The Oval Trumpet Airbox is a complete kit for engine air aspiration and filtration.
This device is mainly composed of an oval shaped air box in carbon fibre containing a cylindrical air filter with dynamic inlet.
Ota kit totally replaces the original car filtration box (stock air-box). Usually the original car air boxes work in such a condition as the air is recalled by the engine in a "depression" regime", thorugh reduced section tubes, thus resulting in high load drop along the aspiration line.
The OTA device, with its dynamic inlet, works in a "pressure regime", therefore it provides a constant and high rated quantity of air to the engine taking advantage of the dynamic effect of the air pressure.
In addition to its oval shape, offering high installation versatility, OTA system introduces in its inner part technical solutions which optimize the fluid dynamic of the air to the engine. In particular, the innovative element called "trumpet", which is situated inside the air box in the area close to the air outlet, thanks to its shape favours and optimizes the convey of the air flow to the engine, resulting in the diminishing of turbulences. This solution reduces the pressure drop along the engine aspiration line and, at the same time, takes advantage of the potentiality of the dynamic pressure of the air caused by the speedof the moving car.
The air filter inside the box is made of a multi layered pre-oiled filtering material which grants an high filtration efficiency against limited pressure drop in the air. The air filter has the function of protecting the engine from all the elements (debris, sand, dust) in the air flow during the aspiration phase. BMC air filter has a very low drop (i.e. the pressure difference between the air flow at the engine side and the one at the air entrance side) in order to enable the maximum air flow.
BMC air filter can be regenerated and re-used. Once the saturation level has been reached, it is possible to regenerate the filter by washing and re-oil operation performed by means of the relevant regeneration kit.
OTA kit is a universal product which can be installed in different car models.
OTA kit range is featured by different air box dimensions and by the dimension of the connection parts of the car. The choice of the proper OTA model should be carried out on the base of the features of the engine to which the device will be applied and of the features and dimensions of the elements to which the device should be connected.
Moreover, the kit includes the necessary accessories to its installation. Besides the ones already included in the kit, BMC has available in its catalogue a large range of accessories for the installation.
Its main technical features are:
- Oval shape of the air box, designed to enable high versatility for the installation of the device.
- High thermal insulation from heat sources by means of an air box in true carbon fibre at 5 layers.
- Air filter with regenerable material which warrants an high filtration efficiency with reduced drops.
- Oval Trumpet: sophisticated and designed inner system for the channeling, conveyance and increase of the air flow by introducing an innovative system/air conveyor named Trumpet.
The Trumpet, placed inside the OTA device on the air outlet side, enables to additionally increase the quantity of air to the engine by taking advantage from the dynamic conveyance given by its peculiar shape.
- Air box with sealing system enabling to guarantee the best sealing among the components, such providing the best pressure tight of the device at any Rpm.
