RPM and Torque Curve

Guys, I am sorry, but I am new at vehicle creation and don’t really know, how to work with these settings. I want to make a car with such characteristics: 6.6 L V12 engine, 800 PS @ 8000 rpm, 750 N*m @ 5500 rpm, 3.0 s acceleration, 350 km/h top speed. How do I calculate this numbers to get exact result through editor options? Thank you.

Oh. I guess, I have to figure it out by myself.

****. I think, I am still stuck.
