Subaru

[Fazda]

Nope, the burble comes mostly from the headers. You can get equal length headers for subarus that make them sound like any other 4-cylinder.

OK - just to get back on track here - the fact that the new WRX has direct injection does not mean that it will lose its distinctive sound.

And, no, it will never sound like just another 4 cylinder - the Boxer engine has its own distinctive sound, no matter what exhaust system you put on it.

Somehow I think the guy who works for Subaru knows a bit more than you

LoL actually I saw the interview with the head Engineer of Subaru and he explained the unequal length headers give the burble. Feel free to look it up. But it comes at the cost of efficiency so they made the headers in the new WRX symmetrical to give better performance.

Hence, no more burble. The engineer even specifically addresses this issue, and says that he thinks most drivers would rather have a faster car than a burbly one, that's why they did it. Fazda is as knowledgeable as your average salesman.

We need to understand the difference between a "burble" and the inherent differences in sound an engine makes based on its layout.

Flat and V engines have a definite rhythm to their exhaust notes that in-lines do not.

These can be emphasised or hidden by playing with the inlet and outlet sides.

None of these semantics are worth insulting your betters over.

Nope, the burble is the very distinctive sound that comes with a Subaru. Take out the asymmetrical headers and it sounds like any other car. Before you pull a Fazda, just go and look it up. It's clear as day. When the head engineer of Subaru tells you so, you know it is so.

To paraphrase, I'm sure the head engineer of Subaru knows more than a Subaru salesman somewhere in a 3rd world country

The difference in sound is due to the difference in cylinder number and firing order.
I found a great explanation as to why the subaru engine has it's burble:

The key thing to note is that while a boxer-4 does alternate firing fore and aft cylinders, it does not evenly alternate firing between its left and right cylinder banks. It cannot due to the 180 degree orientation of crankshaft pins selected for balance. So instead it must fire twice on one side and then twice on the other. And unlike an inline-4, a boxer-4 must have two separate exhaust manifolds (or expensive bulky header pipes).

One manifold exhausts [fire, fire, wait, wait] while the other side exhausts [wait, wait, fire, fire].

So in addition to the evenly spaced firing of each cylinder (just as from an inline-4) the boxer-4 has exhaust pulses exiting the left and right manifolds at half that frequency. This cadence is perceived as a half-pitch "rumble".

And why the different firing order? A flat (180 degree) engine.

Go and listen to a beetle, Porsche 356 or 914, some of the Lancias or ALFA Sud and you will hear the rhythm of a flat four.

Even better go and listen to Subaru engines in different states of tune and with different exhausts, there may be differences in their burbles but you can hear the flat 4.

Fazda will argue something to death even when he's dead wrong. Kinda what you are doing right now.The fact that Fazda went offline the moment you came online doesn't help your cause.

Brenden_E - I see that you still have a problem with anything that I say - why don't you just put me on ignore?

As for me "disappearing" - I do have a job to do, rather than sit around trying to nitpick on certain poster's threads. We also had a blackout - thank you Eskom...

You have obviously heard a BRZ with a sports exhaust? Yes?

Please note, for your edification, the BRZ has a different exhaust to the one found on an 86, and has the characteristic Subaru burble, unlike the Toyota.

Actually, I don't even know why I'm arguing this point with you, because if I had said that it sounded like a normal 4 cylinder you would be saying it had a burble.

Please put me on Ignore and have a nice day.

You suffer from selective memory. You rested your case to say that the burble comes from the boxer engine and not from the asymmetrical exhaust heads. This is untrue and the new WRX does not have the burble.

Just acknowledge it and move it.

Oh God

Get a bloody life and move on.

You opted for your trusty "screw you I was wrong but instead of realizing my error I'll just insult you instead". I really hope you aren't married. No woman deserves that.

P.S I do enjoy baiting you somewhat. Even when you are dead wrong, you either keep trying to defend a ridiculous position or when you are dead in the water you start throwing insults with your little at the end. I find the behavior fascinating. Do you do it consciously or as a force of habit?

 

[XennoX]

Holy ****, all this over what a car sounds like.

I'm ashamed to be part of the drama. But it's like rubbernecking past an accident scene, I can't help it

 

[Fazda]

Exactly!

Amazing how some people will try and do anything to win an argument..

On a combo of correctly prediction Fazda's response! So Fazda, are you married?

You have a problem.

If you know a decent shrink, I suggest you see him/her.

Mr Sour Puss, still angry I see. It was just an internet argument, not the end of the world.

So I tried to research what makes the sound and can't find a reputable source. The internet seems to say both of you are right.

Youtube 2014 wrx reviews. I think the one with the most views has a discussion with the head engineer where he speaks about it. I was just drooling over the car and happen to stumble onto it.

You'll notice the grumble is gone in the video review; sounds like a normal car.

At no point was I desperate to be "right", much as Brenden may think that I am.

The Boxer engine ( any boxer engine) has a distinctive sound.

By playing with the exhaust, most boxers can end up with some sort of rumble.

The STi rumble is peculiar to that car with a specific exhaust system fitted - it can either be accentuated or toned down, depending on what the owner can live with.

The BRZ has the same engine as the new WRX, only it is a N/A unit. With the exhaust system fitted as standard in SA, it has a very distinctive rumble - particularly when compared to the 86, which has the standard, very ordinary sounding system.

As none of us has actually heard a new WRX in "real life" we are all speculating as to what it will sound like, but the fact that it has direct injection has zero to do with what it will sound like.

The car will be here in the next 4 weeks, and then we can all make up our minds as to how it sounds, and I can almost guarantee that it will not sound like a 2005 model, as the newer models (since 08) have all sounded quieter than the original ones, unless their exhausts are modified.

Finally, the "hysteria" as to who is right and who is wrong appears to stem from one person determined to prove that he is better than me, along with name calling that has made this whole discussion degenerate into something akin to a Primary School sandpit brawl.

When I make remarks, I am not trying to prove any point or get into some pi ss ing competition. I am simply stating what I consider to be fact. If I am wrong, then so be it, however, I do resent being trolled by some immature individual who has a personal problem with me.
