Roots and positive displacement are the same style. you are thinking of centrifugal i think. And as far as tuning, give blow by racing a call. They are pioneers when it comes to the m90. Tell them Irish sent you
Is the Roush M90 supercharger the same one that the X-Charger uses? I know the X-charger uses a Eaton M90 supercharger but not 100% if they are the same one
Same basic unit I'm sure, the M90 has been used on many OEM and aftermarket cars. I believe the Roush uses there own design housing though. Roush and Saleen both used to use the M90 SC in there kits but the Roush system made more power due to the intake manifold/intercooler design being better (99-04 cars). There have been changes in the design over the years as well I think they use a Gen IV blower I could be wrong.
