Perrin light wieght pulley
I have read a lot of 2 sided posts everywhere about the pulleys. Most are old and on here around 2012/13 post. I'm just curious as of now what everyone's opinion on them and now that these cars have some miles have anyone had any problems. What exactly are people saying when they say they're acting as a damper and causing barring problems?

Holy eff this is a topic that has been, and will be beaten to death on every Subaru model. Do some research and come to your own conclusion here. Hardline benefit results? You will find almost nothing but subjective results.

Oh he will pitch on this subject!
He will also get called all sorts of things but he is right. I will let him explain the facts to you though since he is much more knowledgeable on the subject than I am. My opinion on it is save your money for something that actually makes an impact. Oh great, now I will get called names as well.

That's what I'm trying to do here is build my own opinions and conclusion. I agree they beat the snot out of this topic especially on the Wrx forums and everyone is 2 sided and that's fine. My goal here is to see how people who have ran it over the years are holding up now. Also I would really like to understand exactly what is occurring on the opposing argument that it damages the car with the whole damper bearing deal.

Yes, I know the difference. 99.9% of "dyno" results for the lightweight pullies either show minimal gains within tolerance of a dyno or they're inconclusive, or better yet done by people who want to sell their product. The biggest benefit people see from this are the "feels like it revs faster" benefit. |

I personally will never, ever, for any reason, even consider a dyno reading within 5HP one way or another as accurate when measuring mods. These places that throw a pretty graph up and say "look our xxx gives you 3 more HP" are only proving that there can be a 3HP variance in the dyno reading between pulls.
