For a long time, I've been curious about how the engines in GPM2 work, as they're important for modding the game. As we've learned over the years, getting the teams to perform accurately takes time. I tried to gain a better understanding of the engines by running some experiments within the game. I used the same circuit from Japan, (Suzuka), with a driver that is rated 5 stars in every area. The car was always the default one you start a new career with. The weather conditions for testing was always sunny. I put the car through the testing and qualifying.
The first stage of the experiment involved seeing how increasing the engine horsepower by 20 affected lap times. The results showed that 20hp is worth about half a second. It's worth noting that once we reached 670hp, the times didn't significantly improve.
The second part was to only change the weight of the engine, making it gradually lighter each time. This didn't change much, as the difference between 170kg and 110kg in testing was only about a second, but qualifying created some weird results. I repeated these tests 5–10 times to make sure it wasn't a fluke, but oddly, even if your car was now lighter it may cause it to slow down sometimes.
I observed that simulating the race (viewing it live) resulted in faster lap times for your drivers. Yet if you skipped the live results, you'd be 4 to 5 seconds slower. This was tested several times, so watch it live if you want to be faster in qualifying.
Is the engine's performance affected by the star rating? No, a one-star engine performed just as well as a five-star engine; I believe the ratings are based on reliability, and they do not influence the speed.
This experiment's final test and conclusion. I modified the weight and engine power at the same time, with the engines becoming lighter and more powerful as time went on. The findings appeared to be more consistent, and I didn't notice any unusual lap times this way. In both testing and qualifying, adding 20hp and taking away 10kg resulted in lap times that were exactly one second faster on average. I'd guess adding 10 hp and taking away 5 kg is worth about half a second. With this data, I hope it will be easier to balance out the teams in the mods.
