which is better?more efficent? and overall faster? a supercharger or a turbo?

I think you will run into less problems if you choose the supercharger route. They both get you boost, I have seen both done and am personally supercharged, and I just think I have WAY less problems than the turbo guys...

2 Main Factors to look into
-Cost
-When Bost is Gathered


-Turbos will run you about 5k or so if you do the work, a supercharger will only cost you 3k. Eiether way after you are going to need to get your car tuned.
-Turbos are more for the High end horsepower, superchargers are for off the line boost

problems occur with everything. cheap stuff makes more problems.
lets compare...
s/c and turbo both can make 10psi
s/c will make 10psi at 4k-6k depending on s/c and pully and all that
turbo, the right one, can make 10psi at 3k, also if you have the wrong one (too big for example) may not make it untill 6k.
turbo's are more expensive usually.
cheap turbo=dead turbo-shorter life
cheap s/c-like a powerdyne=dead s/c and motor
power loss through pully to drive s/c
minimal power loss from turbo due to a little more backpressure b/c of turbo.
turbo's create more heat than a s/c, use a good intercooler and put a shield around the turbo.
you make more hp per psi from a turbo when put against a s/c

my vote was turbo

Positive dispplacemet blowers make best power right off the line(roots or screw). Roots are the cheapest and most inneficient and tolerate the least amount of boost for any given fuel octane because of their high heat production. Screw are like a more efficient roots blower, they'll tolerate more boost for the given fuel octane and produce less heat than a roots. Centri are more efficient than positive displacement, but only make peak boost at high rpm, this can be an advantage in a traction limited car since the power comes in gradually. They'll also tolerate more boost pressure since they boost past peak cylinder pressure rather than through it like positive displacement. You can make more top end horsepower for the same fuel octane, but low rpm and mid range won't be as strong. Turbos can be set up to start boosting at low or high rpm, and they have the highest efficiency. They'll tolerate higher boost for the given fuel octane and make the most power. They also don't require the crankshaft power to run that a supercharger does.
