Berube's Record

 

 

Dennis gets into the 7's and sets a new NEDRA Record
at SIR in Tucson AZ, December 2007

You can see NEDRA records at http://www.nedra.com/record_holders.html

Here are some graphics that Dennis has on his Current Eliminator - the Altairnano Logo, Kilowatt, A798, Current Eliminator and other decals.

  Here are, (from left to right) Bob Goebel, Vice President Sales and Marketing of Altairnano, Dennis, and an Altairnano Engineer The German Film Crew, they are shooting for a film that will air on German TV. It will be a 45 min segment on Dennis and the CE. When it is edited they will send a link to their website so we can all see it, probably not translated into English!
   


1st run 9.10 @ 142 mph
2nd run 8.43 @ 148 mph
3rd run 8.18 @ 153 mph
4th run 8.007 @ 157mph
5th run 7.956 @ 159mph
6th run 7.963 @ 160.65mph
    I tried to get Dennis in motion, but he was just going too fast

Here is part of what makes it all possible -

The cell itself is quite small as you can see by the hand holding it. The neg and pos aluminum tabs are mechanically clamped together in parallel to a copper bus bar. The bus bars are then connected in series to form the battery pack. There are 8 modules connected in series to make up the battery pack.

     
 
Looking at the stats of the previous run and plugging into the Hairball to set up the the Zilla for the next run.

 

Dennis has a bracket on top of his roll bar. The German film crew mounted one of their cameras there so that they can give us a feeling of what it is like to rolling down the track at 150 mph plus.
 

 

Each of the cell modules has connectors on it so that individual cell voltages can be read. The picture on the left is the top of the battery pack (which is just behind the roll cage). On the left of the picture is a board with bolts wired to a connector, so that when readings of individual cells are needed, all they have to do is plug the boards connector into the battery module. In the picture on the right, 2 of Dennis's pit crew are taking readings of each of cell.

The pack size is 21" long x 13" high x 14" wide - that's only 2.2 cu ft, about the same size as 6 Trojan T-105's

 
.
The 2K Zilla has a cooler. It is filled with ice before each run and after the run it is almost all water. In the photo on the left it is being filled with ice. In the photo on the right the cap is back on the cooler. You can see the business end of the 11" GE motor where the green shroud is. The motor housing is blue
 

 

Here is Dennis's good friend, Jim Ludiker repacking the parachute, a long, tedious job..

On the left is the chute all packed up (black bag at top), you can see the disk brake on the right tire. Notice all the little pebbles on the tires? The tires are so sticky that the pebbles stay on.

 
 
Here's another interesting thing about the tires. When you compare the height of the tires in the photo on the right (taken by the Official Track Photographer) with the one of the tires on the left, you'll see that the tires in the Track Photo have grown and are actually larger. What happens is that as the tires spin up they actually increase in diameter.
 

 

Here is the chain drive that transfers the power from the 11" GE motor. In the same photo, on the far tire you can see a little black spot about 1/2 way up the tire. It is the wear indicator. Since there are no threads to check against Lincoln's head on a penny, there is a small rectangle that goes down about 3/16", when the tread gets down to the bottom, the tire has to be replaced.

The picture on the right shows the crew cleaning off, again, all those pesky little pebbles...

 

 

Dennis has one of his Fluke Meters tie wrapped to the outside of roll cage where it is easily visible while in the pit. The photo on the left is when it was being charged (393.68), on the last run the Altairnano Engineer said 407 V was the max.

The charger is a Miller Welder that Dennis has converted. It starts charging at 37 amps and the backs down slowly to about 14 amps. The lower current actually cools the pack.

 

Here is a shot of the voltage after the CE has done a run, down to 288.93.
The photo on the left shows the Fluke again. The German Film Crew was all over Dennis all the time.

 

 

Here they are wiring up Dennis for sound, I wonder what he is saying as he flys down the track.

 

The good kind of smoke! What a difference in sound when he was up at the line. One of the officials commented that it was nice to be able to talk and not have to shout to be heard.

 

Doing it....

 

 

First run under 8 secs - 7.956 @ 159mph His face says it all!

 

2nd run under 8 secs - 7.963 @ 160.65mph

The pit crew celebrates. Dennis checks again to make sure of his NEDRA record.

I want to thank every body that was there for taking the time to answer my questions. Dennis explained more about how everything works on the CE, the Altairnano people gave us some good insights into their future plans and were very patient with all our *why can't we have them now at a cheap price* questions.

I had a great time and once again it showed me how much can be accomplished when people work towards a common goal. I know it will be a gas to be at the 'Electric Dragin'.

Congratulations Dennis!
