Meticulously designed using the most advanced simulation software, the TTR CNC Billet intake manifold for Yamaha 1800 jet-ski engines sets new performance standards. Featuring carbon fiber internal runners and a plenum design that maintains a perfectly balanced airflow distribution, this manifold has been tested and refined in extreme environments, including our FuelTech competition jet ski (Compound Turbo and Supercharged), a fundamental platform for innovation in water sports.
PRODUCT FEATURES
-
Incredible Efficiency: Even at extreme boost and RPM levels, this manifold has demonstrated extraordinary thermal stability. Acquired data shows an exhaust gas temperature (EGT) variance of less than 20°F over a 1450°F range: an impressive result even in the most demanding conditions.
-
Power Flexibility: Engineered for use with 4 injectors, it simplifies the fuel system, wiring, and overall complexity, leveraging the cutting-edge technology of our FT Injectors. It can be used with any injector based on the desired power and fuel, being capable of supporting over 1000hp.
-
Advanced Compatibility: The manifold integrates perfectly with traditional RIVA Racing or compatible fuel rails (the 11mm top feed may need to be drilled for the FT Injectors, not included). Sealed with supplied O-rings on all flanges, it ensures an airtight seal on the cylinder head, plenum assembly, and throttle body.
-
Throttle Body Options: Compatible with the original Yamaha electronic throttle body (SVHO or HO) or the professional favorite, the 68mm Bosch Motorsports unit.
-
Turbo-Specific Design: The throttle body is strategically positioned toward the rear of the jet-ski, ideal for turbo conversions, significantly reducing intercooler piping length and improving overall efficiency.
