Kawasaki’s STX 15F Supercharged 330HP
Staff
 

It was reported earlier this year on JetSki.com That Kawasaki had a Supercharged 15F. Well it is true and Kawasaki debuted it at the 2004 JetSki World Finals on Friday .It claimed with ease, the World Championship in the Pro Am Runabout Modified class with Dustin Farthing aboard.

Although no confirmation on if this will be in the line up next year, Our sources say that the public wants it and it would be a logical fit to go up against the Sea Doo RXP (it would fit in that class head to head). We have been notified of something new coming from Kawasaki but that is all Kawasaki would say. They would not confirm if this is the model they are talking about or NOT?

This Supercharged 15F looks Mean and  is a real fire breather, pumping out 330 HP on the Dyno. Yes I did say 330 HP? Which is more then a lot of hot rods put out. And with the Horsepower to weight ratio, you don’t have to be a gear head to figure out, its FASST.

Joe Hiem , Kawasaki Team Manager says that this Supercharged 15F is basically stock which tells you the 15F has a good 4 stroke engine from the get go. Hiem says that they added a Vortech Supercharger, which the Vortech superchargers systems are developed to achieve maximum performance, efficiency, and durability. Impellers are investment cast from a lightweight proprietary aluminum alloy, heat treated, CNC machined to exact tolerances and the high speed balance to ensure smooth operation. Gearcases and volutes are cast from premium A356 aluminum alloy, heat treated, and CNC machined to ensure production consistency. Most models feature our exclusive "D" port volute for improved efficiency. Drive gears are manufactured from premium billet alloy steel, heat treated, precision ground on automated CNC machines to aircraft tolerances, and engineered to operate at speeds exceeding 70,000 RPM. Bearings are made in America to our precision tolerances. An O-ring compressor housing seal and an innovative impeller seal improve sealing, reduce friction, and allow upstream throttle or draw through use. High pressure engine oil is used for cooling, lubrication, and very low maintenance.


Joe Hiem also say's, they are using the Vortech intercooler: Vortech charge coolers feature a dual pass liquid-to-air configuration, which features a closed loop water cooling system with a stand-alone pump, tank and front mounted heat exchanger.

Joe also added that they are running 13lbs of boost.

Joe Hiem tells us that they went with the MTC Forged pistons and lowered the compression to compensate the Supercharger.

These parts you can get and add to your 15F. But Joe also said they are running a modified ECU which the public cant buy at this time. But if you could buy it and add it with this Combo your 15F will make an impressive 330HP according to Kawasaki Team Manager Joe Hiem.

Joe Hiem say’s to put the power to the water they run a Skat Trak pump and impeller.
