I'm running the 2.1 at 16psi on a 6 rib setup, except for the Innovators West 8 rib dampener. It requires monkeying around with the KB idler pulleys and a good, high strength tensioner to totally eliminate belt slip. I've had zero belt slip since getting these issues straightened out early on during the break-in process, and that's been about three years now.

Just for the record, Kenne Bell has ceased selling the 99-01 Cobra/03-04 Mach 1 2.1L complete kits due to Ford discontinuing manufacture of the lower intake that they used in the kit.
