THE BIT THEY DIDN'T PUT ON THE BOX.
Horsepower is expensive. Alternators need not be.
Ferrari pulled the standard Denso alternator from premium high-trim Alfa Romeos for its mid-engine V8. Sourced from a Ferrari catalog, the unit is roughly £700–$900; sourced through standard Alfa Romeo or Denso industrial distributors, it is £150–£200.
SO WHAT'S THE CATCH?
Pulley, mounting, connections and charging control must match.
