Hi
Just a few quick runs

Willow Grove

On spawn in you get put into middle of paddock , if you go forward you fall through the world and land in pit area.

The inside walls on the straight seems to have a lower track level than the rest and if you ride the wall eventually you will get stuck with the left hand side of the car sinking lower than the track.
The out side walls on the straights seem to an extra bit inside that the car hits , it doesn't really affect the car apart from a louder noise and a bit of a jolt

The Car

Disclaimer !!!  I have no knowledge of these cars , but to me it seems to accelerate way to quickly 0-100 km in under 3 secs, (using bad counting method).
The engine noise doesn't kick in when is second gear until you reach 4k revs , to me that should be the idle noise up to that point there is a little whine/whistle almost . Its the same as in !st gear but you get to 4k revs so quickly its not that noticeable. but i spent most of my time in around 3k to 5k in second while lapping.

I found it hard to go in a straight line on the straights while accelerating using say about 60% throttle it kicked me out to the right quite often. That could be my lack of skill in the car.

Some graphical thingys on the walls, hard to describe almost like triangle shaped shadows along the seems of the walls.

Light posts no collision you prolly know that though.


For me i think it needs more lower speed grip and more longitude grip, that is just from a game play point of view.

I'll play with it more next week and see if i can find other things worth commenting on.

Thanks for feedback.

Must be using 'Hotlap'? I'll add in and check the needed spawn points.

I noticed the inside walls, I think that under the wall there is no track so as AC lets you pierce the wall we a probably falling through, can fix that too.
Outside walls are at the track edge, so graphically you can pass through the wall a little.

The sounds and handling come good as you up your speed.
As you get used to the rhythm of each track you should find yourself going, if not straight then at least going in the right direction.

Use only one gear, be that first or second depends on the track and available ratios. The wheels are spinning like crazy, they make nominal max grip at 42% slip!, so gear it to be over redline at the end of the straight.

Even jumping from one track to the other I think WTF have I stuffed up here. But giving it a few laps until the rhythm kicks in and it's all good again.

I don't think AC will ever allow me to build 'real' physics, but I hope to get close and have a car that you can tune and with practice get faster with so that your effort is rewarded.

That is good feedback I reckon

[Jarmel]

I didn't think to even look at the gearing or setup.

yeah i did notice once i got going i got into a bit of a rythym and changing the gearing will help even more as well make the engine sound a non issue. They do sound great when revved out.

Yes i was using Hotlap start

[Jarmel]

   I did fix the stability at high speed ,  i took it for a run around 66 monza , just needs a lot of toe out as shown in this pic


Also took it for another spin around willow changed the gearing , had 2nd as low as it would go and it would almost hit max revs at end of straight but thru the corner the revs were so low that engine noise was basically gone.

The first lap attempt at monza once i got to about 140ish k's the car would not drive straight at all . I know its not a road car but i think this plays into its handling on the dirt. Also the wierd thing was it seemed to only kick me out to the right not the left on the dirt. This was using default setup apart from diff ratio. Also the diff ratio could overlap a little more, lowest top speed in 2nd was 203km from memory but highest top speed in 1st was 159km feel the gap should be closer.  Also not sure the car should be able to go 250km + on a road circuit (once toe out was in play)

Its showing alot of promise .

[GzeroD]

Yeah, Dirt specific I'm afraid. I have anther version for the Paved courses. Check my 'Indy '52' Compilation.

Two Ticks, I'll post a replay at Williams Grove.

Here 'tis

[GzeroD]

[WRONG]Quick rethink on the gearing.
In a given gear max acceleration is at max torque.
Max torque is at 4000 RPM, and there is a healthy hump from 2000 to 5000 RPM so choosing a ratio that stays between those numbers should be quicker.
I'll probably need to find a new engine sound for such a low operating range.[/WRONG]

Fuck I'm a Moron, next thing you know I'll start believing in Jesus.(We all know Xenu is the one true Lord)

New version of the car, only one gear now and increased drag.
Same link, see above.

[Jarmel]

I watched your replay and it is like your driving a different car . Looking at your inputs your using full acceleration as your almost half way out of the turn  , I have to be gentle on throttle and creep up to full acceleration I usually get there by 3/4 of the way down the straight.  Thinking this maybe a difference in steering wheel settings. Its better if I use toe out to the max on all wheels.
Can you post your setup your using if its different from the default. I'm using a g29 wheel fyi. maybe i need to look into my wheel settings

Oh that pic at Monza was after a crash, that's how the toe out was so extreme , but the point of it was that for a car this age it is way too powerful, doubt many cars from this era would be hitting 280k on the straights at monza with only 2 gears.

[Jarmel]

Little replay showing how it kicks out for me

[GzeroD]

That's the rhythm part. You will pretty much still take the straights is an S shape but as you get better you stretch out that S curve until it is practically straight.

Do you have CM>setting>ASSETTO CORSA>CONTROLS>Hardware lock (experimental)   Ticked/Enabled?

Although now I look at the cars the Vintage Offy has 720 degrees of lock and the Sprintcar has 540, both of which is not unusual except that the steering ratios used means you have 72 and 180* degrees of turn in the front wheels respectively.

*This makes no fucking sense, the calculated value for that car is 180 but ingame it's only 80 so either myself or Kunos have broken the laws of physics. (at least virtual physics)
