Just had a couple of questions. I have a 2003 5sp P5. The car is still stock but I;d like to do a few things to it. I live in TX and it gets real hot during the summer (and spring and fall). Will an underdrive pulley decrease A/C and water pump efficiency. Also, does anyone know what the HP gain is on an AEM short ram? Thanx(flame2)
