First the engines are ported, polished, balanced and blueprinted to squeeze every bit of power out of them.
Also, the engine is only going to be use for one race. Friction is one of the biggest causes of both lost power and heat. To reduce friction, they can run bearings and bushings that reduce friction, but because of their design, would never last in a street engine long enough to be practical.

they have very high compression and redlines, and all the internals such as pistons, block, head, and crankshafts are usually forged and treated. Tuning, and the fuel they use also a huge part of it. Companies also pour huge amounts of money into R&D for engines models they may only use for one season so you'll find a lot stuff you never would of a standard sports car.

high compression, high voltage spark,and the fuel used is formulated for it.usually around 110 for gas,also alcohol can be used.roughly equivalent to 200 octane
