Power Curve

Please help! I have only short question about an engine. I´m a student of Czech technical University in Prague and I´m working on my diploma project about Infinity. I need necessary the power curve of 3,5 liter engine (kW and Nm -> rev or in english units). I´m not able to find this curve anywhere in english websites (maybe because I´m not native speaker). This is conference about the car with this engine so I hope there is anybody here who can help me. Any link or other information will be very helpful for me. Thanks a lot.
