FACTORY FREAK
60–70+ WHP. No Tune. Warranty Intact.
The FAS Factory Freak Package extracts hidden power from the Hellcat platform using bolt-on hardware alone — ported supercharger, billet snout, and FAS Predator lower pulley. Serious gains. Zero ECU modifications. Factory drivability preserved.
What's Included
The same airflow fundamentals FAS applies to higher-tier builds — pulley, intake, ported supercharger, billet snout — delivered as a clean bolt-on installation.
- FAS Predator Lower Pulley Kit
Platform-matched smaller lower pulley increases supercharger drive speed, raising boost pressure across the entire RPM range without ECU intervention.
- High-Performance Cold Air Intake
Larger-diameter intake path reduces inlet restriction and improves charge density — more air in, more power out. Noticeable improvement in intake sound under load.
- FAS Ported Supercharger & Billet Snout
Supercharger case porting and billet snout upgrade improve volumetric efficiency through the blower itself. These are the same core airflow improvements FAS uses in higher-tier builds.
- Installation Labor
Complete bolt-on installation at our Punta Gorda, FL facility. All components fit within factory tolerances — no cutting, no permanent modifications.
- Calibration (TRX only)
TRX builds receive a full live calibration for your specific vehicle and conditions. Trackhawk and Durango SRT builds achieve power targets without ECU modification.
Platform Variants & Pricing
Two Hellcat-platform variants. Same core hardware. Trackhawk and Durango SRT require no tune — TRX includes a full calibration due to the IHI supercharger's requirements.
| Platform | Price | WHP Gain | Tune | Action |
|---|---|---|---|---|
| Trackhawk / Durango SRT | $1,399.99 | 60–70+ WHP | No ECU tune required | Schedule → |
| RAM 1500 TRX | $1,599.00 | 60–70+ WHP | Full calibration included | Schedule → |
Note: Vehicle not included. Installation requires drop-off at our Punta Gorda, FL facility. Factory warranty coverage for bolt-on modifications varies by dealer — confirm with yours before installation. Ready for more power? See FAS800 →
The Build Process
Straightforward bolt-on installation. In and out, numbers confirmed before you leave.
- Coordinate & Drop Off
Contact FAS to confirm platform compatibility and book your installation slot. Drop your vehicle at 6161 Riverside Dr, Punta Gorda, FL 33982.
- Pre-Install Baseline
Your vehicle's condition is documented before any work begins. Platform fit confirmed and build scope finalized.
- Bolt-On Installation
Predator lower pulley, cold air intake, supercharger porting, and billet snout installed by FAS technicians. All work fits within factory tolerances — no cutting, no permanent modifications.
- Verification (TRX: Live Tune Session)
Trackhawk and Durango SRT builds are verified post-install. TRX builds receive a full live calibration while a professional remote tuner adjusts the file in real time.
- Release
Power gains confirmed. Vehicle released with documented baseline-to-result comparison.
The FAS Performance Ladder
Factory Freak hardware carries forward. Moving up tiers costs less when you started with FAS-quality parts already on the car.
Common Questions
- Does this package void my factory warranty?
- No. The Factory Freak package is bolt-on only — no permanent modifications, no ECU changes required for Trackhawk and Durango SRT. The TRX variant includes a tune, which may affect warranty coverage on tune-related components. Consult your dealer for specifics on your vehicle.
- Is this a parts kit or an installation service?
- This is a full installation service. You bring your vehicle to our Punta Gorda, FL shop and we handle everything. You leave with parts installed and verified.
- Why does the TRX variant cost more and include a tune?
- The TRX uses an IHI supercharger with slightly different airflow characteristics than the Trackhawk/Durango setup. To hit the same power target reliably and safely, the TRX variant includes a full calibration. The Trackhawk and Durango SRT can achieve 60–70+ WHP gains from the bolt-ons alone.
- How does this compare to the FAS800?
- The Factory Freak is a warranty-safe, no-tune entry package targeting 60–70+ WHP gains. The FAS800 is a full performance build targeting 800 WHP and requires ECU unlock and live calibration. If you want maximum power or plan to track the vehicle, the FAS800 is the right path. If you want meaningful gains while keeping the factory tune, start here.
- Can I upgrade to a higher FAS tier later?
- Yes. The Factory Freak components — ported supercharger, billet snout, intake — carry forward as part of higher-tier builds. Moving up to FAS800 or beyond builds on this foundation rather than starting over.
