The components look stout from the pictures. There's a lot of mass in the valvetrain with the chains and Vanos components. How does the combustion chamber/port design/valve profiles look? Do you think the roll off of power at redline is due to head flow limitations, valve size, cam profile, a combination? Just wondering where the best bang for the buck is to get more power out.
damn reading that made me dizzy
