Nissan Patrol Y62 4.0L VT Supercharger Kit: Up to 40% More Power from the VQ40 Engine
Quick Summary
The VT-V105 twin-screw supercharger kit is a bolt-on forced induction solution designed specifically for the Nissan Patrol Y62 4.0L VQ40 engine. Dyno-verified results show output climbing from the factory 279 PS / 394 Nm to approximately 385 PS / 500 Nm — a gain of roughly 38% in power and 27% in torque. The kit includes an integrated water-cooling system with dual radiators and full hardware for a clean engine bay installation.
What Changed
This listing reflects the current-generation VT-V105 supercharger platform. Compared with earlier VT units for the Patrol Y62, the V105 features a redesigned rotor profile with an optimised twist angle that improves inlet compression efficiency. VT reports a 12% efficiency gain over the previous generation, along with an expanded operational range of 18,000–24,000 RPM. The integrated cooling package has also been upgraded to a dual-radiator layout combining air-cooled and water-cooled circuits for better sustained heat management.
If you are comparing this kit against older VT Patrol listings or third-party resellers, confirm that the unit supplied is the current V105 revision with the updated cooling package. For the full range of Nissan supercharger kits, check the AME Motorsport catalogue.
Vehicle / Engine / Fitment
| Spec | Detail |
|---|---|
| Vehicle | Nissan Patrol Y62 |
| Engine | VQ40DE — 4.0L naturally aspirated V6 |
| Factory Output | 279 PS / 394 Nm |
| Supercharger Unit | VT-V105 twin-screw mechanical supercharger |
| Cooling | Integrated water cooling with dual radiator system |
| Kit Type | Vehicle-specific (not a universal conversion) |
This kit is engineered exclusively for the Patrol Y62 4.0L platform. It is not a universal supercharger adapted with generic brackets — the mounting points and piping layout are all VQ40-specific. The design retains the factory air filter housing, which helps keep inlet air temperatures lower and cabin noise closer to stock levels.
Performance / Driving Change
Dyno-Verified Results
Testing was conducted on a Mainline four-wheel-drive chassis dynamometer measuring wheel output — not flywheel estimates.
| Metric | Stock | Supercharged | Gain |
|---|---|---|---|
| Power | 279 PS | 385 PS | +106 PS (+38%) |
| Torque | 394 Nm | 500 Nm | +106 Nm (+27%) |
The power delivery curve follows the same linear shape as the factory engine. There is no sudden surge or lag — boost builds proportionally with engine speed, which is characteristic of a mechanically driven supercharger versus an exhaust-driven turbo. Throttle response remains immediate at any RPM, with the strongest improvement felt in the low-to-mid range where the Patrol spends most of its driving time.
Real-World Driving Impressions
Owners report noticeably stronger pull during highway overtakes and uphill climbs — scenarios where the stock VQ40 can feel underpowered given the Patrol's 2.5+ tonne kerb weight. The mechanically driven setup means there is no perceptible delay between throttle input and power delivery, which makes the vehicle easier to drive smoothly in stop-and-go urban traffic compared to turbo conversions.
Because a supercharger is crankshaft-driven rather than relying on exhaust gas volume, boost pressure remains more consistent at elevation. This is a practical advantage for owners who drive in mountainous terrain or at high altitude where turbocharged vehicles typically lose efficiency.
Product Comparison: Supercharger vs Turbo for the Patrol Y62
For Patrol Y62 owners evaluating forced induction, the decision often comes down to mechanical supercharger versus turbo. Here is how the two approaches compare on this platform:
| Factor | VT Supercharger | Turbo Conversion |
|---|---|---|
| Throttle Response | Immediate — belt-driven, no lag | Delayed — requires exhaust spool time |
| Power Delivery | Linear, proportional to RPM | Peaky — sudden boost onset |
| Low-Speed Torque | Strong from idle | Weak until turbo spools |
| Altitude Performance | Consistent — crankshaft-driven | Reduced — less exhaust energy at altitude |
| Heat Management | Lower exhaust temperatures | Higher exhaust heat, more cooling needed |
| Complexity | Simpler — no wastegate, BOV, or exhaust modifications | More complex — requires exhaust work, oil feed lines |
| Noise | Quieter with factory air filter retained | Louder with turbo spool and BOV sounds |
For the Patrol Y62 specifically, the supercharger route is often preferred because the vehicle's use case — heavy towing, off-road, and long-distance touring — benefits more from immediate torque and altitude stability than from peak horsepower at high RPM.

Buying Notes
What Is Included
The VT Patrol Y62 4.0L supercharger kit ships as a complete hardware package:
- VT-V105 twin-screw supercharger unit
- Mounting brackets (vehicle-specific)
- Complete intake and intercooler piping
- Integrated water-to-air intercooler
- Dual radiator cooling system
- All necessary hardware and gaskets
Installation Requirements
- Professional installation recommended. This is not a weekend garage project — the kit requires correct belt routing, coolant plumbing, and mechanical expertise.
- Retain factory air filter. The kit is designed to work with the OEM airbox for quieter operation and lower inlet temps. Aftermarket pod filters are not required.
- Post-install inspection. After fitting, a thorough check of all boost connections, coolant lines, and belt tension is essential before sustained driving.
Warranty
VT provides a two-year warranty on the supercharger kit when installed by a qualified technician. Keep installation records and proof of purchase for warranty claims.
Who Should Consider This Kit
- Patrol Y62 owners who want significantly more power without switching to a turbo setup
- Owners who tow regularly and need stronger low-end torque
- Drivers in high-altitude or mountainous regions where turbo efficiency drops
- Enthusiasts who prefer predictable, linear power delivery
Who Should Think Twice
- Owners not willing to invest in professional installation
- Vehicles with existing engine modifications that may conflict with the supercharger setup
- Owners looking for maximum peak horsepower beyond the 385 PS range — turbo setups can potentially deliver higher top-end numbers, but with trade-offs in drivability
FAQ
How much power does the VT supercharger add to the Patrol Y62 4.0L?Dyno testing shows gains of approximately 106 PS and 106 Nm, bringing the VQ40 from 279 PS / 394 Nm to 385 PS / 500 Nm — roughly a 38% increase in power.
Is there turbo lag with a supercharger?No. A mechanical supercharger is driven directly by the engine's crankshaft via a belt, so boost builds immediately with throttle input. There is no exhaust spool delay like with a turbocharger.
Can I install the VT kit myself?Professional installation is strongly recommended. The kit requires correct belt routing, coolant plumbing, and mechanical expertise.
Does the supercharger work at high altitude?Yes. Because the supercharger is mechanically driven rather than dependent on exhaust gas volume, it maintains consistent boost at elevation — an advantage over turbo setups in mountainous terrain.
Will the VT kit void my factory warranty?Any aftermarket forced induction modification may affect your factory powertrain warranty. Check with your local Nissan dealer and review your warranty terms before installation.
What maintenance does the supercharger require?The VT system has relatively low maintenance requirements compared to turbo conversions. Regular inspection of the drive belt, coolant levels in the intercooler circuit, and standard engine servicing are the key items. The supercharger itself does not require separate oil changes.
Conclusion
The VT-V105 supercharger kit delivers a meaningful upgrade for the Nissan Patrol Y62 4.0L — verified at 385 PS and 500 Nm on a chassis dyno, with the kind of linear, immediate power delivery that suits the Patrol's character as a heavy tourer and tow vehicle. The integrated cooling system and vehicle-specific design keep the installation clean and the operation reliable.
