nope... air temperature depends on the intake, intercoolers, etc. The hot fumes spool the turbo blades and go right past them and out the back just like normal, the turbo sucks in the intake air and passes it into the engine. The air is clean and cool either way. The Super Charger is belt driven, just like your AC. Ever notice how much poer the AC takes from your engine? How about 20% on an average family sedan. Well the SC is more or less the same thing. It eats up power to rotate and compress the air. That does produce more power, but think about it. If your engine can take 15 psi of boost (being 100% reliable on the street) and that boost gets you another 150hp, the turbo eats up nothing and you get the full 150hp, while with a supercharger you might get 110hp, because the 40hp was eaten up by the SC itself to operate. On the other hands the SC is tied down to the engine and you get instant response and boost (Merc even has a feature to disengage the SC when its not needed at highway speeds under no acceleration). With the turbo, it depends on the volume of exhaust being pushed through it, so there is the effect called lag. Big turbos lag more, so its a good idea to go with twin turbos which are each smaller and spool faster but toghether provide as much as one big one without the giant lag.
Pick up a Turbo magazine i think last month or this one and they have a big article on this issue.
