jt1 Posted October 13, 2006 Share Posted October 13, 2006 It wouldn't be absolutely necessary, but a larger cam would complement the higher comp nicely. Higher static comp plus a smallish cam will give a high cranking psi and high dynamic CR, which means harder starting and higher octane requirements to avoid detonation. You would gain performance by raising the static CR, but you would gain even more with the CR plus a larger cam, as long as the cam didn't exceed the airflow capability of the rest of the engine.

grumpyvette Posted October 16, 2006 Share Posted October 16, 2006 short answer, the piston compresses NOTHING untill both valves are closed, and it takes cylinder pressure to make power or cause detonation,detonation, is the result of higher than ideal cylinder heat, high cylinder pressure and lower than ideal fuel octane, or in some cases bad fuel/air mix ratio or ignition curve/advance read the links/SUB LINK INFO http://forums.hybridz.org/showthread.php?t=93155&highlight=dcr http://www.chevytalk.org/threads/showflat.php?Cat=0&Number=1137028&an=0&page=0#Post1137028 http://forums.hybridz.org/showthread.php?t=110913&highlight=dcr Quote Link to comment Share on other sites More sharing options...
