I met the designer of the Sprintex Supercharger at last year's SEMA show. He'd originally designed this supercharger for a 3.8 or smaller engine. He was at least over 70 years old and had told me he'd designed several other superchargers and modifications to superchargers in use today. His goal was to offer V8 power, easily installed, in a reliable performance package at a reasonable price of $4,000 or less. I think he lives in Colorado Springs, CO and is being marketed out of Western Australia. One of his superchargers was engineered for motorcycles. He talked about his own Cherokee and the same supercharger on it, and how he always had to grin when he'd beat a muscle car off the line at a traffic light. I have the stats on that supercharger somewhere. He'd said that other superchargers on the market had trouble integrating into the stock electronics systems (gauges, incorrect trouble codes, fuel delivery, and others). He was certain that the technicians he'd worked with had solved all the mating problems that others had. Superchargers make horsepower from the get-go.
A friend I wheel with has another popular supercharger on his Rubicon and it is pretty impressive. He has to carry extra gas and does have other problems.
