Small Packages: The Future of Big Power From Small Displacement Engines
Tucked into my dresser drawer is a t-shirt with the words “No replacement for displacement” printed on it. A little discolored from years of washes, it was given to me back in my Personal Watercraft Illustrated days; a gift from Yamaha around the same time the Super High Output (SHO) 1,812cc engine was introduced. The late 2008 introduction of the big 1.8 liter engine to the personal watercraft industry was a historic one. Although the factory tune produced a meager 218-horsepower, the potential buried within the engine was easily unearthed.
I remember the impact well. Factory Yamaha racer Mike Follmer was one of the firsts to clock some serious speed. Working alongside R&D Performance’s Bill Chapin, Follmer’s red, white and blue FZR tripped the radar gun at 81mph with the use of a Motec ECM, a larger intercooler and supercharger, open exhaust and a few other Open class modifications. Together with Bill and Motec’s Pete Swinney, we recreated the same build with a black-and-gray FZS over two blistering hot days of testing and wrenching at Lake Havasu’s Body Beach.

I am glad you mentioned the axial drive engine. Most have no idea it exist. funny thing is this has been around for over 10 years. Rotax and Weber are good examples. It is only now becomming popular as fuel prices soar.
