From the web:
known cons
Turbocharged: Spool up time, boost spiking.
Supercharged: Parasitic drag.
*heat is detrimental to both.
known pros
Turbocharged: Crank up the boost!, after turbo lag....BOOM! outta here, the psSSSHt! sound (blow off valve, babY!.
Supercharged: Instant mash on the gas HP, no oil line needed, SC whine! (VVVWWWWWWHHHAAaa!)
Supercharger gives a nice gain in acceleration and power through the range, but once you have a big "phat" turbo kicking in they dominate everything
my dads last car was Supercharged and my car is Turbo. The supercharger gave power through all the revs but the Turbo is just much more fun lol
