AC V8SC mods

I'll keep you guys up to date as soon as I have news from the FB Group
@Anon666 and koastr Thanks to create a new thread for that.

Holden and Nissan probably coming before Christmas

Cheers

Not sure about it. The guy told me he didnt have enough time,and he isn't used to dealing with the physics, I just changed the wheel. So I assume he is using the physics from the V8 SC. Anyway he told me that when he was going to release the pack,
that he would leave everything inside to allow people to improve the cars. Just please don't modify any logos on the car.
Cheers

@spita84 in here.

I'll give it a good run hopefully dampers feel good because that's where i'm stuck lol v8's have been using sachs shockers as far back as 2006 so would be same values for 2011 holden as well except for winterbottom's team back in 2015 iwhere they went against the grain and used a public available shock called supashock off shelves for only 3 grand ended up being better in the corners then the expensive custom made sachs and won winterbottom the championship

EDIT: checked out the falcon it's using the same base as I was (bmw gt2) so no extra goodies to take from it but there is a lot of stuff I can put into it better road feel and take away the monster grip feeling.. after I finish the 2011 holden and Ford i'll get onto it just got bit of issue with low mid speed turn in understeer and low mid speed exit oversteer so it's down to mechanical grip somewhere in the dampers but I am very close to having the car finished

I got the damper data!!!!! thank god for google and this week's case of insomnia I came across a thesis written by a grad in mechanical engineering who had mathematically recreated the v8 supercars for studies on future developments for the series now it's not in english well it is but this math is mental all the numbers are there and i have base numbers to punch in will have to decipher the math for slow/fast response but have the rates lol ever wondered what half of a v8 supercar looks like in math well here it is ....its that complex i can't even paste the math but i'll type a line out for an idea

Using Newton’s second law of motion, the equations of motion of each of the four
degrees of freedom may be defined as:

‴ufz³=κτ1(z1-z³)+cτ1(z1-z³)-ks1(z³-z²+lf0)-cs1(z³-z5+lf0)

and six other lines of gibberish but that is the cars basic motion 120 pages of pure gold haha

Mate, I've got on my garage also the holden of that series of ACMI but you can found it on ADB. Not sure wich car is using the guy on my group, but at the moment, I think the guy is just doing some 3d reworking and another guy is doing the 2016 skin!
Nothing more than that

Have just got my hands onto a diagram to replicate the double wishbone suspension which has left me stumped for days without it couldn't work out how or why the run up to -10deg camber on the front turns out the GT2 wishbone suspension I was using had the top arm shorter then the rear this way camber wouldn't fluctuate as much compared to the older setup which both arms were the same length....guess which ones the v8's use...yep the older generation same length arms hints the massive camber but more interesting the lower arm on the rear is shorter then the top..PROGRESS!!!!!

Most likely alot that I have forgotten but all this work is nearing to the end just few more tweaks left
and slowly feeding off the aero and it will be ready to hand out as the final version

will try and get a video up of the graphical improvements and a lap of nord with AI

Hey Tovey great work mate, not sure how you keep up with it all.

The other night spita and I were cruising round sandown in your v8sc mod and noticed that once the cars got about 50-70 metres away from each other the car would disappear and it was only showing a hovering driver floating around also the brakes were mega sensitive to lock, like more than anything driven before.

Happy to do some testing with you if you like?

yeah that was the lod problem i was talking about after uploading that one and i trialed having the brakes that sensitive to start with but without a loadcell would make the car bit too hard so have fixed that in this build as well

The new version is night and day to the old one i uploaded still tweaking few things and if all goes to plan could have it up tonight

Just sorting out light's and lowering the aero bit by bit feel it has too much,only bit of info I can find is they say the car isn't very aerodynamic so engineers put all efforts into high amount's of mechanical grip.

Here is a video of the shading improvements and laps of nord visually the cars look to be correct with watching real car footage but high speed corners doesn't look right to me

Sorry for the low quailty video dont have video editing software anymore and at this bitrate took 8 hours to upload

That's looking fantastic Tovey! Is there any possibility to have the front roll bar removed from blocking the windscreen view? That thing drives my insane!

Sorry but that larry bar was there in real life as well it didn't get removed till COTF

Damn
Hey Tovey how'd you learn how to do this modding? YouTube vids or forum guides? I ask as I'm looking at the nascar vehicles and want to know how much of my life will be taken up by modding

3d side of things i've been messing around with blender for 3 and a bit years so knew the optimal path for better looking shaders physic's side of things was kind of new been tweaking drift cars for past year but never took it as serious as these car's I watched every video i could find from engineers read heaps of mechanical engineering books and read every physics post on the AC site also changing values i didn't know to the extreme so i would learn what they did

Head start for you inertia values go by length height width for front engine cars always exaggerate the length for better effect so nascar length 5.28 (Real is 5.18)width 1.91 height 1.30 wheelbase 2.79 check those numbers in the car ini then just start tweaking things and finding data

Cheers yeah it's kunos amg gt3 sound haha don't know how to make scratch sounds just yet but looking into it

so on the whole larry bar fiasco turns out the ford is a car of the future model not standard 2011 so has no larry bar....

So choice is your's guy's either 1) I add the bar to the ford 2) I remove the bar from the holden 3) leave the cars as is much less stuffing around and focus on aero to get the car's out asap

Assetto update has broken the mod!!! every mod for me is no longer working at all trying to work it out but at the moment only official car's work
