I was woundering what real HP outpout gain you get with eny given super charger for a 5.3l. I would like to get one someday. Thanks.

 

I'd say 110-120ish from the supercharger alone, also depends on #s of boost

 

ok cool thanks for the numbers.

 

Here are my dyno numbers. From the bottom up is stock, Then as shipped with Magnuson supplied superchips tune @ 6 psi.
Then well after the Maggie warranty was done and my tranny let go 40k later I had it built up and Dyno tuned with a single size pulley drop @ 7 psi.

Dyno Chart

 

my bone stock 5.3** with an out of the box procharger made 440 to the wheels.

**with supporting fuel mods and cat-back exhaust

 

my procharger made 340-350 @ the wheels

 

depends on how deep your pockets are as to how much you'll make in all honesty
