Boost

1986 Porsche 962

This car has a turbocharged 2.8-liter flat-6 engine. It is running 75 psi of boost, which means it is pumping in five times the normal amount of air, which means it's like running a pair of normally aspirated 427 cubic inch V-8's. I sort of knew that boost pressures were going up but I had no idea they were ever this high. It used to be that a few PSI of boost, certainly less than 10, was all you could expect, and all the engine could handle. The power producing parts in this engine (the crank, connecting rods and pistons) must be made of unobtainium.
