Judging by your post you are no doubt interested and definitely targeting in question. I can inform you that my research with regards to the suspension and tires have been crowned with success, and in General found an excellent basis for a realistic physical model. The first to work out the Mercedes C9. Now an important aspect of adjustment and tuning of the engine and gearbox. What is required. At 7000 rpm (720 bhp - power I already asked) it is necessary that the machine under certain settings accelerated up to 370 km/h (5 speed Manual!). Such tests can be carried out for example in the LeMans 1979. Further, the engine he so to speak immortal)), not too hot, never burn out, and apparently practically does not wear out. But the dynamics and the turbo effect provides excellent. If you find other varanty, without a doubt will be the meaning of the review. And if you have no time or opportunity to provide such help, please report it to. Then I'll rely only on their own strength. P.S all the necessary materials for work is ready to give you in any convenient for you time. That is the basic mod and developed by the car. - Mike Becnel wrote:

I am downloading the files at the top of this topic to see the history of the mod.
Thanks for working on this!
The cars of the Group is in my opinion the most interesting phenomenon in the history of Motorsport and modernization quite in vain not shown due enthusiasm and now we don't have any qualitative modifications on this topic. | |

Hey Vadim, Thank you for your message. Do you use Google Translator? I try to write very simple. The engine does practically not wear out. That is correct. It is able to last the race distance. What we can research: Where are the limits of the engine. Do you have information from the history, how many RPM the engine could stand "forever" and how many RPM would wear the engine down? Does the Turbo have an air restrictor or a maximum pressure? The former mods have engines which u can always run at maximum settings. At my Watkins Glen race (6 hours) my first teammate told me, that it is better to run the engine not on full rpm, but that was not correct. They can last the race distance many times. In reality excessive heat and rpm can destroy the engine easily within 24 hours. Remember 2010 or so, the Peugeot all failed at 23,5 hours. I very much like to give different cooling options on the car, because: If you are a driver that drives a long 5th gear you can use less cooling. at 400rpm below maximum u save 2C or 3C and mechanical wear. i definately want to add cooling options that are also too less cooling, like in the 1991 F1 mod, where brakes and engine can overheat. Different Temperatures of the air also must be considered for the car set-up. I very much appreciate to work out a setting, where the engine will heat up 4C or 5C over the usual temperature on a long straight. Because in rFactor the engine is -mainly- cooled by the water circuit. And there is a bottleneck in the heat transition, which is not simualted in the mods we drove already. I have not researched: If you can adjust the brake disc wear depending on the temperature or if this is a fixed value by rfactor. | |

| So, the work on the physics of Mercedes C9 passed the stage of the alpha version and is ready to move in beta. Suspension is almost ready, there may be no significant adjustments. I am convinced that its work is very, very close to the real behaviour. But the most difficult moment in the study of physical models of these machines, it is the creation of realistic dynamics. Having studied the many and often conflicting sources, which constitute in most cases. The machine reached a top speed of 370 km / h and had the dynamics from 5.7 to 6.3 seconds during acceleration up to 150 km / h. Apparently depending on the quantity of fuel or likely setting the gear box. The images are presented some results of my work in this direction. ![rFactor Mazda 787B - Page 2 Rfacto24](https://i.servimg.com/u/f31/17/61/20/19/rfacto24.jpg) ![rFactor Mazda 787B - Page 2 Rfacto25](https://i.servimg.com/u/f31/17/61/20/19/rfacto25.jpg) Similar results I seem to be encouraging. However, still remains to be a serious work on the wear and tear of the engine and temperature characteristics. It seems to me that the more eloquently I speak, the more foolish it is translated ![rFactor Mazda 787B - Page 2 420535](https://2img.net/u/2915/69/36/76/smiles/420535.gif) . One of the Safety Car..I am sure that in excellent mod, must be full-featured Pace Car. To add another Mercedes 190å... ![rFactor Mazda 787B - Page 2 Rfacto26](https://i.servimg.com/u/f31/17/61/20/19/rfacto26.jpg) | |

| Vladim,
Be aware that the wheel a player is using will have a dramatic impact on how the car feels to each player. It is a game, not a real car. I just upgraded from an old FFB wheel to a G27. All my old setups are now completely undriveable.
My point is you should leave a large amount of room for people to adjust the cars even if that slightly lowers the realism. A realistic mod that only those with the top equipment can use will likely fail. | |

If I understand correctly, you believe that in the settings of the car will be fixed or not functional. It is just the opposite! Possibility of adjustment of vehicles will be very broad and allow to set up the car as you wish. I only gave an example of the car, in which he attains its maximum speed of opportunities! Moreover the fashion to add the plug-in and settings upgrades, which will allow a fully featured used gearbox and clutch the G25 and g27 for example. | |
