Camshaft overlap
http://www.iskycams.com/cam-degreeing.html WebFeb 22, 2007 · One of the reasons for wide LSAs on forced induction engines is reducing overlap. Having them open together for too long just blows fresh intake charge right out the exhaust valve. The proper overlap is therefore necessary. I'm not good with blowers, but I know that many turbo cams have ZERO overlap. T techinspector1 Registered Joined …
