Hi guys im over here in Australia and was just wondering if anyone has supercharged the h2 recently as ive seen other threads on here but they all seem to be a few years old.I have a 2005 6.0 litre h2 and have recently fitted a cold air intake and had a custom ecu tune which resulted in 300 rwhp at all wheels.Im now going to fit a magnuson supercharger and see that they do the 112 for the 6.0 ltr or the 1900 for the 6.2 ltr.ive spoken with magnuson over there in the states and they said I can fit the 2300 supercharger to my h2 and was just wondering if anybody else has fitted one recently and if so what size supercharger did you go for and were you impressed with the results.The 2300 supercharger is what all the guys over here fit to our 6.0 ltr / 6.2 ltr gm holdens.Was also going to do heads / cam at the same time thanks guys.

 

I like your license plate.

 

Can't wait to see pics of it when your done

 

I am currently installing the Magnuson TVS 1900 Radix supercharger, my Hummer has the 6.2L engine. I should be finished by Tuesday June 7, 2022. I will post pics and let you know how it's going. I can't wait to finish the upgrade.
Next I'm going to put the Kryptonite upper control arms and tie rods on, I'll take pics of that too.

 

i doubt you will see pictures as that post was from 2015. probably would have posted them by now.
