According to Motoring.com.au and an “insider” they have some new information on the next RX-7.
So what are the interesting facts they supposedly have heard?
1. Mazda is going to use a twin-scroll turbo setup with power near 450 hp.
2. Mazda will no longer use the MX-5 platform as a base.
3. Mazda has registered both RX-7 and RX-9 as names with Japan’s trademark office.
4. Mazda plans to celebrate their first Rotary powered cars 50th birthday in May of 2017 with the release of their new RX-7 or RX-9.
So what do you think? Does Motoring.com.au really have an insider in Mazda realizing this information? Or is it all just more speculation and made up rumors?
The CorkSport single-exit cat-back exhaust has been designed to replace your entire exhaust system from after your catalyst with a straight-through pipe to minimize exhaust restrictions and provide a deeper tone.
It features mandrel bent, TIG welded 80mm piping for a smooth flow and clean solid connections. The corrosion-resistant T304 polished Stainless Steel construction and 100mm Stainless Steel tip ensures a long life and provide a polished aftermarket look to your exhaust system. Also a weight savings of 22 lbs over the factory OEM system.
I have been getting more and more excited about the Mazda Skyactiv Diesel engines which are due to arrive in North America this spring. My thoughts have been a bit skewed with estimating power numbers with down-pipes, cranking up the boost, and doing crazy low RPM burnouts in the first 4 gears with mountains of torque. My dreams were dealt a big blow yesterday as the news was released by Mazda that the diesels have been delayed. Again.
Seeking an answer as to why the holdup I went to look at Mazda’s official press release. The Mazda official text is below
“Mazda North American Operations today announced that the launch of its SKYACTIV-D clean diesel engine in North America is being further delayed from its Spring 2014 announced debut timing.
While Mazda understands its SKYACTIV-D can meet emission regulation requirements without the use of a NOx after-treatment system, it was decided that further development is required to deliver the right balance between fuel economy and Mazda-appropriate driving performance.”
I read this as Mazda wants to make sure the car is trouble free for North America and I am giving them props for this. In the rest of the planet people are more familiar with diesels and the needed upkeep with urea injections to keep NOx lower. Mazda is trying to do away with the need for this completely making the car similar to owning a standard petrol powered car which I am in agreement with. Your average American is used to a diesel in an F350 or a Dodge not a passenger car and the last thing you want is people having problems with their cars and posting to Yelp about it for not understanding the real issue.
So for now my burnout dreams will be just that, dreams until Mazda gets it all sorted out. I wonder if they would let me take one of the 25 hours of thunder hill cars for a weekend to hold me over…

Who Wants The SKYACTIV-D? September 11th, 2017CorkSport
The CorkSport Mazdaspeed MZR Bypass Valve (Patent Pending)
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. For more about all the innovations in the CorkSport bypass valve, click here.
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.
Our very own CorkSport sponsored driver Matt Kellogg was featured in the news in his home state of Texas for his help with honoring wounded warriors. We’ve known for a while how special Matt is and we think it’s fantastic that he is getting some more exposure for his cause. But enough of our bragging about him, check out the video below and get just a glimpse of what we’ve seen from him.
Thanks again to Matt for his service to his country and to others in need!
