CARBON FIBRE TURBO TUBE | CIVIC FK8 TYPE R

The Eventuri FK8 Carbon Turbo Tube consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fibre with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow.

Information

The first option is for Eventuri intake owners who already have the updated V2 MAF tube and includes the Turbo Tube and required hardware.

The second option is for Eventuri intake owners who have the previous MAF tube. This package includes the Turbo Tube and the updated MAF tube.

Presenting a World First – an all carbon FK8 turbo inlet tube. We have invested months of intense R&D in developing an inlet which leaves no room for compromise. VOLUME – FLOW QUALITY – TEMPERATURE are the 3 main design criteria which we sought to meet.

1) VOLUME : Inlet Diameters – Eventuri 78mm : Stock 63mm. By maintaining the MAF section diameter from the intake through to the turbo tube we 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.

2) 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 Fibre we have managed to achieve a smooth internal surface. In contrast, the stock inlet tube is made from cast aluminium which ends up with a rough internal surface. This coupled with the smooth curvature of the elbow results in a flow path which minimises turbulence.

3) TEMPERATURE : The final criteria was to minimise 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. Our 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 fibre results in less heat being transferred to the airflow.

This turbo tube has been designed to fit our FK8 intake with the updated V2 MAF tube.

Crafted from Prepreg Carbon Fibre, 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 aluminium tube.

Our 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.

The Carbon Turbo Tube will only fit with our 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. We have 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.
