What do folks think of a non intercooled low boost s/c? What type would you go with?

This is exactly what I was talking about when I created this thread. I know the dynamics of a SC vs a TC when compared in different cars. I'm interested in the best fit (if there is one) for the BRZ/FR-S. I'm thinking a low boost SC would be the safest and most natural bet for this car. I think a simple 30-50whp in this car would totally transform it.
As far as the type, I'm not sure. Would a centrifical s/c be lighter and more compact than a roots s/c? Also a centrifical s/c wouldn't require any kind of cooling.
I'm interested in the civic SI's compression ratio. If I remember correctly its very high. Not sure its it's 12.5, but its a 2.0 L 4 banger with 197 HP. The older one is atleast. I wonder what people's experience with charging that engine is.
EDIT: the 2007 SI's ratio is 11.0. Heh looks like they jacked it up in the BRZ to give it that extra torque.
