15PSI should be a 15% pulley unless you have a boost leak or inefficient blower.

 

It should be stamped on the pulley. you may have to pull the right wheel off to get a good look at the pulley.

 

thank you.... i had a feeling that it might be...



dont really want to start pulling tha car apart if its running fine.. Tried eyeballing it but cant see a thing.

 

If you have a dental(Angled) mirror you can use that and a flashlight to reach down and look at the pulley face as well.

 

What about measuring the two pulleys, and see if the one is different by 15%?

Or isn't it that simple?

 

You measurement would give you the size outside edge to outside edge...this is not where the belt rides...also in trying to determine which pulley you have with a measurement...a 15% a 16% or a 17%, the diff is tiny..1% of the diameter..few folks can measure that well...
