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.

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.

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.

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 FK2 intake which has the V2 carbon MAF tube. We have put together 2 packages depending on which MAF tube your Eventuri intake has. Owners who have the small metal MAF tube will need to buy option 2 otherwise the turbo tube will NOT fit.

This turbo tube has been designed to fit our FK2 intake with the carbon MAF tube.

Our carbon elbow has been extensively tested on the road and on the dyno. We tested a fully tuned stage 2 FK2 and also a fully stock FK8. The tuned FK2 had stage 2 software, downpipe, exhaust, intake and methanol. At this level of tune the stock tube presents a restriction and so our larger tube allowed the engine to achieve more power all the way through the RPM range. We also tested a fully stock FK8 and although the OEM tube doesn’t present a restriction at this power level, the results show that the turbo still benefits from the larger tube since it is able to spool up faster and achieve peak boost earlier hence the gains under 4k rpm. The results show that the higher the demand from the turbo, the more benefit there is in using our carbon turbo inlet tube. Tests were done on the same day back to back with the hood closed and ambient temperatures were monitored for consistency. Several runs were carried out for each configuration to get a repeatable result.
