What Makes Demon-Ported Superchargers Superior?
The Demon-ported Hellcat supercharger represents the pinnacle of forced induction technology for HEMI engines. Unlike stock superchargers, our precision-porting process:
- Increases airflow capacity by 18-22% compared to factory units
- Reduces intake air temperatures (IATs) for consistent power output
- Optimizes rotor pack efficiency through computational fluid dynamics
- Maintains OEM reliability while delivering race-ready performance
Documented Performance Improvements
Horsepower Increase
+80-120 WHP (dyno-proven on 93 octane)
Torque Gain
+90-110 lb-ft at the wheels
Boost Response
15% faster spool time vs. stock
The Precision Parts Hub Engineering Difference
Our supercharger porting process isn’t just about removing material – it’s about intelligent airflow optimization:
Stage 1: Computational Analysis
Using advanced CFD software, we map airflow patterns to identify restriction points while maintaining structural integrity.
Stage 2: Precision Porting
CNC-guided porting enlarges intake pathways while creating venturi-effect transitions for laminar flow.
Stage 3: Surface Optimization
Mirror-polished interiors reduce turbulence and heat retention for maximum efficiency.
Compatibility & Installation
Our Demon-ported superchargers are direct replacements for:
- Dodge Challenger SRT Hellcat (2015-present)
- Dodge Charger SRT Hellcat (2015-present)
- Jeep Grand Cherokee Trackhawk (2018-present)
- Durango SRT Hellcat (2021-present)
Installation Requirements
While designed as bolt-on upgrades, we recommend:
- Professional installation by certified technicians
- Complementary fuel system upgrades for maximum gains
- Aftermarket heat exchanger for sustained performance
- ECU tuning to optimize air/fuel ratios
Real-World Performance Testing
Independent testing at Bandimere Speedway showed:
- 0.3-0.5 second reduction in 1/4 mile times
- 7-9 mph trap speed increases
- Consistent IATs 25°F lower than stock at WOT
These gains were achieved without compromising daily drivability or factory warranty coverage (when installed by ASE-certified technicians).
Frequently Asked Questions
Will porting my supercharger void my warranty?
Magnuson-Moss Warranty Act protects modified vehicles as long as the modification isn’t directly responsible for a failure. Many dealers offer performance packages that include our ported superchargers.
How does porting compare to supercharger replacement?
Porting delivers 80% of the gains of a full supercharger upgrade at 30% of the cost, making it the most cost-effective power adder for Hellcat engines.
What supporting mods are recommended?
For optimal results, pair with:
- High-flow air intake system
- Upgraded heat exchanger
- 92+ octane fuel or ethanol blends
- Professional dyno tuning
