PRODUCT DESCRIPTION
Underdrive pulley systems increase engine horsepower by reducing the amount of power required to drive external engine accessories. For example, the alternator, power steering, water pump and air compressor rob horsepower from the engine. By replacing factory-sized crank and accessory drive pulleys with a resized pulley, the accessories are slowed, resulting in more horsepower available to the drive wheels. Typically, a set of Auto Specialties street pulleys will increase horsepower by 12-15, and increase mileage by 2 to 3 MPG. All pulleys are manufactured from Billet Steel or Aluminum, exceeding factory quality.
Due to the difference in diameter from the stock Mustang pullies, the alternator and charging system may need to be upgraded if you have a large stereo system
That's funny, I was just thinking about how I want to get rid of mine last night.Under-drive pulleys. Biggest waste of money invented for Fox cars.
12 to 15 "claimed" fly-wheel HP with a 22% under-drive. Already, I call BS. In the real world, it's more like 6-8 fly-wheel HP.
Next, let's assume that our alternator needs upgrade because our 22% under-drive doesn't spin our 80 amp alternator fast enough to get even half of that rating at idle or because our headlights are dimming at night. Now we need a 3G alternator upgrade and it still might not be spun fast enough at idle to make a difference. Damn... ditch the alternator pulley. Now we have a 14.67% under-drive less if we opted for the alternator over-drive pulley to fix the charging problem). Our 8 HP just dropped to 3 HP.
But wait.... all that HP we added (by means of other mods, perhaps even a blower) and now the cooling system is beginning to show signs of struggle....
Need I go on?
Totally forgot about the first and last one, but that's a whole new threadMy least favorite mod is probably madmike lol. Jk. Tinted windows,headlight covers,uglyass euro tailights,no tailpipes(especially on an LX),too big of a cam-causing lack of performance and drivability,and then madmike
I agree with this as I have delete the AC and the rear seat just to have to go back and rebuy those parts. The big issue is that you are buying them typically at 3-5x more then what you sold them for.AC, power steering and rear seat delete.
All stupid, all things I've done.
Let's see, you lose value, you sweat your ass off and your car is hard to drive in parking lots.
Great plan...
Edit: Forgot to mention, when you come to your senses you have to buy parts to put them back together, making them even worse.

Back on topic, 87-93 noses on 4-eye cars, especially when done to a Capri... Gives me the urge to find an 87-93 car and stick the 85-86 nose on it (my favorite fox look).
I know, right? Cats and dogs sleeping together.......Wait... Mike's not a mod anymore, and Karthief is? Where the hell have I been?
