blah blah blah. i really wish people would stop saying turbo lag when comparing the 2. there's little to none if you get the right size turbos. besides, you can also have SUPERCHARGER LAG too if you get a centrifugal type blower.

right, but the SC has parasitic loss due to being belt driven...so it technically uses some of the power that it makes.

But you still have some lag.
Another advantage to S/C is that you have a smooth torque band... what I mean is, with a S/C the higher the Rpms, the more air its gunna flow, but with a tubro, you need to wait for it to sool up and THEN you get the power. I dont mean turbo lag, Im talking about chitty performance at lower RPMS where bigger engines opperate. This is why you see alot of turbos on hondas and stuff... the rev higher than big V8 engines.
Another big problem with turbos is the heat. While a s/c make heet, the turbos get a little warm from all that exhaust gas, which in turn will heat up the intake side of things. thats why you need what is called an intercooler (too cool the air). Because of the need for an intercooler and having to rerout exhuast, you need to do alot of plumbing, so it enerally makes things very complicated.
What we posted here is just a basic explanation. There are many different types of superchargers... some that are clutched, some that pump air like a turbo, others that pump air with twow rotating "drums" (the kidn you see in top fuel dragsters)

And on your previous post, what does N20 have to do with turbo lag?? Sure, I have heard of people using it to eliminate lag, but that is not the only way. You can run 2 different size turbos, or you can just get the properly sized turbos for your application.

Yep for example, the S/C on the Ford GT sucks off 125hp of the power it makes in parasitic loss. If I remember correctly the amount of loss is roughtly 20-40% of the total HP that the S/C adds is lost through parasitic loss. Umm...that doesn't sound right..but you get the picture.

Then you must be running a turbo the size of a quarter?

sure you can what if your turbo is at full boost when your idling? lol jk

a deisel can't even get full boost at idle. and it has no TB. wide open all the time. you increase rpms by adding more fuel

RE: Diffrence between S/C and Turbo?
Lets put it this way, I've seen plenty of supercharged cars from the factory do all of the work to take off the supercharger unit in favor of a turbo. But never the other way around.
Superchargers are good for ease of use.
You can build boost off the line in a turbo car using brake boosting on auto cars, stutterbox, or other form too so theres really no disadvantage off the line. The top end isn't even close, a big turbo just doesn't want to stop pulling.
