The left picture is a roots type supercharger which can be broken down into a twin screw supercharger, they are better for the low to mid torque ranges and make power almost instantly and constantly. The pro charger is a centrifugal type supercharger which is basically a turbo except it is run off the belt and not exhaust. It makes more power towards the high end range and is te easiest of the two for installation. The centrifugals do suffer a bit of lag but not near as bad as a turbo.

Twin Screws also suffer from heat soak issues. When you see a race between cars putting down the same numbers the centrifugal car almost always wins because they continue making power all the way through the power band.

Also from what I understand centrifugals are more street friendly

Depends on what you want. Roots/PD style=instant power. Centri has to spool up but will make more peak power. Then you have a turbo which is the most efficient, properly sized will be in full spool pretty quick and will not run out of power on the top end. Also does not rob power to make power.

This.
I have a research paper on turbo/SC that includes a paragraph or two about Positive displacement and centrifugal superchargers if you're interested.

I will say that almost nothing in the world sounds better than a screaming M112 on a Cobra/Lightning. The KB/Whipples sound great too as do some of the other power adders but NOTHING sounds nearly as good as the Eaton stuff...
