The 33% Faster, 50% Smaller, 100% More Innovative CorkSport Bypass Valve

The CorkSport Mazdaspeed MZR Bypass Valve (Patent Pending)

Mazdaspeed 3 BPV Upgrade

With the new Patent Pending CorkSport Mazdaspeed MZR Bypass Valve you can have all the goodies of an aftermarket Bypass Valve, in a smaller size. By using a unique patent pending wave spring design, CorkSport was able to shrink the body of our bypass valve to almost half the size of stock. Along with this, the wave spring was tested to respond 33% faster than a stock valve. Since the blow off valve is a safety feature to protect the turbo from premature wear, this increase in acceleration can help increase the longevity of the turbo and the system as a whole.

Lightweight components ensure quick response for the BOV for your Speed3

So why do you need to upgrade? Well, the stock Bypass Valve is pretty good, but it falls short in two areas. When it comes to holding boost the stock Bypass Valve often will start leaking at anywhere upwards of 17psi. If you plan on having your boost much higher than stock you could have issues with leaks. Of course, you also upgrade a bypass valve to get that unique sound.

While the unique patent pending CorkSport Mazdaspeed MZR Bypass Valve will provide both a unique sound and hold more boost, our BPV will also provide some other key benefits that, until now, have been pretty much ignored by others.

The CorkSport MZR Bypass valve utilizes a compact wave style spring which allows the stock valve size to be decreased by half. This patent pending design allows room for other engine upgrades such as Big Intakes, Airboxes, Front Mount Intercooler setups and more. Using a wave style spring that is 20mm in height compared to the stock 40mm not only enabled us to shrink the overall size of the valve, but also shrinks response time to lightning quick speeds. Though both the stock spring and our wave spring provide the same force and move the same distance before coil-bind, a smaller wave style spring can respond up to 33% faster.

A smaller spring allowed us to decrease the overall size of the piston while still pushing the piston area out to ensure a larger venting area. This reduces the time it takes to vent air and allows any turbo, especially larger turbos, to vent more efficiently.

No matter which benefit is more important to you, whether you value long turbo life, unique sound, more engine space, or holding higher boost, the CorkSport Mazdaspeed MZR Bypass Valve should be your first choice.

Fuel Pump Comparison Part 4 (Bombs Away!)

We know by now that adding power to your Mazda is fairly straightforward up to a certain point. However, sooner or later, that hunger for power means you’re going to need to step up to a new fuel pump that can flow more fuel. By seeing that most of the fuel pumps on the market were largely the same, we decided to see what kind of innovations we could bring to the table. At this point we had learned volumes about the pumps on the market through our research and decided to engineer a new set of pump internals that focused on everything that we had learned.

We know this is possibly the worst kept secret since Area 51, but we started engineering fuel pump internals over 2 years ago and we aim to show you why ours is worth the wait.

We didn’t just set out to make another pump; the market has plenty of those. We set out to make the best Mazda fuel pump upgrade on the market specifically for Mazdas from a company that ONLY makes parts for Mazdas.

We started by researching many different technologies and engineering ideas in the pressure ranges experienced in these fuel pumps. We purchased every kit on the market and a brand new replacement from Mazda to test. The results from some of those tests can be found here (Link to blogs 1,2, and 3). After agreeing that 9.8mm was the maximum size we could attempt for the piston without making the sleeve wall too thin, we could start engineering the rest of the part.

We then built all the internals available in SolidWorks and tested the efficiency of them all for flow design and volume. This was merely the beginning of our design phase but helped us realize many great ideas (as well as a few not so great ones). We ended up with a design unlike any other on the market that, according to the data, would be more efficient than anything on the market.

With the increase in flow and efficiency we knew that our design could also benefit from a stiffer spring rate for the pump. That would enable higher RPM’s and improved cam wear over the life of the pump. Since we would be flowing more, the pressure on the pump would be greater than ever, the stiffer spring was just good insurance to get the power we needed even past the stock redline.

During our testing we also discovered the keeper assembly used by the factory is no accident. Many of the other pumps on the market use a keeper system similar to an intake or exhaust valve. This style does a fantastic job of locking the piston in place, but creates a few issues of its own. Because of the flow of fuel, the piston rides one side of the sleeve more than the other; over time, this will wear more into the piston which will affect clearances and efficiency. To prevent this, the factory style keeper allows the piston to spin as the spring moves up and down. That led us to choose the factory style retainer. We didn’t want to guess on either design without proof of our theory so we produced samples of both styles to prove wear differences and address installation challenges related to both styles.

Now that the cat is out of the bag, we’ll have just one more fuel pump blog next week with a very exciting limited offer. Stay tuned as CorkSport is about to take Mazda performance one step higher!

CorkSport in the Blood!!!

Our own sponsored driver Matt Kellogg sent us a Top 5 list of the reasons he loves being sponsored by CorkSport and we wanted to share those with you because Matt started out much like many of you and has grown to be a true part of our family here at CorkSport.

Top 5 Reasons Why I love Being a Corksport Sponsored Driver

By: Matt Kellogg

It’s a passion of mine….import cars. To sum it up in a simple write-up or blog post is literally impossible. There are very few things in life that strike me the way import cars have. I have had my fleeting moments with various hobbies and some of them have stayed with me through the years while others have passed quietly by the wayside. Passion is what drives anyone to do what they do with fervor….this is my #1 reason for enjoying being a CS driver.
Art. You may say to yourself; “Art? Why would art have anything to do with this?” Easy! Art is in everything, but many do not see it nor realize it. Art is in the way we see the aesthetic aspects as good or horrible. Art is the way we drive our vehicles, a style if you will. Art is also in manufacturing and quality or such. Art in my instance is from birth and has played a major role in how I see the world and how I see what fits, and what doesn’t, this has given me the skills I have today and the future ones that I will continue to hone and learn.
Love of the sport. Same as “love of the game” for an athlete. Being a sponsored driver is much like being a sponsored athlete. How you handle yourself and your car not only reflects on you but the sponsor and all prospective customers and fans past, present and future. Loving what you do and caring about those who give you their helping hand to do it is a very important part of being an enthusiast and standing apart from the paper tigers of this ball we all spin on.
Dedication with reward. By this I mean, I am dedicated, sponsored or not when I find a company who not only cares about the customer, but cares as much for quality and dynamic release of great products I am excited and feel like a kid with a lollypop! Dedication is not only my goal and the key to success the company you work for, are sponsored by or just plain buy your products from must have a positive attitude to the sport, art, love and dedication aspects of it all. Without dedication we are mere lemmings marching to our cliffs.
The best part of being a CorkSport sponsored driver is the fact that my pride in what I do to my car is rewarded with the pride of CorkSport by taking the time to see me out here in the ocean of other drivers and see that I am dedicated to the sport, and always striving to do better and achieve higher standards with my vehicle. Much the same as CorkSport does on a daily basis. Thank you for reading my snapshot of what it means to me to be a Corksport driver!
