Can you give a source for that please ?
If that is the case then it makes all the difference.
Accodng to TEI’s site the width is 86cm and the height (which includes all the other paraphernalia) is 110cm. So one would think the diameter is close to 86cm.

But if it is 62.4cm as you say , then the difference in thrust is self explanatory.
Besides, f404 has a three stage LP fan section that does deliver a great deal of air in to the HP compressor section against our TF6K’s 2 stage LP fan section.
