The O.T.A. device – Oval Trumpet Air box – is the new high performance BMC aspiration and filtration kit; it has been fully designed and manufactured by BMC race division, the department which is constantly developing new air filters and filtration systems for racing: Formula 1 / Moto GP / WSBK / WTCC / DTM / Fia.GT / Le Mans 24 hours. The top know-how gained in over 10 years of work in the racing field is at the base of the new OTA device which will amaze you with impressive results and an undoubted increase of engine performance.
What is O.T.A.?
It 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”, through 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 speed of the moving car.
The air filter inside the air box is made of a multi layer 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, etc…) in the air flow to the engine 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.
The main technical features are the following:
1) Oval shape of the air box designed to enable high versatility for the installation of the device.
2) High thermal insulation from heat sources by means of an air box in “true” carbon fibre at 5 layers.
3) Air filter with re-generable material which warrants an high filtration efficiency with reduced drops.
4) Oval Trumpet: sophisticated and designed inner system for the channelling, 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.
5) 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.
Advantages and benefits
The joint working of all the OTA components above mentioned make OTA a device which is suitable to supply fresh and pressurized air to the engine: this brings to better combustion and performance, consequently improving the torque values (NM) and the maximum power (HP) along the whole engine rpm. In addition, OTA kit provides a sport sound.
OTA device, due to its technical and design features and to the use of racing materials can be positioned at the top both of BMC air filters catalogue and of the worldwide range of sport filtration system for road and race cars.
