Tuning for Peak Performance: Achieving 650-700 Hp with Holset Hx35 Turbo vs Paxton Novi 1200 Supercharger
Tuning a vehicle for peak performance is an exciting challenge for automotive enthusiasts. In this article, we will explore two popular options for achieving 650-700 horsepower: the Holset HX35 turbocharger and the Paxton Novi 1200 supercharger. Both systems offer unique advantages and characteristics that cater to different tuning preferences and driving styles.
Understanding Turbochargers and Superchargers
Before diving into the specifics of the Holset HX35 and Paxton Novi 1200, it’s essential to understand the fundamental differences between turbochargers and superchargers.
- Turbochargers: Utilize exhaust gases to spin a turbine, which compresses intake air.
- Superchargers: Driven directly by the engine’s crankshaft, providing immediate power boost.
Advantages of Turbocharging
Turbocharging has become increasingly popular due to its efficiency and power potential. Here are some key advantages:
- Higher power output per liter of engine displacement.
- Improved fuel efficiency compared to naturally aspirated engines.
- Less weight added to the vehicle compared to supercharger systems.
Advantages of Supercharging
Superchargers also present unique benefits that can enhance vehicle performance:
- Immediate power delivery with no lag, providing instant throttle response.
- Simpler installation and tuning process compared to turbo systems.
- Consistent power throughout the RPM range.
Holset HX35 Turbocharger Overview
The Holset HX35 turbocharger is a popular choice among tuners looking to achieve significant horsepower gains. It is known for its durability and ability to handle high boost levels.
Specifications
- Compressor wheel size: 60mm
- Max boost pressure: 30 PSI
- Suitable for engines up to 6.0L
Tuning Potential
With proper tuning, the Holset HX35 can efficiently produce between 650 and 700 horsepower. Key aspects of tuning include:
- Fuel system upgrades to support increased fuel flow.
- ECU remapping to optimize air-fuel ratios.

Paxton Novi 1200 Supercharger Overview
The Paxton Novi 1200 supercharger is a centrifugal supercharger designed for high performance. It offers a different approach to achieving power gains compared to the Holset HX35.
Specifications
- Max boost pressure: 12 PSI
- Suitable for engines ranging from 4.6L to 6.0L
- Power gains of 50-75% over naturally aspirated engines.
Tuning Potential
The Paxton Novi 1200 can also achieve 650 to 700 horsepower with the right tuning. Important tuning considerations include:
- Upgraded fuel injectors for increased fuel delivery.
- Custom tuning for optimal performance and reliability.
- Cooling system enhancements to manage increased heat levels.
Comparative Analysis: Holset HX35 vs. Paxton Novi 1200
When choosing between the Holset HX35 turbocharger and the Paxton Novi 1200 supercharger, several factors come into play. Here’s a comparative analysis:
- Power Delivery: Turbochargers often exhibit turbo lag, while superchargers provide instant power.
- Tuning Complexity: Turbo systems may require more complex tuning than supercharger setups.
- Heat Management: Turbochargers can create more heat, necessitating better cooling solutions.
Conclusion
Both the Holset HX35 turbocharger and the Paxton Novi 1200 supercharger are excellent choices for achieving 650-700 horsepower. The decision ultimately comes down to personal preferences regarding power delivery, tuning complexity, and overall driving experience. Understanding the strengths and weaknesses of each system will help enthusiasts make informed decisions for their performance builds.
