Well, my favourite ones are "The Dreamers", and "Arizona Dream"
Both my style, the best i've ever seen:P

Quote from Simpson :

The reason is simple. Stock cars are made for low/middle range rev torque

Car is comming from factory with turbo that pulls as low as possible, but its big enough to give about 70% of boost at max rpm. If you check factory claims, most turbo cars have biggest torque value at about 2-3k rpm.
Its because factory turbo has very fast reaction time (spool up), great for normal driving, low emission of CO2, great fuel consumptions etc.
Small turbo (in road car) can create a lot preasure at low rpm, and higher you go with rpm, then more small turbine is blocking the exhaust gasses.
Higher rpm equals higher requirements for air, and turbine cant pump more, and more air infinitly(?).
If you push "power button " at low rpm (lets say 2k rpm), than turbo is starting to pump more than you need, lets say 1.4 bar, you need only 0.8 bar, so you throw rest of it (0.6 bar) to air, or to exhaust, to slow down the turbine and not have such high overboost.
When we drive thru rpm's (5k) we have still 0.8 bar, but turbine is pushing max air as it can, and at bigger rpms turbo cant pump such big preasure, so preasure drops, and engine is not creating much torque

If you take bigger turbo than everything will be same, but moved later at rpms. So you would have max boost later, and boost drop would be later.
Its all depend from turbo. Stock cars have normal turbos, normal bearing, but when you tune your engine you can buy bigger turbo with ball-bearing. It will pump more at low, and wont block gases at high rpms, but you wont make with this turbo big distances (100k miles )

Nice in theory, but irl not always true. Nearly all turbo-charged roadcars can be tuned to much higher performance levels. This can only be done because turbo' s are often oversized and overengineerd to make sure it is still reliable in case of poor maintenance by the owner.(although it will still last less long, but the engine/turbo will usually still be able to do over 200.000km). On road cars, it is really the ecu which determines how high a turbo must spool up at any given rpm and throttle position.

My current car it is in the extreme, because volvo used software to create a low power 2.5 diesel(2.4d) and a very nice higer powered 2.5 diesel(d5) with exaclty the same parts on the car to serve different market demands. So i tuned mine to the higher(d5) power version. but if the gearbox would be a lot stronger i could achieve the following by just software; : 130HP->198HP @4000rpm and 280HP -> 435NM@2200rpm. This is only possible because the fitted turbo is much better and overengineerd then needed to make it very reliable and durable. However, since the gearbox will fail within a year with so much power, i can' t make use of the extra headroom However i did run the the car with this tuning for a week, it was ehm very fast. No youtube movie of volvo d5(tuned or not) could beat my car in terms of accelaration. Since i don' t like buying gearboxes every two years, i had the ecu programmed back to D5 values.

So the powerdrop at higher rpm's with turbo-charged road cars is usually not caused by a turbo being too small but for other reasons. Generally, on road cars turbo' s are much better/bigger/stronger then needed and kept a bit down in terms of boost by the ecu. To get 20-30% extra power and torgue you usually don't need to fit a new turbo. The extra boost, if ecu is reprogrammed properly(very important, bad programming will break everything real fast) will not hurt drivability in anyway. The real challenge is, to get to know if all parts in the drive line are able to cope with the extra torgue of the engine.

may or may not be a bug, although this never happened in z or z10 so it could be. driving on AU1 layout.

Strange pole like object sticking out of my car, not visible in any other view apart from incar and not there in the replay i saved.

I was not able to reproduce it, it just happened randomly and was there for the whole race but went away once the race finished and restarted.

Radeon hd2600 pro (AGP) running omega 3.8.442 drivers if that helps.

Most likely overheating. My graphics cars also has such issue's, but never in lfs because lfs does not stress the gpu enough to overheat.
If your budget allows.. upgrade your system If your cpu is still somewhat up-to-date, there are agp ati 4650 cards available which might be perfect for your system(check first power requirements before buying)

Yes, there is. You might find this useful: http://www.lfsforum.net/showthread.php?t=11856
Unfortunantely, you, as a demo user, cant upload them to LFS World, so it can't be seen by other people.
but you could ask a friend to do it for you :P

Quote from ajp71 :

Chassis flex is noticeable in all cars, production racing cars go to large lengths to increase stiffness as much as possible by using the rollcage to form an effective spaceframe welded directly to strut and diff mounting points, a complex rollcage comes with a large weight penalty which is still worth paying to gain stiffness.

Its a bit the other way around, a roll cage is mandatory in nearly any race-series. So if installed, its not more then logical to make use of it to improve the stiffness. Since cars prepped for racing are usually very stiff because of the rollcage, its makes maybe not very important to implement?

Also i doubt formula cars and gtr's have any noticable bodyflex, the monocoque chassis are incredibly strong.

Quote from cmanns :

Hey Devs, the wine problem just

I really dislike windows-os, but i will run into a lot more problems in trying to run windows apps(games lol) on other operating systems then just running an recent microsoft OS. Also because it is nearly always unsupported and for small software developers really a waste of time to support platforms for which the software was not written or intented.

My opinion is, if you run an windows application on linux you are on your own if there are problems.

(this post is not intented to critisi linux, jus annoyed people start complaining: Application build for Operating system X is difficult to get it running on Operating system Y. Well duh!)

Hm...Doesn't this thread smell bad?
Don't we have enough bad taste arround us?
Just asking

Quote from SmegFirk :

I don't think you can make the limiter work on rpm because you alter the gear ratios and you could be going quicker than 50/80 before it kicks in. It is supposed to be used to stop you going over a certain speed when you are rolling, especially coming into the pits.

If you are using it to wheelspin out of the pits with a safety net, you deserve to get burnt.

No problems so far for me with this patch

Hej Live for speed runs on Ghz computers, the math needed to get the correct rpm with a certain gear ratio will be on average calculated in less than 0.0001 seconds. Its just needs to be correctly coded in lfs.

Quote from ADOLF1612 :

It isnt overheating: cheked the Temperature: 45º Celcius In Graphics card and 51º in CPU, and it happened me once with my previous Graphic card (a Nvidia GeForce 6200 New out of the box, i sold it coz that).

And i just got annother crash, again i cant get a crash report, just the adress on the windows blue screen, btw it was different, here it is:

*** STOP: 0x0000000A (0x9D074060, 0x00000002, 0x00000000, 0x80521798)

Tryed Normal Patch Z and it didnt happened, and something i Missed: It only Happens in MultyPlayer Mode During a race, spectating is annother case.

EDIT: Something even more weird: i´m using Z10 since it showed up and I didn´t got any problems so far, since a month ago I think, so it isnt an only Z13 problem...

I did a short search on internet, most likely driver or hardware problem. Did you try other games which are serious hard on hardware with vsync disabled?
Search on google and own experience of overcloking all points towards hardware-problems or serious drivers problems. You'll need to thoroughly check your own system and figure out whats wrong with it.

Quote from rockclan :

I do have a bug to report.
Sometimes with the FO8 in limiter accelerating much, you get a drive trough penalty, for speeding.

When it is in speedlimiter.

I had this in a big test race and was really furious!

Please fix this bug.

Same happend with BF1 accelerating in limiter without TC.

If i'm correct, real speedlimiters often work on rpm, not the rate at how fast the tyres are working. So in first gear with speedlimiter on, you should not be able to do more then xxxx rpm and for BF1 1xxxx RPM depending on gear-ratio's. It should not be too hard to implement calculations in lfs to limit on rpm.

However, as it is now, i don' t experience it as a bug, since the pitlimiter is an aid for an driver, not an tool designed to save you from speeding when doing an burn-out in pitlane. As an aid, its works very well, although it limits too soon. A real pitlanelimiter is very accurate and will limit at 79-79,5km/h not 77 or 78 as it is in lfs right now.
So it would be nice if the pitlane limiter in lfs would be improved on accuracy, but i don't think it is the most important thing on the list


edit: I' m very happy to see an update again, confirming the lfs-crew is working very hard to get the simulation improved as soon as possible.

send us links!!

Here: http://www.flickr.com/groups/3d_stereo_pictures/pool/
You find lots of interesting photos and landscapes in 3d

Barrel-roll was the perfect stunt:P
U have lots of talent, u surprised the moments nicely and the music fits like a glove.

I'd be happy to see a race/hotlap, etc like that.
It works just fine since i got some experience in this kind of stuff (used to watch stereophotos for hours on flickr, and also made my own:P)
Good Luck!

As most of you said, a racer/cruiser must be decided from the beginning, but an idea would be to place this in F12 screen and turn on/off at each pitstop, as well as tyre change, ammount of fuel added, etc. (because IRL in most cars u can't switch ABS on/off while running, u must stop in order to remove the fuse).

Well, i don't know what to say. It is not 100% necesarry, as you said.
But, IMO it would be nice to have the feeling of drum braking, and also the idea of brakes damage would work just fine.
+1

That progress seems nice. I tested it as well as in online as in offline, but i think i have a problem: when i tried to join a specific host, LFS crashed 2 times (at the same host). Iff i'll try again, i'm pretty sure this thing will repeat.
This didn't happen in Z10.
I'll get Z10 exe again, i hope that'll work

And BTW that host was z3 if it has any importance.

Also before releasing clutch rev it to max torque (don't remember what was it on FZR). That helps

Quote from ANAMENOONEHAD :

they should take abs out it so silly seeing people apply full pressure then just totally lift off and the car is stable makes it soo noob freindly. Ive raced with people on bl1 xrg that would do high 133's now they are doing near 132's because of abs. takes the driving out of driving IMO i guess im just old school where drivers input the controls not electronic systems.

I agree, i tested a few laps with a car with abs. I set the brakeforce very high. And for each corner just hit the brakes hard and the abs will do the work for you.

I was just wondering about exactly this topic is avout while trying to find a good setup for a race.

I think we all agree the front-downforce on gtr's is too adjustable right now. Maybe an moderator can move this topic to the improvements-section? The improvement would be: Less adjustable front wing on gtr' s.

Those canards at the front are currently not very effective/realistic, i think they should be free of the rest of the body work. The backside of those canards are connected and blocked by the rest of the bodywork which would make them very ineffective. As it is right now, they should stick out of the sides to look realistic. But not really an issue as most of us care more about realistic handling then looks.

On the other hand, the rear wing and, also the front wings on formula cars, should have finer adjustments possible , but there is already an topic about that somewhere.

Amazing quality and nice slowmo.

It shows some of lfs's small bugs but for a two hour work it's just great

Quote from dougie-lampkin :

Holy bump batman!

Wheel damage isn't that common apart from scratches, dents and marks. I remember the picture of the Porsche test driver that crashed on that Autobahn, had a few spokes ripped off a wheel, and he went into a median barrier doing well over 150. Suspension and drivetrain damage would stop you long before wheel damage I think

Agree 100%
If someone manages to damage the rim, changes are at least 80% the suspension will also be seriously damaged. This is often seen in F1 races, rim damage is very rare, but tearing off the entire wheel from the car in a collision or crash is rather common. And those F1 rims are very very light weight.

So rim damage is rather pointless to implement i think.

Quote from wheel4hummer :

It is a very interesting idea to use a supercharger to spool up a turbo. Maybe such a system should be implemented in the FXR and XRR? The supercharger would compress the air to about 4psi, and then the air would go into the turbocharger, which would compress it to 24psi. When you press on the gas, the supercharger would be forcing the turbo to spin! There would definitely need to be a bypass valve between the supercharger and turbocharger, because a supercharger reduces the engine braking since it is constantly compressing air.

huh?
Superchargers blowing air directly into a supercharger is pointless, its an much better idea to blow this extra air into the engine which can use it to generate extra power and lots of extra air-volume(exhaust..) to spool the turbocharger even better up and at the same time generating nice low-end torgue for the driver.

There are irl cars with have a small supercharger and a turbocharger. The supercharger is used when the engine is running at low revs. As soon as the rev get over a certain point the turbocharger takes over smoothly. At certain point, the small supercharger will be too small to be of any use. At that point the ecu will bypass the supercharger(electronicaly controlled valves in airintake) and all the work for blowing extra air into the engine is done from that point by the turbocharger.

VW golf 1.4 tfsi (GT) for example is using such system and it works very well. Performance is comparable to a 2.5 liter v6. Fuel usage comparable to an modern 1.8 4 cylinder at cruising speed. Since power essentially comes from burning fuel.. At full throttle the fuel usage will be nearly as high as the fuel usage of a 2.5 v6 at full throttle.

wen i schicocko cum ?

i borded of fxr;ez

I am also borded of fxrz plz now schicocko now guy.

Most likely the MB dying (worn out caps etc.) or broken RAM.
