Feeling like your SkyActiv powered Mazda isn\u2019t getting the \u201cshining\u201d attention it deserves? Maybe you\u2019ve already bought every CorkSport item you can, but you just want more! I can\u2019t blame you; it\u2019s a virus that all car fanatics fight.  <\/span>So here\u2019s fuel for the fire! Introducing the aluminum crank pulley<\/a> for 2.0L & 2.5L SkyActiv engines!<\/p>\n\n\n

Manufactured from high-grade 6061-T6 aluminum, this precision-machined crank pulley is sure to give you that extra level of detail you\u2019ve been searching for. <\/p>\n\n\n\n

This crank pulley isn\u2019t just for looks, folks; it\u2019s got bite, too!  With a 70% weight reduction compared to the OEM component, your engine will<\/span> rev faster due to the lower moment of inertia of the rotating mass.  <\/span>I can\u2019t guarantee your bum will feel the difference, but your 2.0L will.<\/p>\n\n\n\n

You may also wonder: \u201cThe OEM component is steel, will the aluminum be strong enough?\u201d Absolutely! The accessory belts put a very small, almost insignificant, amount of force on the pulley.  <\/span>The real concern would be the bolt that holds the pulley on, but we got that covered with our FEA testing (see below) and over a decade of use in the community and our cars.<\/p>\n\n\n\n

To be confident in our products, we conduct FEA (Finite Element Analysis) on all applicable components.  <\/span>In this case, the bolt clamping force is holding the pulley on the crank.  <\/span>The crank pulley bolt is an M16x1.5 with a torque spec of 67-80 ft-lb.  <\/span> I used 79 ft-lb, which creates a clamping force of 7557 lbf.  The maximum stress is ~12420 psi, which is f<\/span>ar below the material yield strength of ~40k psi.  <\/span>So what does this mean to you? You can (but shouldn\u2019t) torque that bolt down to ~250 ft-lb without worrying about your beautiful new pulley being structurally damaged, but you will have to worry about getting that bolt out next time; that\u2019s your problem.<\/p>\n\n\n\n
