Swapping out to a smaller supercharger pulley is the easiest way to add power to your 2003-2004 Cobra short of a tune. However, the smaller you go, the less contact area the belt has on the pulley. This leads to the belt slipping.
Luckily BilletFlow devised the solution by way of this Snub Idler Pulley & Bracket. If the belt is slipping, then you are not achieving full boost. This snub idler will not add power itself, but the elimination of belt slip allows full boost which is where the power increase comes from. It utilizes a 100mm Idler Pulley & is a simple bolt on installation. It is black anodized for long lasting good looks.
This is by far the best experience I have ever had buying parts for my mustang. There is no other place for me, then LatemodelResto. I have bought multiple parts over multiple orders and have had nothing but a smile from ear to ear. Aaron Westerman was my contact person from LatemodelResto. I could not ask for a better customer service representative than him! He went above and beyond multiple times for me and made my experience with Latemodel the reason I keep coming back. LatemodelResto will continue being my #1 stop for my Mustang parts.
