Flames out the rear
Discussion
)I know it can be done but how and is it a good idea?? 
MONKFISH
How do we do it??
Not entirely sure how the SC setup works, but I would imagine, when the throttle is shut, there is still some presure left in the intake and this may blow back over the AFM causing a slight over fueling for a few seconds, thus producing flames.
Very common cause on jap turbo vehicles
On over run on my 200sx with 400bhp, if everything was hot enough, 3 foot flames werent uncommon on track

I believe its some ignition thing in the exhaust
i think its like a spark plg thing
might be worth asking the max power boys!!
At £500,000 i dont see the Max Power Connection!!!!!!!!!!!!!yep. my skyline used to flame like a bitch (was running very rich) after i put a downpipe on it and decatted it.
every time i changed gear giving it some, she used to spit huge yellow ones (and i mean huge!!) used to light up dual carrige ways at night!!
wasnt brilliant for performance or fuel consumption but it was good fun.
it just excess fuel igniting on the hot exhaust..........you can do it with n/a cars if you remove the cats i beleive im sure they run rich enough at the top end

I bought a non running Nissan Pulasr GTIR and it has the after burner kit fitted.
Very Chavy i know.
There is a coil in the boot and a spark plug in the tail pipe.
I think it cuts the engine ignition for a fraction of a second so unburnt fuel goes through the exhaust which is then burnt at the tail pipe.
I have never tried it yet as the car is still non running but i am sure it will be one of the first things i do when i get it running.
I am told by the last owner that the flame was around 1 to 2 feet long. WOW!

The exhaust has to be hot enough and fuel present!
You can cheat and put a spark plug in the exhaust, hence the max power reference
