Pulley question

[TRD1]

I just bought a 2.93 upper pulley. What else do I need as far as idlers and all. Should I buy from Leathal? I have a handheld CAI and catback. I plan on buying a Whipple eventually but I need more from my car in the mean time. So I figure Ill do a pulley. I have a tuner with a dyno. Any help would be great.:beer:

Billetflow idlers, tensioner, and a different belt should be about all you need. I ran your same set up for a while and was happy with it. And I vote yes on Lethal. I bought most of my products from them and will do so when I get another Mustang. Do you have any mass air or fuel upgrades at the moment? You can look on Cobra Bob's site for the right belt size assuming the stock one won't work...I don't remember what size I was using.

2.93" pulley with an aux. pulley you'll need a 74.5" belt....

I`d get all the idlers,make sure you get the hard coated ones,BF or Metco from Lethal.
