Well, now, we can't let the Germans take the title of the world's most-powerful H2 - that just wouldn't be right for such a distinctively American vehicle. Fortunately, Indiana-based Lingenfelter Performance Engineering will install its fierce twin-turbo 427 package into any of GM's full-size SUVs, turning your H2 into a 700 HP monster. Yea, that's the same peak power as the Geiger supercharged H2, but with a peak torque of 740 lb-ft and a nearly flat horsepower curve (note that it produces nearly 500 HP at the rear wheels between 4100 and 5700 RPM), it's likely faster (indeed, a slightly lighter Escalade EXT equipped with the same engine does the 0-60 MPH sprint in only 4 seconds). It's less expensive, too, with the package costing less than $60,000. You'll need to supply your own H2, but the whole thing still comes in at about half the price of the Geiger H2.  The 28" wheels aren't included at that price, but maybe your money is better spent on the Raytheon thermal imaging system that LPE offers.
