Just as I promised, here is the data on the Bullitt vs stock GT pulley issue. I also included a comparison of my car's dyno results with 1999 and 2001 Cobras and 1999-2001 GT's. I'm not boasting I just want to hopefully reveal why a Bullitt is more than just a great looking and handling car but a performer as well and thus worth every penny.
(This will be a two parter because my server is being very weird)
As for the question of the pulley size difference; here is what I discovered.
Bullitt water pulley 5.5 GT 5.0
Bullitt alternator pulley 2.50 GT 2.25
Bullitt crank pulley 6.75 GT 6.75
The pulleys were in fact optimized for performance by Ford at the factory as promised. I gained a few more HP and TQ because the BBK kit comes with a crank pulley which uses the stock as a harmonic balancer. It is therefore by default smaller than stock.
