CorkSport Throttle Body Spacer

We are proud to introduce the CorkSport 72mm Throttle Body Spacer for Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7 Turbo.

This is a great product for those Mazdaspeed owners who want push past the limits of their OEM fuel system. We’ve carefully chosen nozzle locations, upgraded the inside diameter, and added an O-ring for quick and easy sealing. We designed the CS throttle body spacer to eliminate a lot of the headaches that come with adding extra fuel.

The area where the throttle body mounts is pretty tight on the Mazdaspeeds which leaves few options for adding methanol nozzles, especially the tall AEM ones. We realized right away that nozzle orientation was critical.

To prevent any modification, the top nozzle location sits at an angle that perfectly clears both the OEM & CorkSport Intake Manifold to provide an access port for most meth nozzle styles on the market. For more stealthy setups, there are two ports located on the bottom side of the CS spacer, one straight down and once again at an angle for easy usability without further modification.

We also considered nozzle depth when designing the CorkSport Throttle Body Spacer. Most nozzle styles will sit flush to the inside surface of the spacer. This prevents any irregular airflow around the nozzle locations without affecting the spray pattern of the nozzles.

Just like the CorkSport Performance Throttle Body, we enlarged the inner diameter of the throttle body spacer to 72mm. This is the maximum size that can be used with the OEM bolt pattern and ensures optimal best airflow. The OEM throttle body & gasket can still be used with no issues.

Each CorkSport Throttle Body Spacer is precision machined from 6061-T6 aluminum before being anodized black for a clean and durable look. An O-ring groove is added during machining to allow the spacer proper sealing to your intake manifold. Rest assured, the O-ring is safe with all fuels and even oil. Finally, the spacers are laser etched with a CorkSport logo for a subtle finishing touch. The entire package is wrapped up with hardware; including extended length throttle body mounting bolts & two NPT plugs for the nozzle/injector ports you are not using.

If you’re running out of fuel in your Speed and we can make installing a methanol system much easier, pick up a CorkSport Throttle Body Spacer.

Creating CorkSport Parts with 3D Scanning

While creating a new CorkSport part, we sometimes run into issues where calipers, bore gauges, and angle finders are simply not enough to get the measurements we need.  We’ve discussed how we use 3D printing in a previous blog, but today I thought I’d go over the opposite: 3D scanning.

Where 3D printing takes a CAD design from computer to physical part, 3D scanning takes a physical part and converts it into a computerized model. This is especially useful for things like intercooler piping, intake design, and even creating exterior body parts. What these components all have in common is that they are a complex, difficult to measure, shape where fitment is critical. Check out the 3D scan below from the development of our GEN2 Mazdaspeed 3 front lip. While not a perfect replica, this 3D scan information was vital for designing the CS front lip to ensure great fitment and stylish look.

At CorkSport, we do have a small 3D measuring arm that can take measurements of 3D objects and input them directly into a CAD program. The arm does this by first having a “home” position established that the arm can measure from. Then as the arm is moved around, it knows how far the tip of the arm is from the home position in x, y, and z coordinates. This is a very basic form of 3D measurement as the arm must actually touch the surfaces of the part. Mostly simple information like mounting surface locations, angles, and hole sizes can result from this arm. While not a full 3D scan, it is especially useful for things like the GEN3 Transmission Motor Mount that have mounting planes at different angles.

For intercooler piping with completely round surfaces and bends, CorkSport’s 3D measuring arm has its limitations. We typically get a full 3D scan performed on the OEM piping to give us solid locations and a great visual reference to design from. The 3D scanning arm bounces a laser off the part to determine its shape and size. Then, software that accompanies the 3D scanner stitches all the information together into a full 3D CAD model. The scans achieve great accuracy; check out the embossed writing and even texture on this OEM intercooler piping for the SkyActiv 2.5T.

From this point, we design the new CorkSport parts. In terms of intercooler piping, we analyze where the larger piping will fit to get the performance gains we want. In some cases, we can also simplify the pipe routing to get smoother airflow than the OEM piping. Having a full OEM piping scan makes this much easier as we can easily double check our measurements with the OEM parts on the car. As a result, our first 3D print can often be the final version before having metal parts made. An early design for an upgraded Mazda 6 SkyActiv 2.5T hot pipe is shown below (blue) with the OEM part scan (gray). The routing was carefully chosen to achieve our desired piping size within the constraints of the OEM engine bay.

 

3D scanning has a huge range of uses and we are just beginning to explore the full capabilities. Be sure to share your ideas on how we should use this technology and what new CS parts we should make with 3D scanning’s help!

Mazda’s Dynamic Pressure Turbo – An Introduction

The SkyActiv 2.5T has been around for a few years in the CX-9 however, things started to get interesting when the engine was dropped in the Mazda 6 for 2018. While lacking a manual and not a true Mazdaspeed, it’s a step in the right direction for the enthusiast. With one of the new Mazda 6s in the CorkSport garage, we’ve been getting curious about where all of that 310lb-ft comes from. Well we decided to call up Mazda and purchase a turbo to see how it all works.

There’s a lot to take in on the turbocharger and there are quite a few things that have changed from the K04 that made its home in the Speeds.

For starters, this turbocharger is pretty big. The wheels themselves are not large, with the compressor wheel very close in size to the old K04 & the turbine wheel only slightly larger than the K04. However, with the dual inlet turbine housing, 90° compressor outlet, and lots of attached electronics, the whole package takes up a lot of room in your engine bay.

The turbine housing is not far from the old K04. A large five-bolt inlet flange has two rectangular inlets to work with the dynamic pressure system (more on that later) and even a port where the EGR system sources its exhaust gases. The outlet is much simpler, using a five-bolt flange to mount to the downpipe, yet does house a surprisingly large wastegate port.

From a performance standpoint, the large wastegate should help eliminate boost creep but the turbine housing will likely need a larger scroll to get some more serious power out of the engine.

The compressor side is packed full of features. As usual, the wastegate actuator bolts to the compressor housing, however, Mazda has switched to an electric actuator. Interestingly, the bypass valve is also electric and is even mounted to the face of the compressor housing.

Some fancy casting design leaves a pathway between the high and low-pressure sides of the compressor and lets the BPV decide when the passage is open or closed. These two electric actuators will mean easy and consistent boost control. The final plastic component on the housing we believe is a boost assisted vacuum source for the vehicle. Finally, the inlet is a typical clamp connection while the outlet uses a 90° turn and two-bolt flange for better accessibility around the wastegate actuator.

With the housings removed, the CHRA of the dynamic pressure turbo is very simple & standard. Oil feed in the top, two-bolt oil drain in the bottom, and standard crossflow engine coolant ports. The compressor wheel is a cast 6×6 unit and turbine wheel is a basic 11 blade unit.

We are looking forward to waking up the Sky-T in the coming months and making the 2018+ MZ6 into something a little closer to a Speed. Stayed tuned, there’s much more fun to be had from the 2.5T!

CorkSport Steering Wheel for ND Miatas

We love the look and feel of the CorkSport Mazdaspeed steering wheels and thought we would throw some love to the Miata guys. Designed to inspire confidence during aggressive driving while improving day to day comfort, this steering wheel is a complete package and will complement your other CorkSport Performance Upgrades.  

 

The CorkSport Steering wheel is a direct OE replacement as it retains all trim, buttons, airbag, and even paddle shifters for automatic models. It’s also a perfect fit for all ND Miata models (yes even those of you with a RF). Check out the image below, it shows exactly what you will get in the box (right) next to an assembled performance steering wheel (left). Once you remove your OE wheel you just need to transfer all of the trim and accessories and you’re ready to install.

 

 

In designing the wheel we knew we wanted performance without sacrificing comfort. Let’s face it, the steering wheel is the one thing you are (hopefully) always touching while driving. We knew right away we wanted a thicker wheel as the stock one is awkwardly thin. We increased thickness without increasing the overall diameter of the wheel.

 

The flat bottom of the wheel makes it easier to get in and out of the car, especially for those of us who barely fit in Miatas anyways. To further enhance the aggressive style we added a center stripe to the top of the wheel. Finally we carried over the deep thumb grooves from the CorkSport Mazdaspeed 3 steering wheels to really lock your hands in place during spirited driving.

 

All of the features are wrapped up in plush black leather, with perforated leather on the high use areas to keep your hands cool. If that wasn’t enough we’ve also added an option for alcantara inserts. Why?  Because Racecar!

 

If you’re looking for an easy mod that will upgrade the feel, comfort, and style of your ND Mx5 let the CorkSport Steering Wheel find a home in your interior.
