Dodge Magnum wagon owners

I don't have one but my friend Tom has a silver 09 Magnum and had a supercharged installed in it just this year as he said he did it because it wasn't a fast as his twin turbo Supra was. Tom is either 88 or 89 years old and been into cars all his life. Now he says, he may put all that has been done into a 6.0 and replace the 5.7..
Crazy ol'people, ain't they!
