Stage 1 Supercharger kit
Complete stage 1 supercharger kit!!
The Porsche 928 has such a cool look with great handling and performance, but lacks the HP of modern day super-cars. The stock 928s4 has 316hp, and that's pretty good, but with a quick 6+ lbs of boost, this Rotrex supercharger kit can take your engine to 450hp!! Rotrex uses the latest design in supercharger technology to produce the most compact, quiet, and dependable supercharger available today. You will not have to remove or change any major components like the crank pulley, radiator, fans, A/C or air pump. Our kit is very easy to install, and can be done in a few hours depending on your skill level and tools. Full instructions are included.
Kit includes everything needed for a quick and painless installation. Superchager, mounting bracket, belt, tensioner, matched 36lb injectors, new fully assembled high quality lightweight braided fuel line & connectors, replacement drivers side fuel rail, custom fuel and spark chips, silicon hoses & connectors, aluminium pipes, pressure release valve (bov), K&N high flow filters with enclosed recirculating cool air system, and more.
Supercharger is easily removed to switch back & forth between stock and supercharged. As you may need to pass an inspection, or want to sell the car without the supercharger. You can even drive the car with out using the supercharger while it is still in place. Yes, simply install the original alternator belt and drive. When you reach your destination, reinstall the supercharger belt, and power up!
Standard Kit includes black silicone connectors. If you want special colors like blue or red you must specify, and this may require extra time. $200 core charge is for return on your stock drivers side fuel rail. A replacement fuel rail will be included in your kit.
When your ready for even more power, a Stage 2 kit is available that utilizes all the same components in the stage 1. You just add an intercooler setup, and install a smaller supercharger drive pulley for more boost.
