The Eventuri GR Corolla intake system is based on their GR Yaris system, with development including data logging of temperatures and flow rates, and dyno testing. Key considerations for this turbocharged engine were heat and volume .
The intake system aims to provide high flow rates and low intake temperatures. Its components are designed for a smooth, free-flowing path to the turbo . By creating a sealed system, the design improves upon the OEM airbox’s intake air temperatures while increasing internal volume to minimize pressure drop and turbo pumping losses . This enhances turbo efficiency and allows peak boost to be reached sooner, leading to performance gains .
The intake features a filter with a 210mm (8.3″) outer diameter and a filtration surface area exceeding 130,000mm² [1]. The patented Venturi housing is designed to offer maximum internal volume for the GR Corolla and provide laminar flow to the turbo pipe
