RE: Transom Soot

As I understand it, too much exhaust back pressure can also contribute to soot. Basically, the more air through the engine, the better. This means large air filters with minimum restriction and minimum lift in the exhaust system. Also, try to get cool (denser) air to the air filter. Even a turbo in good shape will struggle if the installation isn't good.

Just my inexpert opinion backed up with little knowledge and less experience.
