Even though the centrifical superchargers cost less, most of my driving and competing comes at lower speeds...
Around the city and maybe the occassional track visit will still have me operating in the 0 to 100 MPH range...
With the said, the root style blower met me needs...
I had the saleen supercharger installed by a Ford SVT dealer that warrantied their work...
Love the performance!!!
Since I drive the 2005 GT w/automatic, any power charge I can get right out of the box will help me more than the power charge coming on at 75 MPH...
Get the root style, Kenny Bell, Whipple, Saleen, etc are the best choices!!!!!!
