Eventuri carbon intake system for Toyota GR Yaris

TOYOTA GR YARIS INTAKE SYSTEM BY EVENTURI


Performance Upgrade : 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 primary design considerations. This intake system has been engineered to provide the highest possible flow rate while maintaining the lowest intake temperatures. Each component has been engineered to provide a smooth and free flow path for the turbo. By creating a sealed system, we've improved the OEM airbox's IAT's while increasing the internal volume to reduce pressure drop and therefore reduce turbo pumping losses. This allows the turbo to work more efficiently and reach peak boost pressure sooner, resulting in a net power gain.



The filter itself has an outside diameter of 210mm or 8.3? with a filter area of ​​over 130,000mm^2. The patented Venturi housing was developed to offer the maximum possible internal volume for the GR Yaris and ensures a 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. It's not another cone filter with a heat shield, it's a unique design that creates the Venturi effect and maintains laminar flow conditions to reduce turbo drag.



dyno tests


Our GR Yaris intake has been tested by various reputable tuners worldwide, all of whom have reported similar results. The first dyno chart is from RaceCal in the UK. Several runs were done 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 hood 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 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 test bench cell heating up after the runs with the production airbox.

The second set of results comes from Hong Kong-based Master Tuning Asia who tested the intake manifold 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 charts show gains across the rev range, with the third run showing the highest gain as the stock airbox struggled with the IAT.
