Convert To A 8 Rib Belt System For High Blower Speed/Big Blower Applications
The 2005-2010 Mustang GT 4.6L 3v comes standard with a 6 rib belt system. You can convert to a 8 rib belt system to deal with high blower speeds and/or large blowers.
We suggest doing this when you get to the 575-600rwhp range.
Converting to a 8 rib system get’s you 33% more belt contact. It doesn’t seem like 2 additional ribs will do much, but they do. A 33% increase in anything performance related is a very large increase!
This kit comes with extra/different size idler pulleys so you can dial your tensioner preload in perfectly without having to take a lot of trips to the store.
