i have to do a junior report and i get to pick what ever i want so i picked "How four cylinder engines work, and why do four cylinders perform better at high rpms than V-6's and V-8s." can anyone help me by giving me some sites that talk about how they work or why they perform better at high rpms, cause i have to have source cards. thanks
