they under drive pulleys will slow down you alternator, water pump, powersteering pump and relieve some HP from the crank

the e-fans replace the belt driven fan between teh 2 mods you'll about 15-20rwhp

rear wheel horsepower. (You have flywheel horsepower, which is what most manufacturers give you. EX: 300hp 5.4 3v. Then you have RWHP, which is Actual horsepower to the ground including driveline power losses)
