Camshaft For Supercharger Or Turbo Charger (slot Drive)
This camshaft has been designed by Mini Mania for use in "A" series motors that have forced induction. These motors work best with a camshaft that is optiomized for the proper overlap and timing for a 'blower' induction system. 110 degree lobe centers.
With a checking clearance of .050", the intake opens at 11 degrees BTDC and closes 51 degrees after BDC. The exhaust opens at 51 degrees before BDC and closes 11 degrees after TDC. Duration at .018 lift is 284 degrees.
Overlap is 22 degrees at .050". Duration is 242 degrees checked at .050" and/or 248 degrees at .018"

Camshaft Theory by Elgin
Created: January 28, 2006
Considerable information has been recorded about numerous aspects of the four stroke internal combustion engine. Nevertheless, only a small percentage of people really understand how it works and even fewer still know how to modify an engine to suit their needs. I will try to simplify this complex subject by discussing some basic principles that may be overlooked or misunderstood by the average person. First, it is very important to understand the relationship between piston travel directions and valve timing events. The reason this relationship is important is because it is one of the few things that is relatively easy to adjust/change. The camshaft which opens and closes the valves makes ONE complete revolution (360 degrees) while the crankshaft moving the piston up and down the cylinder rotates TWICE (720 degrees). Camshaft timing is usually expressed in terms of crankshaft degrees relative to the piston location in the cylinder. That is, relative to Top Dead Center (TDC) and Bottom Dead Center (BDC), respectively. Note that during the four strokes of a piston in an internal combustion engine the crankshaft will rotate 720 degrees and the piston will be at each TDC and BDC twice.
