The foam is not there to add speed. It is there solely to dampen the sound and feel.
It is the club weight distribution and spring like effect of the face that adds speed.
Although you may be right, the marketing guys at TM say this:
SpeedFoam™
An ultra-light urethane foam injected inside the head that’s engineered to push the design limits of face speed while simultaneously improving feel.
