Started working on this

Quote from versiu :

U can adjust caster by adjusting Half Upright Lenght and Upper/Lower Arms Lenght.
Caster in setup is more for correction and real caster can be different. Look at suspension diagrams, not setup values.

This is caster. You can't change that angle with arm lengths. I think you're thinking of camber.

Dennis Lind can not attend the race, is it ok if Danielle attends?

You'd think modelling a kart is simple

Thought i'd give these beasts a try. 100Hp, just over 200kg with driver included and banned from racing at Monaco because they are too close to F1 laptimes for the FIA's liking.

Physics close to what i want, should release it this week some time.

Livery

Graphically the car is pretty much done. I'll release it when i'm happy with the physics.

Added oval config:



Interior texturing done:



Thanks Jonathon

What a beauty

Almost ready

As you can figure out by now I am a big fan of historic racecars

Quote from Gutholz :

The description says "Central driver position" but it really is right-hand-drive. Can you make driver-side swappable?
Respect for the original 3d model.

It really is just an offset central position rather than a 2 seater. No cars were ever produced with left hand drive.

Thanks for the kind words everyone!

I really love the car. Have driven it a lot! But one thing that would really be nice to fix is lowering the engine inertia. It really should be much lower. I know that can cause rear locking on braking, but there are other ways to fix that like suspension geometry or variable engine braking.

Keep up the good work!

The sportscar is from the early 90s group c era which i really love. The thing has ridiculous amounts of downforce for the time (way more than F1 cars of that time). It also has that glorious V10 engine






Ready for import

Cool man, I do understand that this will always be a bit of a handful/ challenge, these old cars were driven by real legends!

Keep up the good work, it's exciting trying to tame such a beast!

I do think the engine "tuning" can still do with some work though, while it is fairly low revving its not that low, you can hear in the video that it revs pretty high for an old school V8.

I also found this for the M8F: https://www.supercars.net/blog/1971-mclaren-m8f/

This is from the article:


I'll adapt the power/torque to that info. It's only 600rpm off though. Although it's a later car with a different engine, i'll take any kind of data i can get for these things. Also keep in mind, the limiter is above the optimal rev range and the red line on the clock indicates the shift point - as they would do it back then.

I'll also keep working on the suspension. Because of the weight distribution, the front is super sensitive to any kind of change which makes it tricky.

Quote from M3THANOL :

I can't speak for what the real car is like to drive but this thing is so unforgiving its scary! I have found the front to get very light on high speed turns and over crests and then the rear will just break loose without warning in the low speed corners ( I know big slicks tend to have lots of grip to the limit and then suddenly let go ). However, the power delivery feels off, its too sensitive at light throttle, I know its a big V8 with torque but in a racing application you usually have the power higher in the rev range/ aim for a linear power delivery. Overall, I think this is on the right track, looks good, sounds good but the suspension needs some work. You also have too much offset on the fronts, it makes it violently snappy when you loose traction under breaking, try extend your control arms and reduce the offset to as low as you can.

Thanks for the feedback! I'm for sure not done tweaking the physics yet. You have to remember though that these cars are unlike any other racing cars we usually drive in simracing. It has an F1 level power to weight ratio, but almost no downforce - especially on the front. When it comes to the engine, it's also not a typical racing engine. It's a low revving 7.6 litre V8, so to get the power figures, you also need the torque.

This video was my main reference when making the car, apart from any data on the car i could find:


Pretty much the only one driven by a competent driver i could find.

When it comes to the high speed push you mentioned, it's mostly down to the default setup. It's on the safe side with the rear wing. If you use around 3-4 degrees, the car is a lot more neutral. Don't expect much front downforce from a car like this though - it's from 1971. Thanks again for the feedback, i'll keep tweaking it. It will never be easy to drive just because of what it is though, haha.

Looking good! Best of luck!
