24x Racing High-Flow CNC Race Head
300 CFM Certified – Engineered for Serious SRT-4 Power
Built for Power Levels Where Airflow Becomes the Limiting Factor
At moderate power levels, most CNC programs work.
At 800+ WHP and high RPM, airflow design separates average builds from serious ones.
This CNC head program was developed, tested, and validated on our own 8-second drag car — engineered specifically for aggressive turbo setups, high boost, and sustained high RPM abuse.
This is not a mild street clean-up port.
This is a high-flow race program built for serious horsepower.
Proven Under Real Abuse
This design has been tested for over 200 passes on our 8-second SRT-4 drag car — all while maintaining consistent performance and durability.
Not dyno theory.
Not flow numbers without proof.
Real passes. Real abuse. Real results.
300 CFM Certified – The Benchmark
After in-depth analysis and flow bench testing of multiple competing Neon SRT-4 heads, we confirmed the difference.
We are the only provider offering a Neon SRT-4 head that achieves a certified 300 CFM at 0.480" lift.
Every shipped head includes:
✔ Official flow bench chart
✔ Certified 300 CFM documentation
✔ Complete transparency on airflow performance
This is measurable performance — not marketing claims.
🔧 Basic Race Package – What’s Included
Every head goes through a complete race-prep process before it leaves.
Base Package Inclusions:
➡️ Full Head Inspection
Crack inspection and dimensional verification before machining begins.
➡️ Hot Tank Cleaning + Precision Surfacing
Proper deck preparation to ensure head gasket integrity under high boost.
➡️ Full CNC High-Flow Race Port
Aggressive intake and exhaust port program engineered for maximum airflow.
➡️ CNC Chamber Machining
Combustion chamber optimization for improved airflow efficiency and combustion stability.
➡️ Brand New Manganese Bronze Valve Guides
Upgraded for durability under high heat and sustained RPM abuse.
➡️ Precision CNC Valve Job
Performance multi-angle valve job
+1mm Intake
+2mm Exhaust
Designed to increase flow capacity and improve high-lift efficiency.
Why This Head Is Different
Many CNC programs prioritize street drivability and conservative flow targets.
This program prioritizes:
• Maximum airflow volume
• High-RPM breathing efficiency
• Big turbo compatibility
• Balanced cylinder-to-cylinder flow
• Top-end horsepower capability
When boost and RPM rise, factory castings become the restriction.
This removes that restriction completely.
Power Range Recommendations
Primarily Engineered For:
✔ 800+ WHP builds
✔ Big turbo applications
✔ High boost + high RPM setups
✔ Drag racing & track builds
✔ Competitive performance cars
Compatible With:
✔ Aggressive street setups
✔ Built motor turbo builds
✔ Upgraded cam and valvetrain packages
While it can be used under 800 WHP, this CNC program was engineered specifically to support high horsepower drag and track applications.
Performance Impact
On properly supported builds, this head typically results in:
• Stronger top-end horsepower
• Improved high-RPM efficiency
• Increased turbo airflow potential
• Better volumetric efficiency
• More stable power at high boost
Airflow is the foundation.
This head maximizes it.
Comparison vs Typical CNC Programs
| Feature | Stock Head | Standard CNC Program | 24x Racing High-Flow CNC |
|---|---|---|---|
| Certified 300 CFM @ .480" | ✖ | None known | ✔ |
| Flow Chart Included | ✖ | Rarely | ✔ |
| Designed for 800+ WHP | ✖ | Limited | ✔ |
| Drag-Tested (200+ Passes) | ✖ | Unknown | ✔ |
| +1 / +2 Valve Configuration | ✖ | Not Standard | ✔ |
| CNC Chamber Optimization | ✖ | Sometimes | ✔ |
This is not the cheapest option on the market.
It is the most airflow-capable.
Designed for Serious Builds
Best paired with:
✔ Big turbo systems
✔ Built bottom end
✔ Upgraded valvetrain
✔ Performance camshafts
✔ Proper engine management
Airflow must match the intent of the build.
⚔ Power Rewards the Prepared
You invested in the turbo.
You built the bottom end.
You upgraded the transmission.
Leaving the head restrictive at serious power levels makes no sense.
At 800+ WHP, airflow is not optional.
This program has proven itself — over 200 passes, certified 300 CFM, and race-validated durability.
If you're building real power, this is the foundation.
Secure your CNC head program and eliminate the restriction before it limits your build.
