Evening all,
This maybe a chavvy question but im interested in the theory behind it, sooo I happened to come across a car meet a few weeks back where a mk6 fiesta (zs maybe) was backfiring shotgun shots even when not particularly revving it.
I know an excess of unburned fuel causes a backfire and the car in question had cheap mods so I can only assume he wasn't using after market management (omex etc).
So my question is how how would you suspect he'd done it? Can you buy chips to allow a little more fuel, advance the timing using adjustable pulley's, bigger injectors, or something else? Are there any repercussions from running more fuel other than killing the cat?
Thanks

Drive a morris minor down the road. On the over run turn the ignition off for a few seconds then back on. Instant massive back fire and a fucked silencer blown open lol.

How it's done with little to no revs answers the question - a flamer kit. Basically a spark plug in the tailpipe and a can of gas in the boot piped down into the tailpipe as well.
A switch in the cabin lets you shoot a flame out the back and revving it a little gives the illusion that it's shooting out as unburnt fuel.
Not particularly convincing and not very impressive IMHO
