Turbos have always been something i wanted to do, their is nothing like the torque hit when the boost kicks in.
Supercharger is great too, but I really like a nice quiet ride... Don't mind a racket at WOT.. but I don't want to have to scream to talk to a passenger.
One of my long term goals is a cross country drive..

Mark Stielow would be best to address all three types of engines, but he seems to like supercharged engines lately. The gas mileage depends on your driving. So, if you have your foot on the pedal all the time, then you might as well forget fuel economy.
What type of car do you have? For example, 67-69 Camaro's didn't have sound deadening in them. Will it be quiet as a Lexus? No! Even after you added sound deadener to the car. Actually, my dyno test are done with open headers. New cars have spent lot of time in the wind tunnels, while this didn't occur in the 60's.
http://www.clublexus.com/forums/car-...-few-cars.html Wind tunnels have helped improved the fuel economy, but I personally like the look of 67 Camaro with supercharger than any of the new car designs. I am degreed Engineer, but I do understand the compromises that you need to make. Take a few engineering classes and then you will understand that there is limits to these cars. I am interested in his E85 Project with Mayhem and the LS9, but I was told in 2008 that it couldn't be done at that time.
Another option is a big cubic engine LS engine.
