turbo vs supercharger

[dj justice]

i was just wondering what the main differences are between a supercharger and a turbocharge

[92accordf20a]

A turbo runs of the exhaust gases to operate, exhaust gases turn the exhaust side propeller, which in turn turns the intake side propeller. A supercharger runs of the crankshaft by a belt, the belt turns the pulley, which in turn rotates the propeller. Turbos rob u less hp than superchargers but, supercharges have constant power. (meaning their always on, no boost lag)

and by that...supercharges put more strain on your engine....

i dont think they make s/c's for our cars anyways unless you get a custom one....but whatever...

boost or die

[92accordf20a]

i prefer a turbo over s/c any day, u also have to deal w/ slippage of belt, broken belts..

[91ACCORDSIR]

But... Id rather break a belt then blow and engine anyday

[92accordf20a]

either way whether ur boost 20psi on a turbo or 20psi on a s/c it's still the same engine.. It's gonna blow ne wayz...

overall superchargers put more strain ont he engine...ive had friends blow their 6g trannies....one of them happen to me on their 13th...yes 13th tranny and counting....wow they suck....with the Comptech S/C....and thats just at 6psi i think....

TURBO ALL THE WAY!!

that's the way 2 go..

super chargers make their power in a linear fashion, that means that the power curve is pretty close to that of stock. Superchargers work well for applications such as mudding trucks and low end torque machines. Depending on the application a supercharger is very ideal.

Beyond the obvious advantages of them, they are easier to install and require less components to operate properly. One of the easiest things is the fact that the fuel managment is simple because you don't have to worry about the variables involved in turbo boosting a car.

There are a 3 types of supercharges, centrifugal, twin-screw, and roots. Centrifigal would be something similar to the turbocharger setup, most of the time you see these on imports because they are mounted in the fasion like an alternator would be. Twin-screw are a very efficient design and work with two gears side by side compressing air (two screws). The twin screw is argued to be the most efficient style of supercharging. Roots is those big mean nasty looking things you see on funny cars and old school hot rods. They are terrably unefficient but who cares if your roots blower is robbing your motor of 3-400 HP when the end result puts you well past 1500!

There are plenty of good research out there, just type in the style of supercharger and away you go. I don't feel I need to go into the dynamics of turbocharging because this should be a known topic. Come do a search around the forum that I moderate over at home made turbo (check sig) and you'll find all you need to know.

I personally like turbos cause they are cheap, efficient, and make much cooler noises then a supercharger does (unless you like that constant whine... but if I was down for that then I would get a gear drive cam set - for my small block chevy).

hope this helps.

Thanks a lot guys that has been very helpful. I was actually asking for a friend of mine who wants to get the scion tc. He was debating between a supercharger or turbocharger. I myself might go turbo on my f22a1. Thanks again.

glad I could offer some assistance. Look around this board for turbo info or my board.
