Description
This for the machining ONLY of the water pump manifold core for our ’15+ C7 supercharger kits. The factory water pump manifold needs to be machined on the idler bosses by -.500″ and bottom tapped to M10 x 1.50. We supply you with a new core when the kit is bought new so this is ONLY for those who bought a used kit and whish to send in their manifold core in for machining without the $200 core charge of a new manifold core.
