Introducing Nizpro Marine’s Supercharger Upgrade Kit for Yamaha 6 cylinder 4.2l marine outboard engines. When development started a number of years ago, our aim was simple – to produce the most powerful 6 cylinder marine outboard on the planet. This goal has now been firmly achieved, but it’s not only the power that is impressive, but also the unparalleled value for money.
Please Note: Some aesthetic aspects of this kit have changed on the production version.
Direct-fit Supercharger Upgrade that takes only a few hours to install
Eaton TVS R1900 Twin Vortices Series (TVS) Rotating Assembly
450 HP from 5500 to 6200 rpm at 7 psi positive pressure
425 ft lbs at 5350 rpm
90% of engine torque available from 3000 to 6200 rpm
300 ft lbs at 1200 rpm
Adds only 55 lbs to existing F and VMAX Series engines
Power to weight ratio of between 0.75 -0.81 horsepower per pound
The most powerful 6 cylinder outboard marine engine on the planet
Harrop Engineering engaged for production – SAI GLOBAL certified ISO9001 quality since 1995
In 2008 Yamaha released their brand new Offshore and Super High Output series of outboard engines and dubbed them the “Game Changer”.
Compared to running two Yamaha 6 cylinder outboards, Nizpro Marine’s Supercharged 450s is 556 pounds lighter, no additional drag through water and no additional service costs.
Now THIS is the true “GAME CHANGER!”
Eaton TVS R1900 Features
Eaton’s new Twin Vortices Series (TVS) is a Roots-type supercharger for a variety of engine applications that delivers more power and better fuel economy in a smaller package, for uncompromising, high-performance driving
The TVS supercharger’s patented design features four-lobe rotors and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity, and enable higher operating speeds. The TVS supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a very wide operating range
The improvements incorporated into the TVS design allow for the use of a smaller supercharger, reducing the package size and weight of the system. The sizes range from 350cc to 2650cc per revolution, and cover engines from 0.6 liter up to large displacement V-engines. All TVS superchargers have a 2.4 pressure ratio capability and a thermal efficiency that exceeds 70 percent, which enables more compact packaging and greater output
The twin four-lobe rotors feature 160-degree twists. The higher helix angle of the rotors coupled with a redesigned inlet and outlet ports, improves the TVS’s air-handling characteristics without increasing the overall size of the unit. The TVS improved noise and vibration characteristics eliminate additional noise-reduction treatments, complexity and system cost
The TVS Roots supercharger sets a new standard of boosting device performance and reaffirms Eaton’s leadership in the performance marine market
