Kevin Shasteen Posted June 10, 2001 Share Posted June 10, 2001 Does anyone know of any site/books where I can find actual figures for airflow in a DOHC cylinder head. I'ld like to know how mfg's determine what size valves are required; also what comp.ratio is needed based on the size of their valves -vs- expected output of an engine w/multiple valve cyl.heads(?) I'ld also like to know what math/formulae are used in making those determinations. Any response would be appreciated. Quote Link to comment Share on other sites More sharing options...
