I really like the concept of having backfiring in GT4. However, it seems as though 1 of every 3 screenshots I see shows a car backfiring. I'm hoping this is just because it is a really neat effect and people want to capture it to show the rest of us. But can anyone with the game shed light on exactly how highly a car must be tuned before backfires will occur? Also, can ALL cars backfire? I ask this because I would find it out of place if a VW New Beetle, even at Maximum power, could spit fire as this would be a highly unlikely event in the real world.

I think this is an awesome addition for all of the race cars in the game, and it even has a place with certain highly tuned road cars. I'm really hoping, though, that it this feature is limited to performance-oriented cars and even then only with a Stage 3/4 Turbo, Stage 3 NA Tune with all other engine mods, etc. And please tell me that no street car in the game will backfire in stock form. I'm just assuming this won't happen.

What are your thoughts, and can any info be provided by those who are lucky enough to have the game? Thanks.

P.S. - In all fairness, the Daimler and Benz motor carriages and the Ford Model T should also have this feature, as it naturally occurred on these models as well. :D

Welcome to GTP. ;) Most weak-ish stock cars should not backfire, and well as anything beneath racing level. Thus far the only backfire pics that I have seen involve GT500 Cup autos or similar fire-breathers. And yeah, it would be nice to see antiques backfiring... with ngine failure! Not. Anyways, if you dig around there is already a thread concerning backfire.
 
You'd be surprised. A WRX (not STI) with an atmospheric blow off valve and a catless exhaust can shoot a fair amount of flames.

It actually doesn't take a whle lot of modification in real life to make a car spit fire, a 1.8t Beetle wouldn't have a hard time with a few carefully chosen modifications, at maximum power it could be flaming more than Elton John. The RSi Beetle... that goes without saying, a twin turbo VR6 in anything is a beast.
 
I am noticing that many of the cars in GT4 will spit fire. Even some of the stock ones. (Especially RX-7s, but then again, they are known to do it)
 
Mister E
I'm gonna go out on a whim and say cars with race exhausts (catless) will backfire.

That's a very good point. Hadn't even thought of that. You're right, a straight-thru racing pipe would make backfires much more believeable in-game than a full factory exahust.
 
Depending on the car, I would think it could be possible anywhere. I think the reason we're seeing so much of it in these pictures is that people are still in "wow" mode, that backfire is the coolest thing since sliced bread. Give it time, it should wear off.

The only car I think I'll enjoy seeing backfire on is the Pagani Zonda. Because of the position of the exhaust (dead-center on the back of the car), I always thought it looked a bit like a "rocket car" (my personal nickname for the Zonda). Now it can be.. hehe. But even there, it's just a gimmick. While it is a real phenomenon that happens quite often on the track, it's still just a gimmick when it comes to the photographs. As for the Photo Mode pics I'll be taking.. I couldn't care less.
 
My brother's R33 gtst got an exhaust pop in its stock form (BOV thats it) but we had to rev it pretty high about 7000 rpm in first gear to get it. After we installed a catback exhaust the exhaust pops were more frequent even at lower RPM's. Can someone tell me whether or not when we get an pop whether or not there is a flash or something or is it just noise?
 
I think there's a pop too.

Atmospheric blow off valves (usually the ones fitted because of the "awesome" sound) help to create backfire. The MAF reads how much air is coming into the engine, and adjusts the air fuel ratio accordingly. When you release a lot of the air, as in an atmospheric blow off valve, the air lost isn't calculated. This leads to a temporarily overly rich fuel ratio, which puts unburnt fuel into the exhaust, and boom, you've got your backfire, assuming there are no cats in its way. Stock and recirculating blow off valves release excess air back into the airbox, and therefore don't create these rich conditions.
 
From what I've seen and read, backfires only occur when downshifting and slowing down. In real life, they can and do occur when upshifting and would have been nice to have it in the game.

Also, It would be good if not all cars backfired. (ie only mildly modified turbo ones or highly modified NA cars could at the least).
 
thanks for the info on turbos. I'm not real knowledgable in the area of turbos. I guess I'd be more willing to see backfires on less highly-modded cars now. plus, the effect is really neat. Bring on the flames.
 
ther'es backfire and there's afterfire. if u are getting popping noises but not kaboom backfire (like a gunshot) its normal after installing a catback.
 
I'd expect quite a bit of backfire from the GT cars. I witnessed firsthand the fact that those cars backfire just about any time the driver lets off the throtte.
 
If you guys ever watch any sort of auto-racing, you will notice that backfiring happens quite often.

It happens on jsut about any car with high fuel depands, and advanced timing. As soon as you lift off the throttle, it will go rich, and backfire. It happens reguardless of the size of the engine, or weither its NA or FI.

And can happen in anything from an Echo to a Evo.




What i would really like to see in the GT series is properly modeled turbo lag, and the ability to get anti-lag installed. That would be a backfire worth having.

My R33 Skyline GTS25t with a catback exhaust, cold air intake and some other things also makes the loud exhaust pops, no flames are expelled intill you remove your cat, then you will get big flames.
 
Thats true. If you ever see a v8 supercar race, you'd know what flamage is all about. It occurs when the throttle is shut but the mixture that enters the engine isnt burned propely as its very low revs and the engine is under vacume conditions. Most the the gas that goes into the red hot exhaust is still unburned and ignites in the exhaust.
 
actually i think GT4 had done a good job for backfire
unlike other games which back fire for every downshift

GT4 is like it backfire when it has to be. And turn up the speaker, you can hear the sound of the flame coming out, so cool.

And I am not sure about how many modification you have to make in order to make it back fire, but I believe has to make some modification to NA car to make it backfire (just like real car), but for turbo, I had a stock Evo 8 MR, it backfires a lot
 
engine sound
i think i improves a lot, as i am driving a DC2R with stage 1 NA mod
the sounds just like the real B18C engine with an N1 exhaust
but the bad part is, they still don't have the vtec switch over tone
