We successfully use knock sensors in turbo Corvairs... and Audi's and
SAAB's... etc. Were you going to turbocharge (or supercharge) an A
series engine, the use of a knock sensor would let you tune/boost
"closer to the edge" and hopefully retard timing before you could sense
a problem. In a detonation-prone Corvair, it's the difference in the
engine surviving over 10psi of boost. In the other cars, it's more of a
precautionary safety margin.
However, turbo cars are a special application and I agree with Frank
that it's unnecessary for a normally aspirated engine.
