Thumbs up Steeda Underdrive Pulleys

Please let me know if I can help you with that.

http://www.steeda.com/store/steeda-u...ustang-gt.html

Get back the horsepower and torque your belt driven accessories steal and start enjoying better performance and gas mileage today!

Steeda's underdrive pulleys slow down accessory speed by about 25% reducing parasitic acccessory drag on the engine. This drag reduction results in an increase of up to 10 horsepower and increased gas mileage!

Steeda underdrive pulleys are the only pulleys engineered through our unique partnership in Ford's technology transfer program to have the proper torsional vibration dampening characteristics for your 4.6L engine. No other manufacturer can make this claim.

The real effect of UDPs on your AC is that it will take longer to cool down the interior--at least that's my experience for the last three summers. I live in Southern California, and it gets hot during the summer.

I think the biggest difference is at idle or stopped at a light any other time I couldn't tell a difference with the ac

headlights also are a little dimmer at the stop lights and you can see them get brighter when you give it a little gas.

I have a 2001 GT. What length of belt would I need to get after installing Steeda pulleys?
