Broke the car. Took it out on a back road to see if I could top it out. As soon as I hit 120mph heard something come off the car. Drove it back to base(about 1 mile) and everything seemed good until I had to turn. Steering wheel was kind of jerking. Got parked looked all around outside of car, nothing missing. Popped hood, nothing missing there, but noticed power steering pump pulley wasn't straight. The power steering pump had been leaking so though maybe the bearing went out at the high RPMs. Grabbed the pulley to see if I could wiggle it and the whole power steering pump moved. The bolts that hold it down and keep tension on belt were loose. Too dark to really see what's going on even with flashlight. What could have caused that, or fallen off the car to make that happen? Never really paid much attention to that are since it's tucked on the backside by firewall.
