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 Kit. If the belt is slipping, then you are not achieving full boost. This snub idler and pulley kit will not add power itself, but the elimination of belt slip allows full boost which is where the power increase comes from. It utilizes three 100mm Idler Pulleys, one 92mm pulley and is a simple bolt on installation. It is black anodized for long lasting good looks. Plus, the new billet idler pulley allow for reliable operation, unlike the stockers.
Bought the kit form LMR as they had the best price and it was available. Great looks and comes with all hardware to install. Had a small problem and LMR rectified it ASAP and got me what I needed. Top notch part and customer service
Just a quick note to say what great people (Eddie Davis) are at Latemodel Restoration. I ordered and bought a set of Track Pack Wheels for my 2014 Mustang GT.Their prices and service is the BEST in the MUSTANG INDUSTRY, not only the price and service but the honesty. The wheels came thru with the wrong center caps one call to Eddie Davis corrected the situation in one phone call and the next day I had the center caps (FORD RACING) the correct ones no BS, they just did the Right Thing,whereas in this Day and Age you don't here that often. LATEMODEL RESTORATION is the only place for your Mustangs parts and equipment, trust me try them and you will see what I mean!!
