A company used to make a cog setup for the 03 cobra. I dont think its being made anymore and ithink ppl broke stuff when the used them but i could be wrong.
Cog drives are not ideal for street applications or cars with manual transmissions. They are really hard on parts, especially when there are sudden RPM changes. If you are looking for more belt grip, look into larger serpentine set-ups. Unfortunately, to my knowledge, no one has a 10-12rib serpentine set-up available for the Cobra's with any of the eatons, TVS, Whipples or KB's... Not mass produced anyways.
