psi punch measurements?

[Snakey]

Dose anyone know the psi punching power pf mike tyson,george foreman, lennox lewis,earnie shavers etc . I heard shavers is 1600 psi . Can anyone verify this?.

Ivan Drago........2600 psi or so wasnt it? but he was on steroids so that isnt really fair.

Didn't he punch like 10 times harder than an average heavyweight or something stupid.

Actually i think at one point his psi measurement got to the point where he hit hard then a fuckin mach truck. Realistic for sure
