RE: Roots blower vs Centrifical
Don't waist your money on a roots style blower.Why do you thinka lot ofthe 03-04 Cobra guys change out to a KB, (twin screw style), from the factory Eaton, (roots style),when they want to make BIG power?
Go KB or Centri.

This will explain the differences better than I can tell you. That is if you can get through all the KB propaganda.

twin turbo would be nice as well
but the spool kills you, by the time you spool up your goin 100+ lol

Thats why you get one smaller turbo to spool up quickly, and one big turbo to take over at the high end!

RE: Roots blower vs Centrifical
Some roots type blowers could possibly make the same power as some centri's, but in most case its roots<centri<twinscrew<turbo... you get what you pay for... But the centri looks cooler, is cheaper... and get good power out of it.

Roots is pretty much instant power, where centriFUGAL (not fical, lol) needs to spool, similiar to a turbo. they just make power in different parts of the powerband.

Our 2v's need the HPup in the high rpms. Aroots style (KB) isgonna have boost @ idle & run out of boost @about 4000 RPM's. Nice for wheel spin & short shifting but thats about it. Roots S/Crs loose efficiency in the high rpms.A Centrifugal S/C like a Procharger is a much nicer fit for the 4.6's. They dont start making boost till about 3000 rpms.
Combine a centrifugal S/C with a good dyno tune & you will feel it pull off the line right past 6000 RPM's. Only thing keeping you from making power even higher is your valves will start to float & mb bend a rod. A dyno tune will give you the torque on low rpms & the S/C gives you the HP past 3000 rpms.

As far as the rest of your statement is concerned, I'll take it with the same grain of salt.
