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

If you follow our Ford Powerstroke 6.0L product line, you are aware of the high- and low-temperature thermostats we released last year. The high-temperature unit quickly became a customer favorite as a reliable way to improve engine operation, in-cabin heat, and fuel mileage. These benefits are particularly useful in the cold-weather months. Our low-temperature thermostat offers a lower recovery temperature compared to the factory unit, which can help keep coolant temperatures regulated during towing or when transporting heavy loads.

During the release of the thermostats, we had numerous requests for a replacement housing. The factory housing is a casted piece, which isn't aesthetically pleasing, but it is easy to replace.

Product Development

Development began in a pretty simple fashion. We acquired an OEM housing and started capturing measurements so that we could reverse-engineer the piece.

Dyno preparation for Fiesta ST parts testing

Testing day has finally arrived and it's time to see how our new Fiesta ST parts perform! After weeks of prototype design and fabrication, we have our first prototype Ford Fiesta ST intake system ready for dyno testing. Our first round of product testing is being conducted for two reasons:

First, we want to evaluate power output. Our initial post explained that we were skeptical about making power with our intake. The Fiesta is a MAP-based vehicle and only uses its MAF sensor to gather temperature data. Through our years of development, extracting additional power from speed density (MAP-calculated) is a bit of a challenge. The gains we usually see on these vehicles is a result of reduced restriction within the intake tract. With this intake we've certainly improved flow, so let's see what we are able to produce.

Our second goal

Introduction and the Stock Downpipe

Another addition to the Fiesta ST collection! Our Fiesta build is coming along nicely, and I am happy to announce some progress on our downpipe project. As with any R&D undertaking the first step is to take a look at the stock setup and see how it can be improved.

Stock Fiesta ST downpipe

Although Ford has a pretty nice design, we are planning to make it a bit better by increasing the diameter of the downpipe to 3" throughout. As opposed to the stock unit which features 3" pipe only where the downpipe meets the turbo. In order to achieve excellent fitment with the turbo, we will keep the flange as similar to stock as possible. To collect the most accurate measurements

Mishimoto 1999-2005 Mazda Miata Oil Cooler Kit Pre-Sale!

The Mazda Miata MX-5 is the most-raced production vehicle in the world. It's a great top-down cruiser, features low entry-level pricing, and it's inexpensive to modify and repair. Fuel mileage is fantastic. Saying the Miata is the end-all and be-all vehicle would be a stretch (it has its limitations), but it is one hell of a car and an amazing bang-for-your buck regardless of use. If you do not understand any of this, I urge you to go out and drive one of these cars. If you've already driven one and still don't get it, perhaps you need to try again.

In all seriousness, the Miata is a fantastic car that deserves attention from the aftermarket. We offer a variety of cooling components for the NA/NB models, including several aluminum radiator options, electric

We're getting closer to dyno testing! Our intake piping and turbo inlet hose are now complete. A well-designed airbox is the last portion of our intake design before we begin performance testing. The airbox will provide a shield for the filter to reduce the impact of engine bay heat. It also allows us to create a volume for cold air to enter from the stock duct, routing directly to our filter.

The airbox design was pretty extensive for this project, so this is a long post. Sit back, crack open your favorite beverage, and read on!

Airbox Fabrication

We started this process with cardboard templates. These templates helped us quickly adjust and modify the shape and bends until we had a design that provided for appropriate clearance. The space between the battery and air duct is quite slender, so the design will need to be precise.

Another update on our E46 expansion tank project! Last time we showed off some images of our prototype unit, noting the numerous precise features we built into our design. This time we are installing the tank in our test vehicle to confirm fitment with the stock shroud and all coolant connection points. In addition, we will check out clearance between the tank and the belt-drive system to ensure appropriate fitment.

Removing the Stock BMW E46 Expansion Tank

First we need to remove the stock tank from our test vehicle. As you can see in the image above, the stock fan shroud is the first component to come out before we tackle the expansion

We've logged some miles (and smiles) during the testing of our two cat-back exhaust setups. We've decided on a strategy for the muffler selection, one that we feel best suits the tones of the Mustang EcoBoost (EB). Our team determined that the round muffler setup is just a touch too loud, and that the oval mufflers shown in the previous segment provided the exact sound we are seeking. Months of tedious design and testing have resulted in drone-less operation on the highway, improved volume at wide-open-throttle( WOT), and stock-like sounds during light/partial throttle.

I am sure you guys are eager for some final sound clips, but you will have to wait just a bit longer. In the meantime, we've settled on the muffler tip we will be using, and we've fitted it to our final prototype. Check out the process below!

Tip Design

We've gone with an appealing tip design for our EcoBoost Mustang exhaust system. Check out a few shots prior to mating this with the

This is a pretty cool post, something a bit out of the ordinary for our projects. We typically utilize our existing silicone boots in our intercooler kits, intake systems, etc. For this project, we decided to manufacture the first portion of our intake system from a wire-reinforced silicone hose. This would facilitate an easier installation, and it would also provide a smooth airflow transition from the small turbocharger compressor inlet to our intake's large pipe diameter. Since we like to show you what goes into developing our prototypes, check out the process for creating our silicone turbo inlet hose below!

Printing Our Fixture

The hose we have in mind will follow the path of the stock induction hose, which is actually a plastic piece on the stock ST. Before beginning our silicone project, we needed a fixture that would serve as a base for the silicone layers that will be applied. After making a model in Solidworks, we fired up the 3D printer and watched

Interested in purchasing our 6.0L intake elbow?

We're back with another update on our 6.0L Powerstroke intake elbow project! Last time we covered the stock unit and noted the plans we had for our rendition of the intake elbow. After collecting data from the stock piece, we began mapping our prototypes on 3D-modeling software.

Prototype 1

Our first prototype comes by way of the almighty 3D printer. We made a quick design in Solidworks to map out the appearance and dimensional constraints for our design.
