  We study the occurrence of delayed SNe~Ia in the single degenerate (SD)
scenario. We assume that a massive carbon-oxygen (CO) white dwarf (WD) accretes
matter coming from a companion star, making it to spin at the critical rate. We
assume uniform rotation due to magnetic field coupling. The carbon ignition
mass for non-rotating WDs is M_{ig}^{NR} \approx 1.38 M_{\odot}; while for the
case of uniformly rotating WDs it is a few percent larger (M_{ig}^{R} \approx
1.43 M_{\odot}). When accretion rate decreases, the WD begins to lose angular
momentum, shrinks, and spins up; however, it does not overflow its critical
rotation rate, avoiding mass shedding. Thus, angular momentum losses can lead
the CO WD interior to compression and carbon ignition, which would induce an
SN~Ia. The delay, largely due to the angular momentum losses timescale, may be
large enough to allow the companion star to evolve to a He WD, becoming
undetectable at the moment of explosion. This scenario supports the occurrence
of delayed SNe~Ia if the final CO WD mass is 1.38 M_{\odot} < M < 1.43
M_{\odot}. We also find that if the delay is longer than ~3 Gyr, the WD would
become too cold to explode, rather undergoing collapse.
