1 hp = 746 watts. 35Kw = 47 HP. That's as far as you can go. There is no correlation between displacement and HP. Engineers can take a 2000 cc engine with 65 hp and modify it to develop 250 HP. It might still be a 2000 cc engine, but with better fuel delivery, super charging and other modifications makes it a much higher HP engine. In other words, you can have a 35Kw engine with a 2000 cc displacement and a 35Kw engine with a 4000 cc displacement.

Impossible to answer simply because there is more than one way to design an internal combustion engine and power output is not directly related to engine displacement.

not possible ...just look through history ...in the 1920s they often had engines of massive capacities ie 27000cc..yet only produced bhp of less than 300 ..less than half of a modern formula1engine of 1500cc

Hi jack is right that is exactly the situation so time to learn about power engineering kiddo.

There is no linkage. You can change KW to BHP but cubic capacity is not related.

Imposable, could be a huge engine with low output or small engine with high output.

38kw is 648cc in a Tata Nano.
