We explore acceleration of ions in the Quark Nova scenario. Two cosmic ray
components are isolated: the pulsar wind (before the explosion) and the
propeller wind (following the explosion), both boosted by the
ultra-relativistic Quark Nova shock. The latter component acquires a power law
spectrum (${
m d}N/{
m d}Esim E^{-s}$) with $ssimeq 3.2-3.3$ and energies
$10^{15} {
m eV}<E<10^{18} {
m eV}$ while the former, boosted pulsar wind,
achieves ultra-high energies $E> 10^{18.6}$ eV and a spectral index $ssimeq
2$. We predict up to around 50 simultaneous ultra-high energy cosmic ray events
for the Pierre Auger detector per distant QN, pointing back to the original
direction, while about 1500 are predicted for the proposed EUSO and OWL
detectors.
