Here you go..What I like most about the M90 on my Sport is the increase in low to mid engine speed torque. That would be the only reason I would add a supercharger to my 2003 Centennial. Have you seen a torque curve for a 4.6L with the Vortech and modest boost?
Will you have to eliminate the mechanical radiator cooling fan?
I purchased a stock 2003 Aviator timing cover that appears to have the 3 bolt tensioner mount.

I also purchased the stock Aviator bypass assembly.

Problem is this is misleading . .the KB and the vortech make so much more power at lower turbine speeds,when you try to keep a even boost level of 11psi that you slow the KB and vortech down so slow they suffer in the lower rpms.especially the vortech but once you reach speeds at which they start producing power they both out power the Eaton . .also the vortech was tested on a short runner manifold that doesnt help it all,they have tested it with other manifold setups and produced much better torque down low..the graphs are in a different article . .also if you look at the graphs were they compare them at boost levels of 16 psi the eaton really fell off
Most people who run the KB or vortech are looking for more boost so they speed them up which helps them down low and shines up top..
With the Vortech you can speed it up where you get all the boost down low and set a blow off to the max boost level you want..this sometimes cause the vortech to be over spun at high rmps if your not wanting all that boost..
The eaton or Kb honestly looks to be the best for down low and all around power..where the vortech and twin turbos tend to make much much more power mid to upper rpms
