    Testing Results - The FXT Intake, Part 3

    Last time we posted about this Forester XT intake project, we left you off with prototype fitment. Testing is now complete and we have some information to share.

    IMG_0157r Subaru Forester XT performance parts up for testing

    Our initial goal for this project was to design a performance intake system that would deliver dyno proven power gains and while being safe to run on the stock tune. We designed a very similar system for the 2015+ WRX and achieved terrific results.

    The Forester XT has changes in the ECU, head design and cams, so the testing has yet to give us the results we want to see. We've tested numerous different designs over the past few months and we haven't seen results that we're happy with yet. We've designed prototypes that make power on

    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.

    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.

  3. Prototype Fabrication and Fitment - The FXT Intake, Part 2

    Prototype Fabrication and Fitment - The FXT Intake, Part 2

    The progress on our intake system is coming along nicely for this Forester XT. We have created a pipe that will fit well with our airbox design and filter selection. Remember, our pipe is within the acceptable pipe diameter to run this system with a stock tune.

    The Fabricated Prototype

    Below are some shots of the system we plan to put on an FXT for testing. The routing for this tube will follow a more direct path from filter to turbo. This is especially helpful for when the car is sitting at idle with ambient air around the box. With a shorter pipe distance, it will take less time for fresher, cooler air to get to the engine upon acceleration over stock. Check out images of the initial design below!

  4. Stock System Evaluation - The FXT Intake, Part 1

    Stock System Evaluation - The FXT Intake, Part 1

    Exciting things are happening in the induction world here at Mishimoto. We have a 2014 Subaru Forester XT in for intake R&D. This AWD turbo Subaru comes with a 2.0L power-plant, giving an output of 253 hp from factory. It shares the same FA20 heart with its 2015+ WRX counterpart, so there are some similarities between the two.

    Stock System Review

    The stock Forester XT intake system is somewhat similar to the stock WRX intake system, yet featured some differences in shape and size. With both systems, the airbox is tucked away in the engine bay. To an untrained eye, it can be easy to miss upon first glance.

    The airbox mounting points on the vehicle are also quite different

    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

  6. R&D Beginnings - WRX Race Intake, Part 1

    R&D Beginnings - WRX Race Intake, Part 1

    Team Mishi likes to look out for our Subaru community. If you have been following our engineering blog, then you'll notice that we have been rolling out a slew of high quality 2015+ parts WRX. One of the biggest products we launched was our bolt-on intake system. Not only did we provide easy power gains, but our system greatly improved sound, and created a large group of very pleased customers. The gains we produced were a result of reduced restrictions compared to the factory system. A great product that supports stock and mildly modified examples. We are now turning our attention to an even less restrictive iteration that will be designed to support vehicles necessitating maximum airflow.

    Our race-inspired design for this WRX intake will take the more aggressive route of obtaining the maximum power potential an intake can deliver to this FA series motor. Keep in mind, this secondary "Race" design will require tuning for safe operation.

    It is important to understand that this

    We're back for some more fan shroud fabrication! The last portion of this series highlighted the beginning stages of initial shroud design. The BRZ/FR-S uses a fairly unique overflow tank that mounts directly to the factory fan shroud. This is our first target for part two of product design.

    Overflow Tank Mount Fabrication

    This tank has two upper mounting points which use a bolt which passes through the tank material and into threads on the shroud. We utilized round stock aluminum which was cut to the proper length, drilled, and tapped for the appropriate factory bolt. These were then welded to the shroud in a position that would place the tank in the

    Taking a look at our lineup of products for the BRZ/FR-S reveals a solid offering in both cooling performance and power-adding upgrades. Our engineering team has evaluated numerous vehicle systems and provided upgrade components where solutions were needed. Our intake components provide improved induction noise and nice increases in power. Our oil cooler system provides a solution for high oil temperatures on the track. And, our performance aluminum radiator is ideal for track vehicle owners looking for some additional peace of mind during long-duration lapping. These are just a few of the components we currently offer, and we've managed to find yet another opportunity to provide an awesome

    After solidifying our product design we needed to capture data to verify the design and determine if any changes were necessary. We strapped our test vehicle to the dyno and began making pulls! Check out a compilation video from the dyno testing. The audible difference in intake tone and volume is quite noticeable when comparing the stock setup with the Mishimoto prototype.

    Subaru BRZ / Scion FR-S Performance Air Intake

    We left off last time with an explanation of our intentions with this intake system and some initial design work to create an induction route to our planned airbox. Now it was time to finish designing this intake system so that testing could be conducted.

    Airbox Fabrication

    We started developing our airbox with simple metal fabrication. The plan was to put our idea into a physical object and then transfer this to a 3D model. Once in Solidworks, we could solidify the final design and features and use our 3D printer to construct a final prototype for test fitting.

    Fabrication begins! A simple box was drawn up and templates printed for our bends and mounting point locations.
