  We present the discovery of 8 isolated millisecond pulsars in Globular
Cluster (GC) NGC 6517 using the Five-Hundred-meter Aperture Spherical radio
Telescope (FAST). The spin periods of those pulsars (namely PSR J1801-0857K to
R, or, NGC 6517K to R) are all shorter than 10 ms. With these discoveries, NGC
6517 is currently the GC with the most known pulsars in the FAST sky. The
largest difference in dispersion measure of the pulsars in NGC 6517 is 11.2
cm$^{-3}$ pc, the second among all GCs. The fraction of isolated pulsars in
this GC (16 of 17, 94$\%$) is consistent with previous studies indicating an
overabundance of isolated pulsars in the densest GCs, especially in those
undergoing cluster core collapse. Considering the FAST GC pulsar discoveries,
we modeled the GC pulsar population using the empirical Bayesian method
described by Turk and Lorimer with the recent counts. Using this approach, we
find that the expected number of potential pulsars in GCs seems to be
correlated with the central escape velocity, hence, the GCs Liller 1, NGC 6441,
M54 (NGC 6715), and $\omega$-Cen (NGC 5139) are expected to host the largest
numbers of pulsars.
