Semtex is more powerful than ANFO on a pound-for-pound basis. And we are talking TWICE the amount here.

Given the old Demolition FM conversion tables...10K of Semtex equals 13K of ANFO.

Still wouldn't be enough to completely destroy things like turbine rotors, et cetera. Remember, those are further from the blast hypocenter than the Ryder truck's rear axle was, and are designed to take more stress.
