Engine Turbo Supercharger SAME

Like many things this is very difficult to answer without knowing what the intended application would be. Here are some characteristics, good and bad.. There are 2 types of supercharger- centrifugal (paxton,vortech, procharger)and Positive displacement/Screw supercharger(whipple, eaton, kennebell, BDS, jackson racing) both operate differently. A centrifugal is a belt driven turbo -has a linear boost (an example from a dyno run, 5.0 mustang - 2lbs@2000prms, 4lbs@3250, 8lbs@5250 and 12lbs@6250rpms) less off idle/low-mid rpm boost than a screw/PD blower, less mid rpm boost than a turbo, good if you already have: enough low-end torque, traction issues of the line and less stress on the drive train (TQ breaks stuff not HP) - easier to install than a turbo system or screw/PD blower - has a belt that WILL slip or break with age/use at one point or another - thermally more eff. than turbo or screw blower, does get heat soak from turbine or engine like the others. - can easily have an intercooler installed at a later date like the turbo A screw type supercharger - instant boost, if you love torque/throttle response it's #1 - more complicated to install - usually heavier/ harder to package(hood clearance) - has a belt, that will need servicing but last longer than centrifugal superchargers - harder/more$$ to intercool, especially later on - eaton superchargers can have boost valves that lessen parasitic drawn when it isn't need(saves fuel) - screw blower noise Turbo equipped engines experience turbo lag/ delayed boost (especially at low rpms, just of the line), with new technologies (VNT)/turbo designs/materials(ceramic/titanium turbine wheels) this is lessened greatly,BUT is still there. In certain application ( already have traction issues, enough low-end torque) it might be a good thing. A turbo system has less low end torque than a screw/PD supercharger. - most veristal, with wastegates, boost per gear limiters - best fuel economy - most complex with exhaust manifolds needed, oil lines, wastegates, bov, turbo timers $$$$$ - easy to package versus screw chargers - most options to customize, turbine/compressor housings avail. single/twin/quad turboes - if kit sized for high horsepower, can have a late/fast boost rise/spike in TQ, can be fun "sudden surge" but can be hard to control (I.E. orginal turbo 911) - turbo noise Tuning a supercharged engine correctly requires less time then tuning a simple turbo charged installation. The computer mapping is easier due to the predictability of the supercharger due to the smooth perdictable boost.
