whats the difference
ok i hope this doesnt sound to stupid but, what is the difference between:
1:turbo chargers
2:super chargers
3:blowers
and what is better?
cheaper?
thanks

RE: whats the difference
No stupid questions brother, if you don't ask, how do you know.
All refer to forcing air into the engine.
Superchargers us a turbine run with a belt
Turbo chargers us a turbine driven by exaust gas
Blower usually refer to turbo's but can be slang for any forced air system.
Because Turbo charges run on gas they tend not to get up to speed until the engine is at higher RPM's thus there is "lag" while you wait for the engine to spin high enough to spin the turbine to force the air. In a supercharger the turbine is spinning all the time because the turbine is spinning with the engine and thus power is more consistant AND is avaliable at all RPM's. However my understanding is that modern technology has eliminated much if not all turbo lag so there is little difference between the two. I believe cost is about the same between the two my choice however would be the supercharger.

ok so if i can ever save up the money, what would be the best bet for a 2003 3.8? all my friends say get a V8 but i save alot more gas running a V6.
thanks again

RE: whats the difference
The only stupid question is a question not asked. 
Turbochargers: They are exhaust drivin turbines. They are more efficient than superchargers in most cases at mid-high rpm, but can be more efficient at low rpm. If you want high rpm power, this is the way to go, turbochargers anihalate superchargers in high rpm power. A turbocharged engine will also get better gas milage than a supercharged car of the same specs.
Superchargers come in 3 varieties:
1. Centrifugal: These are the easiest on the engine & offer the most high rpm horsepower, but lack the ability to produce boost in low rpm. The high rpm power is still lower than what the turbocharger produces at high rpm. Very efficient
2. Roots: These superchargers are the least efficient of the three. They produce the most power in low rpm, but they are horrible at producing mid - high rpm power. They also generate lots of heat. Stay away from these.
3. Twin-Screw: These are the best superchargers for all around power. They produce power from low to high rpm. Not as much low end power as the roots, but very close & not as much high rpm power as the centrifugal. Pretty efficient.
A blower refers to a supercharger. A blower is actully the roots type supercharger, but people often call all types of superchargers blowers.
Superchargers are cheaper. Twin screws are pretty expensive. Single turbo kits are priced allright, but I don't believe in single turboing a twin bank engine. Twin turbo kits usually are the most expensive.

RE: whats the difference
so a Twin-Screw supercharger is the way to go?
best all round preformance and cheaper than a TT..right.....

RE: whats the difference
also turbos are usually more money but generally yeild more HP. These babys can run quite expensive (can be around 3000 give or take a thousand or 2) which is why they call nitrous the poor man's super/turbo charger. Becasue it can give you 100 extra HP on a nearly stock engine for only 500 bucks. Just letting you know these things can be expensive and there are other options easier on your wallet.
