Dema Elgin and Allan Lockheed are presenting an Engine Performance Seminar April 6-7 at Pete’s Harbor in Redwood City, California.

The seminar will focus on the development of multi-valve high-rpm engines, including tailoring the power curve to the application; exhaust design; balancing airflow, cylinder filling versus airflow and velocity, velocity/port sizes for powerband; air flow requirements vs. rod length, engine speed, cylinder size and stroke length; cam design; airflow and compression ratio versus cam events; valve seating velocity; cam lobe and tappet problems; valve spring design; and other related topics.

More information is available from D. Elgin Cams at (650) 364-2187 or Allan Lockheed & Associates at (303) 238-2414.
