Updates on the event. Some of the roads that Steve had planned for the 94 mile route were washed away by Irene. So he went back out and re-designed the course. I asked him to add a few more miles as we usually run just over 100 miles or so. Steve says that the updated course measurse out at 105 miles.

Also, the name of the restaraunt we will have lunch and awards at was announced today. it will be at the Freight Yard Restaurant & Pub located at 1 Furnace St. #3, North Adams, MA 01247

Re: AMEC Economy Run events thread


Yesterday's weather was perfect. Most of you know that I usually document the pre-event prep I do to my car[s] for these competitions. I didn't this time, because I simply was way behind and didn't finish it until 4:00 am the morning of the event!

Image
First up was recycling the choroplast belly pan from the B210. The '91 Sentra is longer and a bit wider than the B210 so it isn't quite a full belly pan. This is looking towards the front of the car. On the left you might notice an 18" square section that has been cut out. That's where it caught fire while I was welding the new seat mounts in above it. I was lucky that I had an extinguisher handy and was able to put it out quickly and didn't lose the entire car.

Image
Looking under the tail to the back bumper cover.

Image
Starting to fabricate the side skirts and rear wheel fairings.

Image
These are rear wheel spats, to direct air around the rear tires.

Image
Front end closed in. That is all the air intake this car needs for cooling [I don't have the grill block taped on yet in this pic]. Note how low the edges are left low in front of each front wheel, again to direct air around the [aerodynamically dirty] open front wheels.

Image
New for this year is a roof extension to try to help remedy the customary air flow detachment that all "three box" type sedans suffer from. Hatchbacks and wagons are a better body style for aerodynamics. Ever wonder why the trunk lid lines have been raised higher and higher on sedan bodied cars built in recent years? It's to straighten out the angle of the rear window. They say that airflow generally cannot stay attached to anything more than a 12 degree angle from the roofline down to the rear window. I mocked up the supports from cardboard.

Image
Then I bent them from aluminum strap. I used 3M body moulding tape to attach them to the trunk lid. The lexan sheet was recylcled from the rear window of my old 42D Sentra ice racer.

Image
Complete rear section. Now it was 2:00 am the morning of the event. Enough is never enough so I decided I needed to close in the front wheels as well. So I spent the next two hours fabbing up front wheel fairings. After a shower I got 1 hour of sleep and then it was off to the event. If it looks like the rear lower bodywork isn't finished, that's because it isn't. I wanted to connct the upper to the lower and build a full boat tail but ran out of time.

Image
Ready to go on Sunday morning in Williamstown, MA.

Image

Event results write up coming soon. Gotta take a nap and catch up on some sleep.

Are you sure? The Archer brothers, (Tommy and I forget) used to race Renaults in the Alliance Cup series. One had an Alliance (three box sedan as you put it), the other had the Encore bubble glass hatchback. The two cars were otherwise identical. The Alliance was consistently faster. Acceleration was the same, but terminal speed was different.
The "Kammback" (any relative of yours?) is an intended abrupt break of body to reduce trailing drag. A "three box sedan" is not much more than two "Kamm" shapes in immediate proximity.
There is a range of angles between horizontal (boat tailed) and near vertical (Kamm) that is worse than either of those two. In those situations it it easier to add a horizontal as you did than to cut and fab a vertial (like the Del Sol?)

I discovered why the typically dead-nuts VW odometer on the car I was using was innacurate: The car's owner had installed 195-60-14 tires (that era's Passat size) on the Jetta that was intended to use the 185-60-14. The 2.3% longer "miles" over a 20 mile leg adds up to 1/2 a mile. I was already long past a turn before I was looking for the turn.

But that's still "Driver error" for not checking my equipment (odometer accuracy, GPS batteries, map prints) in advance.

Looks cool. You need to do some coast down test to see which is better.

What, no diffuser ? emoticon

I just dawned on me that I not only drove further (111.3 miles as the trip odometer reported) due to missed turns and backtracking, but that those trip indicated 'miles' are longer a 5280 foot mile. 111.3 trip odo indicated 'miles' works out to 113.9 real-world miles.
Next time I won't depend on the run time of the GPS battery. emoticon

Now for the event story.... and there's always a story. For once I as not the event coordinator and as such some things we always used to do were simply done differently here. For instance, they did not start cars in one minute intervals, after you filled you could leave whenever you wanted. On your return, you could not go to the pump for your refill right away. We had to wait for the event organizer Steve to get back and he got back pretty late. Yadda yadda, suffice to say that our AMEC events are planned better and are run more smoothly. In any case the route was promised to be challenging and it was! More specifically the route instructions were difficult to follow and many people missed turns. Directions were really brief and lacked key details to help you go the right way. Let's just say that if your odometer didn't work, or was inacurrate, you probably had a tough time. And if you missed a turn, your odo is now all wrong too. Steve is a rally guy and this event had quite a bit of rally flavor.

Mount Greylock was exciting but very tricky. They have a 15 mph speed limit! The road is very narrow and has a series of ultra tight hair pin turns. It was difficult for a car like mine with front wheel fairings [you don't want to steer at full lock]. It was also the first economy run event where I had to use engine braking to keep my brakes from overheating. This threw me for a loop as I use an ignition kill switch on the shifter and leave the key on. I didn't realize it until after the event but all the way down the [like 6 mile?] long hill, when I had the spark shut off and thought I was using no fuel at all, I actually was pumping raw fuel through the engine the whole time. You see, if the key is on and the engine is turning, the computer doesn't know that I have disabled the spark. So with the crank agle sensor turning the injectors were firing as usual. I was wondering why I could smell gas all the way down the mountain! I could rewire the switch to shut off the injectors and not the spark, but when would we ever again be in an economy run with hills like that? Never I hope. emoticon

So, with so many people who got lost and went extra mileage, they got penalized because the mpg results were figured on the 105 mile event standard. So if you went 115 miles too bad! During the post event refills, I asked each driver how many miles they actually travelled and used them for my results. So they reflect the actual mpg not the penalized figures.

Please don't get the impression that I didn't enjoy this event, because I did! But I did learn a few things to prepare better for, for next time!

Incidentally, I had a feeling that the Tri-State would not be my best shot for big numbers and figured I'd have to go out again and run our original course though the southern Adirondacks to find out what this car can really do. So that's my plan now. If anyone would like to come out and join me we can have our own little private event. We need to get it done before the weather cools too much. Let me know if you'd like to run with me/us and what Sunday morning works for you.
