You gotta be pulley'in my leg!

OK - someone needs to stop with all the group buys - just too tempting!  Ended up getting a new developmental 84mm pulley that fits on the supercharger, instead of the usual crank pulley that spins everything faster/harder on the engine.  About 28.5% of the rotational weight has been taken off the pulley which means less wear & tear on the engine and components.

Here's the new (left) vs old (right) design - note the thickness (weight) on the OEM design


What's nice about this design is that it is less weight and offers faster spooling of the S/C instead of the stock pulley - it's been developed to meet OEM quality and has a slip-resistant coating on the ribs.  Here it is, fresh out of the UPS box.  Just waiting to add 1.5-2PSI of boost :)


It looks to be a stellar part and much cheaper than the crank pulleys which (IMHO) tend to be more trouble than what they're worth on a daily driver.  I hope to get this installed soon :-)
