Auto engineering video series.
 

This guy is awesome! Now this is his first one so cut him some slack... Great series (dozens of topics on his channel) explanations from an engineering perspective.

Ok, unexpected 'Perfection in Engineering'...the GT-R!

Pretty good episodes. Keeps it pretty basic. Doesn't talk about combustion efficiency due to the increase of O2. One thing that could be argued is that while STP is approximately 14 psi, due to the increase in volume from the piston traveling down the combustion chamber, the chamber is actually at a lower pressure.

Edit: Okay, it depends on the time (valves open/closed).
