Zach’s Road to CorkSport

The Journey to CorkSport

Ever wonder what it was like to win the lottery. You ever let your mind wander and think what it would be like to actually “Live the dream.” I know I have, well, until I joined CorkSport! My name is Zach Sprague, and I wanted to share with you my experience of joining, what I believe to be, the best well known and respected company in the Mazda Community. Letโ€™s take a look at my journey.

I’ve always been into cars and have had a pretty big obsession with FWD Hatchbacks. My passion for this platform started back in 2014. I sold cars for Toyota in Southwest Washington for about four years. During my tenure, I drove some pretty amazing vehicles, one of them being a 2013 VRM MS3 Tech pack. I knew what a Mazdaspeed was, a Turbo FWD Hatchback, and at that time that was more than enough to pique my interest in the platform. It was temporarily sitting on my lot, and I had to drive it back down to Portland to our sister store.

Before jumping into the seat, I didn’t know any horsepower or torque figures. I didn’t know what kind of emotion it was going to spark when I drove it. I had NO idea that it would become the screen saver on my computer. I slid in and pushed the button. (You know those Cold Starts) This Mazdaspeed’s exhaust made my heart drop and gave me goosebumps. I honestly felt like an 8-year-old on Christmas Morning.ย 

Once on the ramp, I slowly shift into third at about three and a half grand on the tach and just sent it. Torque steer was prevalent as I was gently pushed back into my seat. I slammed 4th, and I hear this intoxicating PSSHHHHHH from the short ram intake. I was done, I was hooked, addicted and didn’t know what to do with myself. I was so intrigued I stopped at every rest stop on the way down so that I could feel this car accelerate back onto the freeway. <insert uncontrolled giggling here>.

Flash forward a couple of years, and a guy I worked with, now one of my best friends, went out and bought a VRM Mazdaspeed6. Everything on that car from top to bottom was stock down to the wheels. I slowly watched his build progress over the year and transform into one of the most inspiring builds I have ever seen. In that time he was kind enough to let me pick his brain about these cars and what they like, what they don’t like.

In 2018 this is when things got interesting! After a few months of looking and 100 YouTube videos later, I was finally ready to pull the trigger on one of my bucket list cars. I snagged a 2013 MazdaSpeed3 in liquid Silver. I drove almost 4 hours and paid an arm and a leg for sales tax, but it was worth it.

Miles of Smiles 

I was grinning ear to ear the entire way home; 4th gear dumps on the freeway, testing the grip of the tires out at a few stoplights, full-on shenanigans. I tell you what; I made it home a lot quicker than the drive up.  

I had the car for 3 weeks before I added my first mod. I already had a vision for the car, but first things first, I had to take care of those sloppy shifts. My shifter bushings and short shift plate showed up from CorkSport. At that time I knew they made great parts and were one of the very few places that even made parts for this car. What a difference that made! It felt robust and more responsive.

The Opportunity of a Lifetime

I always joked with my friends about working for a company like CorkSport. I just thought it was this elusive dream that I’d be sitting behind a desk helping other people build their dream cars. I never thought in my life that an opportunity like this would come into fruition. 

My buddy, who helped me get into Mazdaspeeds, sent me a message on FB, letting me know that CS was hiring. I thought to myself; this is no lie. “There is no way on god’s green earth I’d ever get that lucky.” However, I applied. What’s the worst thing that could happen, right? 

CorkSport isn’t a revolving door, and the team is made up of a close-knit group of professionals that also happen to be car nuts. They carefully consider who’s going to be a good fit with their existing team and identify candidates that are going to get the right shit done well. I knew this was a different company, and their standards were high because they didn’t just accept my resume; there was a pre-test.  

A funny little story. I got a message from CorkSport saying they wanted to set up a phone interview! I couldn’t believe it! That Friday, I called to set up a meeting for Monday. This is where the humor known as my life kicked in; I BROKE MY PHONE ON SUNDAY! *RED ALERT* My dream job was calling me on Monday, and I didn’t have a phone, so I went out and bought a little prepaid flip phone. 

Although I almost missed this opportunity, it went well enough for CorkSport to schedule a second interview over Skype. I must add, this occurred over two weeks. I was losing my mind; I couldn’t believe it was happening. All my buddies knew I had the job, they knew how obsessed I am with cars, especially my Mazdaspeed 3. I still was in shock couldn’t believe I had my second interview.

When CorkSport called me to let me know, I had a final interview with the Company’s President, Corey – Hello nervousness, glad to see you again! I can’t put into words how excited I was; it was pure bliss and absolute disbelief. “IS THIS REALLY HAPPENING!” I screamed at the top of my lungs when I got off the phone. I showed up a half-hour early. It was cool; I got to meet someone I’ve stalked on Instagram for a while and who has been a significant influence on me since I got into the Mazda community – Brett White.

It’s so surreal when you get an interview for a job you’ve always wanted. Above all, I remember from the interview is telling Corey, “Even if I don’t get the job, knowing I made it this far and am sitting here with you having this interview is honestly a dream come true.” It’s unreal to think that one mistake, such as breaking my phone the day before my first interview, could have kept me from writing this blog for a company I’ve looked up to since I’ve been into Mazda’s.

I cannot believe I’ve been here a little over a year already! It’s a fun environment where everyone is looking out for one another. I’ve been able to FLY in the fastest thing I’ve ever been in (Barett’s monster Gen Juan), and had the chance to drive a car I’ve drooled over on social media (Brettโ€™s Baby) for years.

Looking back, it wasn’t even four days after joining the company before the guys a CS put lowering springs on my car. It took a little over a week for me to buy an AccessPort and a Dual VTA Bypass Valve, and that was just the start! You don’t want to be an employee driving a stock Speed with a CorkSport Sticker on it.

Stay tuned to see where CorkSport and I go with my car. I’ll catch you on the flipside and, thanks for reading my first blog!

Easy and Accurate Boost Readings: The CorkSport Mazdaspeed 4.5Bar MAP Sensor

Mazdaspeed 3 4.5 bar MAP sensor

We are proud to introduce the release of a new product: the CorkSport Mazdaspeed 4.5Bar MAP Sensor for Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7 Turbo. Weโ€™ve had the CS 3.5 Bar MAP Sensor for a while now as itโ€™s a necessity when targeting over 21psi, however, while maxing out the CST6, we found the 35psi ceiling of the 3.5Bar sensor just wasnโ€™t enough. Enter the CS 4.5Bar MAP Sensor!

Mazdaspeed 3 4.5 bar MAP sensor

Before I get into explaining what makes this sensor tick, lets quickly go over what exactly a MAP sensor does on your Mazdaspeed. Manifold absolute pressure (MAP) sensors in a nutshell just read the pressure present in the intake manifold of your car. During normal driving conditions, the sensor is typically reading vacuum (or negative pressure) as the engine sucks in air. While in boost, the sensor reads the positive pressure (boost pressure) produced by your turbocharger. In both situations, this pressure reading is being sent to the ECU so the ECU understands exactly what the engine is doing.

The OEM sensor is a 2.5Bar unit, meaning it can do 1Bar of vacuum (negative pressure) leaving you only 1.5Bar (~21psi) before the sensor runs out of accuracy. Both the CS MAP Sensors allow you to accurately read boost levels higher than the stock sensor, so your tuner can target a higher boost pressure for more power, provided you have the right supporting mods. The sensors themselves do not increase your boost pressure, they simply enable your tuner to safely do so.

Enough learning, letโ€™s get into the 4.5Bar Sensor! The CorkSport 4.5Bar MAP Sensor can read a maximum boost pressure of ~48psi before it starts running out of accuracy. Having a huge potential boost pressure means nothing without a fast responding sensor, so we designed the CS 4.5Bar MAP Sensor to have near instantaneous response of only 2 milliseconds. This means if you have the build and turbocharger to do so, this sensor is ready for just about anything you want to throw at it.

A true plug in MAP sensor for your Mazdaspeed no adapter required

The CorkSport 4.5Bar MAP sensor uses a custom injection molded body that mimics the OEM sensor. This makes it a direct install into the OEM location and a direct plug into the OEM wiring harness. No wiring or adapter harness needed. This results in a clean install that takes as little as 15-30 minutes! 

Everything needed for installation is included with the CS 4.5Bar MAP sensor. A new mounting bolt is supplied to ensure everything stays put, while a fresh O-ring is attached to the sensor to provide a good seal in your intake manifold. To top it off, calibrating for the sensor is easy as the calibration for use with Cobb Accessport is laser etched right on the body of the sensor.

Oil Catch Can Kit for 2016+ SkyActiv Turbo 2.5L

Skyactiv Turbo OCC Kit

When you think of a performance aftermarket component you typically think of a part that increases the vehicleโ€™s power, but some performance parts donโ€™t. Instead, they have a more critical purpose, increasing the reliability of your performance engine and components.ย  The CorkSport Oil Catch Can Kit (OCC Kit) is just that type of component(s).ย 

CNC machined Mazda Oil Catch Can

Why is an Oil Catch Can Kit critical for your Mazda?  Despite the huge advancement Gasoline Direct Injection (GDI) technology there are still some downfalls.  Compared to the more conventional port injection fuel systems, GDI is much more prone to engine oil fuel dilution.  This is primarily due GDI injecting directly into the cylinder; in low speed operation and cold starts the fuel simply does not have enough time to fully atomize into a gas before ignition.  This results in some excess fuel seeping past the piston rings into the oil along with any combustion chamber blow by the pistons.  This is fuel dilution. 

OCC catch all the nasty build up from entering your Mazda Skyactiv engine

Here you can see the results of a CorkSport OCC installed for ~3000 miles on a 2018 Mazda 6 2.5T.ย  This engine only has 500 miles and has an average commute of 15 miles & 20 minutes of mixed traffic and speeds.ย 

Mazdaโ€™s OE design attempts to resolve some of this with a valve cover breather that vents directly into the turbocharger compressor inlet and a PCV (Positive Crankcase Ventilation) valve in the engine block that vents to the intake manifold. 

How the Mazda OCC works

Mazdaโ€™s setup depends on the fuel and water vapor inside the crankcase being drawn into the intake manifold and intake system to then be re-ingested by the engine.ย  This has two major flaws:

  1. The direct crankcase ventilation via the PCV valve only works while cruising (no boost).  Combustion gas blow by will occur most often while in boost under high throttle application when the PCV valve is closed.
  2. This forces the engine to re-ingest dirty air that carries contaminants in the form of fuel and water vapor along with carbon debris.  These containments then build up on the inside of the intake manifold, cylinder head runners, and the intake valves slowly degrading performance over time. 
Carbon build up on a Mazda engine without the catch can

The CorkSport OCC Kit provides you with two major features:

  1. Both the valve cover vent and the PCV valve are drawn from the turbo inlet directly ahead of the turbocharger compressor. Thus both the valve cover and PCV valve have constant vacuum in all driving conditions, both cruising and high throttle application.
  2. The oil catch can itself acts as a โ€œfilterโ€ for the vapor and debris that would normally be directly ingested by the engine. The drawn crankcase vapor and debris is separates and collects in the catch can for easy removal during normal oil changes. 

As you saw above, there is a significant amount of vapor and fine debris that is being filtered out of the crankcase air that would have normally been ingested.  As you continue down the path of modifying and demanding more form your Mazda, the need for a OCC System only becomes more and more critical.
