How about 559/607 on Hydrogen? We have been doing some research for our parent company (Quantum-Tecstar - http://www.qtww.com/index.php ) using hydrogen as fuel. With many hours of dyno testing and some big brains hard at work, we were able to get to 559hp and 607tq on the engine dyno yesterday. This is with a small turbo on a 402 LS2 engine. Peak hp was at 5000rpm and still climbing when we lifted and peak torque was at 4500 rpm.
Before you say, "So what?", do a little research and see if anyone else is anywhere near these numbers on straight hydrogen. Last we heard our nearest competitor was at around 200 hp and could not make a pull past 4500rpm.
The setup uses a lot of fuel, thus is not really feasible at this time for any practical use. This has been the major downside to hydrogen fueled vehicles. Fuel consumption is so large and there is no safe way to store the required fuel. To make this kind of power requires 2 specially made injectors per cylinder (produced by Quantum).
So the bottom line is this, decent power can be had on hydrogen, and when Quantum figures out the rest of the equation, we will be here to build your hydrogen-powered setup!

hows the emissions on that kind of engine? I was reading up a little and saw that its possible it releases toxic water from the burn. Even though it consumes alot, what is the price per gallon advantage? And are there any predictions as to mpg compared to gas yet? What kind of steps are being taken to reduce the amount of hydrogen needed to power a vehicle like that?
sorry for all the Q's, ive been really interested in hydrogen. I have family working for delphi and few other gm devisions doing alternative fuel research and im always lookin at the latest advancements. keep at it!

The emissions output on this type of fuel is just short of amazing, you can not see anything but water coming from the tailpipe.
Price is a disadvantage at this time. It takes about 200 dollars worth of hydrogen for me too dyno for 1 hour. One of our Hydrogen Hummer H2's will only go about 60 miles on a full tank, and that tank would be over 50 dollars to fill.
It is a gaseous fuel like CNG or propane, so its rates would be in PSI rather than gallons. It is not "good on gas" so to speak, but the planet will like it much more than gasoline.
Hydrogen is in its begining learning stages, we are helping to write the book so to speak now. We are mostly working with power adders to find the limits of the fuel.

Thats the same thing everybody says at first(myself included), but then I think of the guys in the 1900's when they told there friends "I'm going to take this flamable liquid we call gas, compress it with a piston, then spark will make it explode and push a crankshaft into a circular motion", I'm sure everbody said "your going to WHAT".
It does have some handling issues to do with its high pressure that command respect. It also lights very easy, so it can make you pull your hair out tuning it.

congrats on your acomplishment.
very interesting stuff.
now if you could just build a converter that converts water to hydrojen just before it gets injected.
not sure if this is a scam or not but i found this product intertsesting

not sure about that link. Looks somewhat promising i guess.
Kurt, does Quantum-Tecstar feel hydrogen is the best alt fuel of the future? As in, most of their R&D is spent in that area versus hybrid, fuel cell, or biodiesel? Is it possible we'll be seeing hybrid hydrogen setups in production?

When bringing up the pressure in the cylinder, are you finding it lights off and burns rapidly but without detonation -- or does it want to just pop and do no work? I've been able to locate enough believable information on engines running hydrogen at low pressures, but nobody I knew of was doing forced induction 
Not sure how realistic it will be, we just have a customer with a hp goal we are trying to reach so the fuel testing landed here.

Detonation has not been a problem with this fuel, it has a lot in common with a high speed boosted diesel. One of the problems is getting enough in the cylinder. I have 16 injectors in the intake now, when I flowed the injectors on gas, they flowed over 300 pounds a hour. With that kind of flow I am using more cylinder correction than normal and it is changing with rpm. I am currently working on a 24 injector intake that will use one BS3 with staged injection(currently using) and one 8 driver std BS3 LS box on the same engine. Playing with boosted hydrogen is fun!!

the efficiency is the biggest problem with alternative energy sources. solar cells, hydrogen, and so on. the hardest part of the hydrogen is how to produce it. the way the do it now is still with hydrocarbons which defeats the purpose of alternative energy. CH4 + H2O --> CO + 3H2
also reacts CO + H2O --> CO2 + H2
also reacts CO + H2O --> CO2 + H2
I can see getting it in the cylinder being a real headache. I just did some reading around on the 'net and looked at a pressure/density table. If you're injecting into the intake, its amazing you're getting enough volume in there and have it still travel toward the cylinder -- and making well over 500 HP!
I found more info about flame speed too, one article I found mentioned it was around 5% to 10% the speed of gasoline!
