Eventuri Carbon Turbo Tube for FK8 Honda Civic Type R

Eventuri Carbon Turbo Tube for FK8 Honda Civic Type R

Introducing a pioneering innovation – the world’s first all-carbon FK8 turbo inlet tube. Eventuri has dedicated extensive research and development efforts over several months to engineer an inlet that embodies perfection. The design focuses on three critical aspects: volume, flow quality, and temperature management. This turbo tube is tailored to integrate seamlessly with our FK8 intake system, incorporating the enhanced V2 MAF tube. The Eventuri FK8 Carbon Turbo Tube includes various components, each meticulously designed for a specific function and constructed to the utmost standards. By using 100% pre-preg carbon fiber and excluding fiberglass, Eventuri ensures a smoother internal surface to optimize airflow.

Volume

•  Inlet Diameters – Eventuri 78mm : Stock 63mm. By maintaining the MAF section diameter from the intake through to the turbo tube they have increased the cross sectional area by over 53% for the majority of the intake flow path to the turbo. Clearly with significantly larger internal diameter sizes, the Eventuri tube encapsulates a much larger internal volume which de-restricts the flow path to the turbo. This allows the turbo to operate more efficiently and spool up to peak boost levels faster. It also allows the turbo to operate at peak boost with less turbine loading.

Flow Quality

•  Having just a large internal volume is no good unless the flow path also allows for smooth airflow to the turbo. By using high temperature Prepreg Carbon Fiber they have managed to achieve a smooth internal surface. In contrast, the stock inlet tube is made from cast aluminum which ends up with a rough internal surface. This coupled with the smooth curvature of the elbow results in a flow path which minimizes turbulence.

Temperature

•  The final criteria was to minimize the conduction of heat into the airflow. The stock inlet is directly connected to the turbo and so immediately conducts heat as the turbo spools. The system uses a machined flange which connects to the turbo and then a silicon coupler with an integrated thermal spacer to keep the carbon elbow from having direct contact with the turbo. This barrier coupled with the low through-thickness thermal conductivity of carbon fiber results in less heat being transferred to the airflow.

Carbon Fiber Turbo Tube

• Crafted from Prepreg Carbon Fiber, the Turbo Tube is a one-piece design to maintain a smooth flow path to the turbo. It has an inlet diameter of 78mm internally which matches the MAF tube section and maintains this size for the majority of its length then smoothly tapering down to the stock turbo inlet. The stock turbo tube in comparison only has an internal diameter of 63mm. This difference in size equates to an increase in cross sectional area of over 53%. Furthermore, since it is made from Carbon, it has a much lower weight and lower thermal conductivity across the wall thickness than the stock cast aluminum tube.

Custom Silicon Hoses

• Eventuri’s silicon joiner hoses have been made to ensure a perfect fit and also to maintain smooth internal airflow. The main silicon hose at the inlet side has an internal step which mates against the turbo tube thus eliminating the potential of turbulence against the exposed wall thickness of the tube. The turbo coupler has a silicon spacer ring which separates the carbon from the metal turbo flange. This acts as a thermal barrier to reduce heat conduction from the hot turbo flange through to the carbon tube.

CNC Machined Turbo Flange

• CNC machined from aircraft grade aluminum and anodized, the flange provides a perfect fitment and seal against the stock turbo.

Notes

• This item is not eligible for return
• The Carbon Turbo Tube will only fit with the FK8 intake which has the updated V2 MAF tube. The V2 MAF tube retains the MAF section diameter all the way through and matches Turbo Tube. The MAF sensor also sits outside the airbox on the V2 MAF Tube. Originally the MAF tube reduced in diameter and the sensor was located inside the airbox as can be seen below. Eventuri has put together 2 packages depending on which MAF tube your Eventuri intake has. Owners who have the older V1 MAF tube will need to buy option 2 otherwise the turbo tube will NOT fit.

About Eventuri

Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance. After owning various intakes over many years for their own cars and being disappointed with the gains which seldom lived up to their claims – they decided to take things into our own hands and rewrite the book. To set a new benchmark in intake design and technology, above all – to engineer systems which provide real gains and then to publish genuine figures. Their systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing. They strive to publish all the development information to illustrate the depths they go to in bringing an intake from concept to reality. Only the best materials are selected for each component – even down to the choice of fasteners and fixings in order to ensure that the quality of the end product is second to none. After many years of disappointment with the usual aftermarket intakes, they are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve the performance of your vehicle.
