Thread: A.M.E.C. Economy Run II - Fonda, New York 10/5/08

Greetings fellow Nissan hypermilers. For those of you located in the northeast,
the Adirondack Motor Enthusiast Club
A.M.E.C. will be holding a Fall
Foliage "Economy Run" coming up this October 5, 2008.


A little history: A.M.E.C. held it's first Economy Run back
in 1954. Now 54 years later with record high fuel prices, the club
decided to bring the event back. Our members created a new course and the
event took place this past August 10th. It was very well received and was
thoroughly enjoyed by all who participated. Results can been seen
here.
It was a good dry run to make sure everything went smoothly and that our
laptop excel program worked properly to calculate the results. We enjoyed
it so much that we have planned an "Economy Run II" and this time would
like to open it up to like minded individuals who would like to join us.
To keep it easy to manage and fun we will limit registration to the first
20 entrants.

Here are the details:

What: Fuel mileage contest through the southern Adirondacks
of NY. The route will be on some really nice scenic and challenging roads
and will run 106.3 miles in distance. Your “economic” driving ability
will be tested. Cars will be filled with fuel by an AMEC official and
then weighed on electronic scales. Small ramps are employed for easy on
and off of the scales. Any street legal vehicle is allowed to
participate, [including motorcycles].This event will run rain or shine.

Where: The starting spot will be at the Fairway Oil gas
station on Route 5 in Fonda, NY. [directions below].

When: Sunday, October 5th, 2008. Arrival time will be
8:00-8:30am, first car off at 9:00am. They have gas and diesel and have a
large enough parking lot that we won’t be in the way. (They also don’t
use ethanol, if that makes a difference to anyone.)

Cost: $10 per vehicle

Awards include:

1. Best overall mpg for gas cars

2. Best overall mpg for diesel and hybrid cars

3. Best ton-mile per gallon [TMPG] vehicle weight in pounds, divided by
2000, times miles driven, divided by gallons consumed. A handy calculator
is here.

4. Best carbureted mpg

5. Best miles per dollar. [Based on the actual cost to travel the 106
miles. For example, we had a diesel VW Jetta get 56 mpg and a Dodge
Avenger get 48 mpg. Because the diesel fuel was about a dollar more per
gallon than the gasoline, the Avenger won this contest.]

Note: If we get more than one motorcycle we will add a class for them.

Awards: This event will conclude about noon, and our plan
is to proceed up the nearby Checkers Out Go-Kart track for lunch, awards,
and optional indoor go-kart races if you so desire. Checkers Out Speedway
is an indoor go kart track open year round, and is located about ¾ of a
mile south of Johnstown, NY, on NYS Route 30A. Physical address: 2299
State Hwy 30A Johnstown, NY 12905. Track phone: 518 736-4630

Directions: to Fairway Oil gas station: Take NY Thruway Exit 28.
After the toll booth, turn left onto Riverside Drive. Then turn right
onto South Bridge Street and go over the bridge. On the other side of the
bridge is a traffic light. You can see Fairway Oil and Gas on your left.
Turn left onto Route 5 and enter the station.

To register for this event: Please contact Mike Kamm at (518)
674-0520 or via email: mkamm [at ] juno [ dot] com. Or just simply reply
to this thread with your name, year/model car. There is also a message
board thread regarding this event on the A.M.E.C. message board

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

Here's how I prepared my car 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.


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 10.5 to 1 compression ratio. High compression is key for improving gas mileage.


Other than the Pacesetter header and 2" mandrel bent exhaust system, the reast of the drivetrain is stock.


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 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.

Really really cool project.

did you build a loose motor? bearing and piston ring clearances.
The B210 looks clean.
Good luck with your efforts and the next event.

Thanks SERacer,

No I didn't change any clearances, but I did reuse the main and rod bearings and the "looser" front and rear crank seals. No leaks either.
Mike

Wow, just realized I never updated this thread. Well, I made further modifications to the B210 and got 77.04 mpg at the next event! Then, I turned to my '93 SE-R to see what could be done with one of our cars.


How about 60.73 mpg!

The thread about the contests I entered with both cars can be seen here. Lots of details on how I did it as well.

Enjoy,

Mike

Sick!

Stratton.
