the KB or Whipple are far better than the rosh charger (roots).

Opcon Autorotor (1990)
In 1990, SRM formed a sister company named Opcon Autorotor. This company was formed specifically to develop twin-screw compressors for use on internal combustion engine applications. With the vast knowledge and history of SRM, Autorotor used a later generation D-profile rotor design. By 1991, Autorotor signed an exclusive agreement with Art Whipple of Whipple Industries, which had already been producing supercharger systems using the Sprintex supercharger. This relationship was a tremendous success and quickly helped put the screw compressor in the automotive market. By 1992, the Autorotor compressor had adopted the name “Whipple Charger” which is still used today.

In the early 90’s Whipple Superchargers was over-burdened with building “systems” that they decided to only concentrate on General Motor vehicles. Whipple then agreed to supply Kenne Bell the “Whipple Charger” compressors for use on Ford applications.

I would not be able to buy a whipple SC for my 2001 mustang directly from them. the saleen series IV SC is a whipple, so I would have to get that. Whipple only offers them for the 03-04 cobra, 05-06 mustang, fort gt, and the new shelby gt500.

This is utter bs. In reality you will be hard pressed to even tell the difference between a KB and whipple without opening the hood, espcially on a 2v GT, and certainly on a stock bottom end.

People who own KB blowers seem almost fanatical about KB, but I think it just has something to do with spending twice the money everyone else did for the same results

Both use Lysholm internals. Both are so equivalent that there will be essentially zero difference in the 2. If i got one of the 2, id probably opt for Whipple.
