Using F1 as a reference, I think you should be able to make a ton of hp out of 2 liters.
I remember reading about the F1 engines, and how they need to be kept at near-running temperature even during transportation because of the tight clearances. The BMW team circulates heated coolant through the engines even while they're on the airplanes heading to the events.
