Thanks for clearing up that for me. :sunny: I recall someone mentioned there were 3, but now that I think of it - I remember a discussion about SH4, which had 3 watches and how U-Boat add-on couldn't simulate two watches properly. :)

Regarding 'overcharging' diesel engines.

Yes, I think that is outlandish.
Aircraft engines where built with mechanisms to run them at speeds that
reduce the service time. They where designed that way. It wasn't some
modification or tweak. It was done in one of three ways; by removing
the manifold pressure limitations (i.e Spitfire V), by injecting methanol
and then water to prevent knock (i.e. P47) or by increasing the
supercharger speed and injecting cold fuel after the supercharger to
prevent knock (i.e. FW190).

Uboat engines had no mechanism to run them at speeds that would
reduce the service time. It is inconceivable how this could be changed in
the field or even at port.
You can't add anything to the motor as you don't have an injection
system and without a protective layer methanol would very quickly
corrode the engine (there was hardly enough chromium in Germany to
proof aeroplane engines, let alone uboats). You can't run the
supercharger any faster or your engine will just knock and there is no
point opening the throttle beyond what the engine can suck in.

Better fuel might help (the uboats got crappy fuel), but your hardly going
to sit there with a bucket of premium ready, even if you did get your
hands on some. How would you put it in anyway?

If it was possible and it was done, uboat.net would know about it.
It wasn't.

The concept of overcharging engines in general isn't wild fantasy, but
the idea that uboat engines could be, or where, overcharged is fantasy.

As long as they didn't get rid of Willi Pelz, I'm ok.

one aircraft i routinely fly is "overcharged" without the use any of those methods. :yeah:

I cannot say for sure what the Devs have in mind... but i'm willing to assume that they have a plan on this matter that does not involve "magic" in any way shape or form

I thought I remembered reading somewhere that the Obersteuermann commanded the third bridge watch.

Can't find it now, though, so it's just a memory.

Wanna put some money on that?
;)

fromhell 02-03-10 03:56 PM

i remember in a tv program, a uboat captain, forget who, saying that while on surface, they used the electric engines as well as the deisel, to escape a convoy escort.
enyone heard of that?

sure.

$10?

I say there are at least a couple of things that can be done at sea by a knowledgeable mechanic to temporarily improve the performance of a diesel engine.

i dont care what machine, what computer, what device you are working with - there is always some way to boost the performance beyond "factory limitation" which is the exact language the ubi web site used.

I'm confident that this will only be effective for a short period of time... im also quite confident that it will not involve "magic" and that it will ultimately result in a gain of only one or two extra knots.

you wont see your Type VIIA cutting wake at 35 knots.:doh:

OK, a $10 donation to subsim is fine by me.

If ubisoft explain what it is that makes the engines go faster and how it
was possible during the war (and thus no magic is required); you win.

If ubisoft don't explain what makes the engines go faster and/or it wasn't
possible during the war (and so it must be magic); I win.

If the feature isn't in SHV; it's a draw with no transaction.

/shakes.

:har:

Letum i like you but im no fool.

the entirety of our bet relies on Ubi explaining something? :haha: oh.... oh... oh... My sides!!! I'm crying!!! LOL

how about this... if anyone can produce reasonable evidence that increasing the performance beyond factory default - even if by a small margin, of a desiel engine at sea is possible.

and in SH5, once released, the mechanic doesnt just say "Jawol herr kaleun" and it suddenly happens.

then we have a deal

i saw a guy do it on tv by pouring whiskey in the oil

what a waste of good whisky :nope:

Sanuck 02-03-10 04:18 PM

Thanks goldenrivet
My first post and at least some positve thoughts
i agree that, well i hope this was a rushed translation job
i for one am looking forward to the new game, although i have great sympathy for those with internet issues, as i might at sometime and it will
make me mad.
Lets see what web updates follow :salute:

fromhell 02-03-10 04:19 PM

yeah man:haha:

"For a short burst of high speed on surface, if the state of the batteries permitted, speed could be increased about half a knot by running the electric motors and Diesels simultaneously. "

Well, hopefully the engineer would have done all the work whilst in the pen, where he could have the engine apart. There's little you can do whilst you need the engine to be available/running, other than inject more diesel. Diesels have a direct relation between the amount of diesel injected and the power produced, right up until the smoke goes completely black and starts ejecting unburnt fuel. That comes at a cost of fuel efficiency of course and if you run your engine at too high an RPM it can be damaged with joints parting / bearings overheating or melting etcetera.

In port, he could balance the crankshaft, polish the air intakes, check the injection timing, perhaps change the oil filter for a less restrictive one, perhaps if he wanted to change the compression ratio by capping the pistons. It depends what he had available to him. Things will come out of the factory to within a certain tolerance and can be improved.

all very real possibilities.

we cannot know at this point if the mechanic will be "animated" performing such things. - im doubtful of it

but it can be assumed that these are reasonable things he could do to boost Diesel performance.

in addition to my previous post about daisy chaining the diesels and electric motors.

That wording leaves no time limit.
You could just say that someone is about to provide evidence until the
cows come home.

I don't quite see what you don't like about my wording, but this removes
the need for Ubisoft to explain anything:

If anyone can explain the mechanism used in the war to increase engine
power in the uboat's engine, as simulated in SHV, within a month of
release; there is no magic and you win.

If no one can explain the mechanism used in the war to increase engine
power in the uboat's engine, as simulated in SHV, within a month of
release; it must be magic and I win.

If the feature isn't in SHV; it's a draw with no transaction.

In the event that there is disagreement over whether the mechanism
behind the effect in SHV is explained and possible, it goes to public
vote.

Agreed?

Very well, if the battery power decreases during the diesel engine overdrive then it is explained.

GoldenRivet 02-03-10 04:29 PM

deal... its only $10 afte rall.

but have you read the previous 3 posts?

there are several things a skilled mechanic can do to boost engine performance temporarily even if by a small margin.

Schroeder 02-03-10 04:31 PM

@Sailor Steve

I belief there was only the port and starboard watch. Nothing else. But I'm not really an expert.
