Protect Your Engine, Unlock Performance

The Toyota GR86 and Subaru BRZ have quickly become favorites among enthusiasts thanks to their balanced chassis, high-revving FA24 engine, and incredible tuning potential. But as with any performance platform, pushing power levels beyond stock introduces new stresses on the engine. One of the least visible—but most dangerous—threats is torsional vibration in the crankshaft.

That’s where the Fluidampr Performance Damper for 2022+ GR86 and BRZ (FA24F/FA24D) comes in. This isn’t just a pulley swap—it’s an engineered solution designed to protect your crankshaft, smooth out your power delivery, and unlock performance that’s often lost to vibration. For anyone planning to tune, boost, or just track their FA24, this upgrade should be high on the priority list.

Understanding Crankshaft Torsional Vibration

To appreciate why a performance damper matters, you need to understand the problem it solves.

• What is torsional vibration? Every time a cylinder fires, it twists the crankshaft slightly. These rapid pulses create harmonic vibrations that travel through the entire crankshaft.

• Why is it bad? Left unchecked, torsional vibration can cause crankshaft fatigue, bearing wear, accessory drive issues, and even catastrophic engine failure.

• Why now? The FA24 engine revs high, sees increased cylinder pressures under boost, and is often pushed harder than the OEM engineers intended—especially when tuned.

The stock crank damper is designed for daily driving, not for sustained high-RPM abuse or modified power levels. That’s why serious builders replace it with a Fluidampr.

How the Fluidampr Works

Unlike traditional harmonic balancers that use a tuned rubber ring, the Fluidampr uses a viscous silicone fluid inside a precision-machined housing.

• Silicone Fluid Technology: The fluid absorbs and dissipates torsional vibration across the entire RPM range—not just at a single frequency.

• Dynamic Control: As RPM rises and vibration changes, the damper adapts in real time.

• Consistent Protection: Works at idle, redline, and everywhere in between.

The result? A smoother-running engine, less stress on the crankshaft and bearings, and more power making it to the wheels instead of being lost to vibration.

Key Features of the Fluidampr for GR86/BRZ

• Stock-Sized Integrated Six-Rib Pulley: Keeps OEM belt fitment and accessory alignment simple.

• Replaceable Crankshaft Hub: Increases serviceability and long-term reliability.

• Corrosion-Resistant Finish: Black zinc coating meets RoHS standards for environmental safety and durability.

• Laser-Engraved Branding: Proudly stamped “Made in the USA” with SFI 18.1 certification.

• Track & Street Approved: Safe for daily driving, legal for racing, and built to handle abuse.

Performance Benefits

Upgrading to a Fluidampr Performance Damper brings tangible benefits for the FA24 platform:

• Reliability at Higher Power: Protects the crankshaft when running tunes, forced induction, or other bolt-ons.

• Smoother Power Delivery: Reduces NVH (noise, vibration, harshness) for a more refined driving experience.

• Increased Engine Longevity: Less stress on bearings and accessories translates into longer engine life.

• Unlocked Horsepower & Torque: Power that was being wasted fighting vibration now makes it to the wheels.

• Track-Proven Safety: With SFI 18.1 certification, it’s approved for motorsport use where safety standards are strict.

Why This Matters for the FA24

The FA24 engine is an excellent base, but like all modern flat-fours, it isn’t immune to vibration-related issues when pushed beyond OEM limits.

• Turbo & Supercharger Builds: Boost dramatically increases torsional forces.

• High-RPM Track Driving: Sustained revs amplify vibration stress.

• Aggressive Tuning: Higher cylinder pressures = more crank twist.

• Longevity Concerns: Even N/A cars see benefits when driven hard over years.

The Fluidampr isn’t just insurance—it’s performance unlocked. It helps ensure your FA24 doesn’t suffer the fate of spun bearings, cracked cranks, or accessory belt failures down the road.

Installation Considerations

Installing the Fluidampr is straightforward for experienced techs, but here’s what to know:

1. Direct Fitment: Uses the stock belt system—no special accessories needed.

2. Professional Install Recommended: Precision torque specs and puller tools required.

3. Tuning Not Required: Unlike some performance upgrades, it doesn’t alter fueling or timing.

4. Serviceability: Hub is replaceable if wear occurs over time.

It’s an install that can be done in an afternoon but has lasting effects for the life of your engine.

Supporting Mods

To maximize the benefits of the Fluidampr, pair it with:

• Upgraded Oil Cooler: Keeps temps under control during track use.

• Performance Radiator: Ensures cooling efficiency.

• ECU Tune: Makes use of the freed-up horsepower and smoother delivery.

• Forced Induction Kits: The more stress you add, the more valuable vibration control becomes.

Together, these upgrades create a robust and reliable FA24 build that can handle serious abuse.

Why Choose Fluidampr?

Fluidampr has been trusted across motorsports for decades, from drag racing to endurance events. Their dampers are:

• Made in the USA: Built with strict quality standards.

• Motorsport-Tested: Proven in environments far harsher than daily driving.

• Backed by Certification: SFI 18.1 approval ensures both safety and reliability.

• Trusted by Builders: A go-to upgrade for professional shops and engine builders worldwide.

When it comes to crankshaft protection, no other aftermarket solution carries the same reputation.

Who Should Run a Fluidampr on Their GR86/BRZ?

• Street Tuners: Running bolt-ons and ECU tunes.

• Track Enthusiasts: Pushing cars in HPDE or time attack events.

• Forced Induction Builders: Turbo or supercharged FA24 engines.

• Reliability-Focused Owners: Anyone who wants their car to last longer under stress.

Even if you’re not chasing 600hp, a Fluidampr adds peace of mind and longevity—critical for cars you plan to keep and enjoy long-term.
