So i was reading the new Evo brochure, and it says they have hollow cams causing them to be 2lbs lighter. Does anyone know what kind of material the the z31 cams are made of?
I wanna try getting them on a lathe and drilling them out at least as big as the bolt holes. If i can lose 4 more pounds on the rotating assembly that would be great. For every pound lost off the rotating crank assembly is an average of 2.38hp. Since the cams are spinning half as fast, you would gain 1.19hp per pound lost. Remember every pound counts.
