Title: Unleashing the Beast: The Insane Six-Rotor Mazda RX-7 Engine
Introduction
Mazda enthusiasts and car enthusiasts, in general, are no strangers to the power and performance of rotary engines. However, a company from New Zealand has taken the concept to a whole new level with their six-rotor engine for the iconic Mazda RX-7. This article explores the incredible capabilities of this engine and the impressive RX-7 project car it has been fitted into.
The Six-Rotor Engine: A Marvel of Engineering
The six-rotor engine developed by Pulse Performance is a true engineering marvel. Based on three 13B two-rotor engines, it boasts an array of custom features that make it a force to be reckoned with. The engine build includes a custom air intake and exhaust manifolds, upgraded fuel pump, regulators, and injectors, a bespoke wiring harness, and a wet sump oil system. With a price tag of NZ$117,800 (approximately $71,000 USD), this engine is not for the faint-hearted. Pulse Performance also offers other rotary engine packages, including a three-rotor unit for NZ$68,000 (~$41,500) and a quad-rotor engine for NZ$96,000 (~$58,600).
Unleashing the Power: The RX-7 Project Car
Humpries Steel & Performance, a local tuner in New Zealand, had the privilege of fitting the six-rotor engine into an RX-7 project car. This bespoke vehicle made its debut at New Zealand’s Rotary Reunion track event earlier this year, leaving enthusiasts in awe of its power and performance. The entire chassis of the RX-7 had to be custom-built to accommodate the massive engine, along with specially designed suspension components.
A Symphony of Power: The Sound of the Six-Rotor Engine
One YouTuber, misfire, had the opportunity to witness the RX-7 project car in person and described it as an absolute animal. The high-revving nature of the six-rotor engine produces a sound that is otherworldly. It roars like a jet fighter taking off, creating an auditory experience unlike any other. The sheer power and intensity of the engine’s sound truly reflect the beast that lies within.
Performance Upgrades: Transmission and Brakes
To complement the immense power of the six-rotor engine, the RX-7 project car features an HGT Precision six-speed sequential transmission. This transmission allows for lightning-fast gear changes, maximizing the engine’s performance capabilities. Additionally, the car is equipped with a robust brake system sourced from Wilwood, ensuring optimal stopping power and control.
Bonus: Another Wild RX-7
In addition to the six-rotor RX-7 project car, we have included a bonus video featuring another wild RX-7, this time from Europe. This RX-7 retains its stock two-rotor Wankel engine but has been fitted with an aftermarket turbocharger, boosting its power output to an impressive 420 horsepower. Not only is this car incredibly fast, but it is also notorious for its deafening exhaust note. In fact, it was even banned from the Nurburgring after just a few laps due to its excessive noise levels.
Conclusion
The six-rotor Mazda RX-7 engine developed by Pulse Performance pushes the boundaries of what is possible with rotary engines. Its immense power and unique sound make it a true standout in the automotive world. The RX-7 project car fitted with this engine showcases the dedication and craftsmanship of Humpries Steel & Performance. These incredible machines serve as a testament to the passion and innovation that drives the automotive industry forward.
