This package includes a pair of 10 rib pulleys for the supercharger and the jackshaft that give a total of 15% overdrive for the supercharger. A premium quality 10 rib SC belt is included as well as a pair of the stiffer tensioner springs.
This billet aluminum crank pulley is significantly lighter than the stock steel crank pulley and best of all...it allows for another 10% of overdrive on the supercharger without worrying about belt slippage. Typically adds 3 to 4 psi of boost.
These steel replacement tensioner/idler pulleys will substitute for the original plastic ones that are likely worn out on your 3.8L SC motor if it has more than 100K miles. The original bearings can seize at any time leaving you stranded. They are also much quieter as they do not develop bumps on the outside diameter as the stock plastic pulleys do.
One of the best bang-for-the buck items for the SC engine. Lo-Profile and High Flow! Add 10-15 HP by improving the efficiency of your stock intercooler.
An exact replacement motor for the stock radiator fan on the '89 to '93 3.8L SC engines.
1.73:1 ratio, race quality extruded aluminum pedestal style rocker set. Comes complete with allen head fasteners. These are almost too good looking to cover up with your valve covers.
The SCP Fuel Pressure Gage Kit allows you to accurately monitor your fuel pressure. This valuable information allows you to monitor and diagnose fuel pump and regulator problems, as well as to test for leaking injector nozzles and regulator diaphrams. It is also great to have pressure readings when dyno tuning a car.
The stock regulators are nonadjustable so this item can be a terrific tuning tool and a highly recommended upgrade when you are changing your fuel pump or upgrading injectors.
A complete kit with high quality Walbro pump, vehicle specific sock filter/screen, gasket, and misc. hardware....a direct fit!
