GT3, how to get the backfire pop sounds?

[NairBoT]

The GT3 cars have the backfire flames.
Also, with CSP there is the newer flame which is nice.

However, I never hear any sound to go with the flames.
I hear the gear shifting and engine but nothing specific to the flames.

Shouldn't there be a pop and/or crackling sound that happens along with the flames?

NOTE: I also have the game on console and there is no backfire sound there either.
So it's not something included with vanilla game.

To me, it seems like a major oversight considering all the mods available for this game.
Nobody thought that the muted flames was an issue? wtf

I did a google search for real life GT3 cars and this is the result:

"Yes, when a GT3 car shoots flames from its exhaust, there is usually a distinct sound accompanying the visual effect, often described as a loud "pop" or "backfire" sound, which is caused by the unburnt fuel igniting in the exhaust system as it exits the tailpipe; this sound is a key characteristic of the flame phenomenon."

You haven't been around them have yah? To make life easy just got to UTube and google GT3 testing and tell me how many cars you hear the backfire on (or see flames)?

Here is a link to a porsche. ..enjoy..... https://www.youtube.com/watch?v=IAk31nL2Nv4

AC could use better sound design but modern backfire = it has been tuned in a shed.

There is backfire from engine running rich, having fuel collect over time in exhaust and produce bang when supplied with air under braking, and there is controlled release of fuel that ignites every rotation, continously producing flame with no noise.

Whether a car actually made loud pops, barely audiable exhaust note change or no additional sound with flame will change from case to case. Heck even on one car this can change from race to race as fuel limits dictate how much power you can gain by cooling the engine with fuel... But generally younger generations will have less audiable pop, if at all...

WOW, 3000 hours played and 10,000 hours played.

You both schooled me but I was hoping there was a way to get the pop sounds.

Thanks for the replies :)

I mean you can mod the cars and make exhaust pop louder, longer, add it where its missing etc. Thou im not good at sound modding, heck i dont even drive gt3s anymore... so cant remember how much is audiable.

I think the individual pop that you can hear on old cars, thats connected to the flames is removed (on purpose) for modern cars and instead the pop happens in the coast audio - so you'd have to add it to the .bank file from somewhere (there are tutorials how to do it)

This coast pop is the controlled, "continous" fuel burn, which usually happens inside the exhaust and the flame is short enough to be contained within the tailpipe. When you see flames its just same thing but there was not enough air to burn the fuel fast enough before it got to the exit. But not much should change with how it sounds.

Also importantly, these days they make sure fuel is ignited with a conflagration rather than detonation, which has different flame and sound. Detonation produces flamefront that "brakes the sound barrier" and thats the pop you hear. Conflagration has flamefront slower and no "pop" from flame itself, but it can still affect exhaust speed in the pipe creating extra sound, just not as loud.
And ofc with enough fuel in the exhaust both burn types can happen together.

Fun fact: in a cylinder: conflagration is normal fuel burn, detonation can happen if fuel is preignited through a hotspot and will destroy piston/valves/head after a bit).
