Or see it on a dyno

 

I could have done without your post.

 

I ordered a DVD about hydrogen supplementation for gas engines running alternative fuels--ethanol, turpines, CNG, even diesel. Forget about running a renesis on pure H2, I'd like to see what it could do with just 5%~7%. That's all it takes to get the main benefit of H2, which is dramatically higher flame speed. Adding a small bit of hydrogen is like adding lighter fluid to your charcoal to get it lit faster. Yes, the charcoal (gasoline) has more energy, but it lights up relatively slowly. In a best case scenario, a gasoline-air mixture's flame will travel around 5,000 ft. per second. For hydrogen, it's more like 40,000 ft/sec. The difference is dramatic enough that you really need to retard your timing to take full advantage. It has advantages for piston motors, but for rotaries with their elongated combustion chambers, the improvement would be even more dramatic, I'd bet.

BTW, be very sceptial of any device that claims to produce hydrogen on the fly by using the vehicle's 12V power supply. This is most of the H2 supplement kits available right now. They may produce a little H2 (some don't produce any apparently), but it won't be enough to make a difference in combustion--it needs to be at least 5%, thus you need to carry a small H2 tank in your trunk. Or at least that's what this guy says. He goes through the calculations, and even using the most efficient electrolyzers and alternators available, you won't produce a net increase in HP or efficiency.

 

Give me a break. How is it not realy a sports car. You are putting your personal definition on it. How about ok, for a sports car: no rear seat at all, only converables, must have 18" wheels only,...get a life. Mazda added the extra doors to make the car more accessable and maintain the lines of a "sports car". In my book a car with the balance and agility of the RX8 is a true sports car. The 350Z fits your definition and it is not as good a sports car as the 8 (except for the extra hp). Just because the 8 has a useable back seat does not disqualify it from being a sports car. If it will make you happy, I will come weld your back doors shut and rip out your back seat. Poof!! A sports car.

I personally would love to see that, please take his offer!
