Trying to achieve 100 MPG

[rich-green]

I have started a project on my 1991 EFI 1.3 Festiva... I'm installing a fuel enrichment system that incorperates a on board hydrogen/oxygen generator... I'm doing this mod with the help of the h21o.com forum community... If anyone here has suggestion, information, or has done such a mod I'm open to all information, suggestions, and advice...

Looking forward to hearing from you; rich-green

if you want to get 100 mpg you should only go places that are down hill from you, and dont start the car, just coast, i would imagine that you would get great gas mileage lol jk, good luck im kinda curious in this area, but have no idea about it at all

Good luck with the 100 MPG!
Just curious, a Festiva and HHO setup is good for maybe 45-55 MPG (55 being very generous).
How do propose to get the extra 50+ or so MPG out of it?

Good Luck

It may be possible but will take major hypermiling.

I've personally got a best of 75.175 mpg w/ minimal weight reduction,extreme tire pressure,duct tape bumper & fender skirts ,and hypermiling.(coasting, no driving over 50mph.exc.)

I'd say you will need major weight reduction and perfict conditions to acheive your goal.

1959 Opel P-1/T-1, 376 m.p.g. world record, fuel-vapor. The greatest mileage achiever. Rare.
The subject of countless interviews for television, radio, film and print, this is the world-famous and world-renowned Opel Experimental prototype which holds the world record to date for a gasoline-powered vehicle of its size and only mild modification from the original stock pushrod engine. This 1959 Opel achieved over 376 miles per gallon in Wood River, Illinois, in 1973!!
Featured in the Guinness Book of World Records as well as many publications (several of which accompany this car), it had been hidden from the public at the Talladega Motor Museum where is laid to waste for decades. Still clad in its original livery, it is functioning today and would make any collector, museum, special-interest hobbiest or institution proud.
One of the most significant and milestone vehicles of all time, this petroleum-driven vehicle has held the worlds’ record for more than 35 YEARS.

But how did they do it?

I ain't buying it for $300,000 to find out. Although if it could be used on other cars, I would make my money back rather quickly.

I'd rather buy a motorcycle that gets 60-70mpg, and can go where some traffic cant. Time saved is more effective than mpg's these days. Time to yourself to do nothing is (sigh). Anyway 100 mpg out of our car means the car needs to weigh about 800 pounds less, have half the coefficint of drag, and be invisible to cops. the only way my mpg numbers come up enough to notice is when i roll stop signs in second or third gear.

Without being the most cynical guy of the day, please install your parts with lots of documentation for us. It seems that the people doing this to their regular cars are getting half or less the results they say they were going to. They blame that they didnt use all of the "tricks" the company instructed them to use. Ive read some of that documentation. Moving your air pipe, lightening the car, using smaller fuel injectors, driving using a vacuum gauge HEY those have nothing to do with the contraption under the hood! even obtaining good mpg data is hard. Everyone is biased. the only way to really get real time results is to install items on a wife's car or something and just record her distance and consumption. Driving technique makes so much bias.

I just dont like the idea of having this expensive piece that's advertised to take your fuel comsumption by a third, but WONT WORK until you do everything they say. I'd be willing to triple the price of purchase and have them install and tweak everything, and see if my mileage actually goes up past the skew of a few red lights i may chose to run along my route. (red lights at 1am don't scold me) (i work late too NOT drinking)

I would first get 5-10 baseline tanks of your car. Do a tuneup, if no change then your car is healthy. Id then shoot for a number that is obtainable just by driving style. I think people are installing parts THEN behaving differently knowing all the dough they blew better work, so driving better is making the part work to them. I would get an emission test done before installing the parts to get some raw gas analysis. After the HHO is on the car have it tested again. If there is more of a change than what the o2 fooler is doing then that's something to look at.

Fuel vapour sounds like the Pogue carberator I heard about developed a long time ago and that the fuel companys bought the rights to it and shelved it.
Interesting??
Or this Hydroxy Fuel cel my neighbour told me about, http://waterpoweredcar.com/hydrobooster.html

[Kraig]

The Opel is listed as having 495 miles on it..............less than 2 gallons worth of driving...hardly seems enough meaningful data to declare a record...interesting though...Maybe Smokey Yunick copied it for his high mpg hot air motor...

[ignitablepyro]

I've had an HHO generator sitting in the back seat for about a month, I'm gonna get around to installing it sometime soon, thanks for the links they might be helpful for tweaking.

haha, the Pogue.... haven't heard about that since the early 80's! Right up there with the Fish carb. Neither of them worked worth a spit in real world testing. Did great in a lab, but them in temperature extremes, and they're crap. That's why they disappeared, not from some petroluem company conspiracy.

I'm still working on my rooftop hydrogen bladder. The tires were relatively easy, and the rear compartment bladder stays in the car without additional tiedowns.

My next problem is getting that hydrogen into the FI system without the stock fuel pump causing an um..."anomaly."

Then I have to solve the problem of what to replace the hydrogen filled tires with when I use their contents for fuel. Not to mention the lines from them. So far they keep snapping off in treadmill tests. I'm on my fourth treadmill now, too, and I'm running out of money for fire extinguishers.

I can do this! I just need time, and lots of it.

PS: Someone suggested helium, but that just made my car sound really funny. At least I found out it's really hard to burn helium without copious amounts of oxygen and natural gas. Take note, ya'll. Don't waste your time on helium! At least I'm doing the hard work here.

PSS: Someone mentioned pig doodoo. I'm looking for a barn full of pigs now. This could be the breakthrough we all have been searching for! Pigs do fart hydrogen, right? Or was that some cruel joke was posted on the Advanced Hydrogen Propulsion Center's website by "Burns and Meltzitalloff?"

^that's just wrong :p

Plenty of pig doodoo can be found at the capital building in Washington D.C. 435 on one side of the building and 100 on the other side if you can get them all there at one time.

I can't remember the last time that happened, can anyone else?
