This video features Big Engines Start Up and Sound compilation If you wanna see some Big Engines in the world watch this video and if you like the video with biggest engines hit the like button. Thanks all for sending me your videos. Without you I will not be able to create all these great compilations. I hope that this co-operation between us will last for years. Thank to you all.

 Great video! Should mention the torque figure as that's what those engines were made for. :)  Preheating the head/combustion chamber on the large diesels was a standard practice on early engines such as Fairbanks Morris etc.
I believe there is a decimal place missing on the Merc cruiser Hp but that would be a maximum modified.
The sounds just don't cut it especialy on the Griffon and P&W 4360
 Man it would just be so cool to watch these engines actually power something, they are so interesting, especially this massive insane turbo diesel at 2:07
 Wright R-3350, known as "Duplex Cyclone", most powerful engine in Cyclone serie. Used in famous aircrafts - Douglas DC-7, Lockheed Constellation series, Boeing B-29 Superfortress and others.
 2:00  I always did like the kind of motor you have to set on fire to get started. Takes me back to the good old days of 3rd degree burns and steam explosions.   7:02 that blow was amazing  8:42 - This engine is not built by Mercruiser - it is a 454 Chevy big-block in marine/industrial form. For those that don't already know.  9:00 there is no way that horsepower is correct it’s probably 385.1
 The second Gardner is a "Dutch diesel" - individual torches warm the cylinder heads before the engine is cranked. It's an early trick that was later emulated by glowplugs but needs no electrical system to start and run. Archaic but cool :-)
