Has anyone really noticed a difference with this? I'm curious because I am pullied and went to the track on Friday night. The temps was around 70, but it was very humid out and I noticed my Eaton was sounding tired after my second run, although my times stayed consistent. I don't know if it was the belt slipping or from the heat. So, before I spend $400 on a new intercooler, has anyone used this and actually found it worked better than the factory one?

I've already ordered a new belt and a steeda idler to wrap the belt tighter as an interim fix.
