Backfiring, bang bang

[Rufes1]

Hey hey
well the other day i saw a nice plain sprinter in a car park hold it in first, compression brake to slow down to a speed hump, and see this flame pop out for a split second, like a flash and a big bang.

Talking to a mechanic friend of mine he mentioned a technique called key banging it... Tried this where u boot it in 2nd or third, keep ur foot down and at about 3 - 4k switch off the ignition, give the pedal a pump then flick it back on.

I got little bangs, granny farts compared to the one this sprinter did. I think the sprinter had the original engine in it.

I have an 89 civic, dual carb .. just wondering if n e one knows other techniques to get a big bang, but none of this spark plug in the exhaust rice business...

Lol, how do u get urs to go bang?

IF you own a carby car ( or are just driving one...and are up for 3 secodns of fun ) sit in hte car whilst it is off - and pump the accellerator many-a-time.

Then...turn the ignition.

Should result in a HUGE ass oily big bang ! :P

BTW dont do this.

[tofu R]

hahahaha buy my exhaust ? =P and ull know

[madgrk]

Buy a supercar :? WDF would you wanna backfire your car for man?!? Oh well whatever floats ya boat I guess

People try to prevent backfire, not try to cause it!
Why do you want to cause your car to backfire anyway?

[CTR Coupe]

dont you know a missfiring system makes it go faster :P LOL
key bangers are really bad for the car. if u want to pop flames just get a rotary :roll:
on a side note i saw an excel with one of those sparkplug jobs it had a 2F2F style 1ft blue flame for about 30 seconds

Yeh that's right...that extra kick of black smoke gives you that extra push in the opposite direction right!

[[[d a n n y]]]

Rufes1: why would you want your car to backfire? just coz its in "unrealistic" Fast and Furious dosent mean its good. If a car backfires as much as you say it did, then thats VERY BAD i know that. Happens mostly on old cars, but dont try and do it, unless you can afford rebuilding your engine.

my mate managed to blow the crap out of an exhaust on a van doing a key banger. Basically he turned it off while going down a hill quite fast, causing a rather large amount of fuel to get into the exhaust.

When it turned on there was a huge bang and bits of exhaust were everywhere

Would work better on cars without cats as well
