I asked Lotus and here is their reply: No damage, only restricted power.

LOTUS REPLY BELOW:


I hope you are enjoying your Exige S.

I copy below an extract from page 68 of your Owner's Handbook, which I hope
answers your question. Yes, the efficiency of the chargecooler will be
adversely affected.

Exige
The Lotus Exige has been conceived and configured as a sports coupé with a
removable roof. The aerodynamic performance of the bodyshell including the
front spoiler, rear aerofoil, roof panel and tailgate have been tuned to
provide the optimum handling balance, with the roof scoop on supercharged
cars providing the cooling airflow for the chargecooler.
The roof panel may be removed for better access to the interior for
servicing, and the car may be driven without the roof fitted, but wind
buffeting and increased noise levels will be experienced, together with a
slight decrease in maximum power on supercharged cars.
