man you really didnt read the article. he is injecting hydrogen into it. I am sure has done other modifications other than just dropping a duramax in a H2. The only think I dont get, he is pretty smart fellow , why did he bother to make a special harness and use the factory comp for the conversion, he can get get a microsquirt for 400 dollars and do engine management.
There is no mention of hydrogen being injected into the H2 that supposedly wowed the GM engineers two years prior to the article being written. It was just an H2 with a Duramax diesel bolted in, with a valve to switch to veggie oil after it warmed up. Conventional, and old tech. No reason for the GM engineers to faint over it.
Hydrogen injection is mentioned for the turbine powered H3, but that is nowhere to be seen yet.
Hydrogen injection is mentioned for the H1 that supposedly fell apart on him, but the claims are dubious. The hydrogen tank lasting 700 miles would mean it was a giant tank, or he wasn’t using enough to do anything.
Hydrogen injection is unlikely to do what he claims, anyway, unless you use a lot of hydrogen.
I think you haven’t read the article very carefully.
“Putting a diesel engine in the Hummer, however, required Goodwin to crack GM’s antitheft system, which makes it a pain to swap out the engine. In that system, the engine communicates electronically with the body, fuel supply, and ignition; if you don’t have all the original components, the car won’t start. Goodwin jerry-rigged a set of cables to trick the engine into believing the starter system had broken, sending it into “fail-safe mode”—a backdoor mechanism installed at the factory. (At one point in his story, Goodwin wanders over to a battered cardboard box in the corner of the garage and hauls out an octopuslike tangle of wires—”the MacGyver,” his hacking device. “I could have sold this for a lot of money on eBay,” he chuckles.)
Once he’d picked the car’s lock, Goodwin installed the Duramax and a five-speed Allison—the required transmission for a Duramax, which also helps give it race-car-like control and a rapid take off. After five days’ worth of work, the Hummer was getting about 18 mpg—double the factory 9 mpg—and twice the original horsepower. He drove it over to a local restaurant and mooched some discarded oil from its deep fryer, strained the oil through a pair of jeans, and poured it into the engine. It ran perfectly.”

This makes no sense whatsoever. Why not just buy a new Chevy HD pickup, which already has the Duramax and the Allison? Why go to all the trouble, hassle, and major expense with modifying the 15 year old H1 Hummer? Just double the mileage and power of the Chevy pickup, which already has what you want in it.
I understand the challenge with the old H1, but if he wants to show the world that he can double the mileage and increase the horsepower of a diesel, it makes much more sense to use the Chevy pickup. It’s already ready for his mods, and lots more people own them.
