An Unorthodox Racing's CNC-machined, billet aluminum underdrive pulley set was also added. This pulley set has been dyno-proven to add 6-wheel hp to the SR20. Additionally, the UD pulleys also help reduce a classic SR20 weak spot. The SR20's water pump cavitates at about 6500 rpm. This makes trackdriven SR20s prone to overheating.
