Abstract: A system and methods for a turbo-boost control system are disclosed for providing a driver of a vehicle with greater control over vehicle performance. The turbo-boost control system instructs an electronic control unit of the vehicle to increase the manifold pressure to a higher level before releasing the pressure through a waste gate so as to provide a greater power output of the engine. The turbo-boost control system includes a control module, a wiring harness, and a signal adjuster. The wiring harness couples the control module with a turbo inlet pressure sensor, a manifold absolute pressure sensor, and an electronic control unit of the vehicle. The control module sends signals to the electronic control unit based on input readings from the turbo inlet pressure sensor and the manifold absolute pressure sensor. The signal adjuster includes a rheostat that enables manual adjustment of the power output of the engine.

Abstract: A combined mass airflow sensor and hydrocarbon trap is provided for absorbing evaporative hydrocarbon emissions from an air intake duct of an internal combustion engine. The combined mass airflow sensor and hydrocarbon trap comprises a duct that supports a hydrocarbon absorbing sheet in an unfolded configuration within a housing. The duct communicates an airstream from an air filter to the air intake duct during operation of the internal combustion engine. An opening in the housing receives a mass airflow sensor into the duct, such that the mass airflow sensor is disposed within the airstream. Guide vanes extending across the duct reduce air turbulence within the airstream passing by the mass airflow sensor. Ports disposed along the duct allow the evaporative hydrocarbon emissions to be drawn into the interior and arrested by the hydrocarbon absorbing sheet when the internal combustion engine is not operating.

Abstract: An apparatus and method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.

Abstract: An apparatus and a method are provided for a crankcase breather vent assembly to direct blow-by gases out of an engine crankcase. A vent base comprising a generally cylindrical vessel communicates received blow-by gases into an interior cavity of a breather vent that comprises a filter medium. Baffles disposed within an interior cavity of the vent base capture oil carried along with the blow-by gases. The captured oil is directed to an oil sump of the engine by way of a suitable hose. A bonnet fastenably receives the breather vent and is configured to reduce a buildup of oil residue on nearby engine components. An outer profile of the breather vent is tapered along a longitudinal dimension of the filter medium to facilitate unrestricted air flow through the filter medium when the bonnet is installed onto the breather vent.

Abstract: An apparatus and method are provided for a cone air filter for a closed intake system of an internal combustion engine. The cone air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base is comprised of a flange that couples with an air intake duct of the internal combustion engine. A shell receiver is incorporated into the base and receives a rigid exterior shell, such that the exterior shell surrounds the cone air filter and directs the intake airstream therein. A cap is disposed on an apex portion of the cone air filter and is configured to direct the intake airstream around the apex portion and into the cone-shaped filter medium.

Abstract: An apparatus and a method are provided for an air filter configured to be mounted onto air inlets of turbochargers and superchargers. The air filter comprises a proximal base including an inlet receiver configured to receive an air inlet, a clamp to secure the air inlet within the inlet receiver, and a first opening aligned with a screw mechanism of the clamp. A filter medium fastened to the proximal base is configured to remove particulate matter and other contaminates from an incoming air stream. A distal end cap fastened to the filter medium comprises a second opening aligned with the first opening. A conduit within an interior cavity of the air filter is disposed between the first opening and the second opening, facilitating tightening and loosening the clamp by extending an appropriate tool through the interior cavity so as to engage the screw mechanism of the clamp.

Abstract: A throttle-controlled intake system is disclosed that provides a driver of a vehicle with greater control over engine functions and vehicle performance. The throttle-controlled intake system includes a control module that is coupled with an aircharger air intake. The control module processes input signals from a throttle pedal of the vehicle and sends modified throttle position signals to a throttle body of the vehicle so as to increase throttle responsiveness of the vehicle. The throttle-controlled intake system further includes a wiring harness and a signal adjuster. The wiring harness electrically couples the control module with the throttle pedal and the throttle body. The control module sends signals directly to the throttle body of the engine, bypassing an electronic control unit of the vehicle. The signal adjuster includes a rheostat that enables manual adjustment of the throttle responsiveness of the vehicle.

Abstract: An apparatus and a method are provided for an oil filter-leak pressure-test station. The oil filter-leak pressure-test station comprises an air pump, a pressure gauge, a vent valve, an overflow reservoir, and a manifold configured to receive an oil filter. The oil filter-leak pressure-test station is configured to apply a desired internal air pressure to an oil filter for observing the oil filter assembly for any potential leaks, such as along a seal ring, rolled seam or a nut-end. The oil filter-leak pressure-test station is also configured to be mounted in a vise or similar mechanical attachment for observation to determine the extent or existence of any leak in the oil filter. The oil filter-leak pressure-test station may also be submerged in water using a submersion reservoir, so as to determine the existence and location of any leaks.
