I have the three UR pulleys on my z and at the end of the month I am getting the PE TT kit put on. My question is, will I have to worry about the UR pulleys underdriving the water pump to the point that the cooling system is not cooling the motor enough with the TT kit on?

 

Getting the Vortech installed as we speak and was told I had to lose my UR Pulley kit. Really liked them too. Not sure if you lose them with TT.

 

Had to lose them because the Vortech adds another pulley to the car's motor.

A TT won't do that. In my mind, you will overwhelm the radiator and the rest of the cooling system as well as the water pump if you're going hard. The Z doesn't really have that much space under the hood and it gets hot. Realistically, you can always just take the pulleys off at a later date if it becomes a problem.

 

Heh, I received a SES light (Random Misfire) and knowing what I know about pulleys during my eclipse days, I replaced them with the stock pulley. No SES lights, smoother idle (real glad about that one), and a stronger alternator for my custom audio
