nah, you get this rumble from the unequally length manifolds. I have seen Subarus with equally length ones online, and they sound very different (the 3.0 Legacys like Porsches :nod
The engine has horizontally opposed cylinders (boxer engine). Because of that the headers are of unequal length, this is what gives it the distinct sound.
I think being a fan of VW's old and new, that I would know what a boxer motor is, any tuned flat four will inevitably misfire, they are better as torque machines, not as power machines.
I doubt a lot can be worked out a lot from an engine simply from its exhaust note, other than if its making abnormal crunching, rattling or knocking noises its about to blow up.
(Unless you have some very specialist equipment and it has been known to happen in F1).
Besides there really isn't that much difference in the exhaust notes, don't let a love for People'swagens (or Subarus) cloud your judgement.
What makes a flat engine more likely to misfire/ not be so good for high power? Porsche got over 600hp out of a n/a flat engine, and it was air cooled and had a big power sapping fan.
Sorry Bluey, but your VagFagness is showing through again. It is purely the big exhausts that are commonly fitted to Subaru Imprezas which give it that burble.
My Brother had a Prodrive exhaust fitted to his old GC8, and while it sounded very nice, it did not have such a distinct burble as the videos posted above, and the car was timed up perfectly.
Porsches don't sound interesting at all. One of the dullest engine sounds ever.
And how can you possible like Beetles, but dislike EVERY Ford? Have you not taste?
You've gone for a long time without trying to talk about how engines work, and then you come out with that nonsense about them being timed badly? Obviously you haven't spent the last year reading "My first illustrated book of car engines"...
Beetle is most popular car for a reason, because it is good. Ford's are popular, because the home country is America, and there are also more stupid people in the world than smart.
Just why does Ford being based in America have anything to do with it's popularity in the world? and I thought being American-made was a "bad thing" these days...
What you said doesn't really make sense when taken that way either.
On topic: one of the best on-board videos I have ever seen. Wheel-to-wheel racing for the entire 15 minutes (2 parts) between some very, very fast drivers.
Formula V is grand, remember one event I went to the Irish championship had come over, they all got hammered the night before and in the race the next morning every car in the field left the track on the exit of T1, the same thing happened for about 4 laps.
