the 3.8L twin turbo V8 used by Mclaren is pretty cool. in the 12C (their slowest car) it makes 616 hp. in the 650S it makes 641 hp and in the P1 it makes 727 hp.
I also like the 5.0L twin turbo V8 in the Koenigsegg One:1 because it make a huge 1,341 hp and more importantly a huge torque band meaning insane acceleration throughout the whole RPM range.
this is the engine that has the highest specific power output of any stock car in the world producing more than 200 hp per liter of displacement.
I also like the 2.5L inline 5 engine used in the Audi TT RS. it sounds amazing and also has a fairly high specific power output.

There's only one choice:
The Rolls-Royce Merlin.
Found in the Supermarine Spitfire, the Hawker Hurricane, the de Haviland Mosquito, the Avro Lancaster, and the North American Aviation P-51 Mustang, among others.
It was the engine that won the war.
Opps.. Total mistake. Wish could remove? Sorry
