Most guys that have bought these, have sold 'em. Our cars are electrical as hell and potential idle charge-rate problems have occured with underdrive pulleys. The other thing to note is that alot of us have overdrive waterpump pulleys to help keep water circulating thru the heads... They don't make these w/o a purpose.

Jimn8or is right! I had an undredrive crank pulley and I took it off, reinstalled the stock one because the alternator wasn't turning fast enough to send a good voltage supply to the fuel pump, and also, I added a hot wire kit. One other problem this creates, is that I have a front mount intercooler and the engine must get all the cooling the water pump can give, and slowing down these two accessories can give you more problems that help you...
