2003 Patent for Exhaust Scavenging

Gale Banks is awarded a United States Patent for his innovation in exhaust scavenging. He invented a ballistic flow device to overcome the aerodynamic problem that occurs where tubes join within a single collector: a “dead zone” that kills exact gas velocity. Banks PowerPickle fills that void and utilizes the rotational firing order to maximize exhaust extraction.

This detail, exclusive to Banks, captures exhaust-gas action and turns it into massive torque and moves the peak 800 rpm to match the shift point. Banks integrates tuned-length tubes into a design that allows rotational firing of the cylinders the exhaust, minimizing back pressure and maximizing torque.

Think of it this way: the PowerPickle makes the header’s collector into a gatling gun, directing each exhaust pulse out separately and unobstructed. This invention is particularly beneficial on V10 engines, such as those used in motorhomes, vans and trucks.
