A bit of WMMT5DX+ research and an apology Standard So where have I been? Procrastinating mostly. I'm just going to be honest and say it. I haven't really been anywhere for a while. Its been a really, really, long time since I've done anything substantial on this site. There's a certain amount of guilt that I feel every time I log in, and it has gotten to the point where I feel like I need to do something about it. So I'm starting today to hopefully remedy the last three years of complete inactivity. The site will continue to be free for anyone to access and use the information listed. It is also ad free, and will remain ad free forever. Like Facebook "Its free and always will be.", even if you don't wanna use it. Do you still answer emails? Yes! Though I can't guarantee to reach out to everyone, so apologies if I missed your question. I'm going to close the comments on the site because I find it to be pretty clunky to track all the different comment threads and chains. It also slows down the site having to load so many comments. If you email email@example.com, I will answer any and all questions you have. Top Speed Testing! Below is a graph showing how top speed scales down with horsepower setting. All testing was done on New Belt Line Clockwise with the following cars for each speed range. 351km/h: Nissan GTR (R35) 350km/h: Mazda Rx-7 (FD3S) 349km/h: Mitsubishi Lancer Evolution 9 (CT9A) CSV Copy Turns out that all cars follow this nice linear graph which shows that as horsepower setting goes up and down, the speed changes in increments of 3km/h per setting. I also tested cars in the 350km/h strong range with the Nissan Skyline GTR (R34), and 349km/h strong range with the Nissan Skyline GTR (R32). The only thing that changes is how long the max speed is held for.
