    DYNO TESTING AND RESULTS – WRX RACE INTAKE, PART 2


    It has been a while since we have updated this project, but we now have something for our WRX community!

    The brief data report below shows our gains with this race intake project and our baseline was a fully stock 2015 WRX with no upgrade or aftermarket tune. The numbers are quite high due to the upgrades already installed on the WRX during testing. These upgrades included our Mishimoto:

    • Downpipe
    • Cat-Back Exhaust
    • Front-Mount Intercooler
    • Custom Engine tune

    The graph above shows that the race intake coupled with the Mishimoto upgrades netted peak gains of about 77hp with 88ft-lb of torque, and max gains of about 86hp and 98ft-lb of torque against a fully stock WRX. Considering the vehicle’s bolt-on additions and custom tune, we were expecting big gains. Of course, such large gains are possible only with the installed upgrades, but our intake and a proper tune contributed as well.

    Regardless of any bolt-on upgrades, it is important to note that this intake will need to be accompanied by a tune. The larger-diameter piping and MAF (mass airflow) housing will not work with the stock ECU tune. For those who may, for example, have some, or maybe all of the bolt on upgrades already installed on their car, they can expect larger gains over those who are fully stock. The exact power gains that you see with our Race Intake will ultimately depend on your specific modifications and tune.

     

    FINAL PRODUCT DESIGN – WRX RACE INTAKE, PART 3

    Our last update on this intake included dyno testing that yielded some interesting numbers. Now that we’re moving closer to the release, let’s take a look at the finished product!

    Let’s start with the intake pipes.

    New 2015 WRX parts

    These intake pipes will be finished in either wrinkle black, wrinkle red or polished, as shown above. The decision is up to you! These production samples came out nicely and look really great in person. Remember we are using full three inch piping with no step downs, which will require a tune on any WRX that has this race intake installed.

    Each pipe will come with a built-in mass airflow (MAF) straightener to help with consistent airflow. Straighteners are very helpful in assisting the MAF sensor to record accurate readings and take turbulent airflow out of the equation. Let’s also not forget that the MAF housing adapter is CNC-machined onto the pipe!

    Pictured above is the filter we plan on using for this kit. It is larger and has more surface area than our Performance Intake version. Now let’s look at the box!

    This box surrounds the air filter to help keep it shielded from the hot air the engine will radiate. The box is made entirely of steel and is powder coated black.

    That does it for the components of our Race Intake kit! We will also include an extended wiring harness for the MAF sensor, pictured above behind the intake pipes.
