This is what a 1,200-hp twin-turbo 4-rotor looks like in a Miata

The engine bay of drifter

We’ve seen the diminutive Mazda MX-5 Miata swallow plenty of big engines, but New Zealand drifting ace “Mad Mike” Whiddett is roaring into where-no-man-has-gone-before territory. Wanting to replace his 515-horsepower “MADBUL” RX-7 and its twin-turbocharged, three-rotor 20B engine, his new ride is an NC-series Miata with four rotors and twin Garrett turbochargers courtesy of Pulse Performance Race Engineering. It is called “RADBUL,” and expected power at standard boost is 1,200 hp, but the builders at Pulse Performance think it will get up to 1,500 hp at full boost. And yes, that exhaust exits through the hood.

Four-rotor engines are actually popular – builds are detailed on forums like this one from 2007 and this one from 2008, this UK company or this Canadian company will sell you one complete – but they’re usually being prepped for an RX-7. Mad Mike’s choice of a Miata for this enterprise makes this about as extreme as you can get, short of throwing it into a Mazda R360. You can watch Mad Mike tell the story of the build in the video, and check out the first and second installments about the build on the Red Bull site.

Mazda CEO closes door on talk of RX sports car revival

Mazda RX-7

Some rumors in the auto industry simply refuse to die. Over the last decade, a few of the strongest have focused on Japan. A few years ago, we could have explained away the constant whispering over a new Toyota Supra, Acura NSX or Mazda RX-7 as nostalgia for Japan’s golden era of performance. Today, though is different.

We already have the Nissan GT-R, and, thanks to the Toyota FT-1 Concept, a Supra successor finally appears to be on the way. Acura will someday, allegedly, deliver on its promise to put the NSX on sale. So where does that leave the third member of the Japanese performance trio mentioned above? Well, um, it still isn’t happening.

We don’t have that kind of vehicle in our future product plan,” Mazda CEO Masamichi Kogai told Automotive News when asked about a successor to the rotary-powered RX line. “If you increase the number of segments, then the resources we can allocate to each will decline and that will prevent us from developing truly good products.”

Kogai’s planning, according to AN, sees Mazda focusing more on its increasingly strong, efficient mainstream lineup, rather than its iconic sports cars, owing to its limited spending money.

“It’s difficult for us at present to further expand our lineup,” Kogai told Automotive News. “The company is still in the process of improving its financial structure. We want to focus our limited resources on the Skyactiv products that we have today.”

While enthusiasts may lament this move, analysts in Japan seem quite pleased with it. “A brand this size needs only so many poster cars,” Kurt Sanger, an analyst with Deutsche Securities Japan, told AN.

Do you agree? Should the growing proliferation of performance vehicles, particularly Japanese brands, push Mazda back towards a rotary sports car? Have your say in Comments.

Red Bull RX-7 goes drift crazy on New Zealand’s Crown Range

Red Bull Crown Range drifting by Mad Mike

For the first time ever, the Crown Range, New Zealand’s highest paved road, was closed off for the drifting pleasure of one man. That man is Mad Mike Whiddett, and the machine he’s piloting is a heavily modified Mazda RX-7 sponsored by the energy-rich crew from Red Bull and powered by a 750-horsepower quad-rotor engine. There will be smoke. Lots and lots of smoke.

Mad Mike hits speeds in excess of 140 miles per hour over the course of the road’s six and a half miles, which boasts 47 individual corners at over 3,500 feet of elevation. Scroll down for all kinds of fire-belching, tire-squealing and smoke-inducing action. Or, as Mad Mike himself puts it, “A dream turned into reality.”

Mazda to revive RX-7 in… 2017?

There is a special place in our hearts reserved for the Mazda RX-7. Its screaming rotary engine made the ’80s and ’90s a time of high-revving fun. While Mazda continued the rotary with the four-door RX-8, the two are not the same car, and eventually the latter was phased out.

The Motor Report is the latest outlet to crank up the rumormill over a return to Wankel power and an RX sports car for the troubled Japanese brand. According to TMR, a rotary engine could come back – and so could the RX-7 nameplate – albeit not overnight. The return of the RX-7 is said to be set for 2017, and the source quoted is none other than Mazda sports car boss Nobuhiro Yamamoto.

Speaking with the press at a local launch of the updated MX-5 Miata, Yamamoto said the future RX-7 would have a curb weight close to that of the Toyota GT 86 (about 2,600 pounds), and have a larger emphasis on the driver’s involvement. Yamamoto was also the powertrain chief for the JDM-market FD3S generation (1992-2002 model) and was extremely proud of that engine. Yamamoto reportedly says he would prefer a naturally aspirated version of that engine over any kind of forced induction solution, claiming that the 16X rotary engine that has been developed would be capable of 220kW (295 hp) in that configuration. The 16X was developed in 2007 but has yet to find its way into a production vehicle.

2017 would mark the 50th anniversary of the introduction of the rotary engine. Frankly, it would be a shame if some form of the quirky and revvy powerplant was not found under the hood of a sports car anywhere in the market.
