I just googled 2150psi for shits and giggles and found this:
Ivan Drago - Wikipedia, the free encyclopedia
Drago is characterized as a tall (6 ft 5 in or 196 cm) and powerful amateur boxing champion from the Soviet Union, as well as a former Olympic gold medalist.[2] He is also a Captain in the Red Army and as seen on his chest, is a recipient of the Hero of the Soviet Union award. He is billed at 261 pounds (118 kg, over 18 ½ stone). Drago's reputation is that of a superman; he wields a super punch of 1850psi, although some measurements captured Drago at a staggering 2150psi, whereas the average psi for a boxer is 700psi.[3] Drago is carefully fitted and trained to be the consummate fighter, with his heart rate and punching power constantly measured via computers during his workouts.[4] Drago is seen receiving injections in the movie (presumably anabolic steroids, though this is never explicitly stated).[2]
