You could write pages on this and there is a ton if info out there, but to start... Turbos use exhaust flow to build the forced induction and can therefore have "turbo lag" where you don't build boost until the upper RPMs(not exactly the most fun on the street). Supercharges build boost through a belt driven off the crank and if you have a roots blower the boost will be much better down low. A centrifugal supercharger will be similar to a turbo.Turbos also will most likely have more plumbing to deal with since the headers feed it.

In a nutshell, they are the same in principle. Supercharger is belt driven, Turbocharger is exhaust driven. A centrifugal supercharger is literally a belt driven Turbocharger.

-Supercharger will be less expensive to buy, easier to install and less to maintain
-Turbocharger has almost no parasitic loss and will make more all out power
-Supercharger will suck up about 15% of the total engine power to make its power
-Turbocharger properly sized for your application will have very little turbo lag and will get into boost faster than a centrifugal supercharger but slower than a positive displacement supercharger.
-A turbocharger will be happiest behind a stalled automatic where you can spool it up on the transbrake and launch at full PSI.
-On a 5.0 Mustang, ANY supercharger or turbocharger setup is going to be limited by the block. When you start getting up into the 500rwhp range you are in danger of cap walk and the block splitting on you. Modulars have the same limitations but its the rods that can go in those, not the block. Modulars actually have to keep it a little lower but rods are a LOT cheaper than a Dart block lol.

I could go on and on... honestly if you are asking "what are the pros and cons" you need to read read read. Use google, buy some books, go to car meets and talk to multiple ppl and just educate yourself. Your first blower especially for a 5.0 really should be a basic Vortech S trim supercharger. They are cheap, reliable as hell, easy install and will make as much power as the stock block can take.

100% agree with scotty. I personally think that in almost all situations if the money is right, Turbos will be a better choice, that being said I've driven a lot of turbo cars and few SC ones. A Turbo charged setup will give you such a flat torque curve (once it spools)

I have not personally used it but I have seen it installed and know how it works. What exactly is your question? You can get a bunch of info on it by just googling around.

Is it something that is a good power adder. Is it hard on your engine like nitrous is.

Meth injection just cools down the air charge. It isn't a power adder. Its great if you don't have an intercooler or if you are just looking to lower the temps even more though. Combined with a power adder meth injection can add power just because of the cooler air.

Methanol alows you to up the timming on your motor' it raises your octane levels.

It allows higher boost levels.

I guess in a roundabout way you could call it a "power adder" lol. Sort of like you could call any bolt on a power adder. To talk about it in the same way as a turbo/supercharger or nitrous is not correct though. Hell, a lot of guys run a small nitrous shot to cool down the intake charge vs the methanol.

The only difference is that nitrous oxide could lean out the mixture meth will add fuel

Just imagine what meth does to your engine internals
