Um my first post on this forum so be gentle please...
I'd say that chains are superior to belt driven... BMW favours chains over belts and the BMW motors are legendary. Having stuffed around with a few belt driven Toyota motors (4AGE's, 4AGZE's) I'd have to say chains are more likely to support higher horsepower, provided the standard of manufacture holds up.
Oh and being a new owner of a 1.8TSI 5spd manual Octavia Wagon. I'd have to say that these are a very refined yet cheeky motor. It's the kind of motor my missus can tootle to the shops and Uni with, yet when driven hard this thing pulls harder and longer than a 16 year old teenage boy who has just discovered what his 'little mate' is for...
We get around 8.6L/100kms using premium ULP.
