Eventuri Black Carbon Intake System - Mk5 Supra A90 B58

Eventuri was founded by ateamof engineers and enthusiasts with a background in Aeronautics and tuning all sharing a passion for cars and performance.After owning various intakes over manyyears for our own cars and being disappointed with thegains which seldom lived up to their claims we decided to take things into our own hands and rewrite the book. To set a new benchmark in intake design and technology, above all to engineer systems which provide real gains and then to publish genuine figures.

The MK5 Supra Eventuri intake has been developed to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures. Heat and Volume are the main considerations when designing an intake for turbocharged engines. In the Supra, the intake system is located next to the exhaust manifold which rapidly heat soaks the engine bay. High temperatures are detrimental for engine performance as the turbo would have to build boost with heated, less dense air and so the only way to ensure IATs are kept to a minimum is for a fully sealed intake. This however, results in a restriction with only one stock air feed to draw air in from.

During development we noticed an additional opening into the wheel arch area and took advantage of this by adding a secondary feed to our airbox. Furthermore our sealed airbox also has a heat shield with gold reflective to minimise the radiative heat transfer from the exhaust manifold. In order to maximise volume we made the airbox as large as possible with a recess for potential strut braces. The stock convoluted intake tube is replaced with a smooth carbon tube which is also larger in internal volume with a starting internal diameter of 111mm (4.4) smoothly tapering down to match the turbo inlet. The tube provides a smooth path from the filter to the turbo inlet. Finally we use a custom made high-flow dry filter which is ISO tested for filtration performance and has a larger filtration area than the stock filter.
