Hey! the Chapperall is my favorite car, and has large potential!!! to make it go, you need to buy a 90,000 credit turbo upgrade, then stiffen the suspension, turn up all of the traction control systems, and set the transmission to 19 - 21 .it can easily reach 237 mph on long , large tracks. i have used it in the profesional , extreme, and endurance races. even though it accelerates slow, it will win in large , fast courses. but dont get me wrong, it gets 2nd-3rd if you dont try on normal courses. it is a very odd car, but i like it. but, it has its limits, and it is NOT the best car you can get. i am currently saving up 4,500,000 credits to get , uh, well, i dont know what.
hope u use the settings, happy racing !
