N74B66A

Production History

  • Wraith Black Badge (Series II, 2017-2023)
  • Wraith Black Badge Black Arrow Limited Edition (2023)

Known Failures

  • Twin-turbocharger failure - high-boost operation causes bearing wear and oil leakage from 40k miles.
  • High-pressure fuel pump degradation - direct injection pump loses pressure, causing misfires and hard starts.
  • Coolant leak from V12 valley gaskets - plastic components crack under heat cycling, leading to overheating risk.

Production History

  • Wraith Black Badge (Series II, 2017-2023)
  • Wraith Black Badge Black Arrow Limited Edition (2023)

Known Failures

  • Injector failure on direct injection system - carbon buildup causes clogging and uneven fuel delivery across cylinders.
  • Oil leak from turbo feed lines - heat-related seal degradation leads to oil consumption and smoke under acceleration.
  • Timing chain guide wear - plastic guides deteriorate on high-mileage units, causing rattling noise at startup.

Can I fit a standard Wraith engine to my Black Badge-

No - the Black Badge requires the uprated N74B66A engine delivering 632PS and 870Nm torque; fitting a standard Wraith N74B66 engine will result in significant performance loss and calibration mismatch.
