  1. We Struck Oil - Catch Can R&D, Part 1: Stock System Review

    We Struck Oil - Catch Can R&D, Part 1: Stock System Review

    Oil catch cans are a hotly debated topic, yet one fact is still irrefutable; oil blow-by will always be a real byproduct of the modern direct-injection engine. Intakes, charge pipes, and turbos all come into contact with the stuff over time. Sometimes, even newer, low mileage vehicles develop blow-by issues. With direct injection, fuel is injected directly into the cylinders, eventually resulting in carbon buildup on the valves. This was not an issue with port injection, since fuel injectors were placed in the intake manifold. The air-fuel mixture is sprayed directly on the valves, essentially cleaning them each time an injector fired.

    Carbon and oil buildup in direct-injection engines can negatively impact vital engine components and can result in an expensive fix later down the road. I can go into long, excruciatingly deep detail about the dangers of blow-by, but I've given you the basics of what you should know. For more information, I strongly suggest that you take a look

  2. Dyno Testing Results - MK7 GTI Induction, Part 3

    Dyno Testing Results - MK7 GTI Induction, Part 3

    The time has come to test our prototype design for the MK7 intake. After weeks of designing and fabrication, the prototype for this VW is now ready to hit our Dynapack dynamometer so we can collect some data.

    Testing these prototype MK7 GTI parts for overall power output gains over stock is important, so that's the first thing we needed to figure out. The larger diameter piping compared to the stock system provides increased airflow that will have a direct impact on improving power output. This car did happen to come with an aftermarket stage 1 tune on it, so we tested our intake with that software upgrade.

  3. The Stock Intake - MK7 GTI Induction, Part 1

    The Stock Intake - MK7 GTI Induction, Part 1

    We've got hot hatch fever! One of the newest vehicles to grace our garage, which happens to be our 3rd hatch for intake development, is the new 2015 VW GTI. Although Volkswagen was far from the first company with a hot hatch in its lineup, it was one of the first companies to really push the popularity of the design. VW is synonymous with the term "hot hatch" to most automotive enthusiasts. With the emergence of VW's newest GTI, it's time for us at Mishimoto to design our own intake for this turbocharged 2.0L engine.

    Newer GTIs can either come with or without a Secondary Air Injection (SAI) pipe. Basically, this is a system that forces more air into the exhaust during
