the following is what i have read. i don't have any experience because i don't have either a supercharger or turbo....yet.
SUPERCHARGER
*advantage*
- no turbo lag
- instant boost
- almost maintence free (only need to check belt and oil leakage)
- more torque upgrades in lower rpm range
- no time wasted to warm and cool down
- JRSC = 50 state legal
*disvantage*
- low boost
- cannot upgrade as high as turbo
- no intercooler
- no blow off valve (if you're into that thing)
- not many brand and models to choose from
- uses power from the engine to run the supercharger
TURBO
*advantage*
- parts everywhere!!!!!
- you can custom build any set up you want
- more boost
- intercooler
- blow off valve
- many turbos have improved on lag problems with design techniques
- free power! - using exhaust, not belt
*disadvantage*
- turbo lag
- need to wait for turbo to speed up before gainning boost
- once you let off the gas to shift, blow off valve goes off and you have refill the pipes with pressurize air before power can be gained
- depending on set up, due to the lag, not really meant for street driving
- have to let turbo cool when stopping the car
- a lot of piping for air and oil
- they get really HOT
- most of the power and torque gains are in the upper rpm range
- many custom set up are not state legal
I may have missed a few points or said a few things wrong
feel free to correct me if you wish to do so.
as for me, i'm going for a JRSC with 6 psi.
i found one for 1700 and i'm going to see if he still has it for sale.
the reason why i'm going for this set up over a turbo is because...
- smog legal (yepee especially since i'm in CA)
- my engine can handle 6 psi with little mods
- low maintence
- a lot easier to install
