A top speed of 250 km/h: The world's fastest Hummer comes from Geiger Performance. The leading European tuner of American automobiles equips the SUV with a 7.0-liter V8 supercharged engine delivering a maximum power output of 700 HP (515 kW) and a peak torque of 904 Nm.
Added to that is an exclusive Geiger Performance luxury equipment package with 28-inch chrome wheels, sport suspension, high-performance brake system, pearl-effect special paint and an exclusive interior complete with multimedia system.

To make the Hummer H2 the fastest of its kind the specialists at Geiger Performance replace the standard 6.0-liter engine with a V8 from the current Corvette C6, albeit with a bored-out displacement of 7,011 cc. Numerous additional modifications such as precision-machining the two cylinder heads, the installation of a sport camshaft and a reinforced valvetrain are also part of the Geiger Performance power treatment as is a cogged-belt driven supercharger with high-capacity intercooler. A fully stainless-steel high-performance exhaust system with high-performance manifold and metal catalysts completes the engine conversion.

With these modifications the supercharged eight-cylinder engine produces a maximum power output of 700 HP (515 kW) at 5,500 rpm and a peak torque of 904 Nm at 4,260 rpm. Power is transferred to all four wheels via a modified four-speed automatic transmission. Despite a curb weight of 3.1 metric tons the Hummer H2 7.0 Kompressor from Geiger Performance achieves performance on the level of a purebred sports car: The sprint from 0 - 100 km/h takes just 6.5 seconds, top speed is electronically limited to 250 km/h.

Performance such as this necessitates numerous Geiger Performance modifications to the suspension. Immediately eye-catching are the king-size 10Jx28 forged one-piece chrome wheels with size 325/35 R 28 tires.

It'd probably be a lot quicker w/o the 28's.

Wow, that's a load. Link to LPE's 427TT with 700hp (it used to be 750 ) on the dyno. This truck has less torque.

Very difficult getting any answer out from the folks there at Geiger. My future mod is the MagnaCharger but can't find a shop at my location to do the install.
Nice H2 but wouldn't want my H2 to be lowered and/or have the big 28" rims like the Geiger. Just my personal preference.

that is OUT OF CONTROL... i wanna see that thing race some other hot cars.. like a ferrari or something.. videos please!
