    In the automotive industry, enhancing and improving the engine performance is one of the major work for improving the overall performance of the engine and vehicle. Every iteration of the engine, will overcome the issues raised in the previous batch of the engine as well as improve the brake power and brake torque of the engine. There are a lot of aspects need to be considered in achieving this objective such as intake part, exhaust part, camshaft and cam profiles. Thus, this research is proposed to enhance overall engine performance by improving current cam profiles for MODENAS CT115S model. The current performance for MODENAS CT115S below than other competitors. By using geometrical analysis, five new designs were proposed with different cam parameters including circle base radius and cam profile. By the aid of AVL Advance Simulation Technology software, the benchmarking of real and baseline data were conducted in order to verify 1-D simulation planning for the simulation purposes. Once the result of the simulation was in the acceptable range, the new designs can be investigated to find the valve lift and cam characteristics. From the valve lift curve, new cam designs were undergoing simulation to determine the engine performance curve. Among all new cam designs, cam design D, with 14.5 mm plotted the second highest maximum valve lift but generated the highest brake power and brake torque curve. Therefore, this cam design was the optimum design among all five designs with the best performance curve, with 8.89 N-m at 7000 RPM of brake torque and produced 7.25 kW of brake power at 9000 RPM.
