Hey guys, ive seen alot of people offer light weight crank pulleys, isnt this something i dont want to do to the car unless im tracking it since i would need the harmonic balancer? or are they two serpate parts? cause i figure that when im doing the SC pulley i should do the crank pulley if it will keep my mini reliable

 

 

If you're going to replace the crank pulley replace it with an ATI SuperDamper http://www.atiracing.com/products/da...ts/dammini.htm

 

Personally I agree with v10. Get either the ATI or the PRW pulley. I did the PRW because of the price difference and all the other maintenance I had to pay for at the same time. After reading a few threads on the issue, I decided that the damped pulley was the way to go despite the weight. Mine Mini is a daily driver, not a track car, so I wanted a reliable pulley that was less likely to cause problems down the road.

 

i figured you would want to keep a damping pulley, mine is also the daily driver and i dont need to have problems down the road

 

I had an ati I bought from wmw installed at greasys a few months ago...
Car DOES seem to idle a tad smoother than the OEM.....bet the prw liquid damper would do the same if $$ is tight....
Yes....the damper IS part of the pulley....if you look at the OEM style pulley...there is an inner metal part, and then a thick layer of rubber (much thinner on a non s), than the outer metal part that the pulley rides on....thus there is s rubber doughnut to absorb what an engineer calls harmonic frequency's....the replacements us different designs to accomplish the same thing.
Wmw has posted in the past that when he takes motors apart, it is obvious from the wear, if a non dampered pulley was on the car....so for longterm reliability, a dampened pulley, IMO, is the way to go.

 

sounds good, does the ATi and prw havea weight savings over the stock? cause i wont replace if i dont have to

 

Slight weight savings....think about a pound or so...nothing huge....
If you can take a prybar and wiggle the pulley from side to side...then the rubber is starting to fail...yanked mine off early to prevent getting stuck when it did go....
It looks OK...bet I could even sell my used , good looking junk pulley to somebody online for $50....lol...might be good for 5-10k miles....but I am too honest!!
