Roots type makes power from idle up, and stay liner in the power deliver all the way to red line.
Centrifugal force unit tends to come on hard around mid range and boost from there up instead.
The downside of a roots, is the TVS-2300 is about as big as it comes/ becomes a heat pump when over spun too much trying to make huge power, while a larger centrifugal force units can offer way more boost with less heat instead. So the TVS-2300 is not bad to about 650hp.
As for either unit when you start to approch 600hp and up, you need to a meth kit into the mix. The reason of this is you want an octane buffer in the mix so you don't end up with knock, plus the meth kit deals with the added pressure heat so every boost will give the same amount of HP. Hence even with lower amounts of boost and no meth kit, you start to heat soak the engine, and this ends up with a timing retard that causes less power instead.
To really bottom line it, if you are using such for road course driving, then the roots system. Here the power is linear from idle up, and allows you to use a lower gear with extra power to grunt out of the corner instead.
If you are using such for drag type strip instead, then the centrifical unit instead. At some point your going to get into heavy boost from about mid RPM up and in a drag strip type run, your going to spend all your time mid rpm up anyway to stay in the boost. O

As for either unit when you start to approach 600hp and up, you need to add a meth kit into the mix. The reason of this is you want an octane buffer in the mix so you don't end up with knock, plus the meth kit deals with the added pressure heat so every boost will give the same amount of HP. Hence even with lower amounts of boost and no meth kit, you start to heat soak the engine after a boost or two, and this ends up with a timing retard that causes less power instead.

At some point your going to get into heavy boost from about mid RPM up and in a drag strip type run, your going to spend all your time mid rpm up anyway to stay in the boost. On a road course type car, you almost have to play rev ranger, since if you are trying to grunt out of the corner, and get mid rpm boost before you are out of the corner, the boost hit will break the back end free to come around on you instead.
