thank you for the reply. i have read the thread and that is where i saw the varying consumption figures, among other sources, thus the query from actual users specially from those who are using the closed loop system.

thank you for the reply. i thought so too that there would be some kind of a fuel consumption penalty. i cannot decide whether it would be worth it to go for the sgi or for the closed loop system, all depends on the corresponding fuel consumption penalties inherent in each of those systems.
