billet crank

this is the billet crank, brought from racetorations.made from EN40B, nitrided,able to rev to 8000 rpm.the engineering process is the same as formula one. dummy mains allow for less counterweights, and webs.the crank uses the same stroke as standard,95mm.however it is not cross drilled,which is something i wish to incorporate into its design. it also features eight fixings for flywheel attachment.
