Sure it does. It stuffs more air (and therefore fuel) into the combustion chamber and therefore delivers more power, regardless of rpm. A turbo can boost hp by a substantial percentage, that's not something I'd want to do to an engine that I wanted to last a long time though. It's a tradeoff like most others...can't get something for nothing. Folks ask me why I don't have a turbo on my Corvair, and my answer is "because if I had it I'd run it wide open all the time and the engine wouldn't last nearly as long", due to stuff like much larger and many more "destructive magnitude" bending moments on the crankshaft, for example. Heat dissipation would be an issue on full power climbout or at low speeds, but up high that probably wouldn't be the issue that would kill it. Having said that, our three family cars are turbocharged. They have proven to be very powerful and very reliable, and I love driving them all, so the bottom line is do what you like. Revmaster's been selling turbos for many years, and apparently they work quite well. Others with actual turbo experience are welcome to chime in...
