Aluminium or Steel Pulley
Posted: Mon Feb 05, 2018 2:45 am
I hear stories about aluminium pulleys that make me think I should be going steel billet for my project and I already have a 3.5lb EMPI item.
The car will be a mild tune 1904 mostly street, but not daily driver, and occasional strip. It has a DPR crank and lightened flywheel and will be balanced end to end when we sort out a pulley. If we used aluminium and it did wear excessively then we would need to replace it and that might affect the balance worse still would be it running off centre or even breaking up. Breaking up might cause other problems to the crank trigger.
However I am having a major problem sorting the crank trigger as most all are designed with aluminium pulleys in mind.
