Novitec Alfa Romeo 8C Spider adds boost for a sensuous 600 hp

Novitec has laid hands on the near-perfect Alfa Romeo 8C to create the 8C Spider Kompressor, a car the tuner claims is the “most powerful street-legal Alfa Romeo of all time.” Heady words, but they're nicely backed up by a supercharged version of the 4.7-liter Alfa V8 cranking out 600 hp and 434 lb-ft of torque. That's up from approximately 450 hp and 346 lb-ft on a stock Alfa Romeo 8C Competizione. Tweaks supporting the force-fed mill include a water-to-air intercooler, custom injectors and revised fuel and ignition mapping, plus a variable stainless-steel exhaust system.
