I have a 2005 Black Hummer H2 SUT and what is better from experience, a supercharger or a turbocharger.

depends what you want more power-> more gas consuption then go with supercharger, more torque-> shorter engion life (do to the air being forced in at sucha high pressure) go with turbo charger.
BTW wrong forum!!!!!!!!
heres where you should post it

Both a turbo and a supercharger will shorten engine life because they both pressurize the cylinders more than natrual aspiration. A supercharger works all of the time because it is connected directly to the crankshaft, where as a turbo is driven by the exahust and only creates boost when needed. A turbo can be fitted with a waste gate to regultae total boost pressure, where as I don't believe a supercharger can be. Because the turbo is powered by the exahust, there is a lag between the time you put your foot into it and it builds boost. This lag is noticeable, but predictable. A supercharger has no lag since an increase in crankshaft rpm directly affect the supercharger speed and boost. A turbo will create higher exahust temps because of the restriction of the turbine in the exahust sytem close to the heads. This extra heat must be dealt with, or critical engine components may melt, or cause a fire. Typically proper placement in the engine bay, heat shields, and a moderate boost level is all that is needed.
I would suspect a turbo could provide better fuel economy than a supercharger because you can drive a turbo with little to no boost and basically have exactly what you have now with the same fuel consumption, whereas with the supercharger you have boost all the time and therefore extra fuel, to maintain the air/fuel ratio, all the time.

I'd agree with 99.9% of that with exception to the Magnachargers. I installed one on a LS1 and it was amazing. You would never know it was there.... until you put your foot into it.
I would never add one to my H2 though. I would be seriously afraid to recloate the air intake when I was fording water/mud.

I have the Magnuson radix supercharger and wouldn't change it for the world. Not only is it a hell of alot more fun to drive but I picked up 2 mpg too.

Tim could you give me a link and how much horsepower does it offer?

Bob,
I had it painted to match my truck, so not too shiny. Did get all the brackets chromed though.
Gorilla,
Here is their site and install pdf.
www.magnusonproducts.com http://www.magnusonproducts.com/pdf/manual02.pdf I have the s/c, Allen Nelson tuning, ceramic coated headers, throttle body bypass, Airaid cai, and Gibson exhuast and dynoed @ 508 at 6lbs. boost in 75-80 degree weather. Getting ready to go to 8lbs., 90mm throttle body, LS7 Z06 cam, 918 springs, and methanol injection should put me over 600. Trying to find someone that can change this thing to selectable 4 wheel drive with the new Allison 6 speed.

Thanx for the links and I might buy the magneseum supercharger and the numbers look legit though 6lbs of boost makes 508hp that seems high for that little boost. BTW what is the most boost an H2 can handle without it being dangerous because I seen little v6's with 20lbs of boost on pump gas. Hope I'll get the same results as you.

I was told not to go to 10lbs. I am gonna be at 8lbs. soon so I'll give you an update. If you do get one, if you are looking for performance then go with Nelson or compatible tuner not the one that comes with it. I believe that alone is around 30hp.

I had a problem with ebay a few months back, cause i lost about 6k on a turbocharger for my viper and it was cracked. I never use ebay for anything over one $1000 because I dont trust it.

If you want to find a decent used one try
www.performancetrucks.net . I got mine off there for $2000 in like new condition. It will be the same unit as for a Chevy truck and you'll just need like the intake tube and a few other things.
