Key Bangers

Post by Gem_Kid »

This is purerly a FUN ONLY thing. you cant really gain anything outta this apart from a few f*!kin good laughs and stories for your mates.

First, id like to say that i claim NO RESPONSIBILITY for YOUR or OTHERS actions whilst attempting this. YOU wear the consequences with what you do ect ect blah blah.



What are Keybangers?


Keybangers are Loud bangs that are made my excessive fuel igniting all at once. Usually Flames come out the tailpipe/end of exhaust, and a loud 'BANG' also emits.


How do i do keybangers?


Well, to do a keybanger your car needs to be running rich, not excessively but a tiny bit helps.

Firstly, when your driving down a road to your liking, turn the ignition off (only to accessories so you can still steer) and pump the accelerator. Pump it 2 times then attempt to start the car. As soon as it starts you will hear the loud 'BANG' and if you have mates behind you, They will inform you of the spark/flame out the end of your exhaust :D.

If the keybanger does not work after a few attempts then you are probably running to lean to attempt one. Enrichen your Air/Fuel mix a bit, Only a little bit at a time.

Dont enrich it too much that the engine runs crap, if you cant do keybangers at the time that your engine isn't running right, don't go any further.

Once you have enrichened it, try again. If it works then all is great. Go and have fun and eat you heart out.


Are keybangers good for my car?


No, Not Really. If anything It will harm your exhaust system. It will probably blow your muffler out if you have an old, old exhaust system.


Are Keybangers Illegal?


Most Probably. Just be careful who you do It around. You could get away with it I think by just telling the cop you didnt know what the f*#k went on, and dribble some s*#t about its your work car. Or just tell him you have had recent Timing issues and that your on your way to get it checked out now.

If you get a fine, you will probably get an Excessive Noise fine which is around $93 + the $10 Levy for Accident Victims.



Have fun trying the keybangers! :)

after u do this a couple of times u will have to come back to the "Work Shop Submissions" page and look for "Replacing an Exhaust System" :wink:

haha, im the guru of key bangs, ask any WA blokes that have cruised with me/ around me :)

couple of additions with wht u said scotty:

1) when your about to turn the ignition off, its best that you change down a gear or be past 3000 rpm for optimum loudness.

2) ask ur muffler man / do it urself and weld the muffler shut so it will never blow

3) it works best with the stock fuel pumps, as they are mechanical and will pump fuel even though ignition is off :D any otheraftermarket pumps may not do it, depending on ur wiriing...ill get a pic of it at night, i can light up the entire back behind my car orange :)

4) awesome party trick. try it going downhills, ive set off 3 car alarms in one hit in cott. also, undercover parking will set off alarms and in garages are lethal, so be careful of sensitive ears.

ive even had a homie jump to the ground, with him thinking i was doing a drive by 8)

Do you do this in gear? Can it be done in an auto?

you do it in gear, preferably going down hill. put it in gear (try to get it so the motor would be revving around 3000rpm - 5000rpm and let the cluthc out with the ignition off, the motor wqill still be turning over and ten wait 3 seconds with your foot slightly on the accelerator, then turn the car back on. :lol:

Bah not possible in an auto then, oh well. I was hoping for some keybanger flame action tonight.

could you do it with 2 stroke fuel?
i have like 10L inme shed and wanna get rid of it

Yea of course you can! Throw the whole 10L in, make sure you add another bottle of 2 stroke oil though so it lubes up the carby resonator oil supply unit, and shell be fine :wink:
Don't listen to him, he's trying to f*#k you around.
Yes that fuel will be fine BUT the 2 stroke oil could be an issue so use a bottle of FORTRON Lifter free. This is MEANT to go in with the oil and work on the lifters, but because of it's chemical balance, it cancels out the two stroke oil in fuel.

Ok, your going to run a fuel mixed with oil through a 20 year old carbie, clog your fuel filter and carbie jets and reduce the octane rating of the fuel, and increase the chances of pinging.

Personally, i would just get a heap of styrofoam and stuff it in the fuel, get enough so it goes gooey and sorta sticky. Instant napalm! 8)

Once again another guy is trying to stuff you round.

The oil will help the fuel to flow through the filter, so theres no worries there. Your carby has heaps of levers and connections and s*#t that need lubrication, so the oil will HELP more than anything, especially been 20 years old. And the jets won't create a problem by blocking, but rather, the blockage will cause a large amount of vaccuum, sucking all the s*#t through, cleaning it out thoroughly.
Fuel octane rating is one of those terms that people just use to make themselves seem big. Its actually a complete myth.
And pinging? The only pinging I've ever heard about was when my mate took an eccy.

Don't listen to these guys. Just use it man, it'll be good.

The point of an oil air separator in a turbo charged engine is to remove the oil vapour from the airstream entering the engine because it brings on early detonation. the oil effectively works like a deisel compression fuel, it enters a hot cylinder, gets compressed and heated, reaches its point of combustion and combusts, often before the spark has fired. the resulting combustion of the oil ignites the rest of the fuel air mixture before it is supposed to and causes the piston to slow down, robbing power from the engine and causing damage, otherwise known as pinging.
the same principles apply to ANY petrol engine. ever noticed how when your rings are stuffed or the valve stem seals are leaking the engine is more prone to pre ignition?
As for lubricating the carbie, thats what the fuel does, and the linkages are on the outside, if you want to oil them i would reccomend a light machine oil, like what you would use in a sewing machine, for example.
Now to the fuel filter. It is a paper mesh filter of (just for the hell of it) 50 microns. Now lets say that a small particle of oil is approximately 80 microns big, it wont fit through the filter, square peg, round hole. End result is a build up of oil over the surface of the filter, causing the eventual blockage of the filter. also, because there is an oily substance there, dirt and other particles are more likely to stick to it, causing the filter to block up even more.
As for the jets in the carb, once their blocked, thats it. there is a lack of fuel so the engine loses power and rpm, causing a drop in engine vacuum and eventually stalling, so the problem of crap in the jets will simply compound itself. And also, while the jets are blocking up, the fuel mixture will lean off, causing the engine run hotter and hotter, until you either burn the valves, or blow the head gasket, or in an extreme case, melt a hole in a piston.
Then there is the point that the engine will be burning oil, and so will make smoke, last thing you want is to get defected by the fuzz because your blowing smoke everywhere.

All of these conditions together will kill an engine very quickly, and if you don't realise what is happening you are most likely to just push the accelerator more and try and compensate for the growing lack of power, which will compound the problem more when the engine is put under more stress.

The SAE dont seem to think that the octane rating is a complete myth, neither do the chemical engineers that formulate the fuel, or the manufacturers who reccomend the minimum octane rating for their engines, or the race teams using high octane fuels so they can advance the timing and make more power before reaching the detonation threshold, which is increased proportionally to the octane rating of the fuel.

What is really scary is that you are a mechanic and you don't know this.

If i decided to stay in the industry and specialise in a particular feild, it would be high performance engines. Im nots saying i know everything, but in this case, i know more than you.

Pattis, if you want to use the fuel, its your engine, and you'll probably get away with it on a low compression engine like the gemini, depending on the percentage of oil in the fuel anyway.
