Most "spun" bearings are rod bearings. Keep in mind inline 6 motors have more issues due to the longer crank. Our crank is much shorter and can handle stock or slightly higher than stock redline with no issue. Do not confuse the issue. Stick a a ati dampner and i can spin the rod bearing on it too. The main are where the ati should help and in reality te vg does not need much help in that area.
