I run the ovs air box and have cutler big bore dual injector throttle bodies. I run 1 set of m1000 injectors and another set for the secondarys. We run the boost-it box and it works great.. If I were to do it again I think the ovs needs a bigger bov at 12-16 lbs on a 1000 with a 76 turbo. I still have a .82 tial on there and it is pretty unbelievable how strong it is. I have a huge box of charge tube 2 1/2" and 3" tubes, sweaps, 135's, fittings and couplers and clamps. So if you need a part see if I got, cheap... twisted has a good airbox, but the 50 mm bov is in the charge tube. I like my ovs as it has a mount that keeps the throttle bodies held to the block and helps keep from tearing boots.
