Central port injection and U engines,H engine VR5 engines?

VR engines are a totally different story, if they are ever put into the game, then they would appear with W engines, because Ws are basicly made on the same tech

Although the W-Engines that VAG makes are more Double-V(R)s... and noone else makes W-Engines. There was a swede, Thomas Johansson, who made a real 3L W9 engine for his master thesis. But thats about it.

There was a W-3 engine a couple of years ago, based on H-D. Think the name of the company was Feuling. Only for custom frame bikes.

Might look good on a Morgan ThreeWeeler.

Small note, none of the H engines made so far have been Boxers, they have all been 180 degree flat engines. Each pair of cylinders sharing a crank pin.

And the BRM H engine was a 3 liter 16 cyl engine, not 40l. They even made a 64 valve version that never raced.

im not that informed on exotic/rare/proto/etc. engines, so i'll just agree to whatever you said

AFAIK VAG W is 2 VR blocks together, correct?

I would not be surprised if one of the cylinderheads of the AUDI/Bentley W-12 is identical to the one on the VR6 engine.
Maybe slightly redesigned to cope with the extra heat in the turbocharged Bentley.

Wouldn't make sense if the heads were identical.

VAG's VR engines are basically V engines with a smaller angle so it's more of a compromise between a V and an Inline which wouldn't put much into the game, quite honestly I don't even expect to see both 90 and 60 degree V6 engines, hopefully just 60 so we don't need to balance them. The W is really just a V8 engine but each bank has 2 rows of cylinders instead of 1 but they are arranged close together making it about half the length of a V with the same number of cylinders. I think A8 gets a W12 and Veryron takes the W16. Needless to say the crankshaft looks pretty wild.

[RobtheFiend]

?????..... The VR6 engine is a 15 degree V6 engine, with a single cylinderhead.
The W12 in the A8 and in some Bentleys has 4 rows of cylinders, paired at 15 degrees, then put 72 degrees apart, with 2 cylinderheads.
Makes PERFECT sense.

I know, I was referring to this post. No way the heads on a VR6 and W engine look alike.

They sure aren't the exact same casting (for one thing the ports would need to come out different sides of each head, or you'd have one exhaust in the V and one on the outside of the V!)

But they DO appear to be very similar, here is a Bentley W12 head



And here is a VW VR6 head



They look pretty alike to me, at least in terms of overall dimensions, cylinder placement, combustion chamber design, shape of the head face etc. The only major difference I can see is that the water galleries are quite different between them.

[RobtheFiend]

The Bentley is a turbo engine, maybe that is the difference.

And I wrote that ONE of the heads could be the same.
Maybe find a picture of a AUDI A8 W12 head? Could be interesting to see.

Andrew, I imagine a W12 or a VR6 as the modelling hell!



Seems they are SOHC Heads... DOHC would be pure hell.

[xABSOLUTIONx]

is DOHC on those even possible? those heads would be massive

[Daffyflyer]

Yes! Hell indeed.

I think if you look carefully they're a weird sort of SOHC where one cam does the exhaust for BOTH rows of cylinders and the other cam does BOTH rows of intake on that side. So it has a seperate intake cam and exhaust cam like a SOHC, but it only has 1 cam for each row of cylinders... but it also has 2 cams per banks like a DOHC V12 would. I swear it'd be impossible to explain to anyone without a picture like that one!

[Der Bayer]

It totally is DOHC then

[Daffyflyer]

It totally is DOHC then

It's DOHC per bank, but there are 4 banks, and only 4 cams, yet it's still DOHC per bank.. *mind-blown*

[Killrob]

Maybe... maybe with DOHC it would be... QOHC!? (as in Quad)
