A few months ago I got permission to use the works of Iaroslav Zavialov's great 3d exterior P935/K3 model.

It started as a "would it be possible project", but now I have spend 2 months learning about the 935/K3 and getting it to rFactor2.
There are still so much to do, but hopefully soon I can release a test version to get input from others.

I have spend some time making a cockpit with great details trying to get it as realistic as I can manage. But I have added a optional classic digital display, since these cars dont have a speedometer.

Thx for all the likes and comments. I want to point out that the exterior is 99% Iaroslav Zavialov's work which was perfect for converting to rf2.
@redapg and @Nick9320 I might take you up on this, but for now I'll focus on getting the engine ready.

Fun fact, this car have an incar adjustable turboboost knob. But I have set it, so that if you go full boost for more than some laps, it will overheat and break the engine.
I'm still fighting to get the boost gauge needle steady when going full boost, but think I have located the problem.

I have used some sound files from the RSR 1973 from steam, I have tried getting in touch with the author (Sderenno) to ask permission but no success yet. Unfortunately making sounds is not my specialty so hopefully this will be okay....

You could try the Sounds from the GTR2 Porsche 996 GT2, that should be OK to use these, i guess. :)
 
@Corti thx for those specs, it really helped alot.
Haven't got around to read the rest of the pages yet.

I now have the engine & gears tuned in and finetuned some physical settings.

@redapg, what car specific are you mentioning, link?
 
Hello Thomas.

Man this car is a blast to drive!!
When i was a kid i had a miniature of it in a MOMO livery, loved it!

Keep it up and lets wait for the next release.

Thanks.;)
 
@dumpberdog, I'm glad you like it.
In the quest of research of the 935 and more specific the K3 version, I realized there were a ton of versions of the 935, even though the livespan range is about 4-5 years or so.
Since this 3d model is specific a Kremer v3, I have, for now, kept the historical liveries to only being Kremer versions, but maybe I'll make a momo livery some day (which is a 935J or a mobydick variant). I have material for about 8 more Kremer liveries which I wish to make at some point, since it could be cool to have a 20 car field or more.

There will be a week pause on this project, since I'm going on a small vacation where hopefully I'll get to see a 935 irl as a spectator at Oldtimer Grand Prix this weekend.
 
Updated to test version 0.54, with much improved setup values removing the boaty feeling.
It still needs improvement, but better than before.
For instance the car feels ok at nurburgring gp, but damper feels grainy at Donington.
Those rear tires could use some more grip.

I had to test it in an Oldtimer environment even though the zakspeed is in a "grey area".
Link to the two other cars is in the video description.

In the last few days I have added these 5 historical liveries to the mod.
There is something satisfying in hunting down old photo material, old logos or even recreating logos to make them as historical as possible.
