Most of the 13 gt500 guys are ditching their stock TVS units for VMP's, etc. Could you mate a 13' tvs onto a 5.0 with the right manifold? Considering their a hell of alot cheaper and almost as reliable?
The 13-14 TVS superchargers will bolt right onto the Roush manifold. They have a 10 rib pulley drive where as the typical Roush Coyote spec pulleys have a 6 rib drive. Other than that the blowers are almost identical. It is just not worth doing unless someone offers a kit to accomplish this without using Roush parts such as the DOB kits for the 3V cars. I am sure he is working on a Coyote version. http://www.departmentofboost.com/
Department of Boost is developing a manifold for the 5.0 guys to accept a GT500 Eaton M122 or TVS. They made one for the 4.6 3V guys and are in the works for making one for the 5.0 but won't be till late Fall they said. I was curious if you could bolt a Eaton M122 onto a TVS/Roush manifold.
