[QUOTE="Voltwings, post: 13580048, member: 155561"] *comes on Mustang (sub)forum and gets mad at "mustang owners." lol Yes, with no other changes, it would take more rpms to make more horsepower with the equation for horsepower being Torque X rpm / 5252 for those wondering. Now, that leaves us with two options for making more power: More airflow velocity (read: torque) in the midrange/top end, or more RPMS, and since 6700 rpms is just astronomical lol lets start with mid range airflow. Of course since we're all engine builders and tuners here i dont need to explain how airflow effects power lol, but lets look at what our goal realistically is. 470hp. So, assuming we achieve no increase in RPM, we need to target around 370 torque at 6700 rpms. Assuming the current coyote sees 420 hp (330tq), you're realistically looking for 40 crank torque at 6700 rpms to get 470 whp... not exactly "remarkable" or "unachieveable," when you consider the heads, cams, and tuning available from the Ti-vct system. Thats also assuming we stick with a strict 6700 rpms limit, but if we bump it up to just 7000, we only need 350 torque for our magical 470hp number... again, not exactly unbelieveable. [/QUOTE]
