In the world of motorsport and high-performance vehicles, the significance of an efficient exhaust system cannot be overstated. It plays a vital role not only in managing exhaust gases but also in enhancing engine performance. One standout product that embodies this philosophy is the Alunox LOTUS FEDERL and HCI Esprit Turbo 321 Stainless Steel Manifold/Rear System. This blog post will explore the features, benefits, and craftsmanship that make this manifold system a must-have for Lotus Esprit enthusiasts.
A Brief History of Alunox
Alunox is a well-established name in the engineering sector, particularly known for its contributions to the motorsport industry. The company has earned a reputation for supplying tailor-made high-end exhaust systems crafted from exotic materials such as Inconel, titanium, and 321 Stainless Steel. Their expertise extends beyond exhaust systems; they also provide BAC cars with lightweight components for their current production model, the Mono.
The company’s journey began with a commitment to innovation and quality. By focusing on creating bespoke solutions tailored to the unique needs of performance vehicles, Alunox has positioned itself as a trusted partner among car manufacturers and enthusiasts alike.
The Need for Upgraded Manifolds
The Lotus Esprit, particularly the four-cylinder variant, has a storied history in the automotive world. However, it has faced challenges regarding its original cast manifold, which is known for its high failure rate and relatively short life cycle. Recognising this issue, Alunox set out to redesign the manifold, delivering a direct replacement that improves durability and performance.
The Alunox manifold is constructed from 321 Stainless Steel, a material renowned for its strength and resistance to thermal stress—an essential feature for turbo applications. By addressing the shortcomings of the original design, Alunox provides a solution that enhances the longevity and reliability of this iconic vehicle.
Key Features of the Alunox Manifold
Fracture-Proof Construction
One of the standout features of the Alunox LOTUS FEDERL and HCI Esprit Turbo manifold is its use of 321 Stainless Steel. This particular alloy is specifically chosen for its excellent mechanical properties at elevated temperatures, making it ideal for turbocharged applications. The result is a manifold that can withstand the rigours of high-performance driving without succumbing to fractures or failures.
Precision Engineering
The flanges of the manifold are meticulously cut from stainless steel and CNC machined to ensure an accurate fit. This precision is crucial for maintaining optimal exhaust flow and minimising leaks, which can adversely affect performance. Alunox employs high-precision dedicated jigs throughout the manufacturing process to ensure every component is consistent and accurate.
Advanced Joint Design
The collectors in the Alunox manifold utilise Burns double slip joints. These joints allow for movement during the heat cycle, accommodating thermal expansion without compromising the integrity of the connection. Additionally, a pivoting brace is mounted at the back of the head to further enhance stability. This design helps protect against shock loading, ensuring that the manifold remains securely attached even under extreme conditions.
TIG Welding Excellence
Alunox employs TIG welding throughout the assembly of all components. This method ensures optimum quality by providing a smooth inner surface that maximises flow while maintaining high corrosion resistance. The complete fusion achieved through this technique results in a durable product that can withstand harsh environments.
Mandrel Bending for Flow Efficiency
To achieve consistent diameters and maximise flow, all tubes are bent using a mandrel. This process helps maintain the integrity of the pipes and ensures that exhaust gases can escape efficiently, leading to improved overall engine performance. The downpipes are all equal length mandrel bent tubes creating the pulse tuning effect and greatly enhancing scavenging over the original non-equal length log cast configuration. In addition to this, flow is maximised due to the smooth internal surfaces unlike the rough flaking internal bores of the original.
The Turbosmart Compgate 40
Included in the manifold kit is a Turbosmart Compgate 40 wastegate, mounted on V-Bands. This component plays a crucial role in managing boost pressure and ensuring that the engine operates within its optimal range. The wastegate's design allows for precise control over boost levels, contributing to both performance gains and engine longevity.
By integrating high-quality components like the Turbosmart wastegate into their manifold system, Alunox ensures that users receive a comprehensive solution designed for maximum performance.
