PowerNow Info
The Scary Fast PowerNow provides bigger horsepower improvements, greater power at ¼ and ½ throttle for 2-strokes, 4-strokes, mini bikes and ATVs. Mounted into the backside/airboot side of the carburetor, the PowerNow, slices the single air venturi going into the carburetor into 2 smaller, faster, venturis via the PowerNow's 'Power Plate'. The trademarked revolutionary Power Plate assists the vacuum of the fast moving air by drawing the fastest moving air molecules through a precisely positioned hole in the plate, drastically increasing the speed of the top and bottom venturis entering the cylinder. With this modification, the result is volumetric engine efficiency through uncompromised airflow velocity. Rated as Dirt Rider's 2005 Product of the Year.


PowerNow Dyno Charts
The top chart shows "1/4 throttle" HP readings from a CRF 450 and the lower chart shows the same motorcycle with the throttle fixed at "1/2 throttle" opening.  The blue line shows the HP output of a stock motorcycle.  The red line shows the HP output of the same motorcycle with the original Power Now installed.  The purple line shows the HP output of the same motorcycle with the "new" Power Now installed.  The "new" Power Now, introduced in early 2004, features a 1/4" hole in the horizontal plate and significantly increases power output at smaller throttle openings.
