Dema Elgin and Allan Lockheed are hosting an Engine Performance Seminar January 18-19 in Topeka, Kansas.

Topics covered will include:

–timing and flow requirements of an operating engine, and the priority of valve events

–airflow and comression ratio vs. cam events

–the importance of valve seating velocity

–2-valve, 4-valve, supercharger and turbocharger airflow, valve events and engine operation

–tappets and cam lobes, how to recognize and avoid problems

–valve spring designs and evolution

–oil and lubrication, fuels, crankcase vacuum, pistons rings, connecting rods

–how to select cam lobes for custom cams

–managing six regulators of engine performance

–tailoring the horsepower curve to the application

–exhaust design tailored to the power curve

–identifying pressure and velocity wave models for good engine performance

–balancing airflow, cylinder filling vs. airflow and velocity, plus velocity/port sizes for each engine and powerband

–airflow requirements vs. rod length, engine speed, cylinder size and stroke length

More information is availble from Elgin at (650) 364-2187 or Lockheed at (303) 238-2414.
