they do the same thing. compress air going into the intake manifold.

a supercharger unless its hooked up to a centrifugal clutch is basically consistant power thru all rpm ranges but you sacrifice a lil top end to it.. its also only used on high compression engines..

a turbo spools up power and then releases it at a certain rpm and holds it. turbo's are for top end (high speed) power. its also used on low compression engines..

if you have a six cylinder or bigger, youd want to go with a super charger, but if you have a four cylinder, then get a turbo. the four bangers produce more pressure in the exhaust than larger engines do. and the more pressure thats built up, the sooner that turbo will spool up, producing more hourse power sooner.

wtf gave you that idea?

the only reason most 4s are turbed is because they dont make enough compression to be super charged... hence low compression engines for turbo's not becuase of the back pressure in the exhuast..

hah, were do you get your information from, the bottom of a cracker jack box?? shitass. Turbo's are used on 4 cylinder engines to boast power and torque without having to increase the size of the engine, as well as still be very conservative on gas mileage. It has nothing do do with they work better on 4 cylinders than 12 cylinders, because there's a number of 10 and 12 cylinder engines that come equipt with bi-turbo's, or even v6 and v8's, Lotus Esprite V8 TT, Audi A4, A6, Mercedes CL55 V12 bi-turbo, buggati EB110 v12 quad turbo's, not to mention supra's I-6 Twin turbo, skyline I-6 Twin turbo. It can go on forever, size doesn't matter for shit. don't post shit that you can't back up with proof, especially in tech area's, cause it throws off people looking for real answers. fartsmeller

the amount of lag depends on the size of the turbo. a small to mid size turbo will kick in pretty early but trail off and create alot of heat in the top end, a larger turbo will have a larger boost threshold but will give more power, and run cooler. one example of the lag vs heat comprimise is the air cooled porsche 993 turbo

turbo takes air in compresses it, and thats pretty much how it works w/out gett ing too complicated .....ive driven my friends turbo volvo 740, u could feel the turbo kick in w/the boost, and even though its a kinda weak car, u could still feel the boost, which made it feel pretty nice, but since its a not too serious of a turbo, i think u dont really feel the lag as mcuh, cause when theres not as much to be lagged?????? correct me if im wrong

turbos are generally for higher RPM's, where superchargers are generally all around

A turbo is like a motor. The motor (turbo) has a fan that pushes air into the air intake. The motor itself is driven by exhaust gasses that force it to spin. Since the turbo needs the gasses to turn, the engine must first be under load. (petal to the metal) that,s where the lag comes from. Hope I didn't over simplify this too much.
