Hangar 111 K260 Supercharger Kit – Rover K-Series Engines

Durable K-Series Power & Unrivalled Torque

Our “K260” supercharger installation gives the Rover K-Series powered Elise, Exige and 340R a linear torque curve that is a revelation. Incorporating a modified K-Series engine, this kit achieves a smooth-driving 190-260bhp+ power delivery that is perfect for road or track use and can be setup for racing if required. The kit uses Emerald K6 engine management, and is fully installed and testing by experienced Hangar 111 technicians.

Hangar 111 Supercharger Kit for the Rover K-Series to 260bhp and beyond!

Specially developed for the Rover K-Series engined Elise and Exige our Rotrex-based Supercharger kits are available in several forms to cater for both standard cars and those who have already carried out tuning work to their engines.

With years of installing and developing supercharger kits for the Toyota engined Elise, Exige and 2-Eleven behind us, we decided in late 2010 to develop a new supercharger system for the Rover K-Series. The project aim was to create a highly-refined and durable version of the Rover K-Series that would build on the benefits of its lighter weight and small footprint compared to other options on the market. The results are astonishing, achieved without upsetting the balance of the car or the excellent handling dynamics that Lotus intended.

Using a Rotrex C30 centrifugal-type supercharger – specially adapted for Hangar 111 – the system runs between the throttle body and inlet plenum to achieve the best possible part-throttle driveability.

The Rotrex charger unit utilises a totally independent oil system that runs specifically designed oil that greatly reduces friction, lowers charger temperatures – in turn increasing durability. Exceptionally low inlet temperatures are possible thanks to our water-cooled chargecooler system which features the same in-house developed technology from our popular Exige S (Toyota engine) chargecooler kits.

Kit Specifications

We offer a complete turn-key supercharged solution (“K260 – The Works”) that completely overhauls the engine internals and cylinder head before the installation of our specially developed supercharger and chargecooler system. The result is a highly durable powertrain that achieves over 260bhp and 190lb/ft without pushing the car to the high rpm limits that ultimately reduce K-Series engine life. Like the majority of our performance packages, “K260” can be used on the road or track. Please contact us for pricing on this comprehensive fully-installed and set-up solution.

We also offer a component kit with the supercharger and chargecooler. This allows you to build up your own specification. Depending on the engine, cylinder head and exhaust system specification, this kit can achieve between 190bhp and 260bhp+.

The supercharger kit includes:

• Specially designed charger mounting brackets
• Inlet manifold, plenum, and alloy inlet link pipes.
• Alternator bracket, pulleys, and belt tensioners.
• Uprated fuel pump and fuel injectors.
• Custom-made Rotrex centrifugal-type supercharger with oil system.
• Silicone boost hoses, all required gaskets, seals and fasteners.

The racing chargecooler system includes:

• Water-air chargecooler unit.
• Pre-cooler radiator
• Coolant pump, hoses, and electrics.
• All required silicone hoses, connectors and clips for installation.

Additional requirements:

• A low-compression (LC) engine and Emerald K6 ECU will be required.
• Large-bore exhaust manifold and sports catalyst recommended.
• Standard cylinder head ported and polished will achieve max 190bhp.
• VVC cylinder head or big valve conversion will achieve 260bhp+

Due to the wide variations of aftermarket components fitted to the Rover K-Series Elise and Exige, to establish an accurate quotation for your vehicle please contact us and we can take you through the cost based on your existing equipment.
