Oh could they? Tell me more about how to reliably turbocharge a 5.0 V10 with a 12:1 compression ratio and keep a sane service schedule, and how it'll make more power than a 4.4 V8 with a 9.3:1 compression ratio.
I'm sure the intake/exhaust valve overlap profile of the S85 is ideal for turbocharging though compared to that stupid S63, and the colossal amount of heat it produces is a piffling detail.
I never said it'd be as simple as just hooking up a turbo to the old engine, some modifications would have to be made. My point is, all other things being equal, a 5.0 TT is probably going to produce more power than a 4.4 TT.
And where is BMW getting the low-compression, overbuilt five liter V10 to turbocharge?
Again, not seeing where your bias against turbos (except perhaps for the lack of sound) has any grounding in reality...
The V10 was a high-strung, high-compression motor that required insane rpm to hit those 500 horses. It also required very, very special engine oil and needed high octane gasoline to hit its power numbers, otherwise power is dialled back and sometimes knock could occur.
The break-in requirements of the V10 are also fairly restrictive and include a 5,500 rpm electronic limiter that kills power before things get really interesting. (accounts are contradictory... it's basically the P400 mode, but in some markets. like ours, it's locked into that until the first service) That's pretty annoying.
Ergo: You're defending an over-engineered, whiz-bang high-strung technological marvel of an engine over something using good old-fashioned snails that can run on regular gasoline... simply because you don't like escargot.
@homeforsummer : I don't mind sound symposers. That's actually the sound of the engine itself. It's like peeling away some of the sound insulation so you can hear more of what's going on. The M5 plays the engine through the speakers... which is two parts cool and eight parts fairly ridiculous... maybe I'm sounding a bit brown and geeky saying it, but that's just plain conceit.
If I had one, though, I'd probably try to find some way for it to play Mustang music...
blah blah blah
But you're right, I do hate turbos. I'd rather have a supercharger with its spine-tingling shriek and amazing ability to not need variable geometry whateveritis to not lag, or go NA, than have some stupid exhaust gas recycler that makes a stupid little whistling noise when you can hear it at all. And now, turbos have become a major defining characteristic of a Greenpeace-approved metrosexualmobile with an engine the size of Justin Bieber's talent - and to me, that stigma carries over even to decent-sized engines such as this one. For me, the Scale of Engine Manliness goes something like this: supercharger>natural aspiration>aftermarket turbocharger>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>factory turbocharger.

The Scale of Engine Manliness
I didn't know rednecks were in the market for M5s?Also, just NO on the symposer. Symposer = removed, glasspack = installed, problem = solved.
This is a turbocharged, 1.5 liter Formula One car.
This is the most powerful engine ever to go into an open-wheel racer.
A lot of things. So many things that the engine is no longer economically viable - it'd be a horror story. It already is one, but it's reliable enough at 500 air-breathing ponies that it gets a warranty. Making it hotter is not wise.I never said it'd be as simple as just hooking up a turbo to the old engine, some modifications would have to be made.
And mine is that they are not equal. The high compression 5.0 V10 does not take well to turbocharging, even if you could find somewhere for the turbos to go. The low compression 4.4 V8 does and thus produces more power, reliably - moreso even than the 4.9 V8 of two generations ago.My point is, all other things being equal, a 5.0 TT is probably going to produce more power than a 4.4 TT.
Actually as shown in the S65 (very similar) currently you CAN run boost and there is a TT system being developed BUT it's pretty low boost (~6PSI) and for any high boost applications you need a low compression built engine. BMW could have done that with the S85/65 but already having a turbo 4.4 in the 50i models being newer and less prone to failure than older engines plus with more fuel economy made the development of the M5 4.4 much easier.A lot of things.

Well that puts a different spin on things. I was under the impression that that kind of finnickiness just plain didn't exist in road cars anymore.
