Pulleys

When converting your M44 / M50 / M52 / M54 / S50 engine, you often reach the limits of the original belt pulley at higher speeds, which leads to a drop in performance from the alternator. A simple and effective solution is to replace the pulley with a different gear ratio. With the MRT pulley you change the transmission ratio from the original 3:1 to 2:1 and solve the problem.
