Hmmm, quick search says "35 ftlbs". :p

The UD's don't require a chip change but the blower pulley will usually tend to lean out the motor some.

ya i saw teh 35 torque, but then i also saw that no torque is required, so it was mixed answers which was why i asked again. already got the blower pulley on and am gonna get the custom chip made before underdrives so that was the answer i was looken for. :)

Well, the trick with the SC pulley is that 35ftlb is often not enough torque to press it on. So after you have it pressed down all the way, back the nut off and retorque to 35ftlbs. Of course if there is any remaining locktite on the threads your torque reading will be invalid anyway....

Now you know why there are differing opinions, but the 35ftlbs is the correct answer, others are just guesses.
