Scawen, I had some texture glitches..


though it went back to normal after pitting

Could also be the pit out glitch fix, if that was an on board shot of another driver

That is a very simple and yet powerful suggestion!

Sorry for the unfounded comment

perhaps I should have used better words like "More processing is required to achieve an acceptable level of realism".

However I am sure you knew what I meant. we aren't gonna be seeing LFS on iPhones/iPods anytime soon!

I don't think it is quite that easy!

X-plane was already available for mac Os so it was a relatively simple port and optimize.

LFS would not be that easy, besides calculating accurate On-Road Vehicle Dynamics takes alot more calculations than accurate flight modeling!

As for the OutGauge app, definately!

I'd already be working on one, if I had a mac!!!

V8 Supercars run a spool, inside a ford 9" housing.
So they are a fully locked diff.

So yes locked diffs are used in a competitive racing series.

However, as V8's also run a live rear axle, I'm pretty sure they run them like a kart and unload the inside rear wheel.
You will notice rear roll center is one of the most critical adjustments they make.

But yeah, they do it because its the rules, not because of benifits

Plus the legends race series in the states, Aussie Racing Cars, IROC cars in the states and also Indy Cars on Ovals run spools.

this would be how I would do it

Check this out aswell:

"AIR PRESSURE
The amount of air in the tyres. Changing air pressure in the tyres is used as setup tool. Higher air pressure will create temperature in the tyres faster than a lower tyre pressure."

Grip is the result of friction between the tyre and road.

The two different principles that effect friction with regards to tyres are adhesion and deformation.

Adhesion is the chemichal bond between the tyre compound and the road surface.

Deformation is how the tyre compound changes shape to follow irregularities in the surface. The more the tyre deforms around the surface the greater the surface area or contact patch. This means that there is a greater contact patch for adhesion to occur.

Quote from Zachary Zoomy :hehe. this didn't take long did it? I wanted to make something like that first though :P

nope

for the record i'm not actualy a rice boy, and i also view chemichal forced induction as cheating!

Just when i saw the fire extinguisher I couldn't resist being the first

It's purely for scripting, there is a script file for each car, and there is also a script file for every car that has a sequential gearbox. So if you wan't to change parameters on every car that has a sequential gearbox you would put the desired script in the sequential.lfs file, rather then putting the script in each of the cars files. I guess that he must have forgot to update previous versions to include the FXR.lfs and XRR.lfs to include the sequential.lfs.
SO it's realy just a tiny bug fix.

Someone has already written a g-meter overlay, i think they called it DriftMeter because it also had a slip angle meter, check that out.
No point in getting it directly implemented in lfs realy, doesn't add much value.

definately no need for 5.1, however 4 or 4.1 could possible, maybe, be ok. One benifit of using 4.1 over 4 is you could use the 5th channel for a shaker, instead of a sub. And that way viabrations the car is experincing can be sent through the 5th channel. However that would be a very big task for not much increased realism in return. As has been said earlier though, while it may be possible to to give lfs 4 channel sound, how much of a difference will it make? If you can hear a car, however you can't see a car, then it's not in front of you. Yep thats right it's behind you
I know it may be a hard concept to understand but trust me it's true

If this was a commercial game, then yes i could see the advantage of coding 5.1, because then you can say that on the box and people that didn't have a clue would think that it's great!

Seriously, In Motorsport and Road car Aerodynamics the term 'Negative Lift' is used aswell!
Ever heard of a L/D ratio?
It's the Lift to Drag ratio wich in F1 is a very important ratio, something that teams are always trying to optimize.
Downforce is the commonly used term, Negative Lift is the more technicaly correct way of exactly the same concept. Because with lift you can specify a direction, positive (up) or negative (down). And as Bob said most road cars do generate lift, and also certain aspects of a f1 car will generate lift (one example is the Helmet of the driver). It doesn't matter which term you use personaly, it's probably better to use downforce, as it is a more common term. I only raised the point beacuse someone commented about me using the word 'Lift'

Still I like this thread, we need more aero threads on lfsforum

Quote from Stang70Fastback :Just remember, we're talking about an automotive wing, not an aircraft wing, so pretty much everywhere where you said "lift" you meant "downforce."

True, however also remember that aerodynamicists refer to downforce as Negative Lift

There is a whole lot of confusion here!

Firstly there is a very good understanding of how wings work, there is just heaps of overly simplified versions out there that just muddy the water.
However, it's true that when you start adding things like turbulent flow, things get trickier to culculate.
As for some in this thread thinking they nearly as much as engineers that specialise in this field peharps not, if you do abit of reseach you will find some very helpful information. The problem is there is also a lot of garbage.

For example, people often say newtons laws do not apply. Thats wrong, because air has mass so they do apply, if you deflect air in a certain direction, there will be a force upon the object in the opposite direction.

People say that it a fluid has to take the same amount of time to travel over an object as it does to travel under. This is absolutely not true.

And also it is important to understand that it is not just the shape of the wing that has an impact on the pressure difference and therefore lift. Take an airplane for example when flying inverted why do they not fall out of the sky? Because the angle of atack plays a critical role in the amount of lift, not nesicarily the shape.

And also someone refered to negative pressure, but were told they were wrong, however they were not wrong they were refering to negative pressure relative to atmospheric pressure.

Best thing to do is read up!

*edit* I found this

We have seen that several physical principles are involved in producing lift. Each of the following statements is correct as far as it goes:

1)The wing produces lift “because” it is flying at an angle of attack.
2)The wing produces lift “because” of circulation.
3)The wing produces lift “because” of Bernoulli’s principle.
4)The wing produces lift “because” of Newton’s law of action and reaction.

We now examine the relationship between these physical principles. Do we get a little bit of lift because of Bernoulli, and a little bit more because of Newton? No, the laws of physics are not cumulative in this way.

There is only one lift-producing process. Each of the explanations itemized above concentrates on a different aspect of this one process. The wing produces circulation in proportion to its angle of attack (and its airspeed). This circulation means the air above the wing is moving faster. This in turn produces low pressure in accordance with Bernoulli’s principle. The low pressure pulls up on the wing and pulls down on the air in accordance with all of Newton’s laws.

in wpf to dock and anchor
you use Vertical Alignment and Horizontal Alignment along with Margin

I think the idea behind this was to make it familar for non-programers to design user-interfaces (hence xaml) and those members are fairly obvous to understand and also very similar to HTML

*edit* and also the designer in VS2008 is very usefull

Thats the main point of his post, not realy that confusing after all

As for this being cheating, if the lap stands with the current HLVC then not really cheating, although still wouldn't be very statisfying to get a WR in that manner.
