Rob Dahm has built a Mazda MX-5 Miata with a single-rotor Wankel engine, turbocharged to produce 155 hp. The new video shows the engine running on the dyno with a distinctive rotary sound that enthusiasts will love.
In a unique engineering project, Rob Dahm has successfully built a Mazda Miata (MX-5) with a single-rotor rotary engine equipped with a turbocharger, producing 155 horsepower. The new video shows the engine running on the dyno with an incredible sound. Rotary engine enthusiasts are in for a completely new experience.
What is the story behind this rotary Miata?
The project is not just a simple modification but a complete build from scratch. The single-rotor engine is made from billet aluminum, a very rare design in the modified car world. Rob Dahm, who has thousands of followers on YouTube, posted a video documenting the engine’s first start on the dyno, showing torque and a sound reminiscent of traditional rotary engines but in a smaller package.
Why a single-rotor engine?
Traditional rotary engines (like the Wankel) usually have two or three rotors. Using a single rotor reduces weight and complexity while maintaining the signature sound. The turbocharger boosts power to compensate for the small displacement, resulting in 155 hp – an impressive number for a lightweight car like the Miata.
How much power does the engine produce?
According to The Drive, the engine produces 155 hp at the crankshaft. Acceleration figures have not been released yet, but thanks to the Miata’s light weight (around 1,000 kg), performance is expected to be exciting. The dyno video shows quick throttle response.
Is this project production-ready?
Rob Dahm has not announced any intention to turn the project into a commercial product. However, it proves that rotary engines are still alive in the tuning world. The project is aimed at fans of unique engineering sounds and may inspire others to undertake similar experiments.
When can we see the car on the road?
So far, the engine runs only on the dyno. No transmission has been installed, and no driving tests have been conducted. But Rob Dahm is known for completing his projects, so we may see the rotary Miata driving soon.
What do car enthusiasts in the Gulf think?
In Saudi Arabia and the UAE, Japanese car modification culture is widespread, especially for Mazda. This project may attract significant interest from rotary fans, even though rotary engines are rare in the region due to maintenance challenges. However, the sound and light weight may tempt some to try a similar build.
Frequently Asked Questions
What is a single-rotor rotary engine?
It is a Wankel rotary engine with only one rotor instead of two or three. It features a unique sound and light weight, but needs a turbocharger to compensate for small displacement.
How much power does the rotary Miata make?
It produces 155 hp thanks to a turbocharger, making it potent for a lightweight car like the Miata.
Will this car be available for sale?
No, the project is for hobby and experimentation only. Rob Dahm has not announced any commercial plans.
