Эксперименты со шноркелями позади кабины пилота.
Зима, 71 Weissach Test Track, шасси 917-030
" a) Ram boxes have a worthwhile effect only if they are high enough to project well out of the boundary layer. Forward facing air scopes at body panel level, either above the cockpit or on the sides have very little effect.
b) Baffles must be fitted inside the airboxe to equalise the rame effect over the intake pipes.
c) The two ram boxes required to obtain a worthwhile ram effect on the 917 increase the drag by about 5%. Consequently there is little benifit to be expected from their use."
