Eventuri Carbon intake system for Toyota Yaris GR

TOYOTA GR YARIS INTAKE SYSTEM BY EVENTURI

Power increase: 15hp, 18ft-lb

The GR Yaris Intake was developed through extensive data logging of temperatures, flow rates and dyno testing. Being a turbocharged engine, heat and volume were the main considerations during development. This intake system was engineered to provide the highest flow rate possible whilst maintaining the lowest intake temperatures. Every component was designed to provide a smooth and free flow path for the turbo. By using a sealed system we have improved the OEM airbox IAT's whilst increasing the internal volume to reduce pressure drop and therefore reduce pumping losses from the turbo. This allows the turbo to operate more efficiently and reach peak boost pressure sooner, resulting in a net power gain.

The filter itself has an outer diameter of 210mm or 8.3? with a filter area of ​​over 130,000mm^2. The patented Venturi housing is designed to provide the maximum possible internal volume for the GR Yaris and ensures laminar flow to the turbocharger.

The Eventuri Difference

The GR Yaris Eventuri system uses our patented carbon fiber housing which provides an aerodynamically efficient airflow path from the filter to the turbo. Not another cone filter with a heat shield, it is a unique design that induces the venturi effect and maintains laminar flow conditions to reduce drag on the turbo.

dyno tests

Our GR Yaris intake has been tested by various reputable tuners around the world, all of whom have reported similar results. The first dyno chart is from RaceCal in the UK. Several runs were made with the OEM airbox to get a repeatable result, and then again with the Eventuri intake. The tests were carried out on the same day with the bonnet closed. The results show an increase in torque and power across the entire rev range - not just at peak revs, which is why the car feels more responsive and can accelerate through the gears quicker. Ambient temperatures during this session were 11.9 degrees Celsius for the OEM airbox and 15.6 degrees Celsius for the Eventuri - the temperature increase is due to the dyno cell heating up after the runs with the stock airbox.

The second set of results comes from Master Tuning Asia in Hong Kong, who tested the intake against the stock airbox on the same day and this time in warmer conditions of around 32 degrees Celsius. The systems were tested three times and all three graphs show gains across the entire rev range, with the third run showing the highest gain as the stock airbox struggled with the IAT.
