[OT] My Other DD VW Car - not really ot

[t.piwonka at ttu.edu (Robert Piwonka)]

He must of been referring to gravitaonal force.  However, for one bank of 4
cylinders faceing downward at a 15 degree angle, I believe 2 pistons would
be going up and 2 going down the majority of the time(other than when
changing directions) so 2 would always be working with gravity and 2 against
just like in any other non-boxer motors.
