Got to be the Supercharger... useable power regardless of what you are doing and the cheapest of the two... Turbo has the "dreaded" lag (foot to the floor, car moves ok, and then WHAM.. it takes off) - even with the most modern installs... i.e. with a Turbo, you're crawling some rocks and need to give it some gas at some point BANG Turbo kicks in = WTF & OMG (depending on your setting between 2000 - 35000 RPM) and you get what you didn't want... quick moves!..
The supercharger gives a little less power, but it IS useable power... it's there through the rev range - ALL the way through.
AND.. Turbo's WILL fry and may even fry your engine.. in a previous life I had some High performance cars built at the factory with Turbo's and they did all let go.
I dunno about the US, but where I'm from (Scotland) it's not too warm... at night after a hammering my Cosworths (use Google) you could lift the hood and see the Turbo glowing red hot... and I mean RED HOT... you won't have that with a Supercharger. (And it takes less space under the hood!)
Nearly bought a supercharger for my Porsche.. but I got rid of it and bought a HUMMER.. never looked back either!!!!
Supercharger or V8 H3... same result!
