well im not sorry anymore cause thought i was right in my first post and as it turns out i was. i still thought that i had heard someone made a warranty friendly supercharger and ROUSH is it. look at this link.
ROUSH Performance - About The Company no wait you will probably be to lazy. just like you didnt call to otain info even though i provided you resources. so ill just paste the relivant paragraph. here it is....
The ROUSHchargerTM, a supercharger system, could be viewed as a microcosm of the entire ROUSH Performance line. Due to the engineering and quality of the product, it is the industry’s only aftermarket supercharger that continues the factory drivetrain warranty on the car, and the only one to carry a full 3 year/36,000 mile warranty (see web site for details). In fact, when installed on a stock Ford Mustang on Spike TV’s "Horsepower TV" program, the hosts basically claimed that in more than 1000 television programs they have shot using thousands of products, "this is the best engineered product, the easiest install, and the most thoroughly written instruction manual we have ever used on the air."
