Quote from hinirags :

Maybe because of a locked differential, or high locking.

That is the reason.

To reduce that phenomenon, harden up in small steps the rear antiroll bar, till you can control the corner exit oversteer.

Allso you can try use the gas in a smother way and reduce the braking at the same smooth way.

If you want just a realistic setup to play with, get rid of the locked diff and use a clutch pack with less than 50% locking power. Also you will have to re adjust at least front and rear antiroll bars cause in order to make the locked diff usable, setup makers use much harder antiroll bar at the front and this is not what you want when you have a normal diff

The only reason to have a turbocharger and a supercharger at the same engine is to reduce turbo lag. In that way you can fit a gigantic turbo which only operates optimally at high rpm (that explains the high power)… and then you use the other supercharger to operate at lower revs so you have a wide and usable power band.
There is not such thing… turbo plus turbo or charger plus charger for ultimate boost… this is just for the show.

Quote from Crazy Harry :

What is strange with a race engine that wants to run round in low rpms? Did you ever tried justa simple 300°+ camshaft in your cars?

I can’t understand how you defend your low revving opinion, referring to a 300ο camshaft… these are absolutely irrelevant things. That kind of camshaft does not work at low revs at all…

Honestly I haven’t seen a car that has more than 4 turns lock to lock… (1440degrees)
So I think the limit of 2.5 turns or 900degrees are ok for sim racing (not bus driving)… there is nothing to gain with just more turns.

A 2.9 turn wheel and feel sporty and quick at family or hatchback cars… eg ford focus has something like that…
You will see 3.5 rotations from lock to lock at most of the cars that have nothing to do with the “sporty feeling”.
3 rotations are 1080degrees btw…
Sporty cars have around 2.5 rotations lock to lock (eg S2000) and expensive sport cars have around 2.

These camper values are not really strange for so narrow and high profile tires with that low pressures.
The low tire pressures are abnormal… And as long the LFS’s engine does not simulate tire puncture due to extreme deflection, this will remain the same.

You can do both of them.
I can’t see why we have to choose what is better for you.
Do whatever you like… the main goal is to have fun.
Racing is far more exiting than “cruising” if you have racers at a close level to compete.
It is not hard to be competitive and stable because you are young and others are older… You just have limited racing experience. Even if you where 20 you would have the same difficulties at the beginning.

Quote from Bob Smith :

That's just the weight of guilt for all those nasty things you did as a child. Be naughty some more with your left arm to balance things out.

Does that work only with the left arm?

It is easily noticeable when the front suspension is damaged (mainly the shock absorber rather than the camber or toe)… that creates the essential, for the Torque Steer phenomenon, torque imbalance between the front wheels, that ΒΒΤ has referred at his post.

I made up to 7 level in something around 2 hours trying to understand what’s about this game… it seemed to be interesting and fun for a while... but then I started to get bored and when I exited, I felt somehow sad for the time I lost :Kick_Can_ :sleep1:

Quote from tristancliffe :

I shall test it, with a valve spring.

How does the spring 'know' the 100lb is preload, and use it to absorb further load rather than being further load in the first place?

The spring doesnt know... the "preload" stops pushing the spring if you want to compress it more


Edit
I am useless at drawing especially using the mouse… but I thing that you can understand what I am trying to say.

You can prove it by testing it in your own F3000 or
Just find a spring with constant spring rate and play with it (maybe you can find it in a cheap pen.)

You can also analyze the forces theoretically but I feel too lazy to do it right now. (I will try later)

Quote from tristancliffe :

Evilgeek - In your example you are pressing the spring away from the spring platform, and in that scenario yes the new load has to take up the old preload. But in this real life racing situation we are compressing the damper unit - the spring platform is always applying it's preload function. Therefore the compress the spring in your example further by moving on end of the clamp, you can apply any load. 1 gram or 100kg will move the spring.

As people have said above, if you apply a load of 100 it compresses x. If you apply 200 it compresses 2x. There is no way in God's World of Physics that applying 100 compresses it x and the next 100 doesn't compress it at all. There is also no way the second load compresses it 0.8x (i.e. the spring get's stiffer), assuming we are not at the point of going coil bound.

I think that’s where you have being confused.
The physics you are referring are correct but
Preload isn’t a force which is being added to the spring constantly as weight does.
It is an initial force which is caused by compressing the spring to a given initial length. When you compress the spring furthermore the preload has no effect at all.
Of course it does not increase the spring rate but it does increase the minimum force you have to apply in order to start compressing it.

I tried to make a kart set, long time ago but it is impossible cause fsae is completely different from a kart… there is no suspension movement whatsoever in a kart.. Only chassis flex.
As I see my kart set philosophy is close hotmail’s sets with the only difference I did not try to eliminate suspension movement. I chose the higher equal spring rates for both front and rear suspension leaving it almost undraped and I used the anti roll bars to balance it like a kart but it is just not working lol… it feels like a cart with terrible or broken chassis without any torsion bars.

@ anttt69. Placebo

Thanks

Good one keep it up!

Nice slo mo vid there.
It would be good to upload it somewhere in higher resolution

Thanks for the comments.
Yes felplacerad, there is some OLFSL footage

No effects, just race action.
To be honest, I hadn’t anything specific in my mind to create so there isn’t any plot at all… just action shots put together following the music but not always the bit.
I hope it is entertaining.

Beautiful artistic scenes Nicely directed and edited.
My imagination has abandoned me so I got Jealous (in a good manner) seeing your camera work.

Great one Don :hyper:

Yes earth’s climate characteristics change over time… In a period of “a number” hundreds of thousand years, global temperature rises and falls from +XX oC το -ΧΧοC… that’s normal…
What is not normal… is the rate of that climate change in the past 100years…
And the most worrying is that the rate of the climate changes is increasing...
If that was normal, there would be ice age every 1XXX years.

Quote from Kronvall :

But the download version is better - try it.

I have already downloaded it and gone straight in my favorites
But I think it still looks a bit to dark for my taste but this is not a big deal, it is easily adjustable

It is always nice to see a crowded track.
Good one Kronvall

It looks a bit too dark on youtube maybe you could check it?

Nice drifting but you need to put more effort to camera directing and video editing to make it look more attractive… And maybe a combination of slow motion-normal speed scenes... I do not know you will figure it out

I just don’t like any video with fast forward action… it doesn’t look true even when it’s from real footage… from a 3d environment looks even worst.
Just speeding up the video doesn’t increase the sensation of speed… its not that easy to fool the viewers eyes.
It may be well made with clear camerawork and editing but that wrong fast forward feel, destroys it for me.
