How does the flame come out of the exhaust?
Can anyone please tell me
Its un burnt fuel left in the exhaust on over run
It's either unburnt fuel in the exhaust flashing over, usually due to no catalytic converter or a flame thrower kit which is for show only http://www.hotlicksexhaust.com/ available there and other places
No catalytic converter and run rich as hell.. Or buy a flame thrower kit like he said
another thing it could be is if your car is turbocharged,what happens with that when you are at high rpm's and then gear down and decelerate that pushes backpresher and flames through the exhaust.or if you have blue flames coming out that would be because you have nos but other than that anyone of the other peoples posts also works.
thank you!...all......how much will it cost for a flame thrower kit...for a nissan skykine 2004...
Most flame thrower kits are universal, they retard your timing or kill ignition flooding a few cyclinders with fuel than expelling it into the exhaust where a spark ignites it near the tail pipe. That being said the output of said flames is lackluster at best, you get a trickle than a sort of woosh of flame rolling out all the while your engine sounds like its about to crap out. If your looking for the high intensity jet type flame (mimicking NOS or nitromethane on a highly modified engine) you see in the movies, they use a CNG (natural gas) injector and some fancy nozzle work, HIGHLY STRONGLY UNCONDITONALY NOT recomended for any vehicle that will actually be driven on the street. To answer your question about cost, expect around 125-200 US dollars for a flame kit depending on how many pipes you have at the rear.
no offence, but that's bullsh.. flames from a turbocharged car comes only when it's equiped with a blow off valve and a MAF sensor before the turbo. when you release the pedal the air that was already measured is released out of the intake system through the BOV, but fuel is already injected for that air, so mixture becomes too rich and unburned fuel ignites in the exhaust.. that is if you don't have a cat.
But only racecars are allowed to not have a cat. Street cars are required by law to have cats but hey I already know how vilius looks at laws so hey no cat + illegal = :)
in theory it's quite easy. - manage to somehow have (unburnt) fuel in exhaust - ignite it running rich and attach a spark plug in exhaust could yield a decent result. However, I don't support the idea of mimicking such dangerous thing. (for public road)
If your talking about the little blue flame you see in all the movies...thats cuz the cars are running nitrous oxide. Even though the tanks may be closed, small traces of the gas leak into the combustion chamber and cause the expression of blue flames. If you notice when spray is being used, a constant blue flame can be seen. Blue and white flames being the hottest flames and otherwise they are impossible to achieve on a stock vehicle to my knowledge.
Yeah, you know me.. but I just love the smell of hydrocarbons.. and with cat the only thing you can smell is sulfur.. ;)
stop watching movies..
Un burnt fuel particles engaging with the V. hot exhaust and a rush of O2 (oxygen)
I own 3 pre-1971 vehicles. all carbureted. unburnt fuel is just part of life. and wiring a 2nd coil to a sparkplug in the exhaust pipe, well, could be useful if rioters were crowding your car.....
