E85 Build Not Making Boost

[Mopar16]

Hello everyone i wanted to get everybody’s initial reaction as to what this could be? I took my car to the track and noticed the car was slow. I thought it might’ve been bad E85 but then I noticed it wasn’t making boost. Checked belt to see if it was slipping and then I noticed this. No check engine lights.

Anybody have any idea what could be the cause and what this is? Feels like oil but I’m not sure.

Pop the blower belt and check it out.

There have been some litens failures lately I believe.

Looks to be a pulley issue, in the pic it almost looks like theres belt fibers in that oily substance.

Looks like a failed decoupler in the pulley.

Looks like a Litens pulley, right? I don't know what they look like when they fail, but what you have there is some weird goop.

Yes that is correct. And yeah it looks and feel like some kind of lubricant. It definitely looks liked a failed pulley and the performance shop seems to agree but still gonna take the car back to them just to be on the safe side.
