APR 3.0 TFSI supercharger drive and crank pulley upgrade kits have been designed to dramatically increase the rotational speed of the factory supercharger. When combined with APR's Ultra-Charger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance! The supercharger drive pulley decreases the diameter of the factory pulley from 63.25mm to 57.75mm, which in turn spins the supercharger 9.5 percent faster. This results in a healthy bump in horsepower and torque across the entire rpm range with the supercharger operating at a higher rate of speed. The pulley is CNC-machined from billet stainless steel, E-coated factory black for an OEM appearance and is press fitted to the factory supercharger unit. The supercharger crank pulley increases the diameter of the factory pulley from 162mm to 187mm, which in turn spins the supercharger 15.4 percent faster. This results in a larger bump in horsepower and torque across the entire rpm range, as the supercharger is spinning at an even higher rate of speed. The pulley is CNC-machined from light weight billet aluminum with weight saving pockets throughout and has an anodized black finish and includes new crank pulley bolts. It retains the factory harmonically balanced crank pulley and bolts on top of the existing unit. Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning faster than stock, which results in an even higher horsepower and torque gain across the entire rpm range. However, at the airflow levels achieved with a dual pulley setup, maximum power is severely restricted by the factory throttle body unit. APR's Ultra-Charger Throttle Body Upgrade is necessary to take full advantage of the dual pulley configuration and is available in platform specific variations for the B8/B8.5 A4/A4/S4/S5, Q5/SQ5 and C7 A6/A7.

March Performance Ultra Series Chevy Small Block serpentine systems bolt to the front of 1969 or later small block Chevy heads. Precision CNC-machined from solid billet 6061-T6 aluminum to fit perfectly and handle high torque and vibration, these bracket kits come complete with stainless steel tensioning rods and chrome moly rod ends for high performance operation. All necessary hardware included. Powdercoated to eliminate polishing in those hard to reach places. Matching serpentine pulleys are precision CNC-machined from 6061-T6 aluminum. This is the same material March uses for NASCAR pulleys! These pulleys will not fracture like common cast pulleys. High tensile strength means much longer wear. March hard coats the high-wear areas on the high-water flow ratio pulleys! The street rod ratio increase water flow and fan speed. This helps at critical low speed driving.

March Performance Chevy small block serpentine drive kits simply mount onto the front of your water pump and manifold. These pulley kits are for people with single-carbureted engines, who want to high-mount the A/C and alternator. The pulleys are precision CNC-machined from solid billet 6061 T-6 aluminum and have a maintenance-free, clear powdercoated finish. These high tensile strength pulleys will not fracture like common cast pulleys, since they were made for much longer wear. Their street rod ratio increases water flow and fan speed, which will help during critical low-speed driving.
