SERA And The Porsche 917, Part Two
Pilotes Anciens: SERA And The Porsche 917, Part Two

This could be unloading for either of the two Langheck tests at the Volkswagen proving grounds, or for the LeMans
Test Days in April. In any event, the car as seen here is the "first cut" at a 1970 LH. Note the smaller rear window
without louvers. For reasons unrelated to LH aero, 1969's side exhausts for the front cylinders have been lost in
favor of conventional 6-into-2-into-1 exhausts exiting at the rear. SERA was heavily involved in this shape.

Diagram From Paul Frere's "The Racing Porsches" book depicts a similar system in use on early 917s before movable rear wings were outlawed.

Even on Laguna's long and curved front straight, the little ailerons are seen strutting their stuff.
