At 4,200 RPM, the stock Duramax L5P intake valve is only open for nine-thousandths of a second. (That’s .009 of a second!) We want to run our supercharged diesel engine over 6,000 RPM so the valve-open time will be further decreased. Gale explains how our new .400″ and .500″ experimental camshafts will open the valves higher and longer, allowing for more airflow, without contacting the piston. Sharpen your pencil, school is in session.
