Introduction
Mazda’s Skyactiv-G 2.0L and 2.5L naturally aspirated engines are widely fitted on classic models including Mazda3 Axela, Mazda6 Atenza, CX-3, CX-30, CX-5 and CX-8. These power units are praised for high compression ratio, excellent fuel economy and smooth daily driving temperament, yet they have an obvious pain point for power lovers: insufficient low-end torque, weak overtaking ability at high speed, and power attenuation under full passenger and heavy luggage load.
To perfectly solve the power bottleneck of Mazda Skyactiv-G NA engines, ANROT officially launches the VT Twin-Screw Positive Displacement Supercharger Complete Kit, a mature forced induction upgrade that balances explosive power output, original vehicle reliability and daily driving comfort.
Working Principle of VT Twin-Screw Mechanical Supercharger
Different from exhaust-driven turbochargers with obvious lag and high-rev-focused centrifugal superchargers, the VT twin-screw supercharger adopts crankshaft synchronous belt direct drive structure. It operates synchronously once the engine is ignited.
Two precision helical screw rotors mesh and rotate oppositely, trapping air inside the cavity and completing internal compression inside the supercharger housing. High-density cold compressed air is continuously delivered into combustion chambers, realizing instant boost pressure from idle speed, zero turbo lag and fully linear power delivery. The strong low-RPM torque output brings large-displacement naturally aspirated driving texture, which is far more suitable for daily urban commuting, highway acceleration and mountain road climbing.
Core Power Upgrade Parameters
- Stock power: Original Skyactiv-G 2.0L / 2.5L factory horsepower and torque
- After VT supercharger upgrade: Stable 40% overall power and torque improvement
- Safe boost setting: Conservative 0.4 bar low-pressure calibration, completely within the load tolerance of Mazda original engine internal components, no damage to crankshaft, piston and connecting rod
- Tuning advantage: Custom road-tested ECU program keeps stable idle speed, no dashboard fault codes, compatible with original i-Stop auto start-stop system
Full Package Configuration & Hardware Quality Advantages
Our one-stop VT twin-screw supercharger kit contains all mounting accessories, no extra parts need to be purchased separately:
- VT twin-screw supercharger main body with high-precision meshing screw rotors, low vibration, low heat generation and ultra-long service life; available in matte black and racing red two colors for option
- CNC integrated die-cast thickened steel vehicle-specific mounting brackets, anti-deformation under long-term bumpy road conditions, perfect fit for Mazda engine compartment layout;
- Independent water-to-air intercooler cooling system + full set of high-temperature resistant silicone pipelines, effectively lowering intake temperature and eliminating power heat decay during continuous heavy-load climbing or high-speed cruising;
- Professional pressure relief valve, reinforced drive belt, tensioner pulley, all bolts, gaskets, wiring harness and small fitting accessories;
- Dedicated optimized ECU calibration program, reasonably adjusted fuel injection volume and ignition advance angle, retaining original fuel economy performance as much as possible.
Highlighted Product Advantages
1. 100% Bolt-On Non-Destructive Reversible Installation
All brackets and pipelines are tailor-made according to the original vehicle hole positions, fixed directly by bolts only. No body cutting, no welding, no wire breaking, no drilling. The whole modification is fully reversible, and the vehicle can be completely restored to factory stock condition at any time without residual modification traces. Professional repair shops can finish the whole installation within 6 working hours.
2. Excellent Daily & All-Road Driving Experience
- Urban start & low-speed driving: Instant torque output eliminates the sluggish feeling of original NA engine slow power response;
- Highway overtaking: Powerful mid-range acceleration, safer and more confident for high-speed road overtake;
- Mountain climbing & full-load travel: Abundant torque reserve solves the fatigue of frequent downshifting when carrying full passengers and luggage;
- NVH performance: Low mechanical operating noise, no harsh screaming, perfectly retains Mazda’s original quiet interior comfort.
3. Outstanding Durability & Global Warranty
With regular standard maintenance, the VT twin-screw supercharger assembly can achieve up to 300,000 kilometers service life. The complete kit is covered by 2 years worldwide official warranty, covering non-artificial damage failure of core components, allowing global Mazda owners to purchase and use with full confidence.
4. Good Compatibility for Multiple Mazda Models
Widely compatible with Mazda models equipped with Skyactiv-G 2.0L / 2.5L gasoline naturally aspirated engines:
Mazda3 Axela, Mazda6 Atenza, CX-3, CX-30, CX-5, CX-8 petrol versions.
Note: diesel models are not available for our supercharger upgrade.
