According to carbon4, who worked at FSI, the "supersonic" booster F100-0 had another difference. There was a layer of black powder added on top, held in with nitrocellulose dope.

I suspect that the whole supersonic thing was a bit of a trick. The "boom" was really a "bang," of that charge going off and the tight-fitting D20 popping out.
