The BMW G20 B58 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 G20, 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 IAT’s 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.

Crafted from Prepreg Carbon Fiber, the airbox serves 2 objectives - to seal the filter against engine bay heat and to provide a dual cold air feed. Since the airbox is positioned next to the exhaust manifold it is crucial for the filter to be fully sealed so we designed the airbox to encapsulate the filter and at the same time provide a large internal volume. To seal the intake tube we have designed a laser cut plate with a rubber sealing strip which secures to the airbox. The intake tube passes through the plate and the rubber seal ensures heated air does not enter the airbox. To further minimise heat soak, there is an additional heat shield with a gold reflective layer on the exhaust manifold side which effectively combats the radiant heat transfer.

Having a fully sealed airbox results in the problem of having a restriction for the cold air feed. The stock airbox draws air from a single duct which extends to the front bumper area. During development we identified another area to draw cold air from which was a gap between the wheel arch and the chassis on which the airbox sits. To utilise this feed we extended a scoop at the back of our design which protrudes into the wheel arch and can even be seen after installation behind the front wheel. This second feed allows the turbo to draw from a larger area therefore reducing the restriction.

The Eventuri Difference

The G20 M340i B58 Eventuri system uses our Patented Carbon Fibre Housings with our Gen 2 bespoke filters, which provide an aerodynamically efficient airflow path from the filter to the turbos. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo. You can read more about the housing design and how it works HERE.

Note:

The G20 B58 OEM airbox system was updated in cars built after November 2018 where the airflow sensor was replaced with a temperature sensor in the inlet tube. Prior to this date, all airbox systems had an airflow sensor and for this reason we offer 2 variations. The V1 intake which has an inlet tube to take the MAF (airflow) sensor and the V2 intake for cars built after November 2018 which use a temperature sensor.

A bit repetitive
Format: Paperback
The Family Systems approach makes a great deal of sense and is very helpful. But this book seems to be somewhat formulaic - every case looks the same.

Extremely enlightening!
Format: Paperback
A psychologist recommended I read this book as my daughter and I were having issues. Wow! What you'll find in this book will change your whole thinking about relationships with family members. Very enlightening as to why we all behave as we do and what affect our behavior has on the development of our children. A MUST read for every parent. I bought a copy for each of our children and grandchildren to read.

Some good advice
Format: Paperback
Roberta Gilbert's "Extraordinary Relationships" offers useful advice for dealing with family relationships couched amidst an examination of systems theory. Although it is more technical than a lot of self help, it can be used by a general audience. Gilbert examines the theory of Murray Bowen, who countered notions of individual psychology (like those of Freud) with the theory that personality develops as a result of a family unit. The nuclear family, like a herd of amimals, reacts against each other, speaking a common language that is known only to them. Children raised in that family then detach from the family to form their own adult relationships, where dynamics may follow the family system. In order to heal adult problems, the author offers some practical advice, like taking the time to observe old patterns as they crop up (family Christmas fights come to mind) with the dispassionate mind of an observer. The author states that individuals will better be able to understand family dynamics and their role in them by doing this. I've read this book twice, and it has helped me better understand my family, and my role within it. I would recommend it for those who are seeking to better understand their family of origin, and what they can do to improve their present life through understanding the past.
