Ok thanks. Are the MAC U/D pulleys any good? I know some selling a brand new set for $100 shipped. Are those piggyback also?

Best company is Steeda, hands down.

Originally, I installed MAC 'piggyback' pulleys. The stock crank pulley is mated to the MAC aluminum crank pulley and both are installed as one piece. Big mistake. It cause a vibration in the motor between 2500-2800 rpm, which in set of the CEL with a misfire code. So, after trying for two weeks to fix it, I gave up and bought Steeda pulleys. They are steel and there is no piggyback on the crank.

I have had zero trouble with my BBK piggyback style pulleys. Every1 just complains because you cant use a Steeda timing adjuster once you put the pulleys on. But it doesnt matter, get a SCT or Diablo tune and you adjust your timing electronically through the tune instead of manually with the external timing adjuster.

One last question. As my screen name says, I am going to make my GT into a Saleen, well to an extent. I know another person selling Saleen 4.6 U/D Pulleys. I would assume they would be better than Steeda? Sorry for the questions but so far I understand that Steeda is the best, but what about these?

Steeda is the best. You cant find u/d pulleys that are better.
