Our WR evo ix project
All started from our love and passion for efficiency and performance, designing building and testing our own parts. Developing parts and solutions for making the highest efficiency 4 cylinder engine, we bought an Evo ix for testing and developing. Very quickly transforming an 88% efficiency normal 4g63 engine to a 11.000rpm high cr engine.
Around 15psi boost and 800hp.
In this platform, we develop not only engine parts but also turbochargers, intake manifolds, exhaust manifolds, transmission systems and anything would help us to make the step beyond.
Daily we design and manufactured new parts, improving them day by day.
