Today, I am going to try to eliminate a failure point on the Mini: the crank pulley. To give the car a more refined experience, BMW added a two piece crank pulley to the Tritec when they adapted it to the Mini; the rubber holding the two pieces together eventually fails making the car undriveable until replaced. To prevent this, I am going to install a one piece aluminum crank pulley from Alta; this pulley is much lighter and slightly larger in diameter to spin the supercharger faster (it won't make a huge difference). Most people are concerned because they think the crank pulley is an engine damper; while it will help with some secondary harmonics, the two piece flywheel will accomplish the same function. Plus, the Tritec is used in other cars with a single piece crank pulley without issue. You could run a fluid damper, but for my purposes, the extra investment isn't worth it.
