I'm fairly sure I know where you live, work and what you look like.

I just took your name on here (if that is your real name, it may well not be), some information I have gleaned from your previous posts and googled the st out of it.

I was interested to see what you drive, whilst looking at your profile I clocked that it was probably your real name on your profile (always a bad idea) and decided to do a little digging through your previous posts to see if I could figure out the vehicle you choose to call your own. From there google really did do all the rest.

I have no actual interest in any of this information, it means nothing to me. It may even have thrown up false results, so I may be wrong too

Ok, as a little exercise, I'd be keen to know what you've found, just to see how accurate you've been able to be.

You know my username but I'll be more than happy to give you my email address for this.

If you would seriously like to know what I found then please feel free to PM me, as I said I am more than likely wrong.

Tbh, there are far better sleuths than I on here that could probably tell you what you had for lunch. Anybody remember the name of that thread where people were locating where photos were taken from the exif data and even more complicated methods?

If I could work out how to pm using my phone and the mobile site, I would

I find the reaction to this a bit sad. I mean 220bhp is 220bhp no matter the engine size. As long as the cars built around these engines go well i couldnt care if my 220bhp came from a 3.0 6pot or a1.5 3pot turbo.

[Hellbound]

Weird thread about an engine.

I wonder what happens at these PH meets. I like to think, after some posturing, you all start kicking each other in the shins.

Not interested in sound or power delivery then?

[The Obeast]

Not many cars sound amazing from the factory anyway, and as for power delivery none of us have driven a car with these higher output engines to be able to talk about how they drive.

True, but plenty of us has driven other manufaturer's offerings in this sort of market and have driven BMW's current and past turbocharged engines and consider that they have horrible power delivery, so it's a good bet that this will be similar.

You believe in those numbers , you believe.

The current engines have trouble dragging fatty so what do you think will happen?

The engines have to produce those numbers or the entire world can sue BMW. I suggest you get your lawyers ready if you genuinely think the numbers you clearly don't understand are wrong. Nice little earner.

And yes, a new 315 will be exactly as slow as a 325 would be. How will people cope?

I understand the numbers just fine friend and thats not where we differ, what I dont believe in is miracles, that is a different thing entirely. I see it like the comedy BMW CLAIMED MPG, an utter load of old bks.
So, Ill believe it when I see it.
Surely after this impossible marvel the next unit will be a KERS induced Ion propulsion drive and it will run for 1p per millenium?
But theres plenty people ready to fall for this comedy without me needing to join in isnt there.

[kambites]

Interesting, I've never seen any particular evidence to doubt BMW's power figures.

i understand your point, but too many people writing off an engine we havent tried yet is a bit over the top. If the way engines are configured has to change, then small capacity turbos are surely better than batteries?

I'd prefer batteries and electric motors myself, as and when they become properly viable. Much better "throttle" response and a nice linear power delivery.

I was going for an exaggerated rage with that one, little bit of tongue in cheek, although I was pretty wound up

Quite like the Volvo and the 328 btw

Having read your comments in this thread and the "BMW to buy De Tomaso" thread I can only come to the conclusion that you were raped by a 325i at some point in your life.

Your apparent hatred for BMW is quite frankly bizarre.

I'm not sure if you're 15, have an IQ of 15, or are simply trying to provoke reactions off people.

BMW has also fitted a torsional vibration damper to reduce the innate vibrations of a three-cylinder engine.

So just like the TV dampers that engines all have already then?

Or something new and interesting?

I'm sure you wouldn't have mentioned it if it wasn't new and interesting, in which case I'd like to hear more about it please.

If they just mean balancer shaft then for a 3 cylinder, while its not necessary if the engine is small enough, its a bit simpler than what is required to sort out a 4 cylinder. In a 4 you need 2 shafts, in a 3 and a 5 you only need one to sort out the end to end vibration of the engine. This sorts out secondary harmonics, primary harmonics are done by the counter weights on the crank.

that right there is a great website for getting familiar with how to make engines smooth.

I think it is fantastic............as soon as they bolt the other half onto the front and make it a straight 6 twin turbo. Wait a minute, haven't we been here before?

...not with ~450bhp and astronomical mpg figures! Makes you wonder what BMW have planned. The N55 has reportedly reached its peak (hitting 320bhp and 38mpg in the M135i). What about this for the N56?

If they glue two of these together, which would probably fit in a similar-sized space to the N55, they could do clever stuff with timing and turbos that you just couldn't do with a single-block engine. How about deactivating half the engine to "only" give you 220bhp when you're pootling about town or cruising on the M4?

Will BMW do this? Probably not anytime soon. Should they? Heall yeah!

[kambites]

I've often wondered about this. No-one has yet managed to fully deactivate half of an engine. You'd need a clutch in the middle of the crank shaft to decouple the front half of the cylinders, and you'd need the ancinaries on the back of the engine (or possibly in the middle?) so they don't stop when you shut down the front half. Then you have the complexity of servicing what is essentially two engines with little clearance between them - imagine changing the timing-chain on the back three cylinders.

ETA: I suppose another option would be to put the the banks beside each-other with some kind of clutched transfer box connecting them to the gearbox.

tbh I think that is pretty cool actually.
