Kraftwerks Supercharger Kit
2013–2016 Scion FR-S, 2017–2020 Toyota 86, 2013–2020 Subaru BRZ
150-12-3300
Overview:
The Kraftwerks Supercharger Kit is a high-performance forced induction system designed specifically for the Scion FR-S (2013–2016), Toyota 86 (2017–2020), and Subaru BRZ (2013–2020). This tuner-focused kit enhances engine output by delivering significant horsepower gains while maintaining reliability and drivability. Featuring the proven Rotrex C30-94 supercharger, this system offers a smooth and linear power increase across the entire RPM range, making it an ideal upgrade for enthusiasts seeking improved throttle response and acceleration without compromising daily usability.
Engineered as a bolt-on solution, the kit is designed for ease of installation with no cutting, drilling, or welding required. It is important to note that this kit is sold as a tuner kit only and does not include fuel or engine management components, allowing users to customize their tuning setup according to their performance goals.
Key Features:
The Kraftwerks Supercharger Kit combines advanced engineering and quality components to deliver reliable power gains and efficient operation:
- Rotrex C30-94 Supercharger Unit: Ultra-high efficiency with silent operation and low operating temperatures.
- Self-Contained Lubrication and Cooling: Ensures high reliability and consistent performance under demanding conditions.
- Independent Drive System: The supercharger is driven by its own belt, separate from engine accessories, enhancing reliability and preventing engine accessory failure from affecting the supercharger.
- Toothed Belt System: Zero slip under heavy loads and accelerations, with low belt tension to reduce wear on the supercharger’s nose bearing.
- Offset Supercharger Placement: Allows for improved clearance around belts and a more efficient, clean tubing layout without awkward hoses.
- Cold Air Intake Location: Positioned in front of the radiator within the front bumper’s cold air section, delivering intake air temperatures at least 20°F cooler than under-hood setups.
- Optimized Tubing and Intercooler: Mandrel-bent aluminum tubing and an 11-row high-efficiency intercooler reduce intake air temperatures and support up to 460 wheel horsepower.
- Upgradeable Design: Dual bolt patterns on the mounting plate allow for easy upgrades to larger Rotrex supercharger units capable of up to 700 bhp.
- High-Quality MAP Sensor Included: Facilitates precise speed density tuning conversions.
Construction & Design:
The Kraftwerks Supercharger Kit is built with premium materials and engineered for durability and performance. The core Rotrex C30-94 supercharger uses patented traction drive technology, which transmits power through friction forces between rolling elements, resulting in smooth and efficient operation. The system’s mandrel-bent aluminum tubing ensures optimal airflow with minimal restrictions, while the large 11-row intercooler effectively reduces intake air temperatures to maximize power and prevent heat soak.
The independent drive system and offset placement of the supercharger allow for a clean engine bay layout and reduce mechanical stress on components, contributing to long-term reliability. The kit’s design also prioritizes ease of maintenance and upgradeability, making it a versatile choice for enthusiasts.
Performance & Sound
At a moderate boost level of 9 psi, this supercharger kit delivers approximately +80 wheel horsepower on 91-octane fuel using the OEM headers and exhaust. When paired with E85 fuel and upgraded Skunk2 headers and exhaust, power gains can reach up to +125 wheel horsepower. The power delivery is notably linear and smooth throughout the entire power band, enhancing drivability and traction. The supercharger operates quietly, maintaining a refined engine sound without excessive whine or drone, making it suitable for both street and spirited driving.
Installation & Fitment:
The Kraftwerks Supercharger Kit is designed for a straightforward bolt-on installation with an estimated install time of approximately 4.5 hours. No cutting, drilling, or welding is required, preserving the integrity of the vehicle. The kit fits the following vehicles:
- Scion FR-S (2013–2016)
- Toyota 86 (2017–2020)
- Subaru BRZ (2013–2020)
Because the supercharger uses an independent drive belt, installation does not interfere with the vehicle’s accessory belts, reducing the risk of accessory failure and simplifying maintenance. Professional tuning is recommended to optimize engine management and fuel delivery for the best performance and reliability.
