instead of setting the speed directly, you could
calculate a single "clipping" force:
dBodyGetLinearSpeed - (direction * MAX_SPEED)
and multiply it by the mass of the body (dMass.mass):
clip_force = ( dBodyGetLinearSpeed - direction*MAX_SPEED ) * dMass.mass;
Then it is ready for a proper
dBodyAddForce(clip_force);
just my 0.02f
