There is nothing wrong with using 98 and 100 RON fuel, but if you are manufacturing a car with this engine you should reduce it to 95 RON fuel for European countries and 91 RON for the Americas, Australia and New Zealand (87 AKI). It makes no sense otherwise. The car is cool, however I feel the front could look less like the bonnet go flat and then flat downwards when it ends. It is always nice to have some extent of curvature there. I suppose you will replace the lip on the rear for a wing/spoiler when the update comes out (which, from what I know, is tomorrow). Good work!
ahhh thanks reducing the octane rating will be my #1 priority then, also i was worried about the hieght and length of the inline 6 thats why the bonet is high and straigh once i get the engine in il look to lower it abit
Edit : Ok Octane rating fixed now
You probably dont need to change your engine RON or AKI because the car will run on fuel that is below that RON or AKI without actually knocking or having any issues other then the numbers of HP and Ft.-lb. will be lower as well as your eco numbers. So if you want to know what those numbers would be just change it down and tune it for running on 91 RON or 87 AKI. I would probablly tune the engine to run on premium fuel for selling so that people can have the option of using the premium fuel (if they prefer) but also use just regular fuel. I know my car is suppose to run on 95 AKI but to hell if I am going to pay the extra 8 cent/L for that so I run it on 87 AKI. The engine runs but I know that I am not getting the same amount of power or anything! I think you should be fine but dont expect everyone to be getting those econ numbers or power numbers.
