Apparently I posted this question in the wrong section...so will try here. I'm looking to do an upgrade to a Magna supercharger. Would appreciate some general feedback if anybody has done this installation. I.E., ease of installation, horsepower and TQ gains, any negatives, etc. Thanks in advance!

 

before Touching The engine Do some Modification To The Tranny
Add Bigger Transmission Cooler

do you have 6.0 or 6.2?

 

I have a 2009 Hummer H2 and I put a brand new l9h engine 6.2 L with a Magnuson supercharger in it it works great I also put a whole bunch of high performance parts together when I rebuilt my transmission the 6l80 now the car is coming up to right about 547 horsepower 554 ftlb of torque

 

That is all great, but avoid tacking on to the end of OLD AZZED Threads to comment. This one is from darn near EIGHT YEARS AGO! READ: Old Threads/'Necro-Bumping'

Instead, offer up more details and some pics in a New Thread.
