Kinda strange that SM isn’t casting a Mopar Blower Manifold

Its usually all about "supply and demand". For the forecasted demand they may have or perceive, they can likely buy the existing manifolds at a cheaper cost than investing in tooling for their own. This gets them into the market. Once demand reaches a higher (reasonable) volume, they might change their manufacturing path and make their own manifold.

Does my duster NEED a blower? No. Will I be making a mental note for next Black Friday? Absolutely.

If you do get one for your Duster, you will never regret it as long as you don't put a little to much boost into it. Probably more power from a turbo but more cool factor with the Roots blower.

I’ll never disagree with you on the looks factor. Always wanted a roots blown car. This makes it slightly more feasible.

The nice thing about Roots supercharging is o plumbing, instant boost, massive low end torque without the extra costs of a hair dryer system, supercharger or turbo. Even more so needed if the pressure and heat rise high enough to demand an inter cooler.

With the Roots supercharger, if cooling is needed, a water cooled system can be set up under the blower and simple plumbing is used. On a turbo or centrifugal, the plumbing to and from the internet cooler can be a big PIA and pricey.

What I like about pressuring an engine is that even at modest low levels of boost, the returns are really good. 9psi is a wonderful thing.

There is some fella that goes to the Bellmore meet and is awfully proud (to the point of turn off) of his roots small block cranking out a claimed 1,000.
