The Prius mileage is predicated on the use of the electric drive. That is why they get better mileage in the city than on the highway where they have to use the gasoline engine more.
There is a three hour time limit for the 118. miles. The reason we would be willing to allow the Prius drivers to use their mpg displays is because one of them stated that it can be problematic for their Evap system components if they are filled to the rim. Something about a bladder in the system.quote:

Richard, I'm not sure what you are referring to here? Are you saying hybrids and diesels should not be combined?

Re: AMEC Economy Run II and Go-Kart Challenge
Ok I took a perfectly good running high performance B210 engine.......
-and removed the majority of the key components that made it fast. So I am now left with this....
Not as impressive looking, but more appropriate for it's new intended job. This is still the large 1608cc engine and I will be testing this new combination next week. If it falls short of 50 mpg, out it comes and then it will be a big rush to get the 1288 cc engine rebuilt [yes the one I haven't even got yet - Monday I go up on the mountain to dig it out of the woods].

I thought the picture a few posts ago was of the Cobleskill b210. What engine was hanging off that cherry picker?

I decided to sell it and have since picked up a 1st gen CRX with every bolt in front of the firewall removed (he was going to pull and swap the engine)....

Hi Chris,
I have a 3rd gen Civic, which is basically a 4 seat, 1st gen CRX. You may of already found it, but the best resource is www.redpepperracing.com . They have the full shop manual available online and years of forum posts.

You're the only one really paying attention Mark.  That engine pic was a teaser, but it actually might end up being the engine I use. The one you saw pictured is a 1397cc [A14] from a '76 B210 Honeybee. That is the 23-k original engine I've spoken of before. It's under the tool bench covered in plastic.
The '74 1288cc [A13] that I plan to rescue on Monday might end up being a siezed up hulk. We'll soon see.
I am looking into weaker than stock valvesprings. The ultimate economy engine will never see more than 3,000 rpm's. So it should be built so that anything more than that would be in valvefloat. Talk about a hand grenade!

Re: AMEC Economy Run II and Go-Kart Challenge
I am having silly thoughts about removing the heavy starter motor completely and thereby only requiring a 6 lb. motorcycle battery to run the electrical system. How hard can it be to push start a 1,700 lb. car right?
Also considering draining the 90W gear oil out of the transmission and differential and using 50W engine oil in it's place. I've got several quarts of Kendall straight 50W racing oil laying around from my old fuel dragster I used to run.......
Hmmmm, I've got to start thinking about aerodynamics as well. I've got plenty of cardboard around here.
Hope it doesn't rain again!!!!

Re: AMEC Economy Run II and Go-Kart Challenge
Just think if everyone got as fired up as Mike does that’s real enthusiasm! I always like a challenge but have to many at the moment to go as far as you are Mike. I really like it though keep it up and I hope you get it all done! We need to keep an AMEC member on the top of the win list.

Mike, I'm telling you, once you have your cardboard trimmed right, throw it inside of a garbage bag (or even cheap saran wrap) and tape it tight to the card board form. It'll definately hold up through the first rain storm at least (mine went all winter with freezing slush and ice).
As for a smaller battery, not sure how judges would look on it, but another thing that people have done on gassavers.org is to either disconnect (either electrically kill or remove accessory belt) or the bold remove entirely, the alternator. Yes, that's right by removing the drag of the alternator alone people have reported as much as a 17% improvement. Removing the drag and weight (but risking getting stranded) could also be done if you're extreme.
Of course then in my opinion your milage isn't really accurate since you have to start with a fully charged battery and plan your range right and by the end have an empty battery.
Also everyone swears by LED lights and reducing as much electrical load as possible, which I imagine only helps minamilly but any little bit helps.

Re: AMEC Economy Run II and Go-Kart Challenge
That is getting really extreme. I wonder how long a battery would last on a fuel injected car,with the electric fuel pump, the electronic injection system and the electronic ignition.
Accprding to Bosch that would amount to app. 170 watts. Then you have to start the car and every time you hit the brakes another 20 Watts.
So a big enough battery would be heavy taking away some of the advantage.
Tha alternator would only have to produce 14 Amps to cover that load. How much power does that take ?
I'd like to see someone try it.

I'm not going to try it that's for sure.
