Re: Mystery cam

["Bruce Bell" <bbell@surview.com>]

First, if it is indeed from an '82, it is not a hydraulic lifter cam.  In
the second place, unless you want the torque peak to happen at a lower rpm,
then this isn't an upgrade. Factory Audi turbo cams do not have any
appreciable overlap. Generally they have none.  As a rule, as the overlap
increases, the torque curve moves higher in the rpm range.  With a turbo
obstructing the exhaust (read back pressure) the cam is designed with little
or no overlap as an anti-reversionary  measure. Also, because of that
obstruction any scavenging effect from the exhaust pulses which would be
beneficial to a normally aspired motor are lost.
