look guys I going to purchase an underpulley set from TP it is 2 pulley set just wanted to see if any of you have any experience with this kit you could pass on its water pump pull and crank will not effect the charging system thanks

 

i wouldnt use em not its worth the 3 hp you get. i had them on my 4.6 mustang and performance wise i couldnt tell the difference.your lights will dim when you hit the brakes at idle. my power steering pump would start to moan when you crank the wheel while stopped. super easy to install though

 

Put the money towards some e-fans. You'll gain more power there!!
