A previous owner of my Exige S1 opened the tailgate/roof scoop housing to change the airflow.
(See picture) However, I am afraid that part of the flow now escapes directly through the grille above with no effect.
As I understand it, the air is supposed to sizzle through the tailgate housing into the side openings/slots, thereby bringing in air from both sides.
Now I have closed this “artificial” opening with tape and blown air into it from the front with a hairdryer. I attached very thin strips (light wind ribbons) to the side slits of the tailgate.
Result: Zero. Nothing comes in at all.
Question: Can anyone explain the original air flow to me, or does anyone know about the functional principle that Lotus came up with for the S1?
Cheers,
Bernd
