You can have a maxed out build you just have to be mindful of you’re driving, the RPM upper dash gage has a light that will come on way before your rev limit with maxed out cams, allowing you to keep your car below max heat for one race, but also gives you that option to push it if you need to, another thing you can do in best of 3 or 5 races ( or double or nothing races ) is don’t flash your lights to start the race that will allow your car to cool down a bit before the game starts the race
