I got a Metco 100mm dual BB idler and a 2.93 pulley laying around so my plan was to throw both on with the stock belt. The problem I'm running into is that the 100mm idler is a tight fit with the 3.1 and it's pissing me off. I want to try it with the 3.1 first to see if my MAF, pumps and injectors can handle it.
I googled the site and checked out CobraBob's page and the general consensus is that you don't need the idler with a 3" or larger pulley.
Does the 2.93 fit that criteria? It's close enough to 3" but I wanted to make sure. Maybe I don't need the idler and can run it without? Also, would the 90mm pulley be a better fit? instead of the 100mm on the aux idler? Maybe I could swap one of my engine idlers for the 100mm auxiliary idler.
