    The Civic Has Boost! - Intake R&D, Part 2: Prototype Development

    We are moving along with the intake project! Last time, we talked about the stock system and our goals for this project. Now, we will show you our process for assembling a prototype that we can test and analyze results from. Let's jump right in!

    Once our engineers finalize a design, the proposed idea gets modeled in 3D modeling software. The next step is to make the idea a physical reality. We have an awesome machine called a waterjet that can cut almost anything with pinpoint accuracy using a mixture of high pressure water and abrasive material. We upload our design to the waterjet through computer software, "telling" it exactly what we want to cut. The machine takes care of the rest! We just sit back and watch as our prototype gets crafted out of a big sheet of any metal we place inside the machine - in this case, steel.

    Prototype Fitment - Catch Can R&D, Part 2

    We are moving fast with this project! We have now talked about the differences and significance between two types of fuel injection, evaluated the stock system and began designing a bracket with our neat waterjet. We have also dived into the specifics of how our catch can works. Now, we have a working prototype that we have mounted onto our loaner Civic.

    We decided to go ahead and use the open space right behind passenger side of the motor that would conveniently place our catch can around the PCV ports. This will lighten any complexities in the hose routing.

  3. The Dyno Results - Camaro SS Intake, Part 3

    The Dyno Results - Camaro SS Intake, Part 3

    We have undertaken an intriguing project. The stock intake design for this 2016 Camaro SS is quite unique and working to increase performance has been a challenge, but here at Mishimoto, we welcome challenges! In the previous post, we went through the different iterations our Engineering Team had created, and we designed a prototype for testing. More testing was needed, however, before we could achieve the level of performance we wanted from this design. We will go through a detailed analysis of our final numbers for this Camaro cold-air intake project.

    Testing and Results - ND Miata Intake, Part 4

    We finally have an update for the Miata intake project!

    With our prototype now in working order, we were finally able to hook up our ND Miata to our dynamometer and get some pulls underway. At this point in the process, we knew we'd want to play around with some other design ideas while the car was hooked up to the Dynapack. AFRs, power output, and sound clips were all on the agenda for the evaluation of this prototype system.

    Stock System Review - Camaro SS Performance Intake, Part 1

    This brand new Camaro has been quite the buzz in the world of muscle cars. If you haven't viewed it already, we break down this new SS in great detail in our video review series on our engineering blog. You should check it out!

    2016 Camaro SS Video Review Series

    On to the intake. We want to help free up some of that airflow, as these cars have been restrictive in the past. However, Chevy does have an interesting stock intake design for this 6th-generation Camaro. Let's dive into it.

    Stock System Overview

  6. Prototype Sound Clips - ND Miata Intake, Part 3

    Prototype Sound Clips - ND Miata Intake, Part 3

    We want to be absolutely sure we are designing an intake that will provide what the MX-5 enthusiasts crave from such a product - sound, throttle response, looks, and of course, driving feel and performance.

    Our prototype is still in the testing process so we do not have dyno results quite yet. Instead, to hold everyone over till our next, more substantial update, we have some sound clips of the prototype being tested on our Dynapack. Keep in mind, this is just a prototype and does not feature any finalized production-quality components. We just wanted to give our readers a quick peek into what is going on behind the scenes.

    In the clip below, we have a short sound comparison of the stock intake vs. our prototype. The airbox lid is removed so you can clearly hear the sound. Some of the footage may look familiar, as it

    Dyno Testing and Results - Focus ST Intake, Part 3

    We have some dyno data for this Focus ST Intake! Along with sharing our performance improvements, we also have video clips of the intake lid both on and off, so you can clearly hear what is going on while the engine is under wide-open throttle.

    Our test vehicle is bone stock, with no aftermarket Focus ST parts, allowing us to provide a nice baseline for performance gains against the stock intake.

    Results

    In addition to using a fully enclosed airbox, the full 3 inch diameter piping extending all the way to the turbo ensured smooth, clean, and ample

  8. 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.

  9. Box and Pipe Fabrication - MK7 GTI Induction, Part 2

    Box and Pipe Fabrication - MK7 GTI Induction, Part 2

    The prototype for our MK7 GTI intake system will be unique. While designing the airbox, we needed to accommodate the factory mounting points, the battery cable routing, proper filter placement inside the box, and the stock fresh-air inlet scoop. Let's take a look at the gradual progression to a fully functioning prototype!

    We gathered some piping in our garage and tack-welded together an intake tube route. We then sorted through our air filters to locate an appropriate air filter that would fit within the constraints of the airbox we had in mind. The filter will be placed right next to the fresh-air inlet, optimizing the amount of fresh air that will pass through the pipe.

  10. The Prototype - ND Miata Intake, Part 2

    The Prototype - ND Miata Intake, Part 2

    The Engineering Department here at Mishimoto has been buzzing with activity around our new Miata intake design. We've just constructed a prototype pipe and box, bringing us even closer to dyno testing! Let's walk through the process.

    It's extremely important we pay close attention to detail on this project. From the beginning, we knew this box had to be made of aluminum, not steel, which is much too heavy. We also decided to utilize the factory air duct on this setup, so the box has an inlet accommodating that component.

    Airbox Construction

    The next few images show how we went about designing the air box. A major goal for the air box design was for it to be simple to install so utilizing factory mounting points was a must. Below, you'll see shots of the stock Miata intake system removed and a couple of our pieces being
