Dear Mazda, I have a Wish List

Dear Mazda,

I want to let you know what’s on my wish-list so that if you ever happen to stumble upon our wonderful little world of CorkSport, you’ll see everything I’ve been dreaming of.

1.      New Mazdaspeed

While I personally prefer the Mazdaspeed3 hatchback look, I’d even be ok with a Mazdaspeed6 iteration. I like to have fun; I like to be pushed back in my seat by power and performance, and realistically I LIKE TO GO FAST. The newest generations of Mazda are missing some of these aspects, and I’ve been dreaming of their return!!

Now, don’t get me wrong, I like the Gen3 Mazda3. It’s a smooth ride, and we’re pretty stoked about what it can offer. However, our customers like to make power, N/A leaves us begging for more despite what HP we can squeeze out of the Mazda3.

So, Dear Mazda, Please bring back the Mazdaspeed!

2.      Mazda CX-3 with a turbo

Genuinely, I like the look of the CX3, I enjoy the size of the CX-3 and even find that it suits my ever changing lifestyle being a little higher off the ground. (For those who don’t, check out CorkSport’s lowering springs for the CX-3). It’s just flat out missing the power that comes with a turbo. It’s “get up and go” is … well… slow. This could, with the right improvements, be a great replacement for the Mazdaspeed3 for those of us waiting for the newest generation. Just please, please, can we get some more POWER?!

3.     Turbo Diesel Mazda 6

You gave it to everyone else!!! Why in the world would you leave us out?! You have to do ZERO redesigns; just getting it to the states is all I’m asking. The clean look of the Gen3 Mazda6 is something we like, but the power and improvements that come with the Turbo Diesel, I mean COME ON?! Just let us have a chance at it!

Heck, make that an AWD Mazda 6.

If you’re feeling generous, you could make it an AWD Turbo Diesel Mazda 6.

If we’re going THAT far, make it an AWD Turbo Diesel Mazda 6 wagon, because “I love me some hatchback!” that big booty look, and being able to fit all of the things… What’s not to love?!

It’s not a long list, and I realize that it’s selfish of me to ask, but I’m pretty sure I’m not the only one you would be making happy if you would just deliver on even ONE of these items.

Hopefully yours,

Kim@CorkSport

 

P.S Apple Carplay, and Android Auto… have been in the works for about 3 years, and you probably could have just hired a coder and completed a custom code in half the time… so we’re still waiting for that one too.

CorkSport BIG Turbo for the Mazdaspeed & CX-7

Mazdaspeed 3 big turbo upgrade

Good day boosted enthusiast!

We wanted to take some time to give you all a quick update on one of the many projects we have brewing up here at CorkSport Headquarters.

The project I’m referencing, in general, is our 2nd turbocharger upgrade for the Mazdaspeed 3, Mazdaspeed 6, and CX-7. This unit is a substantial upgrade over our current 18G turbocharger. This Turbo will cater to those looking to take their performance and power goals to a higher level.

Not only will it be capable of putting you well into the 465whp range but this CorkSport Turbo upgrade will be able to do it without giving up on reliability and throttle response.  

It will be very beneficial to those who have mildly-built blocks and a supporting fuel system that will allow them to get higher in the HP range.

So, let’s talk about some of the features you can expect on the upgrade and why we decided to utilize them.

Let’s start at the heart of the Turbocharger.

The new CorkSport Mazdaspeed turbo will take full use of a GTX3076R center housing and rotating assembly (CHRA). The unit is equipped with a fully sealed ball-bearing cartridge, which is a nice upgrade when compared to a standard journal-bearing unit. We chose to go with a ball-bearing unit for a few reasons.

  1. The enclosed design of a ball bearing system allows us to eliminate the need for a thrust bearing, which can account for about 40% of the bearing system drag on the turbo rotor assembly.
  2. Ball bearings reduce the viscous drag, which allows a ball-bearing unit the ability to spool up about 15% faster than its journal-bearing equivalent.

The next thing you will notice on the new Mazdaspeed Turbocharger upgrade is the holes that are drilled into the compressor cover. These little holes are known as anti-surge ports and are intended to expand the turbochargers compressor map. The ports function to move the surge line further left on the compressor map which gives the Mazdaspeed turbo some more headroom before it falls out of its efficiency island. Anti-surge ports are becoming increasingly popular in modern performance turbochargers and with great reason. They offer some unique benefits as mentioned and will be fully integrated into our unit.

Last but not least, as with our CorkSport Turbo, this bigger Mazdaspeed Turbo will once-again be a true drop-in unit; minus the 4” compressor inlet.

There will be no cutting, modifying, sourcing oil and coolant lines, running to the store to buy couplers, etc. This unit will come with everything you need to have a trouble-free install. As with the current CorkSport 18G turbocharger, the new Garrett-based design will come with all studs, gaskets, washers, and knowledge that you need to have a nice weekend install.

So keep your eyes peeled as we get closer to delivering more performance for the Mazda community!

Kill The Nannies – How to Overcome Mazda’s Safety Measures for Racing

Nannies. One thing we have discovered while racing our Mazda 3 is that the OEM safety systems in the newest generation of Mazda 3 work well, too well in fact for racing.

Each year, new safety features are added by Mazda which make the cars safer and reduces the risk of collisions. This is great for day-to-day driving and commuting, but it presents a problem if you plan to take your car to the track to race it.

The OEM system in the car really frowns on lifting a rear tire off the ground, or when you get wheel spin accelerating out of a slow-speed corner. They design the cars against these things happening for safety purposes (understandably). However, Mazda does give you a button on your dash to turn off the traction control. This gets us racers around the limitations to a certain degree.

Let me explain:

When you disengage traction control, the system which measures yaw/pitch and ensures your car has all the wheels on the ground is actually still working, even with the button off. What the button does essentially is give you a sort of leash with more leeway, until the computer thinks you have gone too far of course, then it will kick in traction control again.

So, how do we get past these nanny systems so we can push our cars for maximum performance?

Can you simply unplug the computer which controls the this? I wish it were that simple, but you cannot. The systems in the car are all tied to each other, and the car may not start, it may not run safely, or it may run in a limp mode. A good example of this in our 2015 Mazda3 is: if you unplug the rearview mirror the car won’t start. The ABS is also controlled by the same unit, and this is very handy to have on the track.  The ABS is very good in the Mazda3 by the way, so I recommend you keep it.

The solution we’ve come up with at CorkSport is pretty simple: Leave the computer plugged in and turn it over.

That’s it, simple, nothing else is required. What happens when you turn the computer upside down is the computer loses its physical reference point, so it defaults by turning off the stability control and nannies, but most-importantly, the ABS still functions.

A big word of caution: The computer which controls the nannies also runs the airbags. If you race your car on the track, the airbags will have been removed from your car already. DO NOT drive your airbag-equipped car with the module flipped over.

The reason this solution works for the track is that our Mazda 3 race car has additional safety equipment installed, with the 6-point harness and halo seat, along with the rest of the driver’s safety gear, that keep you from injury in the event of any wrecks.

FYI: When using this “hack”, your Mazda 3 dashboard will light up like a Christmas tree from all of the warnings; but that is a small price to pay for the improved performance while racing.

–Derrick

DISCLAIMER: This modification is for racing purposes ONLY. Doing so will render many of your car’s safety systems ineffective. Installing other safety systems after this modification is essential.

2018 Mazda 3 CBR – Transmission Modes Comparison

If you didn’t know already, CorkSport recently bought a brand new 2018 Mazda 3 Hatchback Touring Modelwith an automatic transmission.

Yes, I know, a performance aftermarket parts company has an automatic; I’m right there with you, but there’s a good reason for it.  CorkSport has a couple Mazda3 6-Speed Manuals and a couple manual and automatic Mazda 6’s, but no automatic Mazda 3; so it made sense to add that to the garage, especially with the many new performance parts we have in the pipe line.  Check those out here.

Now back to the CorkSport’s new 2018 Mazda 3.

The 6-speed automatic comes equipped with three transmission control modes; Standard (default), Sport, and Manual (aka manumatic).

We became curious about how those three modes affected the driving experience, specifically the shift points. I believe we all understand how the Manual control mode works, as it provides nearly 100% control of the shift points, so for the comparison I am going to focus on the differences between the Standard and Sport modes since those are controlled by the ECU.  

Driving the car on the street, you can easily feel the difference between the Standard and Sport modes of the Mazda3.

The Standard mode feels soft, relaxed, and maybe even lazy between shifts. It seems to default to the highest gear (lowest engine RPM) possible in every driving situation. This is great for fuel economy, but disappointing for smiles-per-gallon.  Push the Sport toggle, and the car comes alive.  The engine pulls through the RPM range longer for each gear and seems more eager to accelerate with the slightest throttle input. MUCH better.

The Butt Dyno is great and all, but it’s subjective, so we decided to strap the car down on the dyno to see what is happening; what exactly is changing between the Standard and Sport modes with the CorkSport 2018 Mazda3.

On the dyno, things become much clearer, but first, we had to set up the dyno to provide us with useful information. Typically we are testing wheel Torque and Horsepower, not shift points. It was interesting to play with the various parameters the dyno has available to find a readout that would convey the shift points and the effort the car was exerting. Check out the graph below; this is not your typical dyno plot.

With this dyno plot we quickly see that is much different than the typical readout.  I’m going to break it down, so it’s clear and easy for you to understand what is going on.

Description: Standard Mode = Red, Sport Mode = Green

The horizontal axis is our independent variable in the test. This is the variable/parameter we can control directly in the test. Since we are trying to understand the difference in shift points between the Standard and Sport modes, Road Speed was the logical choice. To be consistent, the throttle input percent for both Standard and Sport modes was held constant throughout the test runs.

The two vertical axis’s are the dependent variables in the test; these are the parameters that depend on engine RPM. On the right side of the dyno plot, we have engine RPM; this is represented by the lines with dots. On the left side of the dyno plot, we have tractive effort, which is essentially the amount of force the tires are applying to the road surface.

Looking at the two graphs, it’s clear that the Sport mode shift points and tractive effort are much different than Standard mode. This is interesting because we can now visualize what we were feeling while driving the Mazda 3 Hatchback on the street.

In Sport mode, the car carries through the engine RPM longer, and the resulting RPM after each shift is also higher.  Because each gear is carried to a higher RPM the resulting power is much greater, which is shown with the tractive effort plots.

Finishing statement: Sport mode significantly changes the way the car drives and responds. If you are looking for some fun out in the curves, don’t be shy, hit that Sport toggle and let the Mazda do what it was designed to do best.

Happy driving!

What’s in the Pipeline for the 2014+ Mazda3?

Here at CorkSport, we are always working toward the next new product. We create our catalog just like you build your cars. Since there’s so much in development, we thought we would give you all a glimpse into what’s coming for the 2014+ GEN3 Mazda 3.

2.5L SkyActiv-G Turbo Kit

Let’s start with the big one since you’ve all been asking for updates: the 2.5 Liter Skyactive Turbo Kit. We are still making steady progress and are more excited than ever for this Mazda3 Turbo. Our functional turbo kit prototypes are slowly starting to arrive, meaning we are inching closer and closer to having our Mazda3 test car on the dyno (with added turbo noises). Stay tuned folks; this is going to be a fun one!

2014-2016 Mazda 3/6/CX-5 Motor Mounts

 

We already showed you the new and improved CorkSport Rear Motor Mount, but there’s more to come with the CorkSport Transmission Motor Mount. Check out the CAD model above to see what we’re talking about. Keep tabs on the CS blog for more info on the design and function of this motor mount soon.

2014-2016 Mazda 3 Skid Tray

The CorkSport skid trays have been consistently requested for the Mazdaspeed models; so much, that we brought them back for both the Mazdaspeed3 and the Mazdaspeed6. Now we are providing the same benefits to Mazda3 owners. We just received and test fit our first prototype skidplate, and it’s looking very promising moving forward.

2014+ Mazda 3 Suspension Kit

Need some extra handling and style for your Mazda3 but don’t want the hassle of lowering springs? We have created a kit that includes the CorkSport lowering springs, adjustable shocks/struts, and camber plates all assembled with OE accessories and ready to install. No spring compressors needed, for ease of installation. Coming soon…

2014+ Mazda 3 Front Sway Bar

Reducing overall roll or “sway” can drastically change your Mazda’s handling characteristics. We should be receiving our first prototype to test fit on our Mazda3 any day now are excited to see how it complements the CorkSport rear sway bar. Oh, and the new front sway bar is 3-way adjustable just like our ND Miata sway bars!

2014-2016 Mazda 3 Steering Wheel

Last, but not least, our leather steering wheel will be making a comeback in the coming months. Featuring a similar profile to the CorkSport Mazdaspeed3 steering wheels, it is designed to increase confidence in both aggressive and daily driving while staying comfortable and stylish.

As you can see, we are staying busy with the newest generations of Mazda here at CorkSport, but that doesn’t mean it’s the only thing we are focused on.

We still have plenty of upcoming products for you Mazdaspeed guys and gals, and for some platforms you may not be expecting. Keep tabs on the CS blog, Instagram and Facebook page to make sure you don’t miss anything!

Until next time,

-Daniel @ CorkSport
