We're just about a week away. I have made a few posts on some motorcycle web sites to try to get a few more bikes to give Ernie Yue's 2008 250cc Ninja some competition. Although Ernie's bike is rated at 60 mpg he managed 73.06 mpg in the last contest even though he had to ride through a mid summer's torrential downpour. He has installed a taller final drive setup and is shooting for 80+ mpg in this contest.

I wish I had the time to do some aero mods to my Datsun B210 before Sunday, but and engine swap is more than enough at the moment.

For those on this forum who haven't been following a similar thread to this on our A.M.E.C. forum, here's what I'm doing to my '77 Datsun B210 for this event.

Previously the car was modified for speed and power. I used it for hillclimbs and such. I built and modified the 1397cc engine to 1608cc's complete with twin 40mm Dellortos...


It ran terrific but only got 25 mpg. OK so I needed a stock engine for economy run events.


So I removed this original 1397cc engine from my '76 B210 parts car. It sat outside in a field for the last 15 years. It needed some TLC.


I tore it down and freshened it up. This was yesterday.


Today it looks like this and I am installing it. I used an '80 Datsun 210 "mpg" cylinder head with it's smaller round intake ports and small combustion chambers. This head, on the B210 block [with it's flat top pistons] yields about 10.4 to 1 compression ratio. High compression is key for improving gas mileage. I'm waiting on an intake gasket from PA, so a road test will have to wait until Wednesday. I will be fine tuning it with an Innovate LM1 wide band oxygen sensor setup. I hope I get it dialed in by Sunday!

This event was a big success and full results are HERE.

Here's the rest of the story on how I prepared my car for this event.


The big engine comes out, the little one goes in....

After bolting it all together, I fine tuned it with an Innovate LM1 wide band oxygen sensor setup. After rejetting the stock Hitachi carburetor for between 14.6 and 15.0 to 1 A/F ratio, I took the car out on a 64 mile test loop the afternoon before the big event. I topped up the fuel tank to the rim and then carefully drove a 64 mile loop. I refilled the tank [right to the rim again] and it took 1.1 gallons of gas. I was very happy to have gotten 56 mpg in this initial test! B210's sit quite high off of the ground and this brings a poor drag coefficient, so I went home that night and tried to help the poor aerodynamics. I added a makeshift front chin spoiler, clear plexiglass headlight covers, and blocked off half of the grill to reduce wind drag.

The next I morning I competed in the A.M.E.C. Economy Run event and carefully drove the 118.7 mile distance. During the post event refill it took only 1.91 gallons of fuel. This equates to 61.53 miles per gallon!

I think we have a new record for the Datsun B210/B310 chassis folks.

This was not my absolute best attempt at fuel mileage for these cars. I would have needed much more time to prepare. There are many other things I can and will try in the future but I don't want to do this with my B210 though. My plan is to take this to the next level with my '81 210 sedan instead. Then I will get into lowering the car for aerodynamics and such.

The event was excellent and the people that we met were terrific. Our record book got pounded. The TDI's cleaned house at over 70 mpg! [This was not a hybrid-friendly course as it was in a mountainous region with speeds between 40 and 55 mph. The average MPG was 49.56! Full results are HERE.

More discussion and pics of this event start on page 25 of THIS thread.

Here are a few of my photos of the event.


We owe it all to these guys for resurrecting this event after 54 years. They took the first steps and created the event from scratch. Dave Burnham on left and Bryon Seyfried on right.


Hobbit, our only Prius driver, but as mentioned earlier in the thread, one of the best in the country. Even as an underdog [given the conditions] he still managed 64.37 mpg, which bettered all of the remaining gas cars.


I wished that we had stickers for the event but ran out of time to have some made. I printed this off at home and taped it to the inside of my glass. My '77 Datsun B210 had it's best ever outing ever. The little 1.4 carbureted pushrod engine cranked out 61.53 mpg.


These are my last minute [literally] and not so good looking aero mods for this event. You can't tell from the picture but there are clear plexiglass headlamp covers there. I opted for only a half grill block due to B210 radiators not being as efficient as modern car's. The air dam was cobbled from a scrap Ford Contour front bumper cover. White duct tape finished the corners off. The B210 sits really high off of the ground. This did hurt the results but I did not have time to lower the suspension. I snapped this picture at 1:30 am. I was so tired I couldn't hold the camera straight.


Bob Addis' New Beetle TDI managed 70 mpg!


I personally checked every car to make sure it was filled to the rim. On several member's car's I had to fill it myself as they gave up early and considered it "full" when it clearly wasn't. Some cars really like to bubble and burp and you have to have patience. After all, if you don't get this part of the procedure right, the rest of it is a farce.

One of the participants used his GPS to graph the elevation changes of the entire 119 miles.



Very nice!

A great time was had by all.

Let us know when run III takes place! I'd like to make it this time.

The time has come.

I'll start another thread with details, but the Adirondack Motor Enthusiast Club's Economy Run III will be on August 23, 2009. If you're in the northeast and you missed the recent Green Grand Prix back in May, you've got another chance. Participants are invited to our club picnic afterwards for awards, burgers and hot dogs on Sacandaga Lake.

You've got two full months to get your vehicles ready for the big
Gas mileage shootout in the Adirondacks!

Great news! I'll have to leave pretty early from Montreal, but it'll be a lot of fun!

[SVOboy]

I think I will be there!

TIME TO BRING THE HEAT

That datsun is so cute. Reminds me of the first car I can remember. My mom had a bright yellow hatchback. I am going to drive my new car to visit New York. Which New York City Hotels and which New York City Attractions should I go to? Any Advice?



***I just bought the Chevy below my post. I love it. Its so cute.
