Heavy Water: Geiger supercharges the HUMMER H3

Click above to view the supercharged Geiger H3 in our hi-res gallery
Mention the name Geiger to a physicist and you're likely to hear about the man who discovered the atomic nucleus and the meter that bears his name. To automotive tuning fanatics, the name refers to the aftermarket firm that turns lethargic HUMMERs into tarmac-chomping beasts. But we're not so sure the two are that far removed.
Geiger's latest project is another riff on the relatively (and only by comparison) "small" H3, tinkering with the truck's reactor core to pump up its radioactivity. The stock H3 comes with a 3.7-liter inline-five producing a paltry 239 horsepower and 241 little torques, though it is available with a 5.3-liter V8 which still only manage 300hp and 320 lb-ft of twist. Along comes Geiger to fit a supercharger to said eight-cylinder, boosting output to 423

This really needs a desert preferably with lots of dunes to really show its purpose. Altough most HUMMERs let alone these Geiger ones are probably going to live their lives in garages, on the school run and parked outside shopping malls.

Wow, thats an original comment practically cut and pasted from any Hummer thread. WTF do you care where someone drives it, if thats what they want to buy and how they want to drive it, that is their choice. Mind your own business and stop judging people.

@ Major Geek, I am going to throw the flag on you. Mobius did not make a judgement. I would read it as an observation that I would agree with based on my own 2 eyes. I have never seen a dirty H2 or H3. Actually, it sounds like you are the one being judgemental. Not judging here, just another observation:)

WTF do great racing (car) liveries of the past (usually associated with Porsche) have to do with Hummer???

Maybe it transforms into a robot named Jazz.

BLASPHEMY!!!
I get sick of tuners putting racing liveries on their vehicles in a lame attempt to give them some sort of cred. I'm sure these guys are European, probably German, since they're the most guilty of this sort of thing.

Wouldnt be surprised if this was somehow funded by our auto bailout money :)

Considering it says GeigerCars.de on the door I highly doubt it was "funded by bailout money." Use your brain.

it was sarcasm colin. A comment on the lack of oversight in all these bailouts. Like the fact that chrysler spent millions of the bailout money taking out adds to thank america.

Why? Why do this. Why are people wasting time making SUVs into sportscars?
Then build a sportscar...

I like to point at drivers of blinged out SUV with monster wheels and low profile tires. Once I get their attention, I laugh and point and laugh.....

Not enough plastic doo-dads, carbon fiber whatcha-callits or pin stripes... Just too subtle.

That's a pathetic time for all that power.
Compare to the 4800lb Grand Cherokee SRT-8 with 420hp and less torque - and a 0-60 run in about 5 flat.

couldn't agree more. with all that power the best they can do is 7 seconds 0-60?

this said nothing about an ecm reflash, I think that would make the time much better. Stock shift points are made for less toque and hp, where the SRT8 was designed and tuned like that from the factory.

...But the Hummer has that bitchin'-cool Martini graphics package

I never got all the buzz about the Hummer's off road ability. I was in an infantry unit for a number of years, and we stranded the H1 military version in the mountains several times. Thank goodness the deuce and a half could always pull the Hummer out and then outrun it back to base! And yes, it does seem sacreligious to have Martini and Rossi livery on this thing. I think of Porche 917s, 935s,936s, and lightweight Carreras. I also think of Lancia Rally and Group C cars. Up next is the Gulf liveried fill in the blank 5000lb SUV. But it seems to be the rage these days to look to the past for ideas. Sometimes it is good, sometimes not.
