I'm looking to go twin screw soon just putting out a feeler to see if can do it now before I put the car up for the winter. I have a stage 4 Steggy painted black with Stock port matched Plenum and TB also painted black. Comes with hub and 2 pullies 2.76 (Red) and 2.9 (Silver) and matching belts for the fit. I'll post up pics when I get home looking to get $850 shipped
