FERRARI F8 F142MFL Turbocharger Left

Ferrari F8 Tributo (F142MFL), the left turbocharger is a highly specialized component that evolved from the 488 Pista. Unlike the standard 488 GTB, the F8 uses the upgraded units derived from the 488 Challenge race car.

1. Technical Specifications

The F8 uses IHI twin-scroll turbochargers. The key differentiator for the F8/Pista turbos compared to earlier models is the integration of turbo speed sensors, which allow the ECU to push the turbos closer to their physical limit without over-speeding.

• Manufacturer: IHI (Ishikawajima-Harima Heavy Industries)

• Model Series: VU25 / VU26 (Specific to the F154 CG engine)

• Side: Left (LH) – Driver’s side on Left-Hand Drive vehicles.

• Key Feature: Lightweight titanium-aluminum (TiAl) turbine wheels for reduced inertia and virtually zero turbo lag.

2. Part Identification

When sourcing this part, ensure it is the version with the speed sensor port. The left and right units are not interchangeable due to the mirrored orientation of the housings and wastegate actuators.

• Ferrari Part Number (Left): Typically #342133 (Verify via VIN as supersessions occur).

• Associated Hardware: * Turbo Speed Sensor: Often sold separately from the core unit.

  • Oil Feed Line: #328456 (Recommended for replacement during turbo swaps).

  • Gasket Kit: Necessary for the manifold and downpipe connections.

3. Key Differences: F8 vs. 488 GTB

If you are looking for this part for a project or repair, be aware that the F8 unit is a significant upgrade over the standard 488 GTB:

• Performance: Capable of supporting the 710 hp (720 cv) output of the F8.

• Sensors: The F8 turbos have a dedicated port for the speed sensor that monitors RPM; standard 488 turbos do not.

• Weight: The internal rotating assembly is lightened to improve throttle response.

4. Installation & Service Notes

• Cooling: The F8’s intake air cooling is improved by 15°C compared to its predecessor. Ensure the intercooler ducting is perfectly sealed during installation to maintain this efficiency.

• Oil Priming: As with all high-performance ball-bearing or journal-bearing turbos, the unit must be primed with oil before the first start to prevent immediate bearing failure.

• Wastegate Calibration: The electronic wastegate actuators are precision-calibrated. If the actuator is moved or replaced, a Ferrari-specific diagnostic tool (DEIS) is required to perform the “Self-Learning” procedure.
