coming out of your tailpipe on overrun is either desirable or legal with a street exhaust. Although the V8 Supercars run a nominal 98 dB limit and use a silencer, the resemblance to your street exhaust with a catalytic converter and usually a couple of mufflers is at best casual.

Remember these are race cars not hotted up street cars please. We can dial up huge flames on overrun in the turbo race car by sitting down with the laptop and programming a whole pile of retardation on throttle lift (which effectively gives some anti-lag properties) so a whole pile of unburnt fuel goes down the exhaust manifold. Great for flames, gives good throttle response as the turbo continues to spool and turns our exhaust manifolds glowing red which means we have to replace everything (manifolds, pipe after turbo) more regularly - hurrah more labour and more cost... and you could be the genius who was demonstrating the anti-lag to his mates and managed to burn the carpet in his interior after the exhaust got so hot...

As for connecting a propane line into your exhaust line - that's Darwin Award material.

Darwin award material. Lmao that just cracked me up so hard that i fell flat out of my chair =D
