just wanted to see if i was shooting flames. let my bro drove it and followed him. at wot when he let off the car will back fire and i will see a rather good size blue flame. is this normal. the pictures i see of others shooting flames they are red and not blue. my mods: cb/dp/intakes/greddy smic/pfc at 12.5 psi oh yeah midpipe. thanks for your .02. kevin

 

mine are normally orange or yellow but I got a blue one the other day

 

Doesn't the color depend on the heat of the flame..intensity wise?

 

I was always told it depended on the mixture. The closer to complete combustion, the more blue...

 

Well flames are not all flames, i tihnk it goes yellow is the lowest heat red middle,and blue very hot. So im guessing that the blue would be the closest to over rich and lean that can shoot flames, if that makes sense.

the "more combustion" the hotter the explosion, hence the difference in color of a flame.
yes, heat is responsible for color.
if you are very rich, then obviously your "explosion" will not be "as hot" versus a little rich, which will be hotter. 2 different heats, 2 different colors

 

good stuff. thanks for all the input. maybe i am running rich. i will get on the wideband soon. thanks.

 

if you backfire blue flames is that something to be concerned about? because i have the same setup with the excetion of the ic, and i only fire blue flames and i thought my car was very rich.

ok. maybe not a backfire...more like a slight poof with the blue flames shooting out. when backed off from wot around 7k rpm. car runs strong with minor problems here and there. kevin

 

why do people back off from wot at high rpms???????????????????????????????????????????

the car doesn't like to be driven at high rpms, no car does!! you can shift at high rpms but dont just sit there and drive it at high rpms

stop doing this I don't get it
don't drive the car at high rpms or back off from wot and let the engine stoppage slow down your car
shift into the hgiher gear and press on the brake

I've seen a lot of people do this in videos and even say they do it on this forum and unless you are racing I don't see why and don't think it should be a part of normal driving
if you want to shoot a flame redline and shift hard

 

if you want to shoot a flame redline and shift hard [/B][/QUOTE]
oops that's what i meant. wot then shifiting hard. just wanted to see if i was shooting flames.

 

yeah I do that all the time too

I just don't like to see people driving the car at high rpms and letting off the throttle

flames are awesome
I have intimidated so many gay ricer boys by shooting a flame. then they totally leave you alone
