  1. Final Product Design - WRX Race Intake, Part 3

    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.

  2. 2008+ Subaru WRX/STI Aluminum Coolant Overflow Tank R&D Update!

    2008+ Subaru WRX/STI Aluminum Coolant Overflow Tank R&D Update!

    We last left you with some details of our initial design and a hint of an upcoming pre-sale for this overflow tank. Unfortunately, since that initial test fit we hit a few snags in the design process. Our goal with this product is to provide compatible fitment with all our other 2008+ WRX and STi components. This required numerous stages of test fitting, one of which revealed an issue. With our larger 3-row X-Line aluminum radiator installed, our sight tube on this expansion tank design ended up too close to the belt drive system on our Subaru.

    We decided a revision was necessary. Although the two components were not physically touching, the clearances were just too tight for our comfort. Luckily, our team had an

    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

    If you haven't noticed, the folks here at Mishimoto are not fans of plastic use for cooling system components. A large number of our products provide a more durable material, aluminum, to replace the failure-prone plastic parts, and now we are focusing on another line of products, our aluminum coolant expansion tanks. We offer two different options for the WRX/STI and one for the new Mustang EcoBoost. This article is focused around our newest addition, an aluminum overflow tank for the 2008+ WRX and STI.

    Product Design

    We won't be making any significant changes to the design of this tank compared to the stock unit, except for the construction material. Enlarging the tank's capacity will

  5. 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

    Mishimoto Subaru STI Performance Air Intake

    As noted earlier in this article series, we would be tackling a race intake system to go along with our bolt-on unit. So what makes the race system different? For this particular system we are using a larger-diameter intake pipe with a larger MAF housing. This means greater intake flow, but it also means it will no longer function with the factory tune. This system is meant specifically for drivers who want aggressive professional tunes so they can take advantage of airflow modifications such as larger turbochargers and high boost pressures.

    Because the 15' model shares the EJ from the previous generation, we would be using the same intake pipe and filter as we did with our 2008-2014 kit. This unit is shown below.

    So, all we truly needed

    After experimenting with some boxed designs in Part 1 of this write-up, it was time to turn our attention to a shrouded setup, similar to what we offer for the 2008-2014 models. We're hoping we could utilize the piping from our existing kit, which is well designed and has proven power gains. After placing the shroud into position, we found that it would certainly fit, but would require some modification. The fabrication work began! Check out a few shots taken during the process.

    Introduction

    Our team is finally working on some cool components for the new 2015 Subaru STI! As you know, the 2015 STI is essentially a hybrid of old and new Impreza components. It features the newer body style paired with the trusty EJ engine, instead of the new DIT motor featured in the WRX. We won't get into which is better or which we prefer, because we have nothing but praise for the updated chassis.
