  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!

    Interested in picking up our 2008-2014 WRX/STi overflow tank? Check out our discounted pre-sale linked below.

    2008-2014 Subaru WRX aluminum overflow tank pre-sale!

    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

  3. Power through Deletion. 2015 WRX TGV Delete Kit, Part 4: Product Testing

    Power through Deletion. 2015 WRX TGV Delete Kit, Part 4: Product Testing

    We've got some interesting plans to evaluate the performance benefits of our TGV delete kit. In addition, we want to evaluate any appreciable differences in terms of air temperature between the two materials (aluminum and Delrin) we have selected for our prototypes.

    Test Preparation

    For our first assessment, we will evaluate airflow temperatures in both materials during dyno testing. The goal here is to determine whether the different heat transfer properties of the two materials have an impact on the airflow within the TGV unit. Ideally we would use pre-TGV and post-TGV sensors to evaluate this, but for our initial test a single sensor will be used.

    We started by drilling and tapping each prototype.

    Initial Data

    We put together several plots to help analyze the data from our dyno pulls so we could reach a conclusion regarding appreciable temperature differences. First, a look at our initial runs with each material on

    Power through Deletion. 2015 WRX TGV Delete Kit, Part 3: First Prototypes

    We're back with another quick update on our TGV delete project for the 2015+ WRX. After designing our initial models and then 3D-printing a prototype for test fitting, we worked up a couple functional prototypes for on-car testing.

    First Prototype Images

    Check out a few images of our functional prototype deletes!

    3D-Printed Prototypes

    To confirm the dimensions and design of our prototype, we decided to utilize some of our rapid prototyping tools. We fired up our 3D printer and loaded the model. Check out a couple images showing the progress of the print.

    Once the printing process was complete, we cleaned up the prototypes and installed them on our 2015 WRX to verify fitment.

    Power Through Deletion. 2015 WRX TGV Delete Kit, Part 1: Design and 3D Prototypes

    It's been nearly two years since our first 2015 WRX development vehicle rolled into the shop. We've had a lot of fun with the car, and our team has developed a multitude of awesome components to aid in cooling, elevate power, and improve styling. Our product line is essentially complete, meaning we are done wrenching on our WRX. This is bitter sweet, as we will be picking up another vehicle to start the process once again. Before shipping out the WRX, we had one more project up our sleeves to extract a touch more power.

    With our existing modifications, including our downpipe, intake, and cat-back exhaust system, most customers are making in the neighborhood of 290 whp and 310 wtq. Not bad for some simple bolt-on modifications and ECU tuning. We've been eyeing TGV modifications and have seen the impressive effects on Subarus from previous model years. We decided to open up the intake system on our 2015 to see if we could design a delete system that would deliver a few extra ponies.

  7. Dyno Testing and Results - WRX Race Intake, Part 2

    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

    We've brought you two prototype designs thus far, and now we have one more weighted shift knob ready to pull from our knapsack and present to the public. These three designs are displayed in order from wild to mild, with our third design representing a more traditional shape. Hopefully, one of our new designs is something you could see yourself grabbing ahold of while ripping through some gears.

    3D Models

    As with our other designs, this life also began as a 3D model. Our Solidworks wizards went to work and quickly transformed an idea from sketches to a rendering. Check it out!

    We promised there would be more! Our first design presented Wednesday was pretty slick, and this next design is all about ergonomics and comfort. Not only did the design team work on the aesthetics, but we also spent some time ensuring that the feel of this knob would be ideal for slamming into gears while keeping your eyes pinned to the road.

    Initial Design Rendering

    As with our other weighted shift knob, this one also started in the 3D world. Check out a couple SolidWorks models showing the initial shape.

    Not all our projects involve in-depth data, heat-transfer calculations, or metal fabrication. From time to time our engineering team collaborates with our talented creative team to develop awesome accessories for your ride. These upgrades might not add power or drop temperatures, but they can surely improve the driving experience and offer an improvement in styling.

    In addition to the collaboration work, each design was created by a different member of our team. If you know any of these people, you might see where the designs reflect their personalities quite a bit.
