However, for enthusiasts who crave more—more thrust, more urgency, more excitement—forced induction is the natural next step. Among the aftermarket options available, the ACRE Supercharger Kit has emerged as a compelling choice for those seeking a well-engineered, reliable boost solution.

This article provides a thorough performance review of the ACRE Supercharger 370Z Kit, supported by real-world user data and technical analysis. We will also deliver detailed installation guidance to help you navigate the process with confidence. Whether you are a seasoned DIY mechanic or considering a professional install, this guide will give you the insights needed to make an informed decision.

Overview of the ACRE Supercharger 370Z Kit

The ACRE Supercharger Kit represents a carefully engineered forced-induction system designed specifically for the Nissan 370Z (model years 2009–2020). Unlike generic universal supercharger setups that require extensive fabrication, this kit is purpose-built for the VQ37VHR engine, ensuring proper fitment, reliable performance, and straightforward installation.

At the heart of the kit is a positive-displacement supercharger unit, which delivers immediate boost pressure across the entire RPM range. This is a significant advantage over centrifugal superchargers, which tend to build boost progressively at higher engine speeds. The positive-displacement design gives the 370Z a notably punchy, responsive feel from idle to redline — exactly what many drivers want for street driving and canyon carving.

The kit includes a complete billet aluminum intake manifold with integrated intercooler cores, a high-flow air filter assembly, upgraded fuel injectors, a boost-referenced fuel pressure regulator, and a pre-programmed ECU tune. ACRE also supplies all necessary hardware, gaskets, and hoses, which dramatically reduces the guesswork during installation.

Key technical specifications:

  • Supercharger type: Twin-screw positive displacement
  • Maximum boost pressure: 7-8 PSI (pump gas configuration)
  • Intercooling: Integrated air-to-water intercooler
  • Fuel system: 550cc injectors with boost-referenced regulator
  • Included engine management: ECU reflash via Ecutek or equivalent
  • Estimated power output: 430-470 wheel horsepower (depending on supporting mods)

ACRE positions this kit as a "street-friendly" upgrade that does not require internal engine modifications. The boost levels are conservative enough to maintain reliability on stock internals while still delivering a transformation in driving character.

Performance Review: Dyno Results and Real-World Driving

Measured Horsepower and Torque Gains

The most compelling reason to consider the ACRE Supercharger Kit is the measurable increase in power. Independent dyno testing conducted by multiple tuning shops has consistently shown gains that dramatically alter the 370Z's performance envelope.

Typical dyno results (at the wheels):

  • Stock Nissan 370Z: 270-285 whp / 240-255 lb-ft wtq
  • ACRE Supercharger Kit (pump gas, 7-8 PSI): 420-460 whp / 360-390 lb-ft wtq
  • With additional bolt-ons (exhaust, intake, headers): 460-490 whp / 390-410 lb-ft wtq

These figures represent an increase of roughly 150-180 wheel horsepower over stock — a substantial gain that places the 370Z firmly in the territory of much more expensive performance cars. The torque curve is particularly impressive: where the stock engine feels somewhat flat below 4,000 RPM, the supercharged car delivers strong, linear torque from as low as 2,500 RPM, making everyday driving far more enjoyable.

Acceleration and Quarter-Mile Performance

With the ACRE kit installed, the 370Z's acceleration figures improve dramatically. On street tires, drivers report 0-60 mph times dropping from the stock 5.0-5.2 second range to approximately 3.9-4.2 seconds, depending on traction conditions and driver skill. The quarter-mile, which typically runs in the mid-13-second range for a stock 370Z, can drop into the 11.9-12.3 second range at trap speeds of 117-122 mph.

These numbers put the ACRE-equipped 370Z in direct competition with modern muscle cars like the Dodge Challenger Scat Pack and Chevrolet Camaro SS, while retaining the lighter weight and sharper handling that make the Z-car special.

Driving Character and Daily Usability

One of the standout qualities of the ACRE twin-screw supercharger is its drivability. Unlike some aggressive forced-induction setups that deliver sudden, peaky boost, the ACRE system provides a smooth, building surge that feels natural and predictable. The integrated air-to-water intercooler helps maintain consistent intake air temperatures, which is critical for both performance and engine longevity during extended spirited driving sessions.

In normal commuting, the car remains perfectly tractable. The ECU tune includes refined throttle mapping and fuel delivery strategies that prevent the jerky on-off response common with poorly calibrated supercharger kits. When driven gently, the car feels like a well-mannered, slightly more powerful version of the stock 370Z. When the throttle is opened fully, the supercharger whine builds audibly, and the car pulls with an urgency that is genuinely addictive.

Heat management is also noteworthy. The VQ37VHR engine is known for generating high under-hood temperatures, which can become problematic with turbocharger setups. The ACRE supercharger, with its integrated intercooler and thoughtful heat shielding, tends to run cooler than many turbo alternatives, contributing to consistent performance even on track days or during aggressive canyon driving.

Reliability Considerations

With any forced induction system, reliability is a primary concern. The ACRE kit is designed to operate within the safety margins of the stock VQ37VHR engine. At 7-8 PSI of boost, the engine's cast pistons and forged connecting rods are well within their design limits, provided the engine is in good health before installation. ACRE recommends performing a compression test and leak-down test prior to installation to verify the engine's condition.

Oil and cooling system upgrades are strongly recommended. Many experienced owners combine the ACRE kit with an oil cooler, a higher-capacity radiator, and a differential cooler for track use. Regular oil changes with high-quality synthetic oil are even more critical with forced induction. MotorTrend's analysis of supercharger versus turbo reliability reinforces that well-designed positive-displacement systems tend to place less thermal stress on engines than their turbo counterparts, making them a solid choice for daily-driven performance cars.

Installation Tips: A Step-by-Step Guide for Success

Installing the ACRE Supercharger Kit is a significant undertaking that requires mechanical competence, patience, and attention to detail. While ACRE provides a comprehensive instruction manual, experienced installers have developed best practices that can save time and prevent common pitfalls.

Preparation and Tooling

Before beginning, ensure you have the following tools and supplies on hand:

  • Comprehensive metric socket and wrench set (8mm through 24mm)
  • Torque wrench (capable of 10-80 ft-lb range)
  • Gasket scraper and brake cleaner for surface preparation
  • Thread locker (medium strength) for critical fasteners
  • Coolant vacuum fill tool (to prevent air pockets)
  • Fuel pressure gauge for system testing
  • Scan tool or Ecutek cable for ECU flashing

Plan for 12-20 hours of labor for a first-time installation performed by an experienced DIY enthusiast. Professional shops typically complete the installation in 8-12 hours.

Step 1: Disconnect the Battery and Drain Fluids

Begin by disconnecting the negative battery terminal. Drain the engine coolant at the radiator petcock and remove the radiator hoses. The intake manifold must be removed to access the lower intake ports, which requires clearing the coolant system. Be prepared with fresh Nissan-spec coolant for reassembly.

Step 2: Remove the Factory Intake Manifold

The stock intake manifold is held in place by 10mm and 12mm bolts. Access to the rear bolts can be tight — using a combination of extensions and swivel joints will make this significantly easier. Label the wiring harness connectors as you disconnect them, particularly the throttle body and manifold absolute pressure (MAP) sensor connections. Take photographs before disassembly to serve as a reference during reassembly.

Pro tip: While the intake manifold is removed, inspect the intake ports for carbon buildup. The VQ37VHR engine is prone to carbon deposits on the intake valves, and this is an excellent opportunity to perform a walnut blasting cleaning if needed.

Step 3: Install the ACRE Supercharger Manifold and Intercooler Core

The ACRE kit includes a new billet aluminum manifold that incorporates the supercharger mounting flange and the intercooler cores. Position the manifold with new gaskets supplied in the kit, and torque the mounting bolts in a crisscross pattern to the manufacturer's specifications (typically 15-18 ft-lb for the manifold bolts).

The water-to-air intercooler system requires connecting coolant hoses to the electric water pump and heat exchanger. Ensure the hose routing does not contact sharp edges or moving components. Use the supplied hose clamps and verify that all connections are secure before adding coolant.

Step 4: Mount the Supercharger Unit

The supercharger unit bolts directly to the new intake manifold. Apply a thin layer of the supplied assembly lubricant to the rotor pack before installation. The drive pulley alignment is critical — verify that the supercharger pulley aligns perfectly with the crank pulley to prevent belt wear and noise. ACRE includes shims for fine-tuning alignment if necessary.

Install the drive belt following the routing diagram in the manual. Manually rotate the engine at the crankshaft bolt to verify that the belt runs true and there is no interference with any components.

Step 5: Fuel System Modifications

ACRE supplies 550cc fuel injectors that replace the stock units. Carefully remove the old injectors, lubricate the new injector O-rings with clean engine oil, and press them into the fuel rails by hand — do not use tools that could damage the injector bodies. Install the boost-referenced fuel pressure regulator and connect the vacuum reference line to the intake manifold.

Critical check: After assembly, pressurize the fuel system by cycling the ignition on and off several times (without starting the engine). Inspect every fuel connection for leaks using a clean paper towel. Any sign of fuel leakage must be addressed before proceeding.

Step 6: ECU Calibration

The ACRE kit includes a pre-programmed ECU tune, typically delivered via the Ecutek platform. Flashing the ECU requires a laptop with the Ecutek software and the supplied cable. The process takes approximately 20 minutes. Do not start the engine until the flash is complete and verified.

After flashing, perform an idle relearn procedure as described in the manual. This typically involves warming the engine to operating temperature, turning the ignition off, and restarting after a 30-second pause.

Step 7: Initial Start-Up and Testing

Before starting the engine, verify the following:

  • All electrical connections are secure
  • All coolant hoses are connected and the system is filled
  • The drive belt is properly tensioned
  • The oil level is correct
  • No tools or debris remain in the engine bay

Start the engine and allow it to idle for 15-20 minutes while monitoring coolant temperature, oil pressure, and boost pressure (via the OBD2 port). Check for any unusual noises, vibration, or fluid leaks. The supercharger should produce a subtle whine that increases with engine RPM — a grinding or knocking sound indicates a problem that must be investigated immediately.

EngineLabs offers an excellent technical guide on supercharger installation best practices that aligns closely with the procedures required for this kit.

Common Challenges and Solutions

Space Constraints in the Engine Bay

The 370Z's engine bay is compact, making access to the rear of the intake manifold and the firewall-side components challenging. This is the area where most installers lose time. Using flexible ratchet extensions, universal joints, and wobble sockets can save hours of frustration. Removing the strut tower brace and, in some cases, loosening the engine mounts to tilt the powertrain forward may provide the extra clearance needed for the rear manifold bolts.

Electrical Connection Difficulties

The throttle body and MAP sensor connectors on the VQ37VHR are fragile and difficult to disconnect if they have not been touched in years. Use a small pick tool to release the locking tabs before pulling. If a connector breaks, replacement pigtails are available through Nissan parts suppliers. NissanSpecs maintains a comprehensive VQ37VHR engine guide that covers connector part numbers and wiring diagrams.

Supercharger Belt Tension and Alignment

Belt noise is the most common post-installation complaint. This is almost always due to pulley misalignment or incorrect belt tension. Verify alignment using a straightedge across all pulleys. If the belt squeals on initial start-up, re-check the tension — the belt should deflect approximately 1/2 inch under moderate thumb pressure at the midpoint of the longest span.

Calibration Issues

The pre-programmed ECU tune provided by ACRE is designed for a standard vehicle. If your 370Z has modifications such as aftermarket exhaust headers, high-flow catalytic converters, or a larger throttle body, the tune may require adjustment. In these cases, professional dyno tuning by a certified Ecutek tuner is highly recommended. A proper tune not only maximizes power but also ensures safe air-fuel ratios and ignition timing.

Maintenance and Long-Term Care

With the ACRE Supercharger Kit installed, maintenance intervals for certain items change. Pay attention to the following:

  • Oil changes: Every 3,000-4,000 miles with high-quality synthetic 5W-30. The supercharger places additional load on the engine, making frequent oil changes essential for bearing and valvetrain longevity.
  • Supercharger oil: The twin-screw unit requires its own oil supply. Check the oil level every 10,000 miles and change it every 30,000 miles.
  • Drive belt: Inspect for cracking and glazing every 10,000 miles. Replace at 30,000 miles or sooner if signs of wear appear.
  • Intercooler coolant: Change every two years to maintain thermal efficiency and prevent corrosion in the water-to-air system.
  • Spark plugs: The increased cylinder pressure from forced induction accelerates spark plug wear. Replace with colder-range plugs (one step colder than stock) every 20,000 miles.

Cost and Value Analysis

The ACRE Supercharger Kit is priced competitively within the forced induction market for the 370Z. Typical costs break down as follows:

  • Kit cost: $5,500 - $6,200 (depending on retailer and included options)
  • Professional installation: $1,200 - $2,000
  • Dyno tuning (if needed): $600 - $900
  • Supporting modifications (oil cooler, radiator, clutch): $1,000 - $3,000

This places the total investment between $7,000 and $12,000, depending on the scope of supporting upgrades. For that cost, the owner gains 150-200 wheel horsepower, transforming the 370Z's performance to a level that rivals cars costing significantly more. Car and Driver's long-term review of the 370Z Nismo highlights that even the factory's own performance variant leaves room for more power — a gap that the ACRE kit fills convincingly.

Resale value considerations are mixed. A professionally installed supercharger kit with supporting documentation and tune records can actually enhance the car's appeal to informed buyers. However, a poorly executed installation or the removal of the kit before sale may complicate resale. Enthusiast forums suggest that well-maintained supercharged 370Zs with the ACRE kit command a premium of $3,000-$5,000 over comparable naturally aspirated cars in private sales.
