The New CorkSport Mazda 3 Rear Motor Mount

Feel like your SkyActiv-powered Mazda is lacking a bit of throttle response and driver feedback?

We hear you, that’s why we’re introducing the all new CorkSport Race Rear Motor Mount for 2014+ Mazda 3 and Mazda 6, as well as 2013+ Mazda CX-5.

Manufactured from 6061-T6 aluminum and anodized, the CorkSport Race RMM is strong, durable, and lightweight. What truly sets the CorkSport Race RMM apart from the competition goes to the 70a polyurethane. This RMM does not use polyurethane inserts that can loosen up and degrade. The 70a polyurethane is poured directly into the mount for a permanent bond with the aluminum body and bushing collar.

More than a handful of prototypes have been tested to ensure that the product arriving at your door is the very best it can be. We tested different durometer polyurethane from 60a to 80a (as well as different bushing sizes) to find the maximum improvement of throttle response and driver feedback without excessive noise, vibration, and harshness. Check out one of the prototypes below.

Now you might be thinking: “How does a motor mount improve throttle response and driver feedback?” In FWD vehicles it is typical for the engine to be oriented in a transverse layout. This means the engine is parallel to the axle centerline, whereas in a longitudinal layout (typical of V8’s and RWD vehicles) the engine is perpendicular to the axle centerline. Anyway, the engine/transmission applies a rotational force (torque) to the drive shafts, in turn rotating the wheels/tires forward.

“For every action there is an equal and opposite reaction.” – Newton’s third law of motion.

The amount of torque applied to the wheels is equal and opposite to what is applied to the engine itself, but what keeps the engine from just rotating? Enter the engine mounts. Unfortunately, the OEM engine mounts are very soft, so the engine is able to move and rotate substantially while driving. This makes for a very plush ride inside the cab, but sacrifices throttle response, driver feedback, and really the general driving experience. Replacing the RMM drastically reduces the amount of rotation the engine is allowed which in turn forces more of the engine’s torque to the tires sooner instead of just rotating the engine in the engine bay. This holds true for any action that affects the engine: throttle inputs, up-shifting, down-shifting…etc.

Improve your vehicle’s performance with the CorkSport Race RMM, and pair it up with the CorkSport Short Shift Plate and Shifter Bushings for the ultimate performance package!

The New CorkSport Steering Wheel for 2007-2009 Mazdaspeed 3

Looking to add a little style to the interior of your Genjuan? Or maybe you’re searching for another performance product to give you the edge? What if I told you I could give you both of those with one performance product?

Introducing the new CorkSport Performance Steering Wheel for 2007-2009 Mazdaspeed 3!

No stitching is required! The CorkSport Performance Steering Wheel was designed to be a direct OEM replacement. It works flawlessly with the OEM steering column, covers, button panels, and airbag for a stress-free 30-minute installation. Check out the images below: On the left shows exactly what you would receive in the package. On the right is a fully assembled steering wheel with all the OEM components.

Now I have to admit, when this product idea (Big thanks to Brett Ross!) came across my desk, I was a bit skeptical. I’m not one to spend money on aesthetics on my Mazdaspeed 3. So we got a prototype manufactured, and I installed it in my car to begin the R&D process. Within minutes, I was sold—and not just by how good it looked in my 09’ MS3, but by how much more connected I felt with the car.

Mazdaspeed 3 Steering Wheel for Better Driving Experience

While driving I saw the value in a performance steering wheel—things like the hand-wrapped and stitched leather that has a slight texture and plush feel to it. The perforated leather in the high-use areas is a great addition so your hands won’t get clammy on spirited drives. The wheel diameter is the same, but the thickness of the wheel has been increased, which is much more comfortable for long drives and canyon carving. The flat bottom gives it a more aggressive feel and actually makes it easier to get in and out of the car since I’m 6’ 2” tall. All that said, probably the most exciting feature of the CorkSport Performance Steering Wheel are the aggressive thumb grooves. These help you lock your hands in place, giving you more confidence in the twisty roads and while fighting the lovely torque steer.

Why You Need a New Mazdaspeed 3 Steering Wheel

Trust me when I say, you need to try the CorkSport Performance Mazdaspeed 3 Steering Wheel. You will be pleasantly surprised.

You Asked, We Answered: Our 2nd CorkSport and Mazda Q&A

Corksport Q&A

In January, we wrote a post answering questions our fans asked. It went over so well we wanted to do it again. Here are the top 7 questions we found on Facebook, Instagram, and Twitter:

Question: Would you guys consider making a turbo kit for the SkyActiv engines? What challenges would you face with that engine compared to the MZR engine?

Questioner: Michel Balk
Answer: There are a few key factors that would prove difficult to overcome when turbocharging a Skyactiv-G engine. First is the extremely high compression ratio of 13-14:1. High compression ratios and boost don’t mix well, and the supporting engine design to run that high of a compression ratio is very sensitive to major engine changes. For example: The exhaust manifold is a very well-engineered 4-2-1 design that is critical to running a high compression ratio on 87 octane fuel without pre-detonation. A typical turbo kit would replace the exhaust manifold which could cause many unknown issues. Second comes down to the overall design of the engine. Mazda has made it very clear they are chasing fuel economy, not white knuckle power. So, looking at that goal from a business standpoint, why would Mazda design the engine to handle 250+hp? That would only cost them more money. The engines are lightweight in every aspect: bearing size, connecting rods, pistons, crank…the list goes on. The SkyActiv-G engines are not built for power. Lastly, what good is a turbo kit if you can’t tune it correctly? As of right now there is not an effective method to tune the SkyActiv-powered vehicle. It’s unfortunate, but a turbo SkyActiv-G is a long shot.

Question: Give us all the info about the new CS turbo in production!

Questioner: Jeromy Williams
Answer: Well I can’t go and spill the beans, but I can give you a few tidbits of information. The goal of this turbocharger is not huge power numbers. Actually I would be in shock if anyone could get this to push 400whp with meth. The goal is to provide a turbocharger that cost only slightly more than a new K04 and is 100% bolt on. When I say bolt-on, I don’t mean “bolt-on” like BNR and ATP define it. This turbocharger requires no modifications to your current intake and exhaust systems; and no modifications need to be made to the oil and coolant lines. It’s like swapping in a new K04, but with much more power potential and no blue smoke. This effectively makes the turbocharger cheaper for the customer because none of the supporting sub-systems need to be upgraded or modified. As for some specs: Power is comparable to a BNR S3, and full spool is in the 3000-3200RPM range—depending on vehicle components. The current tune on my car is reaching 21PSI at 3200RPM with the CS EBCS running in bleed setup, and that’s on the prototype turbo without the billet compressor wheel.

Question: Will you be doing more products for Miata?

Questioner: Steve Linnehan
Answer: We are very excited about the new MX-5 Miata hitting our shores in the near future. The CorkSport sales manager is going to buy one as soon as possible. We plan to produce a respectable lineup of performance products for the new MX-5 Miata. From suspension to power, we will help you put some more pep in the Miata’s step, so stay tuned!

Question: What do I need to put more HP on my 2012 Mazda 3 2.0i SkyActiv?

Questioner: Brayam Calo
Answer: CorkSport has a couple options for your dilemma, Brayam. Combining our SRI, Cold Air Box, and Power Series Catback Exhaust System showed impressive gains for the little 2.0. On our dyno, the stock 2.0 made 118hp/110lbft, but when we added the components above, we saw power increase to 135hp/123lbft. This is a respectable increase in power for a naturally aspirated engine.

Question: What is an approximated max horsepower output that can be produced in an MS3 without upgrading turbo back?

Questioner: Christopher DeCaro
Answer: This is a difficult question to answer accurately as there are so many factors that play into the maximum power of an engine. The OEM downpipe is extremely restrictive on the MS3 and is commonly recommended as one of the first upgrades. Our dyno testing showed a 50hp increase over stock with only a Stage 2 intake, downpipe and racepipe installed. So as you add more components and eventually go with a larger turbocharger, the loss in power from the OEM downpipe will only increase.

Question: Is there a way to have the engine RPM drop faster while shifting or revving from an idle?

Questioner: Matt Zoomin Brown
Answer: The rate at which an engine can rev up or down comes down to simple physics: “Force = Mass x Acceleration”. You often hear of people upgrading their flywheel from the OEM steel piece to a lightweight steel or aluminum/steel two-piece flywheel. By reducing the weight of the flywheel and the rest of the rotating mass of the engine, you effectively reduce the amount of energy needed to make the engine rev up. The opposite works for revving down. The greater the mass of the rotating assembly, the more resistance need to stop the rotation—or the longer it takes to spin down. This is a result of the “Moment of Inertia” of the rotating mass.

Question: I would like to turbo my 2010 2.5 N/A Mazda 3, what do I need to know?

Questioner: Cynthia Senger
Answer: Like everyone else I’m going to recommend you sell your car and buy a car that was turbocharged from the factory, but for the sake of argument and fueling the fire I can point you in the right direction. The 2.5 N/A engine and the 2.3 turbo engine are very similar in design. I would start with buying a blown turbo engine, removing the exterior components, and then modifying them to work on your engine. Now the easy part is done… Next, you will need some way to tune the vehicle because turbocharging an engine that was not designed to be turbocharged is not a simple bolt-on affair. If you get past these two major hurdles, then bravo! Unfortunately, unless you improved the engine internals to handle this power, the engine will probably not live long with the added stress of its newfound power. Back to the first option: Buying a Mazdaspeed 3 makes a lot more sense in many aspects. Reliability, durability, and aftermarket support make big power much easier to achieve. Granted, a Mazdaspeed 3 may be more expensive to buy upfront, but I am almost certain it will be cheaper in the long run and will come with far fewer headaches and days without a car. I wish you the best of luck!

Thank you for your questions and keep them coming. We’ll have a Q&A every month for your Mazda performance questions.

Corksport Aluminum Crank Pulley for 2.0L & 2.5L SkyActiv Engines

Feeling like your SkyActiv powered Mazda isn’t getting the “shining” attention it deserves? Maybe you’ve already bought every CorkSport item you can, but just want more! I can’t blame you really; it’s a virus that all car fanatics fight. So here’s fuel for the fire! Introducing the aluminum crank pulley for 2.0L & 2.5L SkyActiv engines!

Manufactured from high-grade 6061-T6 aluminum, this precision machined crank pulley is sure to give you that extra level of detail you’ve been searching for. Plus it’s 100% designed and manufactured right here in the Pacific NW, USA.

This crank pulley isn’t just for looks folks, it’s got bite too! With a 68% weight reduction, compared to the OEM component, your engine is going to rev faster due to the lower moment of inertia of the rotating mass. I can’t guarantee your bum will feel the difference, but your 2.0L will.

You may also be wondering: “The OEM component is steel, will the aluminum be strong enough?” Absolutely! We’ve been testing the component on an employee car for 2 months (roughly 2000 miles) without a single issue. The accessory belts put a very small, almost insignificant, amount of force on the pulley. The real concern is the bolt that holds the pulley on, but we got that covered also, see below.

To be confident in the products we produce, we conduct FEA (Finite Element Analysis) on all applicable components. In this case it is the bolt clamping force holding the pulley on the crank. The crank pulley bolt is an M16x1.5 with a torque spec of 67-80 ft-lb. For this analysis I used 79 ft-lb which creates a clamping force of 7557 lbf. Looking at the color graph to the above, you can see that the maximum stress is ~12420 psi which is far below the material yield strength of ~40k psi. So what does this mean to you? You can (but shouldn’t) torque that bolt down to ~250 ft-lb without worrying about your beautiful new pulley being structurally damaged, but you will have to worry about getting that bolt out next time, that’s your own problem.

Add some shine to your engine bay and just a little more pep in your step. Keep an eye out for the product release in the near future! Offered in anodized black. Zoom – Zoom!
