This Boyesen cooling upgrade helps improve coolant flow and temperature control for more consistent performance in demanding riding conditions.

Internal engine heat, although needed for horsepower, is also extremely destructive to your engine if it is not managed properly. Internal-combustion engines burn fuel hotter than the melting temperature of engine materials. When an engine is operating out-of-balance with its cooling system's capacity, the internal temperatures often rise to levels that cause damage to the cylinder, piston, and valve-train components. If these parts become heated over the optimal operating upper limit range, component damage will begin to occur. Reduced to its common reasons for being essential in an internal combustion engine, cooling system efficiency can have a dramatic influence on the longevity of the internal working components of your bike's engine. These include the reduction of thermal stresses and strains caused by pre-ignition and detonation (particularly the latter), distorted cylinder bores, potential damage to pistons and rings, and damaged valve-train components.

HOW EXCESSIVE ENGINE HEAT IMPACTS EFI SYSTEMS
Most people know that when your engine runs hot, it will make less horsepower – but what causes this to occur? In order for optimal horsepower to be generated, your machine’s EFI system is required to deliver a precise mixture of air/fuel after processing data from sensors located in the engine. This continual process ensures that optimal engine performance is consistent. Taking a closer look into this process reveals that EFI equipped engines use ECT (Engine Coolant Temperature Sensing) to deliver moment-to-moment coolant/engine temperature data to the ECU. The Engine Control Unit (ECU) uses this feedback to continually factor your machine’s engine temperature and make on-the-fly adjustments to ignition timing, and air/fuel mixture (as a percentage of +/-) from the pre-determined, optimal air/fuel mapping.

When the ECT sensor detects excessive engine heat and transmits this data to the ECU, the ECU automatically retards timing, and richens the air/fuel mixture. This is done in order to bring the operating temperature of the engine back down to its optimal operating temperature. It is a pre-programmed fail-safe condition and it is the way your bike has been designed to protect itself from heat-related engine failure. When the ECU adjusts into fail-safe mode this has a direct impact on how much horsepower your engine is ALLOWED to produce – this is largely based on the temperature of your machine’s engine at any given time and is why controlling engine temperature is emerging as one of the most important aspects of engine tuning. By reducing core engine temperatures your machine’s power characteristics will be optimised and your engine will not be forced by the ECU to reduce its horsepower output in order to protect itself from overheating. 

HYPERFLOW INTEGRATION ADVANTAGE: ANTI-CAVITATION PERFORMANCE
What is HFI? Otherwise known as Hyperflow Integration, HFI represents Boyesen's holistic approach to improving the efficiency and flow rates of your bike's water pump systems. Like any project at Boyesen, HFI is an engineering design process that is rooted in researched and tested performance. It is the driving force behind why the Supercooler works so well. HFI is the backbone of each Supercooler's final design and it is based on the process of correcting the in-efficiencies and production-based limitations found in the design of stock waterpump systems. For each Supercooler made, Boyesen Engineers apply ongoing research and development processes that yield the greatest increases in cooling performance for each make/model/year of machine in the following areas: Inlet Diameter Capacity Hydro-dynamically Optimised Interior Surface Modelling Hydro-dynamically Optimised Impeller Design and Function. What's the result of the HFI design process? Superior fluid flow rates, increased hydrodynamic efficiency, and superior heat management capability yields the best performing water pump system that you can buy. Simply stated, HFI innovation has been recognised worldwide by factory race teams as the technological benchmark in bolt-on engine heat-reduction performance.

    SPECIAL ORDERS

    In order for us to be able to offer the entire range of some products, we have a special order in process. Once you place your order, we will order your items in from our suppliers. This allows you to have more freedom in choice of colour, style, upgrades etc.

    Processing time can vary - some items we will have within a few days, whereas some items are ordered in from the United States of America or Europe, and therefore require an extra few weeks to account for shipping time and in some cases, manufacturing time. You will receive an email confirmation when your order has been placed and you will receive status updates on your order as it progresses.

    If you have any questions or concerns or would like a rough ETA on order delivery times or stock levels, please get in touch with our customer service team and they will be able to assist you: support@motohouse.com.au or (07) 5681 1505.

    ITEMS FROM USA

    We place stock orders from the USA every week - this includes items from Luxon. We try our best to ensure all items are in stock but if not - please allow an extra 1-2 weeks for your order to be processed. 

    SHIPPING

    We offer free standard shipping on all items (excluding bulky items) over $20 within Australia and over $50 to New Zealand. All other internaitonal destinations will be invoiced separately. View our shipping policy here
