How do they occur and does your car have to be turbos.....common people fill me in here



thanx in advance

All you need is a open exhaust (No cats or mufflers) Just straight through and a rotary will shoot flames. It doesnt have to be turbo infact NA's do it easier that turbos (the turbine is a restircion)

you mean somehting like this right? keep in mind that my camera takes about 5 seconds til it shoots, and i saw it, and took a picture



downpipe,midpipe,catback a lot of boost, stock ecu, and a heavy foot



ask teknics, thats his car

TII777 11-02-2003 12:57 AM

actually turbo engine cars are more common to shoot flames, but the only 7's that i see shoot flames are labeled as "hott boyz"/ rice boyz

teknics 11-02-2003 01:18 AM

ok thats my car fikse posted.



I have a complete straight exhaust, running high boost, and the car is running really rich (no i have no idea why, it's the stock ecu and stock injectors, i think my o2 sensor is fubar and im running in open loop mode which would cause richness...but no check engine light pops on so who knows.



N/A's shoot flames as well, all thats really neded is a straight exhaust and rich mixture.



Oh and another way is to take the dashpot off of the throttle body assembly, it slows down the speed at which your tb closes, when removed then whenever you take foot off the gas after having the throttle pretty open (which is when flames shoot) the butterflies inside will snap shut without resistance which makes for good fireworks...my car has no dashpot and the flames have shot a lot more without it on there, plus no one has mentioned why no dashpot would be bad so it works for me https://www.nopistons.com/forums/pub...IR#>/smile.png.



edit: oh and a lot of times you arent going to hear anything, unless it's a quick high rev then let off gas and let it compression brake, thats when i hear pops and shoot flames. But when I'm normally driving it just shoots flames constantly when i accelerate even a bit then get off the gas, but i hear no sound.

na's pop and spit fire, like chainsawonsteriods's (leo) car. He set his TPS for overrun or decel fuel and i did the same and we shoot good, blue fire

how do you install that coil spark plug thing exactly

FikseRxSeven 11-02-2003 03:51 PM

mount the sparkplug on the exhaust.... and if you're running rich(like i am) it will be a flame thrower.



im not sure if that car is doin that, but i love the blue flame
