  1. The Final Product - Focus ST Intake, Part 4

    The Final Product - Focus ST Intake, Part 4

    We have an update for our Focus ST intake project! Our first production sample has finally reached our R&D facility, and we have been able to test fit it onto a 2013 Ford Focus ST. Fitment was spot on, and we were able to get all the components properly snug into the car. We made some minor adjustments from our initial design and we included an awesome new feature that will help accommodate more Focus ST's on the road, so let's check it out!

    It's the Little Things

    During the time we were updating our design, we discovered small differences between the stock 2013"2015 and the 2016+ Focus ST intakes. The 2013"2015 Focus ST's have a screw type mass airflow (MAF) sensor that goes into the stock pipe. In the 2016+ model, however, the MAF sensor is replaced with an IAT sensor in the same location and it fits into a push-type clip housing. Many aftermarket intakes retain use of the stock accordion style boot that holds the sensor in place, " especially in

  2. Turn Up the Volume - Cat-Back Exhaust R&D, Part 4: Final Prototype

    Turn Up the Volume - Cat-Back Exhaust R&D, Part 4: Final Prototype

    It has been quite a while since our last update, and we are glad to be wrapping up this project! One of the reasons for this delay is that, based on your feedback, we have decided to add a few more options for this exhaust system.

    You might remember from a previous post, that our engineers enjoyed the louder sound of our non-resonated exhaust after having listened to both the resonated and non-resonated versions. Since there were no improvements in horsepower with either option, we based our decision to create the exhaust on sound only.

    To refresh your memory, here are some photos of the resonated and non-resonated sections of the exhaust. Aside from this small difference, the rest of the exhaust layout is the same.

  3. The Civic Has Boost! - Intake R&D, Part 1: Stock System

    The Civic Has Boost! - Intake R&D, Part 1: Stock System

    Some exciting news in the Mishimoto garage - we have finally been graced with a brand new 2016 Honda Civic with the 1.5L turbo engine! We have planned our R&D process for the design of a performance intake and we are starting this project by dissecting the stock system so we can learn as much as possible. Let's jump right in!

    The Stock Intake

    Honda has done an excellent job with their new Earth Dreams 1.5L motor. This turbocharged engine has a power output rated at an impressive 174hp, which is a nice amount of power for this new-age Civic. We are very excited about this chassis and we are eager to dig in and develop an awesome intake

  4. Prototype Fitment - Catch Can R&D, Part 2

    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.

    Treat Your Transmission. Ford 6.0L Powerstroke Transmission Cooler R&D, Part 3: Testing Data

    It's now time to install our prototype and put some data behind the efficiency differences we expect to see between our cooler and the factory heat exchanger. We did add a substantial amount of core surface area, so we anticipate that heat transfer will improve during a load test. Check out this shot of the Mishimoto 6.0L transmission cooler installed!

    Testing Process

    We have numerous tools at our disposal to test heat exchangers. For this one, we will be using our Dynapack™ dynamometer. With a transmission cooler test, we want to apply some load on the vehicle to ensure that stress is created within the drivetrain. We

    Design and Fabrication - Catch Can R&D, Part 1

    We have been searching long and hard to get our hands on the new Honda Civic, and the search is now over! A brand new 2016+ Honda Civic equipped with the 1.5L Turbo engine has finally reached our R&D facility, thanks to a very generous owner. One of our first targeted projects is an oil catch can. There are many benefits to equipping a vehicle with a catch can. Modern fuel injection is accomplished by either port or direct injection, the latter used by this Civic. Let's briefly talk about the differences between the two.

    Port vs. Direct Injection

    With port injection, the fuel injectors are situated right inside the intake manifold, producing a fuel stream to mix with the air. That air/fuel mixture is shot straight into the combustion chamber through a valve. As the fuel passes through the valve area, much of the debris gets cleaned off - because as we all know, gasoline is an excellent solvent.

    Direct injection, however, is the more common

    Beat The Heat! Mishimoto Fiesta ST Intercooler R&D, Part 6: Prototype Testing Round 2

    We are narrowing down our selection of core designs through both extensive research and some pretty neat testing processes. After seeing some impressive heat transfer numbers on our first round of Ford Fiesta ST intercooler testing, we decided to focus on producing a better balance between pressure drop and reduction of intake temperatures.

    New prototypes were constructed, and we were ready to make some dyno runs.

  8. Flex-Free Cornering. Fiesta ST Trunk Brace R&D, Part 4: Testing Data

    Flex-Free Cornering. Fiesta ST Trunk Brace R&D, Part 4: Testing Data

    The testing of our Fiesta ST rear strut brace involved three different driving conditions.

    Cornering: 30-40 mph, slalom

    Braking: 50-0 mph, stop with ABS engaged

    Acceleration: 0-60 mph, full-throttle run

    Each setup (with and without brace) was tested on the same day on an identical surface and with the same driver. The tests are repeatable and will provide an accurate comparison of rigidity in the rear body portion of our Fiesta.

    Results

    Check out the plot below to see our testing results.

    These data points confirm our theory that the addition of bracing in this area of the ST does indeed have an impact on flex. Although flex in these conditions

    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.

    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

  10. The Testing Phase - Mini Cooper Intake Development, Part 3

    The Testing Phase - Mini Cooper Intake Development, Part 3

    We have another update ready to share with the Mini world! In the last post, we went through the process of how this shield was constructed using the waterjet. Now that all the components have been completely assembled, it's time to test and evaluate our system. Check out some sound clips below!

    Our intake dramatically improves the induction sound. The turbo spool is much more pronounced over stock and the intake tone is more aggressive. We know that this is as important for Mini drivers as performance, so we devoted time to making sure that this intake sounds awesome.

    The way this intake is designed fully maxes out airflow potential that the engine sees. It is less restrictive than the stock unit while still making
