[QUOTE="SRAD97750, post: 95127, member: 425"] Here is some actual information on the subject. [U]PowerNow[/U] "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." I can see how this could work to benefit smaller throttle openings, as intake diameter is less crucial under 1/2 throttle. But once you get it over 1/2 throttle, technically this "plate" would be directly in the airflow. I think this would be a detriment to an already choked-up stock intake boot when air/fuel volume is most crucial.(WFO) [U]Spark plug boosters[/U] PLASMA "The Plasma Booster sets up a capacitance/inductance feedback circuit between the spark plug and ground that will cause the spark to fire multiple times after the initial spark.
