Flames,and Back firing
 

Ok i want my car to backfire on downshift and shoot flames out of the back, how can i accomplish this? its a d16a6, i just thought it would be cool to be able to have this feature

Re:Flames,and Back firing
 

uhm a backfire isnt what u call good.

to get flames out the exhaust run some big ass injectors and run your car rich as hell!

Re:Flames,and Back firing
 

you'll probably waste your cat so you might as well run a testpipe. wouldn't nec recommend it though.

Re:Flames,and Back firing
 

the real way to make your car shoot flames is too put a spark plug about 3" inside youe exhaust tip then wire it to a coil so it sparks constantly. Truthfuly its more wiring hassle then anything. but if you want it can be done.

oh the spark plug is goin to be igniting the unburned gasses in the exhaust.

Re:Flames,and Back firing
 

My uncle did this as a joke on an old datsun 280z. He had a small propane tank in the trunk that ran through the exhaust with a spark plug near the end. He had it controlled with a switch on the dash. It was amusing when I was a kid, but I think it would be a good idea for ppl who ride your ass on the road.

Re:Flames,and Back firing
 

dont the rally guys use a missfire system one there cars?
it makes a big bang like a backfire and flames come out.i think that is more for performance then looks but who knows.

i might be wrong!
but i thought i would say something.lol

Re:Flames,and Back firing
 

Any explosion in your exhaust can create a grenade out of your muffler.. This is BAD!

The old muscle cars used to do it by reving it up until the muffler loads up with rich fuel. then being ignited by an extra spark plug skrewed into the pipe.. These things hurt people!! Be carefull dicking around with it! its not the explosion but the flying sheet metal thatl get ya.

Re:Flames,and Back firing
 

I dont know if this guy wants a flame thrower or just for the exhaust to shoot out blue flame.... One time I was at the light and a black 3000Z pulled up and he reved his ----... and so did I... and then he was ------- around with a monitor in the car... when the light turned green his ass was gone.... and a small blue flame shot out the back of that mofo.... damn it was sweet.... not like the fast and the furiouse (those shits were flame throwers...) but im guessing this dude bumped up his fuel and ignition a notch just to whip my ass... it was fuckn sweet...

Wouldnt backfiring with a fucked up PCV valve ---- up your piston rings???? dont know why this guy would want to backfire on purpose....

Re:Flames,and Back firing
 

he wasnt backfiring man! ok i consider a back fire when fire goes backwards through the engine IE through the intake. when your timing is 180 degrees off.

now fire shooting out his exhaust has to do with his fuel mixture and how much gas is present in the exhaust system. it is ignited because of the high temps through the exhaust when your pushing your car very hard.

i see alot of rx7 who have serious hp popping out flames al the time. plus the rx7 exhaust gases are way higher then any other car..

Re:Flames,and Back firing
 

ok retards, you're all wrong. :P

let me clear this up.

when cars sound like they're backfiring. they're hitting a rev limiter. the reason SOMETIMES flames come out the back of the exhaust is because all the gas that didn't get burned ignites in the exhaust. the rev limiter stops the spark and the gas never gets lit in the chamber.

Re:Flames,and Back firing
 

I run my car very rich and retarded the timing, to prevent detonation, and I can make my car backfire whenever I want. I try not to do it so I don't blow up the muffler or burn my exhaust valves.
Easiest way to do it is to run rich(floor the pedal) and then turn off your car and then back on again, works for me everytime.
Don't know why you would want to do this though.

Re:Flames,and Back firing
 

Actually Hondas/Acuras use Fuel Cutoff for a rev limit, not spark.

And if you really want some cool backfiring, just take your screw off of your distributor rotor and go drive it around.. right Beau? ;)

jeff i mean to ask you this everyday
whats your avatar...

is that your wife or something?
or you dressed like a shemale?

Re:Flames,and Back firing
 

yeah but i've seen hondas with aftermarket clutch cuts or something, they use spark to limit rpm. i seen a turbo geo prizm at woodburn dragstrip. it used a spark rev limiter and it shot sparks out the exhaust.

and who the ---- is shaniqua. lol

Re:Flames,and Back firing
 

i cringe every time i see that avatar jeff.... :-\

as for the flames, a buddy of mine has an rx7 turboII and with a stock engine no mods he can shoot flames simply by shifting at redline. its crazy cool to see at night when yer getting spanked by him in your dx ;D

Re:Flames,and Back firing
 

Re:Flames,and Back firing
 

blech!! :-X lol!!

Re:Flames,and Back firing
 

this forum is so funny....well homemade turbo in general is funny. you would never see people talking about a black cross dresser and its secret packages at crx resource. AHH MAN! you gotta love this place! ;D

Re:Flames,and Back firing
 

yeah this forum does kick ass, now what was that about installing a spark plug 3" in my echaust tip? can someone show me how to do this, i really want my car to have a flame come out from time to time.

Re:Flames,and Back firing
 

drill a hole, thread a spark plug in, run a wire to a switch, then to the battery
would that work?

Re:Flames,and Back firing
 

buy a cheap ignition coil... hook it up to a switch..... put a kill switch on your current ignition coil (make a switch box and put the 2 switches right next to each other)... wire the cheap coil to your spark plug on your exhaust... spark side of the plug must be aiming towards the top if you mount it on the bottom... gut your cat..... now warm up your engine a bit...... make sure theres no one behind you...
rev that bitch up real high... and press and hold both switches at the same time.... and happy fourth of july...

In theory: your car is running, and you rev it... more fuel gets injected as your reving... then you sudenlly kill the ignition.. fuel is still beeing injected and then expelled by the piston as the engine is still rotating... the pressure of the pistons will force the gas out through the tailpipe with force with the ignition still off press the button to activate the sparkplug and when the fuel exits the pipe the spark should light it up.

ps... for best results make sure you muffler is grounded well... and try to kill your ignition before activating the exhaust spark..... as to allow the pistons to force the unburnt gas out of the exhaust...

Re:Flames,and Back firing
 

this is how the plug should be installed on the exhaust tip

if you need more info just ask...

this is for a flamethrower on a car... they sell these kits online... but you can make your own if you have some creativity and spare parts lying around....

Re:Flames,and Back firing
 

the pic is not showing.

Re:Flames,and Back firing
 

ok it should be showing now... any further questions just feel free to ask

Re:Flames,and Back firing
 

sweet, can i place the spark plug just behind the muffler, its a nice muffler i have on it and i dont want to ruin it.

Re:Flames,and Back firing
 

well i hate to tell you this but your gonna have to drill a hole on your exhaust tip thats big enough to fit the screw side of a spark plug.... its best if you mount the spark plug as close as you can get it to the exhaust outlet... this way it will light it up easier... (just like when you get a lighter and hairspray... it seams to make a bigger flame when you put it right next to the nozzle as apposed to a few inches away) i got this idea from reading some anarchy posts a while back... they say its nice to have when people are ------- with you while your driving (tailgaters) personally i prefer carrying a brick in the car... its amazing what a brick will do to someones radiator at 80MpH...

Re:Flames,and Back firing
 

here guys enjoy =)

fully built NA b18c1 with toda spec b's

http://www3.sympatico.ca/h.leung/Car...egbackfire.mpg

i've been there when he downshifts.. for some reason when he downshifts it backfires like a MOFO and sounds like an ak47 and shoots flames... really cool!!!

his car is NA btw =) 14.6:1 CR on 94 gas... such a monster.. it idles like a v8

Re:Flames,and Back firing
 

el linko no worko... my friendo....

fix it this no problem eh????

Re:Flames,and Back firing
 

so do those flamethrowe kits they sell disable your distributor that is in you engine bay and then activate the one hooked to your exhaust?

b/c my friend had a kit on his old carb truck. all he did to shoot flames was pull the choke and flip on the sparkplugs in his exhaust, he could get 4-5 foot flames... i dont think you would want to run your honda rich enuf to make flames like that.

I have seen vids of supras and other cars that just shoot flames when they shift, is it just from high compression ratios??

Re:Flames,and Back firing
 

guys i'm not trying to build a flame thrower, i just want a small blue flame to come out when i shift or downshitf.

Re:Flames,and Back firing
 

buy a cheap ignition coil... hook it up to a switch..... put a kill switch on your current ignition coil (make a switch box and put the 2 switches right next to each other)... wire the cheap coil to your spark plug on your exhaust... spark side of the plug must be aiming towards the top if you mount it on the bottom... gut your cat..... now warm up your engine a bit...... make sure theres no one behind you...
rev that bitch up real high... and press and hold both switches at the same time.... and happy fourth of july...
but could you not just get a coil and just wire it to 12v with a switch and just run your car rich and not need to shut the car off?

Re:Flames,and Back firing
 

yeah i dont wanna have to be shutting the car off, i want the flame to come out while driving down the road, or reving in the parking lot at an autoclub meet

Re:Flames,and Back firing
 

i got the movie by saving target as, but it doesnt sound too good when the flames come out

Re:Flames,and Back firing
 

think about it... the camera is in a SiR tailing the GSR...

i was standing beside him when he was pulling out and he shot a flame out... people started to duck around us thinking it was a drive by

it's crazier in person =)
