Turbocharger GVW-40 Detailed Specification

1. Product Naming Breakdown

• Turbocharger: A forced induction device that uses exhaust gas to drive a turbine, compressing intake air to boost engine power.

• GVW-40:

• GVW: Likely a brand acronym (e.g.,Garrett,VariableWastegate) or series designation.

• 40: Typically indicates turbine core size (e.g., 40mm compressor wheel diameter) or engine displacement compatibility (e.g., 1.4–2.0L engines).

2. Key Specifications (Estimated)

【表格】

Parameter Typical Value Description

Compressor Wheel Dia. 40mm Determines intake compression efficiency, directly affecting boost pressure.

Turbine Wheel Dia. 38–42mm (matched with GVW-40 wastegate) Balances exhaust energy utilization for response speed vs. peak power.

Engine Displacement 1.4L–2.5L (naturally aspirated baseline) Requires boost pressure adjustment to avoid knock or excessive wear.

Max Boost Pressure 1.5–2.5 bar (ECU-tuned) Requires upgraded intercooler and fuel system.

Spool Time 0.8–1.2 sec (full throttle to target) Influenced by turbine mass and wastegate control.

3. Associated Components (GVW-40 External Wastegate)

• Model Correlation: If "GVW-40" refers to a turbocharger + external wastegate kit, it may include:

• 40mm V-Band Wastegate: E.g., Tial MVS series upgrade for precise exhaust bypass control.

• Wastegate Actuator: Spring-loaded or pneumatic, adjusting opening pressure (typically 0.8–1.2 bar).

• Mounting Bracket: CNC-machined bracket for exhaust-side installation, ensuring leak-free sealing.

4. Performance Features

• High-Efficiency Design: Lightweight compressor wheel (e.g., titanium-aluminum alloy) reduces inertia loss.

• Adjustable Wastegate: Supports manual or electronic control for optimizing low-end torque vs. high-RPM power.

• High-Temperature Materials: Turbine housing uses Inconel alloy, withstanding 900–1050°C exhaust temperatures.

5. Typical Applications

• Aftermarket Tuning: Fits Honda K-series, Volkswagen EA888 engines for turbo upgrades.

• Racing/Competition: Requires high-flow intake, full exhaust, and ECU tuning for 300+ HP output.

• OEM Replacement: Used in high-performance variants (e.g., Volkswagen Golf GTI Clubsport).

6. Installation Notes

• Piping Matching: Custom intake/exhaust pipes required (typically 2.5–3-inch diameter).

• Cooling System: Upgrade intercooler (e.g., front-mounted core) to reduce intake air temperature.

• ECU Tuning: Mandatory reprogramming of fuel injection and ignition timing to prevent knock/engine damage.
