Are you familiar with the Mazzei Formula Five yet? I’ve detailed the remarkable creation several times for this esteemed site. Essentially, it’s a custom-built five-rotor supercar featuring a brilliantly engineered chassis encased in a Superlite SL-C kit car body. Last time we checked, the single-seater had just produced 1,120 wheel horsepower on the dyno. However, that was with a 106-millimeter turbo, which has now been replaced by something even more powerful: A 119mm turbine that’s bound to scream even more.
David Mazzei, the creative force behind this project, is venturing into new realms as he sent his Garrett G57 turbo to Forced Induction Systems for a revamp. They upgraded the unit with their own cast housing and what Mazzei described as a “7+7 splitter blade.” Thanks to these enhancements, they now have approximately 30% more surface area than previously, allowing the turbo to move around 30% more cubic feet of air per minute at similar boost levels.
While this setup could certainly accommodate more power than before, that’s not the principal aim. Mazzei hopes to reduce exhaust gas temperatures while improving volumetric efficiency beyond 8,000 rpm; with the 106mm turbo, the power curve significantly dropped past that threshold. It seems the compressor wheel of the former power-adder was spinning so rapidly that it couldn’t effectively move any extra air at high RPMs.
To ensure reliability, he also fitted an exhaust manifold back pressure sensor, an additional sensor right before the throttle body to check if it’s backing up the turbo’s compressor, and a boost gauge after the intercooler core to monitor pressure drops across the unit.
In his latest video, Mazzei has openly acknowledged several times that the car doesn’t require more speed for him to enjoy it. While “sensible” might not be the right term—after all, he constructed a five-rotor supercar from scratch. Nonetheless, he elaborated that he will continue to explore this build to see what’s achievable, as he’s attracting numerous tuning clients along the way.
Nonetheless, Mazzei is still making some modifications simply for enjoyment. Daddy Turbos crafted a T-51R mod for the enlarged super-spooler, mimicking the incredible whistle from one of the legendary Japanese tuner HKS’s discontinued models. It’s nearly guaranteed to be the world’s largest of its type.
I’m quite fascinated by this project as Mazzei persistently discovers new ways to elevate its extremity. He accomplishes this in such a manner that it’s not merely about maximizing YouTube views. Instead, he’s authentically employing the car as a testbed to learn and uncover new insights for rotary platforms. One thing is certain—he is well-versed in peripheral port mechanics.

### The Advantages of Implementing a 119mm Turbo on a Five-Rotor Supercar
In the domain of high-performance automotive development, the pursuit of power and efficiency frequently drives enthusiasts to investigate advanced turbocharging options. One such solution is the integration of a 119mm turbocharger on a five-rotor supercar. This amalgamation can yield considerable advantages, enhancing both performance and driving enjoyment.
#### 1. Elevated Power Output
One of the most persuasive benefits of a 119mm turbocharger is its potential to significantly boost the power output of a five-rotor engine. The increased compressor and turbine dimensions facilitate improved airflow, enabling the engine to generate more horsepower and torque. This is especially advantageous for supercars, where performance is critical. The added power can lead to faster acceleration and higher top speeds, enhancing the vehicle’s competitiveness on both the road and track.
#### 2. Enhanced Efficiency
While larger turbos are often linked to increased power, they can also aid in enhancing engine efficiency. A 119mm turbo can fine-tune the air-fuel mixture, enabling the engine to function more efficiently at elevated RPMs. This can translate to improved fuel economy, particularly during high-performance driving scenarios. The capability to derive more power from the same volume of fuel is a notable advantage for supercar aficionados seeking to strike a balance between performance and practicality.
#### 3. Better Boost Response
The configuration of a 119mm turbocharger can result in improved boost response, essential for driving dynamics. A well-calibrated turbo can minimize turbo lag, allowing the engine to provide power more promptly when throttle is engaged. This enhanced responsiveness enriches the driving experience, making the vehicle feel more nimble and in tune with the driver’s inputs. For a five-rotor engine, renowned for its distinctive power delivery characteristics, this can lead to an exhilarating driving experience.
#### 4. Customization and Tuning Opportunities
Integrating a 119mm turbo on a five-rotor supercar opens up vast customization and tuning opportunities. Enthusiasts can adjust their engines to meet precise performance objectives, whether that’s maximizing horsepower for track purposes or optimizing for daily driving. The larger turbo permits a wider array of tuning options, empowering builders to customize the vehicle’s performance traits to suit their preferences.
#### 5. Distinctive Sound and Character
The auditory experience of a five-rotor engine paired with a 119mm turbo is a unique feature that resonates with many automotive enthusiasts. The combination generates a distinct sound that distinguishes the vehicle from others on the road. The turbo’s spool and the engine’s rotary nature create a sound that is both thrilling and unforgettable, enriching the overall pleasure of operating the supercar.
#### 6. Competitive Advantage
In the arena of supercars, having a competitive advantage is vital. The integration of a 119mm turbo can provide that edge, allowing the vehicle to outperform its peers in its class. Whether on the racetrack or during spirited drives, the extra power and responsiveness can substantially affect lap times and overall performance metrics. This competitive edge can be particularly attractive for individuals involved in motorsports or track events.
#### Conclusion
The addition of a 119mm turbo on a five-rotor supercar presents multiple advantages, ranging from elevated power and efficiency to better boost response and distinctive sound. For automotive enthusiasts eager to push performance boundaries, this combination represents an enticing option that can elevate the driving experience to unprecedented heights. As technology continues to evolve, the possibilities for turbocharging and performance tuning will only broaden, making it an exhilarating time for supercar enthusiasts.
