Whipple
 

A friend of mine has been offered a brand new Whipple supercharger from his local dealership that was ordered incorrectly. They have told him cost plus $100. He is trying to figure out what their cost would be. Any ideas or comments would be appreciated. The Whipple was ordered for a 2008 GT/CS but they told my friend the 2008 is different from his 2006 GT. THANKS!!
