This force Penumbra has a Koenigsegg Jesko engine replica making 1500hp on 100 Octane gasoline (the original makes 1280 on 91 octane and 1600 on E85 witch is like 115 Octane or sth like that) It is... fast. And i tried to improve handling as much as possible. On the other hand: I didn't test it even until now^^
