okay! so my question is will a STOCK size alumiumn pulley be bad????? I know unorthdox makes one, but woudl it be bad or good to use it?? any help would be nice thanks guys

PS yes it is a lightened pully but its the same size

 

i know that my experience with an aluminum pulleys was frustrating between managing the belt slip. Not sure if the aluminum is going to grip sufficiently with the added strain of a blower

 

I put one on a couple years ago . i had it pulled off 6 months later because of bad results others had had . Sure enough , mine had started to wear and grooves were visable when removed .

If anything get a ATI fluid damper or simular

 

I would just leave the stock one on, too much work and risk for problems for a very small gain.

 

okay thanks guys
