Abstract: Formula Student Racing Competitions are held across the world organized by SAE (Society of Automotive Engineers). One such growing event is the Supra SAE India held by the Indian branch of the association. In order to restrict the power of the engine in the competition, SAE made a rule to put a 20mm air restrictor before reaching the cylinder head. In a field especially such as Mechanical Design, no model is perfect and there is always room for improvement. This has been our motto which has always been tried to be achieved. In order to overcome the effect of restrictor, it can be minimized by minimizing the pressure difference between the intake and outlet of the restrictor. In order to achieve this, we have used a convergent-divergent nozzle of 20mm diameter. Computational fluid dynamics gives an alternative method of experimenting without a prototype. Meshing plays a very important role in any numerical simulation, in order to get the accurate results, a structured mesh is created and analysed. The work in this paper is based on the car SHIV1.0 which was presented in the Supra SAE 2014-15 event. The air intake manifold which is modelled, designed and optimized is based on KTM Duke 390 engine considering its throttle body and cylinder head specifications.
