Video: FuelTech CEO Details How to Compound Boost a Yamaha SVHO Over 1,450HP

For those who managed to catch The Watercraft Journal IRL podcast where we welcomed FuelTech CEO Anderson Dick and Greenhulk Garage’s Greg Gaddis, you might’ve gathered that Anderson is not like contemporary tuners that we’ve got in the personal watercraft aftermarket.

Anderson’s penchant for devising simple solutions for seemingly complicated performance issues has resulted in massive breakthroughs in the top speed/racing arena. One such hurdle has been how to best maximize the boost (increased intake atmosphere) of a supercharged engine.

In the video below, Anderson details that the entirety of the current pool of HydroDrag participants are seeking these extraordinary horsepower numbers all wrong. Rather than radically re-engineering the engine for maximum power output (he uses a SVHO in this instance), he suggests leaving it be.

Rather, he details how building the engine for maximum longevity (superior oiling, fueling and durability) and force-feeding the supercharger through a compound turbo system allows the supercharger to operate within its “safe” parameters requiring no extra effort to generate added boost.

Instead, Anderson illustrates how the SVHO’s supercharger is a 2-to-1 multiplier; and when fed 10psi of boost, the supercharger compresses that intake charge to 20psi. Therefore, when fed 30psi from a Garrett turbo, the supercharger presses out an incredible 60-plus-psi, with minimal back pressure.

When paired with a FuelTech FT550 ECU and an electric blow-off valve, the combination can literally command boost on a whim. To quote Gaddis, “This is the future of performance PWC.” The video below is an incredibly detailed tutorial that will have many rethinking their current combinations.
