Most Sprint Car motors use a gear drive timing setup, but Anderson says their tests have proven that gear drives can transmit power-robbing harmonics. Anderson uses a timing chain setup for the Fords using Roush's Hy-Vo timing chain. It is hard to see here, but it is much heavier duty than the standard double roller timing sets most of us are used to. It needs to be because it not only spins the camshaft, but also the five-stage oil pump, the power steering pump, and the fuel pump.
