HUMMER H2  

Consider this, you could install one of those powerdyne, or vortech, or procharger, compressor wheel units that does some boost but NOTHING like this, this is REAL boost.

Magnuson makes a solid unit but it is a very invasive installation with only slightly more gains than this option.   

The single best performance upgrade for your H2 that money can buy!

POWER FELT! The HP and TORQUE enhancement at low RPMs and throughout the RPM range and through every gear is beyond impressive, this supercharger is what the H2 needed rolling of the lot. 

You will wake that HUMMER up with power; you'll absolutely love the fuel savings now that your power to weight ratio is where it needs to be; and your H2 will be the fun monster to drive that you hoped when you bought it. 

I've owned 4 supercharges in different vehicles, they make the difference, but this unit in the H2 is the most impressive  improvement of any of my vehicles. 

This unit has about 3000 miles on it... My H2 was used to pull my boat and I drove it 5-7 times two winters ago until I listed my H2 for sale. I put the H2 back to stock and now I have this nearly new whipple supercharger. Google these, or ebay, or wherever you go, they are $6000-$7000. 

This kit should have nearly everything you need. Please note like most every performance upgrade there is likely a hose or a clamp or something extra needed, but the unit and tensioner pulley, hoses, belt, all bolts and brackets are all there.

You will not be sorry you made this performance change... Hands down the best thing to add to your HUMMER.

Denver performance truck shop,  Five-R-Inc,  can install this for $1500-$1800.
