Is it just me or does it seem far too excessive? I didn't realise until I made up engine files for a KT100J based off a real dyno sheet from one of our own engines, and I could barely go over 80 km/h at Lonato. I even made sure it permanently had perfect carburetion and optimum temperatures so that I was getting full power from the engine. Using the same gearing in real life at a track with a shorter straight and a tighter corner leading on to the straight this engine easily does 90-92 km/h without draft or ducking. I had to give the engine way more power than what it realistically has to get almost normal speeds out of it, and then if I tried to duck I would get like an extra 6-7 km/h whereas in real life it's more like 1-2 km/h tops if you're lucky and there is a head wind. Just by ducking I was gaining 1.5 seconds per lap at Lonato which is completely ridiculous for low speeds in good conditions. I haven't been on track with another kart that wasn't blinking and warping all over the place yet but I imagine the draft effect is massive, can anyone confirm this?
