Turn the Volume Up!
In this video, we see the head mechanic running up to 40 inches of mercury on the Rolls Royce Griffon engine as the Precious Metal team makes preparations for the Reno Air Race in 2014.

We absolutely love those contra-rotating props, as well as the beast that’s the Rolls Royce Griffin engine. What an awesome engine in an awesome plane.

You might also notice that the fourth cylinder from the left is richer and leader than the rest. Our guess is that it’s richer from the startup.
