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.
A larger MAF Housing is an awesome intake power upgrade for virtually any engine. These American made housings provide proper calibration with a range of fuel injector sizes through the use of interchangeable sampling tubes within the body of the housing.
Everyone should have one of these steel grommets/clips on your Throttle Body. These can save your transmission from burning up if the rubber grommet fails and the TV cable pops loose. If this happens your AOD transmission can become toast in a matter of minutes.
Replace those wimpy fluid filled mounts for better performance and substantially improved durability. Simply the finest mounts available for your car and ours don't raise the center of gravity of your engine. No perceptible increase in vibration or we will give your money back!
The belt tensioner that serves the main accessory belt on the 3.8L supercharged motors is prone to cracking where the tensioner springs are attached on the body. These are located next to the cars alternator. This item will fit all years...'89-95
