Getting the best MPG and alternative fuels (propane/CNG)HHO?

[timok]

I am looking at different EFI kits including this one. It is a duel fuel

Here is a vacuum controlled propane kit that works works with carburetor no electronics or high pressure fuel pumps like EFI.

I have been looking at HHO to boost fuel efficiency and power? Looking at a new standard of efficiency over speed and power with mantling the speed/usability. Making an internal combustion engine more efficient makes more power. Looking at the new fuels standers with methanol/ethanol that pulls water out of the air and the problems that comes with small engines being more sensitive to the lower energy fuels. I am looking at the daily driver with absolute reliability costing lees to operate. Some of the things that I have been looking at to improve reliability/efficiency are oil coolers and water cooled kits. I live in Oklahoma in the normal summer is mid 90's at night and over 100+F during the day. Many of the kits and performance parts increase the compression that limits the fuel that you can use (no 87 octane or methanol/ethanol). Propane loves the higher compression and is still efficient especially with EFI.

EFI kits need amperage to power the ECU, fuel pump, injectors and sensors. HHO need 5 to 6 amps to produce the needed browns gas. Now there are things to get the amperage like LED's and larger stators. I have also looked at comparators over batteries to help with that power issue. Like this but smaller

I am looking for information and help with these ideas. How do you all get more MPG with the new mandated fuels? Offsetting the cost of some of these options as what you will get out on fuel efficiency savings? The new fuel is something that is going to get worse as more methanol/ethanol over the next years. I see countries where methanol/ethanol are all you can get and they are still running the small engines. Are they just accepting the power loose and less MPG along with more maintenance?

I have the ecotron kit the 2 stroke scooterm is mine
My scoot that its on was moded all to hell at the time mag was down to below 30 mph. On the wild 70 cc set up able to do 60 MPH I brought it back up to 45 mph
But you hit the nail on the head big issue was lot enough juice to run the fuel pump I would have to charge the battery every week if I used the ele start at all kick starting I could get just over 2 weeks
I never did get a good run with the higher output stator from a vino

I run nothing but e 10 have no extra maintenance on the carbed scoots or the efi
Here in wi it's been e 10 at just about every station unless it's prem sense 1990
Small engine issues has nothing to do with the ethanol it has to do with there manufacturers cheaping out they used to run just fine with no warnings 20 years ago about not using ethanol furl

You know the model t was originally built to run on pure ethanol

Now let's talk about propane you will loose power with it put a few miles on a car with a propane conversion and it was a dog after the conversion compared to before

Onto cng the first service van I had for kt was a cng it got 2 mpg more on cng then on gas but winter was a pia and then also finding places to fill up with cng
But unless you start with a very expensive engine you will be a dual fuel set up
You will need gas to start it and run it on when it's cold

I found this forum while looking for a water cooled kit. I live in Lawton OK. It is hard to find any active scooter forums. I am loosing use of my legs, needing an automatic to ride so I ride a Honda helix and am going to a lighter 150CC. I have been collecting not running 50 and 150CC scooters to experiment on. It is one of the least expensive method that I can change compression ratio with shims and other variables to learn about engines. One thing is that I am learning is compression and relation to different types pf fuels and the BTU's that they have. I think that fuel efficiency and alternative fuels will become valuable if we have fuel prices like the resat of the world.

Try to find a nice elite 150 the are liquid cooled. I have one and I am thinking about try a note ecotron kit on that I think the charging can handle it but I don't have a manual so haven't found hard numbers

Joe, unless the link has died, I have the Honda Elite 150 manual posted in the manuals thread.
