Possible way of making LFS cars backfire.

[Foliage]

Hey I've got an idea but Im not very good at sound editing so maybe one of yoou guys could give it a whirl.

Anyway with the turbo cars take the blowoff noise and then add backfires after it for say 10 seconds, so say if you rev the motor out and then throttle off it will pop and crackle and stop as you get back on the throttle. I know it won't be rev dependant but I think it could sound pretty cool.

Do you guys think this would be possible?

[Lible]

Well, i believe it is possible, but it's pretty hard to do tought. Anyway, i really can't see the point of this... do F1 cars have backfire... no, but Nascar cars? (well, don't ask me :D)

[Galthar]

backfire is a cool effect. Especially seen on WRC cars... It is amazing sometimes. And I think backfires have all kind of racing cars... GTR, WRC, GT. I dont know anything about a reason why this effect does exitst but it is cool ... ;)

[eindewege]

Well, there was a thread running in Improvement Suggestions, which was about backfire being useful for the turbocharged GTR's. It would be useful for charging the turbo again quickly after you let go of the throttle.

F1's have ocassionally backfire, not much, but there is a little.

Every hard tuned engine which runs a little rich backfires.

[Citywidemicke]

I dont think backfire shuld be in LFS at all. Have u see UF1 with backfire ? yes only on movie :nod:

Well the backfire as itself is just and effect. Nice to have where it realistically should be. I don't think there is any precise reason why UF1 should not backfire under certain conditions? No catalysator, etc...

[SamH]

Long-term, I don't see why LFS wouldn't have backfiring cars. Obviously not all of them, but GTR class cars do backfire occasionally if the fuel mixture is rich. F1 cars do but only very occasionally, as nErU pointed out. UF1000 probably wouldn't, under most normal situations.

Eventually what is real will be simulated in LFS. One thing though.. this is LFS we're talking.. don't expect to see it until it can be done PROPERLY.. and that won't happen until car setups include engine tuning. That aspect of motorsport I don't think we'll see until S3.

But expect it then!

[Foliage]

Yeah I didnt mean for it to be realistic I just wanted someone to try it with the bov noise so the turbo cars crackle a bit. Thought it would be a nice wanky sound effect. :)

[sturje]

problem with this itd happen EVERY time you shift. Nice idea, but i rly wudnt want to hear the car backfire everytime i shift, itd get a tad bit annoying. Ill leave it to the devs to implement at a later stage :thumb:

[Liquid Li0n]

Not every car must have backfire, only the GT cars for example would be cool to have it. It brings the realism higher

[chopaholic]

If someone can get a decent backfire noise i cud try it :)

[wheel4hummer]

There needs to be a misfire sound effect, when you are running out of gas for example. NOT backfiring though.

[Ricerguy]

uuh guys its called a anti-lag system (ALS) and the way that turbo in the XRT is workin it needs one horribly the als boosts the turbo and stop it from taking so long to charge up and depending on the car u get a varying sound effect if u want loud get one for your subaru :P

[polyy]

in xrt is possible backfire??

[Primoz]

I dont think backfire shuld be in LFS at all. Have u see UF1 with backfire ? yes only on movie :nod:
Backfire != ALS :chairs:

As said, even F1 cars can have a backfire, but they're not running turbohargers, are they? No. WRC cars on the other hand pop EVERY time the driver lifts off (well, most of the time :) ). That's becausr they have antilag and the backfire is THE thing that makes spining the turbo (the air/gas mixture literaly explodes in the exhaust). A simple backfire is an accident if you will.

Well the backfire as itself is just and effect. Nice to have where it realistically should be. I don't think there is any precise reason why UF1 should not backfire under certain conditions? No catalysator, etc...

Hyperactive thinking of an UFR maybe? :)

Wouldn't a misfire come too llate? :) I mean, you could get it near the pits, but say, 100m after Aston GP finish line, a tad late, don't you think? :D

insim app to make it happen? At least the sound...

[xaotik]

Yeah, now with Outgauge this and new turbo sounds/blow off valves and all the other audiocandy (random rattles at high speeds, etc) are totally feasible.

So it would be possible to have transmission noises, plus other sounds, like going over curb too agressively, flatspot sound (?), etc.

Kegetys...? :D

Transmission sounds sure. Bump noises from hitting curbs could possibly be done using Outsim (which has been around for some time) too. But flatspot sounds are a no go, there is no output of tyre-related data.

But if the flatspot changes the tyre form (if it does in LFS), making the tyre "octagonal", it should affect to the suspension... But I guess it would be quite hard to make it work right :)

Primoz knows the score :thumb:

I'm only a demo racer but i'll put my 2c in regardless.

I think backfire would get annoying unless it's random. Can you imagine if it popped EVERY time you lifted the throttle? Yikes!

Is it possible to get the backfire running a looped sound file (with random inserts of the sound) while only on decel? So not when you instantly lift the throttle, but while the car is revving down, as it would be normally (not taking anti-lag into consideration there... but i don't think any of the cars in LFS have anti-lag do they? :P )

Cheers:)

[z323]

Hello 7TH, ;)

I love watching the V8 Supercars because of the backfire they produce. :D
I like that idea Shinanigans, but surely it would get annoying even if it only happened when revving down, as I do that alot because I'm a slow drifter, which means I'd just here backfiring alot of the time.

Are you kidding????? F1 cars backfire whenever they lift off the throttle! Sure, flames don't shoot out the exhaust pipe, but you can definately hear it. I was at the USGP, and we sat at the end of the back straight, hearing the cars backfire under braking was very cool. The BMWs backfired the most, and the Honda's the least, but they all did it.

[wheel4hummer]

Nascars backfire. Ive seen them do it on the road courses. But, cars never really backfire on a big oval.

[kiss me]

a bit late for me to post here...
but have u ever seen a car crash at 220kph and still beeing able to drive??
:p

[indo420]

well i'd think every car backfires at some point. My buddy took the catalytic converter out of his Honda. It back fires a whole hell of alot now.

[tristancliffe]

Did he rewire the catalyst temperature sensor, or is the ECU under the impression it's not warming up, and over/under fueling to try and compensate? But no car made in the last 10 years should backfire as it would automatically mean it would fail emissions tests and wreck economy.

You take the restrictive sound deadening exhaust off, and you'll hear it everytime you go from wot to 0 throttle on any vehical bud. Its not possible to go to 14.7 A/F when you let off.

[Knight_Atack]

F1 cars definately backfires. Maybe they do a bit less, but they used to. Here's the 1999 BAR backfiring slowing down at Monza :D (Click here (http://www.farzadsf1gallery.com/f1_sounds/ascari2.wav) (don't mind all the characters, just listen)) Like said before, there's no big fire stuff... well... sometimes we can see it... lol... But anyways. Backfire sound would be good for some cars... Like the GTRs... But that's all really... And I don't think it would have all that much point. :shrug:

[Shinanigans]

Sure, when you change your exhaust you will notice the backfire. But i think what Tristan's point was (correct me if i'm wrong Tristan) that in changing the exhaust, you are also putting the car under the same category of those that would "fail the emissions test". i.e; if it pops, then it fails emissions.

That being said, you don't need to remove a cat converter to make your exhaust pop, all my cars with aftermarket exhausts have popped on decel.

But this is all a little off topic. I personally like the idea of backfiring in LFS, but only on decel, and only from GTR type vehicles and possibly the option to turn it on/off in the options.

[Shinanigans]

^^ that's a HUGE backfire! Love it! :D

Nah, there isn't any point to the cars backfiring in the game, it's just an aesthetically pleasing contribution to realism. Theres 1000 things that are more important, but if it's an easy thing to do, then i think there are a few LFS players out there who would find this kinda thing really appealing. :thumb:

[wheel4hummer]

But when it comes to for example formula 1 cars, they have to pit, and so they have to build their engines so that it doesnt waste petrol like rally cars do.

Don't F1 cars get about 4MPG? And, if you took off the catalayic converters, then you have to rewire the O2 sensors, or put them up in the headers I think.

[BoGGis]

Well, not all cars have backfire. When a car backfires, its a sign that it gets to much petrol. commonly this aint a problem (rally, Rallycross etc.) But when it comes to for example formula 1 cars, they have to pit, and so they have to build their engines so that it doesnt waste petrol like rally cars do.

so, now you know :thumb:

[Kris-Is-Awesome]

I'd like to see backfires- where appropriate(sp?). GT4 implemented them, but they are in every car, and occour in every shift. It's horrible.

I'd want some of the higher powered- racing cars to backfire- on downshifts. With the flameout. Cars don't tend to backfire on upshifts.

THAT is how I want LFS to sound. Like a real friggin car!

I have Seen a bone stock RSX/Integra Type S backfire.

[ElBoss]

Hi people...
Sorry for my bad english...
If the LFS can not make backfires, why not (for testing) one pro on making .raw files, make one sound for blowoff sound of turbos, like ( POUUM pumpum ), so when you drive the car from inside, it look's like a backfire...
can anyone make this sound for testing? i like it...
Thanks...

[DTrott]

I assume your talking about when the throttle is let up on heavily tuned cars when unburnt fuel burns at the end of the exhaust with a crackle noise. It would be nice on GTR cars as it has quite often and only occasionally with F1 cars.

:thumb: Hell yeah.
ive seen that vid earlier too and again i have to submit thats the kind of sound that i want.
alot ppl will come.
dang all cars sound like ricers then~~
lol idc, its awesome sound.
played the rfactor demo physics crap but loved the engine sound.
such an engine sound would be an huge improvement and raise the driving
fun +300%

[ElBoss]

I just tried make a sound for blow off turbo , like: PUM! PUM! on "Sound Forge 8.0", but the sound stay like ppffum pfuumm...
Please make one sound like this...
sorry my bad english :smileypul

[Foliage]

LOL

thats just the sound of a skyline dubbed over the top thats not s3 and thats not how its going to sound.

However itd be awesome if it did sound like that.

[ajp71]

Well done Einstein we all know that :uglyhamme

[hrtburnout]

Maybe, a temporary solution could be making the BOV sound like backfire, but ofcourse that wouldn't be completely realistic.

i think it´s a good temporary solution...
