Abstract: A device 10 and method for maximizing internal combustion engine horsepower for a preselected RPM range includes a plurality of velocity stacks 12 removably inserted via grommets 16 into apertures 17 in an air box portion 14 of the internal combustion engine while the air box portion 14 is secured to a throttle body portion of the internal combustion engine, and measuring power generated by the engine for the preselected RPM range with a selected velocity stack 12 removably secured to the air box portion 14 whereby a velocity stack 12 is ultimately selected that promotes maximum internal combustion engine horsepower for the preselected RPM range.

Abstract: A system 10 and method for maximizing power output from an internal combustion engine includes a control module 12, a motor power output measuring member 14, a microprocessor based digital computer 16, connections 18 between a control module input 13 and the computer 16, and connections 20 between a control module output 15 and one or more existing motor power variable control members 22 including, but not limited to, fuel injectors, ignition timing components and air flow control components.

Abstract: An improved roller 12 for a dynamometer 10 includes a plurality of equally spaced, congruent recesses 16 parallel to the longitudinal axis of the roller 12 and circumferentially positioned around the perimeter of the roller 12. The recesses 16 form a plurality of equally spaced, substantially planar, congruent surfaces 18 parallel to the longitudinal axis of the roller 12 and circumferentially positioned around the perimeter of the roller 12. The surfaces 18 engage the drive wheel of a vehicle and limit slippage and/or creepage between the drive wheel and the roller resulting in increased power transfer between the drive wheel and roller and increased dynamometer accuracy and repeatability.

Abstract: A carburetor device (10) having a plurality of apertures (12) circumferentially positioned and equally spaced around an orifice (14) portion of the carburetor device (10). The apertures (12) have a cross sectional area dimensioned to allow an air-fuel mixture to flow therethrough when a throttle member requires maximum power and corresponding air-fuel flow rates. The apertures (12) direct the air-fuel flow (30) through a “puddle” (27) of fuel that has accumulated in the bottom portion (28) of an outer well (18) of the carburetor (10) during the normal operation of an internal combustion engine. When maximum power is required from the engine, the increased air-fuel flow through the apertures (12) causes the fuel puddle (27) to vaporize or “mist”, allowing the fuel to become a part of the air-fuel flow stream supplying the engine's cylinders (25) thereby increasing the engine's power and response while decreasing the engine's hydrocarbon emissions.

Abstract: An adjustable interlocking ignition rotor device 10 includes a first member 12 having a plurality of orifices 34 radially positioned around the axis of the first member 12, a second member 14 having a plurality of orifices 56 radially positioned around the axis of the second member 14, and an index screw 16 to secure the first member 12 to the second member 14. The first and second members 12 and 14 are secured to a base portion of a distributor assembly or one end of a crankshaft to adjust the timing of an internal combustion engine. The engine timing is easily adjusted to an advanced or retarded position in relation to a zero degree setting by counting from a zero degree orifice 78 and 80 in both the first and second members 12 and 14 in a corresponding advanced or retarded direction, a quantity of orifices corresponding in number to a predetermined degree of engine timing.
