Designed with the most advanced simulation software, the TTR CNC Billet manifold for Yamaha 1.9L engines (from 2024 onwards) sets new standards. Featuring internal carbon fiber intake runners and a balanced plenum, it has been tested under extreme conditions on the FuelTech Compound (Turbo + Supercharged) jet-ski.
PRODUCT FEATURES
Reversible Design: The plenum can be mounted with the throttle body facing forward or backward, adapting to Turbo or Supercharger systems.
Extraordinary Efficiency: Impeccable airflow distribution. Tested with EGT at 1450°F, it maintains cylinder variance below 20°F, ensuring absolute thermal stability during racing.
Injector Flexibility: Designed for 4 or 8 injectors. Supports over 1000hp depending on the injectors chosen (FT Injectors recommended).
Throttle Body Options: Compatible with the original Yamaha (SVHO/HO), the 82.5mm cable-driven Ford, or the 68mm Bosch Motorsports (recommended choice).
Compatibility and Sealing: Compatible with OEM fuel rails for 4 injectors. For 8 injectors, the use of TTR High Flow Racing Fuel Rails is recommended. All flanges use O-rings for an airtight seal on the cylinder head, plenum, and throttle body.
